Arizona changed the rules for credentialing in 2026, and the change is good news for small practices. Since April 1, 2026, state-regulated health insurers have 60 days to finish credentialing, not 100, and they have to pay new clinicians back to the date their application was complete. Add AHCCCS, where every plan sets its own filing limit, and Arizona rewards practices that track dates carefully.
This guide is for therapy, counseling, psychiatric, and speech therapy practices billing commercial plans and AHCCCS in Arizona.
Credentialing: the 2026 law
SB 1291, signed in 2025 and in effect since April 1, 2026, rewrote Arizona's credentialing rules for health insurers:
- 7 days to acknowledge. The insurer must confirm it received the application and say whether it is complete. An incomplete notice must list every missing item.
- 60 days to conclude credentialing, and 30 days to load the provider into the billing system after the application is complete.
- Limited pauses. The insurer can stop the clock to ask for more information up to three times. If the provider doesn't answer within 30 days after the third request, the application can be treated as withdrawn.
- Retroactive payment. Once the contract is signed and the provider is approved, services delivered from the date of the complete-application notice are paid as in-network.
- Filing protection. A claim for that period submitted within one year of the service can't be denied only because it missed the contract's filing deadline.
- Patient disclosure. A clinician who isn't credentialed yet must give the patient a dated written notice with the billing provider's name, the estimated cost, and a statement that the provider isn't contracted, before treating at a network facility.
Every application also needs an email contact for the insurer to resolve problems. Use a shared credentialing inbox, not one person's address, so notices don't sit unread.
The complete-application notice is now the most important document in Arizona credentialing. It starts the 60-day clock and the retroactive payment window. Save it in the provider's file the day it arrives.
Claim payment and interest
Under A.R.S. 20-3102, as the Department of Insurance and Financial Institutions explained in Regulatory Bulletin 2025-01:
- Insurers have 30 days from receipt to adjudicate a clean claim, and 30 more days from adjudication to pay the approved amount.
- If a claim isn't clean, the insurer must ask for the missing information within 30 days, then adjudicate and pay within 30 days of getting it.
- Late payments owe interest at the legal rate of 10% a year from the date payment was due. A contract can set a different reasonable rate but can't waive interest.
- Payment disputes go to the insurer's own provider grievance process first. DIFI doesn't decide individual claims, but it can step in if an insurer ignores a grievance.
Prior authorization
Current Arizona law gives plans 5 days for urgent requests and 14 days for non-urgent requests, counted from when the plan has the information it needs. In 2026 the legislature considered shortening these to 72 hours and 7 calendar days starting in 2027; check whether that passed before relying on it.
For AHCCCS plans and Medicare Advantage, the federal interoperability rule already requires decisions within 7 calendar days for standard requests and 72 hours for expedited ones, starting in 2026.
AHCCCS: one program, many plans
AHCCCS is Arizona's Medicaid program. Most members are enrolled in AHCCCS Complete Care plans, which cover physical and behavioral health together, and members with a serious mental illness are served by plans that also act as the regional behavioral health authority. Providers register with AHCCCS and then contract and credential separately with each plan.
Filing limits are where AHCCCS billing goes wrong, because they differ:
| Initial claim | Correction or clean claim | |
|---|---|---|
| AHCCCS fee-for-service (billing manual) | 6 months from the date of service | 12 months from the date of service |
| Arizona Complete Health (provider manual) | Accepted as clean within 120 days of the service or eligibility posting | 365 days; 60 days after a recoupment |
Two details from the plan manuals matter. A rejected claim doesn't count as a timely submission, so a clearinghouse rejection you never fixed can cost you the claim. And a corrected claim needs frequency code 7 or 8 plus the original claim number, or it is treated as a new, late claim. Proof of timely filing has to be an EOB, a denial letter, or an EDI acceptance report; screenshots and spreadsheets don't count.
Licensing and telehealth
Counselors, social workers, marriage and family therapists, and addiction counselors are licensed by the Arizona Board of Behavioral Health Examiners. Arizona participates in the Counseling Compact and PSYPACT, but compact privileges don't replace payer credentialing: each plan still needs the clinician in its network before claims pay in-network.
An Arizona billing checklist
- Use a shared email on every credentialing application.
- Save the complete-application notice and calendar the 60-day mark.
- Track sessions seen while credentialing is pending, and bill them within a year once approved.
- Give the written disclosure to patients seen by a clinician who isn't credentialed yet.
- Write down each AHCCCS plan's filing limit. Use the shortest one (120 days) as your internal deadline.
- Fix clearinghouse rejections within two business days.
- Flag clean claims unpaid after 60 days, and check that interest was added when they are paid late.
- File payment disputes through the insurer's provider grievance process, in writing.
