Credentialing 101: Why It Matters and How to Avoid Costly Delays

If you've ever waited weeks (or months) to get paid for services you've already provided, there's a good chance credentialing was part of the holdup. For solo and independent providers, credentialing is one of those behind-the-scenes processes that doesn't get much attention — until it goes wrong.

Here's what you need to know.

What Is Credentialing, Exactly?

Credentialing is the process insurance companies use to verify that you're qualified to provide care and to approve you as an "in-network" provider for their plans. It involves submitting documentation about your education, training, licensure, malpractice history, and more — and it's required by every payer you bill, including Medicare and Medicaid.

A related piece is your CAQH profile — a centralized database many payers use to pull your credentialing information. If your CAQH profile is incomplete, outdated, or not re-attested on time, it can stall credentialing applications across multiple payers at once.

Why Credentialing Delays Are So Costly

Until you're credentialed with a payer, you typically can't bill that payer for your services — or you may be paid at a much lower out-of-network rate. For a new provider joining a practice, or a practice adding a new payer, this can mean weeks or months of unbilled (or underpaid) services.

Common causes of delays include:

•        Incomplete or outdated CAQH profiles

•        Missing documentation (licenses, certificates, malpractice insurance)

•        Applications submitted with errors that bounce back for correction

•        Re-credentialing deadlines that get missed

•        No one tracking the status of pending applications across payers

How to Avoid the Most Common Pitfalls

Start early. Credentialing can take anywhere from 60 to 120+ days depending on the payer. If you know a new provider is joining your practice, or you're planning to add a payer, start the process as soon as possible.

Keep your CAQH profile current. This should be reviewed and re-attested regularly — not just when a payer asks for it.

Track everything. Applications, expiration dates, re-credentialing cycles, and payer-specific requirements all need to be monitored consistently. A missed deadline can mean falling out of network entirely.

Follow up proactively. Payers don't always notify you when something is missing. Regular check-ins on application status can catch issues before they become delays.
