5 Common Misconceptions About Medical Credentialing That Cost Practices Money

Most of the credentialing problems we see at practices aren't caused by bad intentions or negligence. They're caused by misunderstanding how credentialing actually works — what it is, how long it takes, what can go wrong, and why it has to be managed continuously.

These five misconceptions are the ones that consistently cost practices the most money.

Misconception 1: Credentialing and Licensing Are the Same Thing

This is the most fundamental confusion in healthcare credentialing, and it leads practices to believe a provider is ready to bill when they aren't.

A medical license is a legal authorization from a state medical board granting a provider permission to practice medicine in that state. It says: this person met the state's requirements to be a physician (or NP, PA, etc.). Without it, a provider cannot legally see patients.

Credentialing with a payer is a separate process entirely. It's how an insurance company verifies that a provider meets their specific standards to participate in their network. Until a provider is credentialed with a payer, that payer will not reimburse claims submitted under that provider's NPI — regardless of whether the provider is fully licensed and legally practicing.

A provider can be licensed to practice in California and completely unable to bill Anthem, Blue Shield, Aetna, UnitedHealthcare, Medicare, and Medi-Cal simultaneously — because they haven't been credentialed with any of them yet.

This matters because practices often hire a new provider, confirm their license is active, and start scheduling patients — without starting the credentialing process. When the claims come in, they all get denied. The revenue from those patients during the uncredentialed period is typically unrecoverable.

The fix: Start credentialing applications 90–120 days before a new provider sees their first insured patient.

Misconception 2: Credentialing Only Needs to Happen Once

Credentialing is not a one-time event. It is an ongoing, cyclical process with real consequences if it lapses.

Every commercial payer requires re-credentialing on a schedule — typically every 2 to 3 years. If re-credentialing is not completed on time, the payer can suspend the provider from their network. That means claims submitted under that provider number get denied until the re-credentialing is complete.

Beyond re-credentialing cycles, payers also require notification within 30–90 days (depending on the payer) of:

• A change in practice location or address
• A change in malpractice carrier or coverage limits
• License renewal (they want to see the updated certificate)
• A change in group ownership or Tax ID
• Hospital privilege changes
• Any adverse actions — sanctions, disciplinary actions, malpractice judgments

Missing a re-credentialing deadline or failing to notify payers of changes doesn't produce an immediate, obvious error. It produces a quiet suspension that you often don't discover until claims start bouncing.

The fix: Track every provider's re-credentialing deadlines, document expiration dates for all credentials, and set calendar reminders at 120, 90, and 60 days before each deadline.

Misconception 3: CAQH Takes Care of Credentialing

CAQH ProView is a centralized database where providers store their credentialing information. Most commercial payers pull from CAQH rather than requiring you to resubmit the same documents to each payer individually. It saves enormous time and is genuinely valuable.

But CAQH is not credentialing. It is a data storage and retrieval system. Having a complete CAQH profile does not mean you are credentialed with any payer. It means payers have a place to pull your information from when they process your credentialing application.

The credentialing applications still need to be submitted to each payer individually. Each payer still has its own review process, its own timeline, and its own credentialing committee. CAQH just removes the document-collection step from each of those applications.

There's a second CAQH misconception worth addressing: many providers complete their CAQH profile once and assume it stays active. It doesn't. CAQH requires re-attestation every 120 days. If your attestation lapses, payers cannot pull your data — and your credentialing or re-credentialing applications stall silently, with no notification sent to you.

The fix: Set a calendar reminder every 90 days to log in and re-attest your CAQH profile. Check that all information is current before attesting — outdated malpractice certificates or expired licenses will generate payer rejections even if the attestation itself is current.

Misconception 4: Credentialing Only Applies to Physicians

Any provider who bills under their own National Provider Identifier (NPI) needs to be credentialed with each payer they bill. That includes:

• Physicians (MD, DO)
• Nurse Practitioners (NP)
• Physician Assistants (PA)
• Licensed Clinical Social Workers (LCSW)
• Marriage and Family Therapists (MFT)
• Psychologists
• Physical Therapists
• Occupational Therapists
• Chiropractors
• Certified Nurse Midwives

Practices that employ mid-level providers often overlook credentialing them separately — especially when they're billing under a supervising physician's NPI during a provisional period. The moment those providers begin billing under their own NPI, their individual credentialing with each payer is required.

Additionally, facility credentialing — credentialing the practice entity under its NPI Type 2 and Tax ID — is separate from provider credentialing. Even if every provider in a group is individually credentialed, the group itself may need to be enrolled for claims billed under the group NPI to be reimbursed.

The fix: When any new provider joins the practice, initiate their credentialing applications with all relevant payers immediately — regardless of their provider type.

Misconception 5: Credentialing Delays Are Inevitable and Can't Be Shortened

The industry average for commercial payer credentialing is 60–120 days. Practices that manage their own credentialing often see it take longer. This leads to the assumption that nothing can be done to speed the process.

That's partially true — payer processing timelines are outside your control. But the majority of credentialing delays are caused by problems on the submission side, not the payer's side:

• Incomplete applications (missing documents, unsigned forms)
• Expired or lapsing CAQH attestations discovered mid-process
• Malpractice history gaps that require explanation letters
• Wrong Tax ID or NPI on the application
• Missing hospital privileges documentation
• Failure to follow up with payers proactively

A credentialing team that submits a complete, error-free application on day one — and follows up with each payer on a set schedule every 2–3 weeks — consistently achieves faster timelines than practices that submit when ready and wait.

The fix: Submit the most complete application possible the first time. Nothing extends credentialing timelines more reliably than a back-and-forth of missing document requests with the payer's credentialing department.

The Common Thread

All five of these misconceptions share a root cause: credentialing is treated as a one-time administrative task rather than an ongoing revenue-critical function. The practices with the smoothest credentialing outcomes are the ones that manage it proactively, track deadlines systematically, and treat it with the same seriousness as their billing operations.
