AHCCCS DFSM Claims Clues - September 2026
Effective date
Not stated in the notice
Identified
Sep 29, 2026
Summary
AHCCCS fee-for-service claims with attachments must have the initial claim submitted first, because documentation sent before the claim cannot be matched and will cause delays and denials. The Attachment Control Number (PWK) must be created during the initial claim submission, and all identifiers must match exactly between the claim and the attachment. Behavioral health services delivered to a group require the HQ modifier, dental procedures need two-digit tooth numbers when using JO, and the initial claim must be received within six months of the date of service.

What to do
Action · 18 steps
01Billing team: For attachments, submit the initial claim first and never send documentation before it.
02Create the Attachment Control Number (PWK) during the initial claim submission, whether through the AHCCCS Online Provider Portal, billing software or a clearing house, and enter that exact PWK in the Attachment Control Number (PWK) field when uploading the documentation in the EDI Solutions portal.
03If no PWK was created, the AHCCCS 12-digit claim number can be used to attach the document.
04Verify that all identifiers match exactly between the claim and the attachment.
05Billing team: For group behavioral health services, append the HQ modifier to the applicable service code, such as H0004, H2038, H2014 or H2018, whenever the service is rendered in a group setting rather than one-to-one.
06Failing to append HQ when required results in inaccurate billing and may directly affect reimbursement.
07Group progress notes must record exact service duration, diagnosis, the member's response, and the type and description of services, and documentation cloning is strictly prohibited.
08Billing team: For dental claims using JO, enter tooth numbers in two digits, for example 01 for tooth 1.
09A tooth number not in two-digit format can result in return of the claim to the provider or denial.
10Billing team: The initial claim must be received within six months of the date of service.
11For a correction or replacement claim, confirm it is still within 12 months of the date of service unless retro-eligibility applies.
12If the date of service is past the 12-month period and a replacement claim is submitted, AHCCCS states that any payments issued will be automatically recouped and the identified claim will be placed in Void status.
13Submit the replacement claim with all previously entered fields corrected.
14If unsure which fields hold Other (OTH) or Medicare amounts, leave those fields blank and submit a copy of the Explanation of Benefits (EOB).
15AHCCCS cannot edit or change details the provider entered.
16Providers: Skilled nursing facility claims that denied with remark code H189.1 do not need to be resubmitted, because AHCCCS will reprocess all affected claims.
17Providers: Each user must have their own AHCCCS Online Provider Portal account, because sharing usernames and passwords is prohibited.
18Providers: Continue submitting Intensive Outpatient Program (IOP) prior authorization requests using Event Type OP until AHCCCS adds IOP as a selectable event type; DFSM will send an email notification when that option is available.
