Summary
Effective September 1, 2026, claims submitted by fee-for-service providers that include a referring, ordering, attending or prescribing provider who is not registered with AHCCCS will be denied, and those providers must register or be identified as exception non-registerable providers. Group behavioral health services must have the HQ modifier appended to the service code, and omitting it results in inaccurate billing and may directly affect reimbursement. Intensive Outpatient Program prior authorization requests must use Event Type OP until AHCCCS adds IOP as a selectable event type.

What to do
Action · 21 steps
01Already effective September 1, 2026: Billing team: before submitting a fee-for-service claim, confirm that each referring, ordering, attending and prescribing provider on the claim is registered with AHCCCS.
02Claims that include a provider in those roles who is not registered will be denied.
03If a provider who refers, orders or acts as an attending provider for AHCCCS members is not registered, begin the registration or exception provider designation process through AHCCCS Provider Enrollment.
04A streamlined application is available for providers who have an NPI from NPPES, are already fully enrolled in Medicare or another state's Medicaid program, and do not intend to bill AHCCCS for services.
05Check current applicability before acting on this date.
06Ongoing: Billing team: for intensive outpatient program (IOP) prior authorization requests, submit using Event Type OP until AHCCCS adds IOP as a selectable event type.
07DFSM will send an email notification when the IOP option becomes available.
08Ongoing: Billing team: for behavioral health services rendered in a group setting, including timed and per diem service codes such as H0004, H2038, H2014 and H2018, append the HQ modifier to the service code, because behavioral health service delivered to multiple clients simultaneously requires it.
09Group progress notes must document the exact service duration, diagnosis, the member's response to services, and the type and description of services provided; signatures must include credentials; and documentation cloning is strictly prohibited.
10Refer to the Behavioral Health B2 Matrix and the AHCCCS Covered Behavioral Health Services Guide for billing criteria.
11Ongoing: Billing team: for dental claims that use the JO qualifier, report the tooth number in two digits, for example 01 for tooth 1 and 02 for tooth 2, because a tooth number not listed in two-digit format can result in the claim being returned or denied.
12Ongoing: Billing team: submit the initial claim within 6 months of the date of service.
13Confirm that any replacement or correction claim is submitted within 12 months of the date of service, unless retro-eligibility applies.
14A replacement claim for a date of service past 12 months results in automatic recoupment of any payments and the identified claim is placed in Void status.
15Ongoing: Billing team: for errors that resulted from a direct claim submission, submit a replacement or correction claim that carries the previously entered fields with the correct information, because AHCCCS cannot edit or change the details the provider entered.
16If you are uncertain which fields to use for Other (OTH) or Medicare amounts, leave those fields blank and submit a copy of the Explanation of Benefits (EOB).
17Ongoing: Billing team: for claim denials under reason code L243.1, the source says AHCCCS identified a system error that may have caused claims to deny in error and that AHCCCS will reprocess the affected claims.
18Providers do not need to resubmit affected claims and do not need to contact Provider Services about this denial reason code.
19Ongoing: Billing team: submit tickets through the AHCCCS Solutions Center, which launched May 4, 2026 and replaced ServiceDesk.
20Ongoing: Billing team: refer to the AHCCCS Medical Coding Resource Guide for place of service, modifiers, procedure codes, diagnosis codes and coding rules.
21Ongoing: Each user must have their own AHCCCS Online Provider Portal account, because sharing usernames and passwords is prohibited, and the provider is responsible for all activity under its account.
