Payer Enrollment Timelines: What to Expect by Payer Type

This article is for practice owners, providers, and anyone managing the administrative side of a practice launch or provider onboarding. It's especially useful for setting realistic expectations around cash flow timing.

The timelines below are estimates based on typical processing times. Actual timelines can be shorter or longer depending on:

• Application completeness — missing documents or outdated information are the most common cause of delays
• Payer volume — some payers process applications faster than others, and backlogs can vary by season
• State-specific requirements — particularly relevant for Medicaid
• CAQH attestation status — if your CAQH profile is lapsed or incomplete, payers cannot pull your information and processing stalls

The golden rule: Start credentialing 90–120 days before your anticipated first patient date. This buffer gives you the best chance of having active coverage in place before you begin seeing patients.

Commercial Payers

Examples: UnitedHealthcare, Aetna, Blue Cross Blue Shield, Cigna, Humana

Typical timeline: 60–120 days

Commercial payers are the most variable group. Each payer has its own application process, internal review team, and credentialing committee schedule — some meet monthly, which means a near-miss on a submission deadline can add 30 days to your timeline on its own.

Most commercial payers rely on your CAQH ProView profile to pull supporting documentation, so keeping that profile complete and attested is especially important here.

Medicare

Administered by CMS through PECOS

Typical timeline: 30–60 days

Medicare enrollment is managed through the PECOS system and is generally one of the faster processes — but it requires Duet to have surrogate access to your CMS I&A account before we can submit anything on your behalf. Delays in granting that access are the most common reason Medicare enrollment falls behind schedule.

Once submitted, Medicare applications are processed by your MAC (Medicare Administrative Contractor), which varies by region. Processing times can fluctuate based on MAC workload.

See article 2.2 for steps on setting up Medicare surrogate access.

Medicaid

Administered at the state level

Typical timeline: 60–180+ days (highly variable by state)

Medicaid is state-administered, which means every state has its own application portal, requirements, and processing times. This is the most unpredictable category — and often the longest.

Duet currently supports Medicaid enrollment in the following states:

• Arizona (AZ)
• Colorado (CO)
• Connecticut (CT)
• District of Columbia (DC)
• Florida (FL)
• Georgia (GA)
• Illinois (IL)
• Maryland (MD)
• Massachusetts (MA)
• Minnesota (MN)
• Mississippi (MS)
• New Hampshire (NH)
• New Mexico (NM)
• New York (NY)
• Ohio (OH)
• Oklahoma (OK)
• Oregon (OR)
• South Dakota (SD)
• Texas (TX)
• Virginia (VA)

Important: Some states require additional steps such as state-specific provider agreements, managed care organization (MCO) enrollments, or re-enrollment after a gap in participation. Duet will flag any state-specific requirements that apply to your situation.

CAQH-Dependent Payers

Timeline: Dependent on CAQH profile status

Many payers — particularly commercial ones — rely entirely on your CAQH ProView profile rather than a separate application. For these payers, your timeline is directly tied to whether your CAQH profile is complete, accurate, and currently attested.

If your CAQH profile is in good shape when Duet begins your credentialing, these payers can often move faster than others. If it's incomplete or lapsed, they'll be among the slowest.

Can multiple payer enrollments happen at the same time?

Yes — Duet submits applications to multiple payers simultaneously where possible. You don't have to wait for one to finish before another begins.

What happens if my credentialing takes longer than expected?

Duet will keep you updated on status and flag any blockers. In the meantime, there may be options like billing under a supervising provider or holding claims for retroactive billing. See article 2.4 for more detail.

Does my Medicare enrollment carry over if I move to a new practice or TIN?

No. Medicare enrollment is tied to a specific Tax ID (TIN) and practice location. Any change in TIN requires a new enrollment.

What if I'm not sure which payers to credential with?

Duet can help you identify which payers make sense based on your patient population and practice location. Reach out to your account manager to discuss.
