Credentialing is a revenue problem that looks like paperwork

A practice hires a new physician. The contract is signed, the room is ready and the schedule is filling. Then billing asks whether the provider is enrolled with the practice's commercial plans, and the answer is "we sent the applications last week." For the next few months, that physician sees patients the practice may not be able to bill for.

Credentialing and enrollment are two steps

People use the words interchangeably, but they are separate. Credentialing verifies that a provider is qualified: licenses, board certification, education, work history and malpractice history. Payer enrollment is the contract step that lets that provider bill a specific plan as in-network. A provider can be fully credentialed and still not enrolled with the plans your patients carry.

How long it takes

Timelines vary by plan and state, and industry estimates commonly put payer enrollment at 60 to 120 days. In an MGMA Stat poll from November 2025, 65% of medical groups said their provider files were on time, while 32% reported a backlog, a delay at their credentialing verification organization, or work slipping into the next quarter. The delays traced mostly to payer enrollment, slow reference and board verifications, and thin staffing.

The maintenance nobody schedules

• CAQH ProView profiles must be re-attested every 120 days. A lapsed attestation can stall enrollment with plans that rely on CAQH.
• Medicare enrollment must be revalidated, generally every five years. CMS posts revalidation due dates in advance.
• Most commercial plans recredential providers about every three years.
• A new location, tax ID or group affiliation often needs its own update with each plan.
