How Long Does Credentialing Take? Timelines by Payer Type, and How to Avoid Delays

Credentialing usually takes 30 to 60 days for Medicare, 30 to 90 days for state Medicaid, and 60 to 120 days for most commercial insurance plans, counted from a complete application. Behavioral health networks run by a separate company often take 90 to 150 days, and psychiatric nurse practitioners often need 90 to 180 days end to end. Start 90 to 120 days before you want to see insured patients, and do not bill as in-network until you have a signed contract and an effective date in writing.

Most credentialing delays have nothing to do with the payer being slow. They come from incomplete applications, mismatched details, and nobody following up. Knowing the typical timeline, and what resets the clock, lets you plan your start date and cash flow.

Typical timelines by payer type

Payer type	Typical time from a complete application	Notes
Medicare (PECOS or CMS-855)	30 to 60 days	Limited retroactive billing, generally up to 30 days before the filing date
State Medicaid	30 to 90 days	Varies by state; managed care plans add a contracting step. In Georgia, the state’s centralized credentialing aims for a decision within 45 days; see our Georgia Medicaid guide
Commercial plans (Aetna, Cigna, UnitedHealthcare, Blue Cross plans)	60 to 120 days	Closed panels can mean a denial after the wait
Behavioral health networks (for example Optum, Carelon, Evernorth)	90 to 150 days	Often a separate application from the medical plan
PMHNPs, end to end	90 to 180 days	Collaborative agreements, DEA and multi-state rules add time

These are typical ranges, not promises. Each payer’s current processing time can change with its workload.

Credentialing vs contracting

Two separate steps happen, often one after the other:

1. Credentialing: the payer verifies your license, education, malpractice coverage, work history and sanctions.
2. Contracting: the payer offers a network agreement with rates and an effective date.

You are in network only after both are done. Many practices lose money by seeing patients after credentialing is approved but before the contract’s effective date.

What slows credentialing down

Delay	How to avoid it
CAQH profile incomplete, not attested or not shared with the payer	Complete every section, upload current documents, authorize the payer, and re-attest every 120 days (CAQH guide)
NPI, taxonomy or address mismatch between NPPES, CAQH and the application	Make all three match before you apply
Missing or expired documents	Check malpractice, license, DEA and board certificates before you start
Closed panel	Ask about network status first; apply where access is open or make a case for need
Wrong application path	Behavioral health networks often need their own application
No follow-up	Call or check the portal every one to two weeks and log each contact

Planning your start date

• New practice or new clinician: start 90 to 120 days before the first insured appointment.
• PMHNPs and multi-state telehealth: start 120 days or more ahead.
• Switching from a platform such as Headway or Alma: start credentialing well before you leave; see leaving Headway, Alma, Grow or Rula.
• Keep a private-pay or out-of-network option ready for the gap.

After you are approved

• Get the effective date in writing and load it into your EHR.
• Set up claims, ERA and EFT for each payer.
• Track recredentialing: commercial plans usually every three years, Medicare revalidation every five years, and CAQH re-attestation every 120 days.

This guide is general information. Payer processes and timelines change, so confirm current requirements with each payer.
