What Providers Must Do
Submit prior authorization before providing Arizona Medicaid IOP services
Prior authorization is required before delivering IOP services for adult Arizona Medicaid/AHCCCS members for mental health (S9480) and substance use disorder (H0015) for dates of service on or after June 15, 2026. Submit requests online via the UnitedHealthcare Provider Portal (do not use Optum Provider Express) or by phone. Members already enrolled before June 15, 2026 are automatically authorized to complete treatment without new requests.
- Primary submission channel: UnitedHealthcare Provider Portal (UHCprovider.com) — sign in with One Healthcare ID, navigate to Prior Authorizations & Notifications, and create a new request.
- Do not submit via Optum Provider Express (submitting there may cause delays and denials).
- Phone submissions: call the number on the back of the member's ID card.
Services without authorization are not reimbursable
If you do not submit a prior authorization request, or if the request is denied, any services provided on or after June 15, 2026 are not eligible for reimbursement.
Provide required clinical documentation with the authorization request
Include the following clinical documentation when submitting a prior authorization request to support medical necessity and expedite review.
- Treating physician's notes that include the recommended level of care.
- Recommended treatment frequency (expected days per week and hours per day).
- Medication information, including MOUD and MAUD where applicable.
- Initial clinical assessment documenting symptoms and functional impairments.
- Service plan goals and documentation of current progress toward goals.
- Discharge/step-down plan with projected discharge date and post-discharge treatment needs.
Monitor limited authorizations and request renewals before expiration
Authorizations will be issued as limited approvals (varying units and end dates) on a trial basis; providers must submit a new prior authorization before the approved units are exhausted or the authorization end date is reached.
- Prior authorization implemented on a trial basis for a minimum of 6 months.
- Monitor the authorization for approved units and end date — request renewal ahead of whichever expires first (units or date).
- Limited authorizations have staggered units/end dates to manage concurrent authorization needs.
