Why New US Physicians Wait 90+ Days to Get Paid

A new physician joins a practice. Patients are scheduled. Care is delivered from day one. And then the practice discovers something frustrating: none of those claims can actually be billed yet, because the provider isn't credentialed with the payers those patients are covered by.

For independent and small US practices, this isn't a rare hiccup. It's one of the most common, and most expensive, blind spots in bringing on a new provider.

Credentialing Isn't a Formality. It's a Prerequisite to Getting Paid

Before a physician can bill Medicare, Medicaid, or most commercial payers, they need to be formally credentialed and enrolled with each one individually. Until that's complete, services rendered by that provider generally cannot be reimbursed, no matter how clean the documentation or coding is.

That means the 60, 90, or sometimes 120+ days this process takes aren't just an administrative delay. They're a direct hold on revenue for every patient that provider sees during that window.

Where the Delay Actually Comes From

CAQH profile issues. Most commercial payers pull credentialing data from a CAQH profile, and that profile requires periodic re attestation. An expired attestation, a missing document, or an incomplete section can silently stall an application that otherwise looks ready to go.

PECOS and Medicare enrollment complexity. Medicare enrollment runs through its own system, PECOS, with its own data requirements and validation steps. A mismatch between what's submitted there and what payers expect elsewhere in the process is a common, quiet source of delay.

Payer specific backlogs. Each commercial payer processes credentialing applications on its own timeline, and that timeline can shift based on internal volume, staffing, or seasonal application spikes, factors entirely outside a practice's control.

Incomplete or inconsistent provider data. NPI details, license numbers, malpractice history, and practice location information all need to match precisely across every system a provider is enrolled in. Even small inconsistencies can trigger additional review or a request for clarification, restarting parts of the timeline.

Re verification triggers. Certain changes, like a new practice location or a lapse in continuous enrollment, can require payers to re verify information that was previously approved, adding time even for physicians who aren't credentialing from scratch.

Why Practices Don't See This Coming Until It's Already a Problem

Most practices only think about credentialing once, when a new provider is hired, without realizing it needs to be tracked, followed up on, and managed proactively with each individual payer until every enrollment is fully active. By the time a claim gets denied for "provider not enrolled," the practice is usually already weeks or months into lost revenue, without a clear picture of which payers are still pending and why.

The Real Cost Isn't Just the Wait. It's the Revenue Sitting Behind It.

Every day a provider sees patients while credentialing is still pending is a day of services that either can't be billed yet, or that will need to be billed retroactively once enrollment clears, if the payer allows retroactive billing at all. For a small or independent practice adding even one new provider, that gap can represent a significant amount of temporarily, or permanently, unrecoverable revenue.

Is Your Practice Tracking This the Right Way?

If your practice has ever had a new provider seeing patients before every payer enrollment was fully confirmed, it's worth understanding exactly where that revenue currently stands, and whether any of it is still recoverable.
