You did the degree. You did the supervised hours. You passed the exam, and your state put its name behind yours. Then you asked a commercial insurer to let you join its network, and the insurer said: wait. MGMA puts the standard credentialing timeline at 90 to 180 days from application to approval (December 2021). That is three to six months. For most of it, the plan pays you nothing.
Therapists call this getting paneled. I call it the credentialing tax. It is the unpaid season almost every insurance-based practice pays before the first claim goes out. If you run a private practice in New York, New Jersey, or Connecticut, this one is for you. Here is what the tax is, what it really costs, which states finally put a clock on it, and how to shrink your own wait.
What is credentialing, and why does it take so long?
Credentialing is a background check. The insurer verifies your license, your degree, your work history, and your malpractice coverage. Fair enough. Clients deserve to know their therapist is real.
Most commercial plans pull that information from CAQH. CAQH is one big shared online profile that most insurers read instead of asking you separately. You fill it out once. Every plan you apply to then checks the same file.
The odd part is this. Your state already checked all of it when it licensed you. The insurer checks again anyway, on its own schedule. Per MGMA, that schedule runs 90 to 180 days (December 2021).
The application itself is not small, either. Expect the CAQH profile, the plan's own forms, a W-9, proof of malpractice coverage, and copies of your license and diploma. Miss one page and the file sits. Nobody calls to tell you.
What happens while you wait? You are out-of-network with that plan. If a plan member wants to see you, they pay out of pocket, or you hand them a superbill and hope. A superbill is a receipt the client submits to their plan for partial repayment. Either way, the network they pay premiums for does not include you yet.
Why so slow? In most states, no law puts a hard clock on a commercial insurer's credentialing decision. The insurer sets its own pace. That is exactly why the two state laws below counted as news.
What does the unpaid wait actually cost?
Credentialing-vendor blogs love big dollar figures here. Losses per day, losses per provider, per year. We went looking for the sources behind those numbers. They trace back to other vendor blogs, so we are not printing them.
The honest cost is your own math, and it takes one minute. Take your session rate. Multiply it by the sessions per week you would bill to that plan. Multiply that by 13 to 26 weeks, which is the 90-to-180-day range. That number is your personal credentialing tax. It is also the number to bring to any decision about joining a panel.
Want a plain example? Say your rate is $150, and ten sessions a week would run through the new plan. A 120-day wait is about 17 weeks. That is $25,500 in sessions the plan never paid for. Swap in your own numbers. The shape stays the same. And that assumes the wait ends on schedule.
Now the part that stings. After the unpaid wait, the panel pays behavioral health less than it pays everyone else. An RTI International study of claims covering more than 22 million commercially insured people found in-network pay averaged 22% higher for medical and surgical clinicians than for behavioral health clinicians (April 2024). Same plan, same premiums, lower rate for the clinician treating the mind. We broke that gap down in Why Commercial Insurers Pay Therapists So Little.
Many therapists run these numbers and walk away. The APA's 2024 Practitioner Pulse Survey of 853 licensed psychologists found that 34% are not in-network with any insurance (December 2024). Among the 374 who never joined, stopped, or dropped a panel, 82% cited low reimbursement, 62% cited administrative burdens like preauthorization, and 50% cited payment reliability. Read those three numbers again. None of them are about clinical work. All of them are about the machinery around it.
Clients feel the thin network too. The same RTI study found commercially insured patients went out-of-network 3.5 times more often for behavioral health care than for medical or surgical care, and 10.6 times more often to see a psychologist (April 2024). When joining costs months of unpaid work, fewer clinicians join. The people who pay for that are sitting on waitlists.
Which states are putting a clock on insurers?
Two so far, and both moved in 2025.
California. AB 1041, signed October 11, 2025, requires every commercial health plan and insurer to make a credentialing decision within 90 days of a completed application. If the insurer misses the deadline, you get provisional approval for 120 days. Provisional means approved for now, while the plan finishes its homework. The law also forces plans to use the standard CAQH form. California law already required mental health and substance use providers to be credentialed within 60 days.
Arizona. SB 1291, signed April 2025 and effective April 1, 2026, cuts the credentialing window from the old 100-day standard to 60 calendar days, plus 30 calendar days to load you into the billing system. Then it goes one better. Providers can collect in-network payment for care given from the day the insurer confirms the application is complete. That closes the unpaid gap itself, not just the wait.
Notice the phrase both laws lean on: a completed application. The clock starts when the file is complete, and the insurer decides what complete means. That makes the completion date the battleground. The checklist below is built around winning it.
If you practice in New York, New Jersey, or Connecticut, neither law covers you. Keep both handy anyway. Two states have now said, in law, that a 90-plus-day wait is a choice insurers make. It is not a law of nature. Remember that the next time a provider-relations rep tells you the timeline "is what it is."
If more states follow, it will be because clinicians kept receipts and showed up with them. Your follow-up emails are not just for you. They are the record the next bill gets built on.
How do you shrink your own wait?
You cannot make an insurer move fast. You can stop handing it excuses, and you can build a paper trail that pays off later. Here is the working checklist we would give a colleague:
1. Build your CAQH profile before you apply anywhere. Complete every section and upload every document. Most commercial plans pull from this one profile, and California now requires the CAQH form by law. 2. Start six months before you need the income. The MGMA range is 90 to 180 days (December 2021). Plan for the far end. Be pleasantly surprised by the near end. 3. Send complete applications. A missing document hands the plan a reason to pause your file. Check everything twice before you hit submit. 4. Get the "complete" date in writing. The new state laws count from a completed application. Ask the plan to confirm, in writing, the date your file was complete. 5. Follow up every two weeks, in writing. Email beats phone. A dated paper trail is leverage if your file stalls. 6. Ask whether the plan pays for the waiting period. Arizona now requires in-network payment from the confirmed-complete date. Elsewhere the answer varies by plan. You lose nothing by asking in writing. 7. Run the worth-it math before you apply. Your rate, the 22% gap, the wait. Our post on the real income ceiling of insurance work walks through that decision. 8. Bridge the gap on purpose. Some clinicians hold a few cash-pay slots or short-term contract work while panels process. If that is you, the therapist side-gig economy covers the options with clear eyes. 9. Set a repeating reminder for day 100. For the clock in the next section.
The tax never ends: the 120-day re-attestation clock
Getting paneled once does not finish the job. CAQH's provider user guide requires you to re-attest your entire profile every 120 days, or every 180 days in Illinois (current CAQH documentation, accessed July 2026). Re-attest means log in and confirm your information is still true.
Miss the window and your profile flips to "Expired." Payers can no longer pull it for credentialing or re-credentialing. So four times a year, forever, the system asks you to swear you still exist. Small clock, real teeth.
The re-attestation itself is quick when your records are current. It only hurts when it ambushes you. Put the day-100 reminder on your calendar next to your license renewal, and it stays a chore instead of a crisis.
Guarding your hours while the clock runs
The credentialing tax takes money. It also takes something scarcer, which is your hours. Application forms, portal logins, follow-up emails, re-attestation windows. All of it lands on top of a full caseload, your notes, and a life. We have written about how documentation load quietly burns therapists out. Credentialing is the same weight arriving from a different direction, and it drains the same pool of energy your clients need.
So guard the clinical core while the clock runs. Your clients get you for about 4 sessions a month. The other 26 days are where the work either sticks or slips. That between-sessions space is what VibeCheck is for, built by a clinician who fills out these same forms. It will not credential you. It helps the clinical work carry further while the system makes you wait. Curious? Take a look, or book a call.
FAQ
How long does insurance credentialing take for therapists?
Ninety to 180 days from application to approval, per MGMA (December 2021). Some states now cap it. California's AB 1041 requires a decision within 90 days of a completed application (October 2025). Arizona's SB 1291 allows 60 days plus 30 to load billing, effective April 1, 2026.
Can I bill an insurance plan while credentialing is pending?
In most cases, no. Until approval, the plan treats you as out-of-network. Arizona's SB 1291 now requires in-network payment for care given from the date the insurer confirms your application is complete (April 2025). Elsewhere, ask each plan in writing before you count on anything.
What is CAQH, and what happens if I forget to re-attest?
CAQH is the shared online profile most commercial insurers use to credential you. Per CAQH's user guide, you must re-attest every 120 days, or 180 in Illinois. Miss it and your profile flips to "Expired," and payers cannot pull it for credentialing or re-credentialing.
Is joining an insurance panel worth months of unpaid waiting?
Sometimes. Run your own math first. RTI International found in-network pay averaged 22% higher for medical and surgical clinicians than for behavioral health (April 2024). The APA found 34% of psychologists take no insurance at all (December 2024). The wait belongs in that math too.
