The 120-Day Rule: Why Medical Groups Must Start Credentialing Before the Offer Ink Dries

By Dr. Rachel Vance, MD·August 18, 2026·7 min read

In healthcare, a physician’s salary begins on their contractual start date. Their billing, however, does not begin until the final commercial health plan executed contract clears the clearinghouse. In between sits an average delay of 60 to 180 days.

The Real Cost of Delayed Activation

According to the 2026 Medallion State of Payer Enrollment Report, 69% of US healthcare provider groups lose between $1,000 and $5,000 per clinician per day to credentialing lag. For a group hiring ten physicians a year, an average 90-day delay per doctor results in over $900,000 in unbilled deferred revenue.

How to Implement the 120-Day Cadence

Leading medical groups do not wait for orientation day to initiate CAQH ProView setup. By utilizing HRIS webhooks triggered upon signed offer letters, ClearPath Payer runs 10-point Primary Source Verification and dispatches PECOS and commercial health plan dossiers at T-120 days.

Key Takeaway:Starting credentialing 120 days prior to start date ensures that by day one, over 95% of commercial and Medicare enrollments are fully active, completely eliminating provider payroll waste.
