How long does Medicare credentialing take?

Medicare PECOS enrollment typically takes 45–90 days from clean submission to PTAN issuance. ProEnrollment averages 62 days through pre-submission audit and weekly MAC follow-up.

What payer takes the longest to credential with?

BCBS state plans typically take the longest = 60–120 days depending on the state plan. Some BCBS plans have regional variations. ProEnrollment submits to all payers simultaneously to minimize total timeline.

How Long Does Payor Credentialing Take?

Credentialing Timelines by Payer (2025–2026)

Payor credentialing timelines vary significantly by payer and completeness of the application. Here are realistic timelines from ProEnrollment's managed credentialing data across 500+ credentialed providers.

Payer	Typical Timeline	ProEnrollment Average
Medicare PECOS	45–90 days	62 days
Aetna	55–90 days	68 days
UnitedHealthcare	60–95 days	72 days
BCBS (state plans)	60–120 days	78 days
Cigna	45–85 days	64 days
Humana	60–90 days	71 days
Medicaid (state)	30–90 days	55 days

What Affects Credentialing Timeline?

The biggest factors: (1) CAQH completeness — incomplete profiles cause immediate deficiencies adding 2–4 weeks; (2) follow-up frequency — weekly follow-up vs monthly adds 30–60 days; (3) simultaneous vs sequential submission — simultaneous submission compresses total timeline to longest single payer.

What Actually Drives Your Timeline

Three factors control credentialing speed more than payer choice: CAQH readiness (an incomplete or expired profile adds 2–4 weeks before review even starts), application completeness (every deficiency cycle adds 2–8 weeks because files return to queue), and follow-up cadence (applications with weekly contact close 30–60 days faster than fire-and-forget submissions — files that get asked about get worked).

Realistic Planning Numbers

Plan your start date against these ranges: Medicare PECOS 45–90 days, Aetna 55–90, UnitedHealthcare 60–95, BCBS plans 60–120 (state-dependent), Cigna 45–85, Humana 60–90, state Medicaid 30–90, MBHOs (Optum, Evernorth, Magellan) 45–90. With simultaneous submission your total timeline equals your slowest payer, not the sum — which is why sequential DIY credentialing takes a year and managed simultaneous credentialing takes a quarter.
