Billing and credentialing services are the combined administrative processes that enable healthcare providers to enroll with insurance payers, verify their professional qualifications, and submit clean claims for accurate reimbursement. These services form the operational foundation of every healthcare practice’s revenue cycle—connecting provider enrollment, payer contracting, charge capture, and claims management into one integrated system.

Yet most practices underestimate what’s at stake. Credentialing delays cost the average physician over $50,000 in lost revenue, according to recent industry data. Initial claim denials reached 11.8% in 2024 — up from 10.2% just a few years earlier—and 86% of those denials are potentially avoidable. The financial damage compounds quickly: U.S. physicians collectively lose an estimated $125 billion each year from billing errors alone. For medical billing and credentialing services, precision is not optional—it is the difference between a thriving practice and one hemorrhaging revenue.

Here is what many providers miss: medical billing and credentialing are not two separate back-office functions. They are one interconnected revenue system. When credentialing breaks down—an expired enrollment, a mismatched NPI, a lapsed revalidation—billing breaks down with it. Claims rejected. Payments stall. Patients receive surprise bills. And when billing is inaccurate, even flawless credentialing cannot protect your cash flow. This is why leading practices treat revenue cycle management services as a unified discipline, not a collection of isolated tasks.

In this guide, you will learn exactly what credentialing and enrollment services involve, how the process works step by step, the 2026 regulatory changes affecting every practice, real cost and timeline data backed by official sources, and how to evaluate whether outsourcing is the right decision for your organization.

At Pro-MedSole RCM, our credentialing and billing specialists manage this entire lifecycle for practices nationwide—from initial CAQH setup and payer enrollment through clean claim submission and denial resolution.

What Is Credentialing in Medical Billing?

Credentialing in medical billing is the formal process of verifying a healthcare provider’s qualifications—including education, training, licensure, board certifications, and malpractice history—to meet an insurance payer’s requirements for network participation. It involves primary source verification, payer-specific application submission, and committee review. Healthcare providers must complete credentialing with each insurance payer individually to bill that payer as an in-network provider and receive contracted reimbursement rates.

To understand medical billing credentialing fully, it helps to break the process into its two core phases.

The first phase is credential verification. During this stage, the payer or its designated credentialing verification organization (CVO) performs primary source verification (PSV) on the provider’s qualifications. This means contacting issuing institutions directly—medical schools, state licensing boards, the National Practitioner Data Bank (NPDB), specialty board certification organizations, and malpractice insurance carriers—to confirm that the provider’s self-reported information is accurate. The NCQA (National Committee for Quality Assurance) defines its credentialing focus areas as credential verification and ongoing monitoring of sanctions and complaints, setting the standard most commercial payers follow.

The second phase is contracting. Once the payer’s credentialing committee approves the provider’s verified application, the practice receives an in-network participation agreement. This contract includes the negotiated fee schedule, CPT-code-specific reimbursement rates, and the terms governing the provider-payer relationship. Until contracting is finalized and the provider has an effective date, no in-network billing can occur.

Most payers rely on the CAQH Provider Data Portal to collect and access provider credentialing data. With more than 2.5 million providers actively maintaining their profiles in CAQH ProView—a single credentialing application accepted or supported in all 50 states—it has become the industry-standard utility for credentialing in medical billing.

Why Credentialing Directly Impacts Your Revenue

The connection between credentialing and revenue is not abstract—it is mathematical. Providers who are not credentialed with a payer simply cannot bill that payer as in-network. This means patients using that insurance plan face higher out-of-pocket costs at your practice, which drives them to competitors who are in-network. In today’s marketplace, where patients increasingly select providers based on insurance compatibility, a credentialing gap is a patient acquisition gap.

This reality makes billing and credentialing services a revenue protection strategy, not just an administrative requirement. Every week a provider remains uncredentialed with a major payer is a week of lost appointments, lost referrals, and lost revenue that no amount of marketing can recover.

The Two Types of Credentialing Every Provider Should Know

Not all credentials in medical billing serve the same purpose. There are two distinct types, each with different requirements and outcomes:

1. Institutional credentialing (hospital privileging)—Performed by hospitals and health systems to grant a provider medical staff membership and clinical privileges. This determines what procedures a provider can perform within a specific facility. Hospital credentialing committees evaluate clinical competency, peer references, case volume, and outcomes data.
2. Payer credentialing (insurance panel enrollment)—Performed by insurance companies to approve a provider for network participation. This determines which insurance plans a provider can bill as in-network. Payer credentialing focuses on licensure, education, malpractice history, sanctions screening, and network adequacy needs.

Most providers need both types. A surgeon, for example, must be credentialed with the hospital to perform procedures and credentialed with each payer to be reimbursed for those procedures. When either credentialing type lapses, the financial consequences are immediate.

Term	What It Means	Who Performs It	Key System / Tool	Typical Timeline
NPI Registration	Obtaining a unique National Provider Identifier required for all HIPAA-standard transactions	Provider applies through NPPES	NPPES (CMS)	1–10 business days
Credentialing	Verification of qualifications — education, licensure, board certifications, malpractice history, work history, sanctions screening	Payer or facility credentialing committee	CAQH ProView, NPDB	60–90 days
Provider Enrollment	Registration in the payer’s billing and claims processing system so claims can be adjudicated	Payer (CMS manages Medicare enrollment)	PECOS (Medicare), individual payer portals	30–90 days
Contracting	Negotiation and execution of an in-network participation agreement that includes fee schedules and reimbursement terms	Payer contracting department + provider/practice	Payer contract documents	30–60 days
Revalidation	Periodic re-verification to maintain active enrollment and uninterrupted billing privileges	CMS (Medicare) or commercial payer	PECOS	Every 3–5 years (DMEPOS every 3 years)

These five stages often overlap and run in parallel, but each one must be completed for a provider to bill a payer as in-network. Missing even one step—an outdated NPI taxonomy code, an unsubmitted enrollment application, or a contract that was never executed—creates a break in the revenue cycle that results in denied claims, delayed payments, or worse, retroactive recoupments.

When providers hire billing and credentialing services, the expectation is that the service partner manages all five stages as one integrated workflow. This is why the term “credentialing and enrollment services” is used holistically in the industry—because these steps only produce revenue when they function together without gaps.

At Pro-MedSole RCM, we manage every phase of this workflow. From initial NPI verification through ongoing revalidation tracking, our specialists ensure that no provider on your roster ever has a gap in their billing privileges. Each application is tracked in real time, follow-ups are executed weekly, and every milestone—from CAQH completion to effective date confirmation—is documented and reported to your practice.

Managing credentialing, enrollment, and contracting simultaneously is overwhelming for most practices. Pro-MedSole RCM handles every phase—talk to a specialist today.

How Long Does Medical Credentialing Take?

Medical credentialing typically takes 90 to 180 days from application submission to effective date. That timeline depends on the payer type, your specialty, and whether your application package is complete when it’s submitted. Medicare enrollment through PECOS generally lands in the 60 to 90 day range. Commercial payer credentialing runs longer, often 90 to 150 days. And hospital privileging? That can stretch to six months depending on the facility’s medical executive committee schedule.

Here’s what those timelines look like broken down by payer:

Payer Type	Average Timeline	Key Factors That Affect Speed
Medicare (via PECOS)	60 to 90 days	CMS-855 form accuracy, revalidation history, whether a site visit is triggered
Medicaid	90 to 120 days	Varies significantly by state; some states carry backlogs of 4+ months
Blue Cross Blue Shield	90 to 120 days	Varies by state affiliate; some require separate applications per state plan
UnitedHealthcare/Optum	60 to 90 days	Heavily CAQH-dependent; Optum portal required in some regions
Aetna	90 to 120 days	Committee review cycles run monthly; specialty panels may have limited openings
Cigna	60 to 120 days	Regional variation; network need assessments can slow down acceptance
Hospital Privileging	90 to 180 days	Medical Executive Committee meets monthly; board approval adds another cycle

Those are averages. Your actual timeline could be shorter or significantly longer depending on factors you can control, and a few you can’t.

What Causes Credentialing Delays?

Five issues cause most of the delays we see, and four of them are preventable:

1. Incomplete CAQH profiles or missing documentation. A single missing malpractice certificate or an unattested profile can stall an application for weeks.
2. Slow primary source verification responses. Medical schools and licensing boards don’t always respond quickly, especially during peak enrollment periods.
3. State licensing board backlogs. Some states take 60+ days just to verify an active license. You can’t speed that up.
4. Payer committee review cycles. Most credentialing committees meet once a month. Miss the cutoff by a day, and you wait another 30 days.
5. Incorrect NPI or taxonomy code information. A mismatched taxonomy code between NPPES and the payer application triggers a rejection before review even begins.

These delays aren’t just inconvenient. According to industry data, credentialing delays cost the average physician over $50,000 in lost revenue. Multiply that across a group practice adding three or four providers, and you’re looking at real financial damage. Medallion’s 2026 State of Credentialing Report found that many hospital organizations now report more than $1 million in annual revenue risk driven by these day-to-day credentialing setbacks.

At Pro-MedSole RCM, our credentialing specialists submit complete, verified application packages from day one. We track every application weekly, escalate delays before they become revenue gaps, and maintain direct relationships with payer enrollment departments. That’s what professional billing and credentialing services should look like: proactive management, not passive waiting.

How Much Do Credentialing Services Cost in 2026?

Credentialing services typically cost between $150 and $300 per provider per payer application when outsourced to a professional RCM company. In-house credentialing costs significantly more: approximately $7,000 to $8,000 per provider when you factor in staff salaries, software subscriptions, and administrative overhead. That gap gets wider the more providers you’re managing.

In-House vs. Outsourced Credentialing: What’s the Real Cost?

Here’s how the numbers actually break down:

Cost Factor	In-House Credentialing	Outsourced (Professional RCM Partner)
Staff salary	$43,558/year (average credentialing specialist)	Included in service fee
Per-provider organizational cost	$7,000 to $8,000	$150 to $300 per payer application
Software and CAQH tools	Additional subscription costs	Included in engagement
Revenue lost to enrollment delays	$50,000+ per provider	Minimized through proactive follow-up
Scalability	Hire more staff = more fixed cost	Scales without adding overhead
Medicare enrollment fee	$750 (2026 CMS fee, paid by provider)	$750 (same CMS fee, it’s fixed regardless)

The CMS Medicare enrollment application fee of $750 is set by CMS and applies whether you handle enrollment in-house or outsource it. That cost doesn’t change. What changes is everything around it.

The real cost comparison isn’t about the line items, though. It’s about the return. If credentialing delays cost your practice $50,000+ per provider in lost revenue, and outsourcing costs a fraction of that per application, the math isn’t complicated. Factor in that 86% of claim denials are potentially avoidable, and that many denial root causes trace directly back to credentialing errors, incorrect enrollment data, or expired payer participation, and the ROI of professional credentialing and billing services becomes hard to argue against.

When practices tell us they’re handling credentialing internally to save money, we usually find they’re spending more than they realize. They just aren’t tracking the full cost.

The Hidden Revenue Killer: How Credentialing Errors Drive Claim Denials

Here’s the part most practices don’t see until it’s already cost them money: billing and credentialing aren’t parallel functions running on separate tracks. They’re one system. When credentialing data is wrong, claims fail. When enrollment lapses, payments stop. The connection between credentialing accuracy and billing success is direct, measurable, and often overlooked.

Initial claim denials hit 11.8% in 2024, up from 10.2% just a few years earlier. 86% of those denials are potentially avoidable, according to industry analysis. That means the vast majority of denied revenue traces back to correctable errors, and a significant portion of those errors start in credentialing.

The Financial Impact of Billing Errors and Denials

The numbers are hard to ignore:

• U.S. physicians lose an estimated $125 billion annually from billing mistakes
• Hospitals lose approximately $262 billion annually from denied claims
• Recovering a single denied claim costs roughly $118 in administrative appeal expenses
• Administrative costs related to billing represent 25% of U.S. hospital spending
• Between 49% and 80% of medical bills contain at least one error

The CMS 2025 CERT Supplemental Report, released January 24, 2026, puts a finer point on where Medicare money is lost. The Medicare Fee-for-Service improper payment rate was 6.55%, totaling $28.83 billion in projected improper payments. The breakdown of what’s driving those losses tells you exactly where to focus:

Error Category	Percentage of Total Improper Payments
Insufficient documentation	53.0%
Medical necessity	15.3%
No documentation	12.0%
Incorrect coding	11.1%
Other	8.5%

More than half of all improper payments come down to documentation. Not fraud. Not complex coding disputes. Missing paperwork.

How Credentialing Gaps Cause Billing Failures

The mechanisms are specific and predictable. If you’ve worked in billing long enough, you’ve seen every one of these:

Wrong NPI or taxonomy code on the claim. The clearinghouse kicks it back before it even reaches the payer. The provider’s enrollment record says one taxonomy code; the billing system has another. Automatic rejection.

Expired or lapsed enrollment. The payer’s system returns the claim as “provider not found” or “not eligible to bill.” The provider’s enrollment lapsed during revalidation, and nobody caught it.

Services rendered before credentialing effective date. The provider started seeing patients before their enrollment was finalized. Retroactive billing gets denied by most payers. That revenue is gone.

Telehealth multi-state credentialing gaps. A provider is credentialed in one state but seeing telehealth patients in another. The payer denies the claim because enrollment doesn’t cover the patient’s state. Telehealth-related denials rose 84% in 2025, according to MDaudit’s analysis. The average denied amount for Medicare Advantage claims rose 22.4% to approximately $1,000.

Stale provider directory data. The No Surprises Act requires directory updates every 90 days. Outdated information creates patient billing disputes and payer compliance flags.

Every one of these scenarios starts with a credentialing problem and ends with a billing failure. That’s why integrated billing and credentialing services exist: to create a closed loop where credentialing feeds accurate data to your medical billing team, and billing feedback identifies credentialing gaps before they turn into revenue problems. At Pro-MedSole RCM, our denial management team works directly with our credentialing specialists to catch and resolve these issues in real time, not after the revenue is already lost.

Credentialing and Billing Compliance: What Changed in 2025 to 2026

The credentialing and billing compliance landscape shifted significantly over the past 18 months. If your credentialing workflow hasn’t changed since 2024, it’s out of date. These aren’t minor policy tweaks. They’re structural changes to how often you monitor providers, how quickly you must complete credentialing, and what happens if you fall behind.

NCQA Credentialing Standards Overhaul (July 2025)

NCQA rolled out the most significant update to credentialing standards in years, and it took effect July 1, 2025. The biggest change: healthcare organizations must now review every provider every 30 days. Not every two to three years during recredentialing. Every month.

Monthly reviews cover license status, OIG exclusion screening, state medical board actions, and SAM.gov checks. Miss a month, and you’ve got a compliance gap.

NCQA also shortened the credentialing completion windows. Accredited organizations went from 180 days down to 120 days. Certified organizations went from 120 days down to 90 days. That’s a significant compression for teams already stretched thin.

This shift from periodic recredentialing to continuous monitoring changes the staffing math for every practice. What used to be a quarterly task is now a monthly obligation with documentation requirements.

CMS PECOS and Enrollment Updates for 2026

CMS didn’t stand still either. PECOS received upgrades that added new provider-based location categories, including off-campus and mobile units. Facilities, especially skilled nursing homes, now face strengthened ownership and disclosure requirements.

The enforcement side tightened too. Providers must report adverse actions, ownership changes, and practice location updates within 30 days of finalization. Miss that window, and CMS can pursue retroactive revocations. Not prospective. Retroactive. That means claims you already submitted and got paid on could be clawed back.

The 2026 Medicare enrollment application fee holds at $750.

No Surprises Act: Provider Directory Requirements

Under the No Surprises Act, providers must verify and update their provider directory information every 90 days. Non-compliance can result in penalties or directory suppression, meaning patients searching for in-network providers won’t find you even if you’re technically enrolled.

This creates an ongoing credentialing maintenance obligation that most practices don’t have dedicated staff to manage. Someone has to verify directory data across every payer, every quarter. That’s a real workload on top of everything else.

The era of “set it and forget it” credentialing is over. Monthly monitoring, shorter completion windows, and stricter enforcement mean practices need dedicated rcm credentialing infrastructure. You either build that internally or partner with a team that already has it. Pro-MedSole RCM’s billing and credentialing services include all of these ongoing compliance requirements as standard, not as add-ons.

Why Healthcare Providers Outsource Billing and Credentialing Services

Some practices handle credentialing internally, and for a solo provider with two or three payer relationships, that can work. But as your practice grows, adds providers, expands into new states, or takes on telehealth, in-house credentialing becomes a full-time job. It pulls clinical and administrative staff away from patient care and buries them in applications, follow-ups, and compliance tracking they weren’t hired to do.

5 Reasons Practices Outsource Credentialing

1. Scale without adding overhead. Every new provider means 8 to 13 new credentialing applications across different payers. A professional service manages all of them without you hiring another credentialing and billing specialist. The average physician maintains relationships with 13 different organizations, each with unique requirements.

2. Faster credentialing cycle times. Dedicated credentialing teams with established payer relationships and submitted-application volume move applications through the process faster than in-house staff who split their time between credentialing and 10 other responsibilities.

3. Eliminate revenue gaps from delays. Credentialing delays cost the average physician over $50,000 in lost revenue. When you outsource medical billing and credentialing services, proactive follow-up and escalation protocols close those gaps before they drain your cash flow.

4. Stay compliant without hiring compliance staff. NCQA’s monthly monitoring requirements took effect July 2025. That means someone needs to run OIG, SAM.gov, and state board checks on every provider, every 30 days, and document it. Most practices don’t have the infrastructure for that.

5. Reclaim your team’s time. The U.S. healthcare system spends $83 billion annually on administrative transactions between providers and payers, according to the CAQH 2025 Index Report. Outsourcing credentialing and billing gives your staff hours back every week to focus on what they were actually hired to do: take care of patients.

Credentialing Services for New Practices

New practices face a credentialing problem that established groups don’t think about: you can’t bill until you’re enrolled, and you can’t see insured patients until you can bill. That creates a 90 to 180 day revenue gap at the most financially vulnerable point in your practice’s life.

You’re paying rent, staff salaries, and equipment costs from day one. Revenue doesn’t start until credentialing is complete. For new practices, outsourcing billing and credentialing services isn’t a convenience. It’s the difference between surviving that startup window and running out of cash before your first in-network patient walks through the door.

Pro-MedSole RCM offers new-practice credentialing packages designed to get you paneled with your highest-priority payers first, so revenue starts flowing as early as possible while we work through the remaining applications in parallel.

Specialty Credentialing: From Mental Health to Telehealth

Credentialing requirements aren’t one-size-fits-all. A behavioral health practice navigating closed payer panels faces a completely different set of obstacles than an orthopedic group applying for hospital privileges. Telehealth adds another layer entirely, with multi-state licensing requirements that didn’t exist five years ago. The specialty you practice and the delivery model you use shape every part of how billing and credentialing services work for your organization.

Physician Credentialing Services

Physician credentialing services cover the full scope of MD and DO enrollment across every specialty: primary care, cardiology, oncology, orthopedics, neurology, gastroenterology, general surgery, and beyond. Each specialty carries its own verification requirements.

Board certification verification is specialty-specific. A cardiologist’s ABIM certification gets verified differently than a surgeon’s ABS status. DEA registration must match the provider’s practice location and state. Hospital privilege confirmation adds another step for providers who need admitting rights or want to perform procedures at affiliated facilities.

The common thread across all physician credentialing is volume. Most physicians need enrollment with 10 to 15 payers, and each application follows its own timeline and documentation rules.

Mental Health and Behavioral Health Credentialing

Behavioral health credentialing has its own set of headaches. Psychologists, licensed professional counselors (LPCs), licensed clinical social workers (LCSWs), licensed marriage and family therapists (LMFTs), psychiatrists, and addiction counselors all face payer-specific scope-of-practice requirements that determine what services they can bill for.

Here’s where it gets tricky: many commercial payer panels for behavioral health are closed or have limited openings. Getting denied isn’t always about your qualifications. Sometimes the panel is simply full in your geographic area, and you need to file a credentialing appeal or wait for an opening.

Medical billing for mental health also uses different CPT code families than most medical specialties. Codes like 90834 (individual therapy, 45 minutes), 90837 (individual therapy, 60 minutes), and 90847 (family therapy) have specific documentation and time-based requirements that your billing team needs to understand from day one.

Telehealth Credentialing: Multi-State Requirements

Telehealth created a credentialing problem that didn’t exist at this scale before 2020. If a provider sees patients across five states via telehealth, that means five separate license verifications, five background checks, and potentially five separate payer enrollment applications per insurance company.

The Interstate Medical Licensure Compact (IMLCC) now includes 42 member states, which streamlines physician licensure across state lines. That helps with licensing. But here’s what catches most practices off guard: the IMLCC does not streamline payer credentialing. You still need to enroll with each payer in each state separately.

The billing consequences are real. Telehealth-related denials rose 84% in 2025. The primary driver is credentialing misalignment: a provider is enrolled and credentialed in their home state but sees a patient in a state where their payer enrollment isn’t active. The claim gets denied. The revenue disappears.

Pro-MedSole RCM manages multi-state telehealth credentialing end-to-end, tracking licensure, payer enrollment, and state-specific requirements across every state your providers practice in.

Group Practice and Facility Credentialing

Group practices and facilities add organizational complexity on top of individual provider credentialing. Group enrollment requires CMS-855B for Medicare, with separate reassignment forms (CMS-855R) linking each individual provider to the group’s billing NPI.

Adding or removing providers from a group roster requires timely updates to every payer. Miss an update, and the new provider’s claims get denied. Remove a departed provider too late, and you’ve got a compliance issue.

DME suppliers operate under different rules entirely: CMS-855S applications, three-year revalidation cycles instead of five, and surety bond requirements. Facility credentialing for ambulatory surgery centers and urgent care clinics follows yet another pathway, often requiring a credentialing and billing specialist who understands both the provider enrollment side and the facility licensure side.

Insurance Credentialing Services: Getting Paneled with Major Payers

Insurance credentialing, also called payer credentialing or provider panel enrollment, is the process of applying to join a health plan’s provider network. Every payer runs its own application process with its own committee review timeline, documentation requirements, and contract terms. Knowing the nuances of each payer saves weeks of back-and-forth and prevents avoidable application rejections.

Medicare and Medicaid Enrollment

Medicare enrollment goes through PECOS, or through paper CMS-855 forms if electronic submission isn’t feasible. The 2026 application fee is $750, set by CMS regardless of whether you handle enrollment internally or outsource it.

CMS applies risk-based screening levels to enrollment applications: limited, moderate, or high. The screening level determines how much verification CMS performs, including potential site visits for higher-risk categories. Revalidation is required every five years for most provider types and every three years for DMEPOS suppliers. CMS posts revalidation due dates seven months in advance, and contractors send notices three to four months before the deadline.

Miss your revalidation window, and CMS deactivates your enrollment. During that deactivation period, Medicare won’t reimburse a single claim. With nearly 98% of U.S. physicians enrolled in Medicare, keeping PECOS data accurate isn’t optional.

Medicaid enrollment is state-specific. Each state runs its own enrollment portal, and managed care plan participation requirements vary. Some states process Medicaid applications in 60 days. Others carry backlogs that push timelines past four months.

Commercial Payer Credentialing

Each major commercial payer has credentialing quirks that catch practices off guard if you haven’t been through the process before:

• Blue Cross Blue Shield operates as 36 independent companies. Being credentialed with BCBS in one state doesn’t carry over to another. Each affiliate requires a separate application.
• UnitedHealthcare/Optum is the largest commercial payer and relies heavily on CAQH for credentialing data. Some regions route enrollment through the Optum portal instead of the standard UHC process.
• Aetna (CVS Health) conducts network need assessments in saturated markets. Your application can be denied not because of your qualifications, but because Aetna has decided they don’t need more providers in your specialty in your area.
• Cigna has significant regional variation in credentialing processes. What works for Cigna enrollment in Texas may not apply in Pennsylvania.
• Humana focuses heavily on Medicare Advantage plans and has specific enrollment requirements for providers who want to participate in those products.
• TRICARE serves military families and follows a distinct credentialing pathway separate from commercial and government payers.

Pro-MedSole RCM maintains active relationships with all of these payers and understands the enrollment nuances for each one. Our credentialing and enrollment services team has the payer contacts, application expertise, and follow-up systems to get your providers paneled without the guesswork. That’s what professional billing and credentialing services look like when they’re done right.

Frequently Asked Questions About Billing and Credentialing Services

What is credentialing in medical billing?

Credentialing in medical billing is the process of verifying a healthcare provider’s qualifications, including education, training, licensure, board certifications, and malpractice history, to meet a payer’s requirements for network participation. Once credentialed, the provider can bill that payer directly as an in-network provider, receiving patient referrals and contracted reimbursement rates.

How long does the credentialing process take?

The credentialing process typically takes 90 to 180 days depending on the payer. Medicare enrollment through PECOS averages 60 to 90 days. Commercial payers like Blue Cross Blue Shield, UnitedHealthcare, and Aetna generally take 90 to 150 days. Delays most often result from incomplete CAQH profiles, missing documentation, or slow primary source verification responses from medical schools and licensing boards.

Are credentialing services worth it?

Yes. Credentialing delays cost the average physician over $50,000 in lost revenue, and handling credentialing in-house runs approximately $7,000 to $8,000 per provider when you factor in staff salaries, software, and administrative overhead. Professional credentialing services typically cost $150 to $300 per provider per payer application. The return on that investment is overwhelmingly positive, especially for growing practices adding new providers.

Can I do my own credentialing?

You can, but it’s getting harder every year. The average physician maintains relationships with 13 organizations, each with unique credentialing requirements and timelines. NCQA’s 2025 updates now require monthly monitoring of every provider’s license status, OIG exclusions, and state board actions. For practices with multiple providers, self-credentialing becomes a full-time job that pulls staff away from patient care and revenue-generating activities.

What are the two types of credentialing?

The two main types are institutional credentialing and payer credentialing. Institutional credentialing is performed by hospitals and health systems to grant providers specific clinical privileges at their facilities. Payer credentialing is performed by insurance companies to approve providers for network participation and in-network billing. Most providers need both types throughout their careers.

What documents are needed for credentialing?

Required credentialing documents typically include:

• Current state medical license(s)
• DEA registration certificate
• Board certification documentation
• Medical school diploma and residency or fellowship certificates
• Current malpractice insurance certificate
• CV or work history covering at least five years
• Three professional references
• NPI confirmation from NPPES
• W-9 form
• Government-issued photo ID
• Hospital privilege letters, if applicable

What happens if a provider is not credentialed?

An uncredentialed provider can’t bill insurance payers as in-network. Services are either billed at lower out-of-network rates with higher patient costs, or denied entirely. This leads to direct revenue loss, patient attrition to in-network competitors, and potential No Surprises Act violations. If Medicare enrollment lapses, CMS deactivates billing privileges, and Medicare won’t reimburse a single claim during the deactivation period.

Do you need a degree to be a credentialing specialist?

A formal degree isn’t always required, though most employers prefer candidates with at least an associate’s degree in healthcare administration or a related field. Industry certifications carry significant weight. The Certified Provider Credentialing Specialist (CPCS) credential from NAMSS is the most recognized certification and improves both job prospects and earning potential in the credentialing field.

Billing and credentialing services aren’t an administrative nice-to-have. They’re revenue infrastructure. In an environment where initial claim denials hit 11.8%, credentialing delays cost providers $50,000 or more, and NCQA now mandates monthly provider monitoring, healthcare practices need a partner who manages the full lifecycle. From CAQH profile setup and payer enrollment to clean claim submission, denial resolution, and ongoing compliance monitoring, every piece has to work together.

Pro-MedSole RCM delivers end-to-end medical billing and credentialing services for healthcare providers nationwide. Whether you’re opening a new practice, adding providers to an existing group, expanding into telehealth across multiple states, or simply tired of chasing payer applications and watching revenue slip through credentialing gaps, our team handles every step.

You got into healthcare to take care of patients. Let us take care of the billing and credentialing so you can do exactly that.
