Here is the most expensive credentialing mistake an independent practitioner can make: waiting until Month 2 or Month 3 to start the payer credentialing process. It happens constantly, and the reason is always the same - practitioners don't know how long credentialing actually takes until they're already behind.
The reality is this: from the day you submit a completed credentialing application to a commercial payer, you should expect 90 to 120 days before you are fully credentialed and able to bill under your own NPI. For Medicare, the window can be 60 to 90 days. For some state Medicaid programs, you may be waiting 120 to 150 days. If you submit in Month 3, you open without the ability to bill insurance. That is a revenue gap your practice may not be able to absorb in its first critical months.
"The 90-day credentialing clock starts when you submit - not when you decide you should probably get started."
CAQH: The Foundation You Build First
Before you can credential with any major commercial payer in the United States, you need a complete and attested CAQH ProView profile. CAQH (Council for Affordable Quality Healthcare) is the centralized database that most payers pull from when evaluating credentialing applications. An incomplete or outdated CAQH profile is one of the top reasons credentialing applications are delayed or rejected.
Your CAQH profile must include your individual NPI (Type 1), your license information, your malpractice coverage details, your work history for the past ten years, your education and training, and your DEA registration if applicable. You will also need your CAQH profile to be attested - meaning re-verified by you - every 120 days. If your attestation lapses while a credentialing application is pending, the application stalls.
CAQH ProView setup checklist
- Individual NPI (Type 1) - required before you can create a CAQH profile
- Current malpractice certificate with effective dates and coverage amounts
- DEA registration certificate (if prescribing)
- State license(s) - current, with expiration dates
- Board certifications if applicable (ANCC, NBCC, etc.)
- Complete work history - 10 years, with no unexplained gaps
- Education and training records - copies of diplomas and transcripts may be requested
- Attestation - must be completed and kept current every 120 days
NPI Type 2: Why Your Group NPI Must Come First
Most practitioners know they need a National Provider Identifier (NPI). What many don't realize is that there are two types, and the sequencing matters. Your Type 1 NPI is your individual provider identifier - you already have this from your employed career. Your Type 2 NPI is a group or organizational NPI assigned to your business entity.
You cannot apply for an NPI Type 2 before you have formed your business entity, because the Type 2 is tied to the legal name and EIN of your LLC or PLLC. And you cannot submit most payer credentialing applications as an independent practice without a Type 2 - because you need to bill under a group NPI, not just your individual NPI, to receive payment as a practice owner rather than as an individual provider.
The sequence is non-negotiable: file your entity, get your EIN, apply for your Type 2 NPI, complete CAQH, then submit to payers. Skipping a step doesn't accelerate the process - it restarts it.
Which Payers to Prioritize and Why
You cannot credential with every payer simultaneously, and even if you could, the administrative overhead wouldn't be worth it for payers who represent a small share of your patient population. The correct strategy is to prioritize by volume and urgency, then expand the panel over the first 12 months of practice.
For most PMHNPs, NPs, and therapists in independent practice, the priority order is: Medicare first, your state's Medicaid program second, then the top two to three commercial payers by market share in your region. In most U.S. markets, those commercial payers are UnitedHealthcare, BlueCross BlueShield (in one of its regional forms), and Aetna or Cigna depending on the state.
Therapists in particular should note that Medicaid is often the highest-volume payer for behavioral health outpatient services in many states - especially for practitioners targeting underserved populations. The Medicaid credentialing timeline is also among the longest, which makes starting in Month 1 even more critical for therapists planning to see Medicaid patients at launch.
| Payer | Typical Timeline | Application Method | Priority |
|---|---|---|---|
| Medicare (CMS) | 60–90 days | PECOS online portal | Highest - submit Week 1 |
| State Medicaid | 90–150 days | State-specific portal or paper | Highest - submit Week 1–2 |
| UnitedHealthcare | 90–120 days | UHC Provider Portal via CAQH | High - submit Week 2–3 |
| BlueCross BlueShield | 90–120 days | BCBS regional portal or CAQH | High - submit Week 2–3 |
| Aetna / CVS Health | 90–120 days | Availity / CAQH | High - submit Week 3–4 |
| Cigna / Evernorth | 90–120 days | Cigna Provider Portal / CAQH | Medium - submit Month 2 |
| Tricare | 60–90 days | Humana Military / WPS portal | Medium - if serving military |
Common Reasons for Delays - and How to Avoid Them
The majority of credentialing delays are caused by one of four things: incomplete applications, expired or mismatched documentation, outdated CAQH profiles, and lack of follow-up. None of these are inevitable. All of them are preventable.
Incomplete applications are the most common cause of delay. Payers will not contact you proactively if something is missing - they will simply hold the application. Build the habit of submitting complete packets with supporting documentation attached at the time of submission, not as a follow-up.
Lapsed CAQH attestation is the second most common cause. Set a calendar reminder to re-attest your CAQH profile every 90 days - not every 120, because you want a buffer. A lapsed profile pauses every pending application that depends on it simultaneously.
Mismatched information - your name spelled differently on your license versus your NPI versus your malpractice certificate - causes applications to stall while the payer requests clarification. Audit all documents for consistency before submitting anything.
How to follow up on credentialing applications
Create a tracking spreadsheet with every payer, the submission date, your application or reference number, the name of the provider relations representative if you reached one, and a follow-up date 30 days out. Call or email at the 30-day mark to confirm receipt and ask for a status update. Do the same at 60 days. Payers process applications faster when they know a practitioner is actively tracking.
What to Do While You Wait: The In-Network Gap Strategy
If your credentialing applications are pending when you open, you are not helpless - you are temporarily out-of-network. This is different from choosing to be a cash-pay practice. As an out-of-network provider, your patients can still often submit claims to their insurance for partial reimbursement depending on their plan's out-of-network benefits. You collect full payment from the patient at the time of service, and you provide a superbill - a detailed receipt with procedure codes and diagnosis codes - that the patient submits to their insurer.
This strategy works best for practitioners targeting patients with robust commercial insurance plans. It works less well for practitioners targeting Medicaid populations, which is one more reason therapists who plan to see Medicaid patients should prioritize Medicaid credentialing above everything else and start as early in Month 1 as physically possible.
The in-network gap window is also an excellent time to build a hybrid practice revenue model. A portion of your panel on cash pay, a portion on superbill, and the rest transitioning to insurance billing as your credentialing comes through - this staged approach is financially resilient and avoids the revenue cliff of waiting for full credentialing before seeing any patients at all.
"Out-of-network is not a failure state. It's a temporary billing status. The clock is already running if you started in Month 1."
The practitioners who open strongest are the ones who treated the 90-day window before launch as productive, not passive. They submitted credentialing applications in Week 1, built their CAQH profile before anything else, followed up at 30 and 60 days, and had a clear plan for what to do with patients who arrived before the panel opened. That preparation is what makes a clinical launch feel smooth rather than chaotic - and it starts on Day 1 of Month 1.
