The Real Credentialing Timeline

The number one question I get asked about credentialing is "How long does it take?"

Hiring a new clinician feels like growth until they cannot bill insurance for three months. Most practice owners underestimate credentialing timelines because payer enrollment is opaque, inconsistent, and rarely explained clearly.

Payer Timeline Estimates

The following table outlines typical ranges by payer type. Note that "Effective Dates" are often assigned after approval, not at the time of submission.

Payer Type	Typical Range	Critical Note
BCBS	60–90 Days	Group participation does not automatically link a new provider.
Aetna	90–120 Days	Entirely online, often faster than 90 days.
UHC / Optum	90–120+ Days	Behavioral health is often processed separately via Optum.
Cigna	60–120 Days	Highly region-dependent. Panel closures are common.
Medicare	45–90 Days	Requires PECOS submission and PTAN issuance.
Medicaid	60–120+ Days	State enrollment does not equal MCO enrollment (Molina, etc.).

Common Administrative Roadblocks

Approval from a payer does not equal operational readiness. Use this checklist to track the "hidden" steps that follow a credentialing approval.

Category	Requirements for Billing
Data Integrity	CAQH Attestation, NPI Registry Accuracy, Malpractice Mismatch Checks
Government	PECOS Reassignment, PTAN Issuance, Fingerprinting, Site Visits
Internal Ops	EMR Configuration, Clearinghouse Linkage, Fee Schedule Verification
Facility	REMS Program Participation, Facility Enrollment Alignment

The CAQH Misconception

CAQH is a data repository only. It is a vital tool, but it does not perform the following actions:

• Approve panel participation

• Assign effective dates

• Execute contracts

• Confirm reimbursement rates

• Link providers to groups

A Practical Timeline Rule

If you want a clinician billing by June 1, use the following submission deadlines:

• Medicaid: Start immediately (January or earlier).

• Commercial Plans: Submit by February or early March.

• Medicare: Submit no later than March.

If you are still deciding whether to build an insurance-based practice or start private pay, begin with my Private Practice Startup Guide.

Another early step when starting a practice is choosing the correct legal structure. Depending on your state and profession, you may need an LLC, PLLC, or S-Corp election.

Growth Requires Enrollment Infrastructure

Credentialing is not a one-time task. It is ongoing infrastructure that supports your revenue and your ability to grow.

Recredentialing, Medicare revalidations, and roster maintenance need to be actively managed. When they are not, issues show up as payment delays, participation gaps, and avoidable disruptions.

If you are hiring, expanding panels, or unsure where your providers stand, I am currently booking enrollment consults.
