Oklahoma’s Medicaid prior authorization form, the HCA-12A, is the standard petition providers send to the Oklahoma Health Care Authority (OHCA) to get a SoonerCare service approved before it’s delivered. To complete it successfully, you need the member’s SoonerCare ID, the rendering and referring providers’ NPIs, the correct diagnosis and procedure codes, and clinical documentation showing the service meets SoonerCare’s medical necessity standard. Submit through the SoonerCare Provider Portal or by fax to the Medical Authorization Unit.
When the HCA-12A Is the Right Form
The HCA-12A covers most prior authorization requests: durable medical equipment, medical services, therapy, behavioral health, dental services beyond preventive care, and other categories such as genetic testing, out-of-state services, and waiver programs.1Oklahoma Health Care Authority. Medical Authorization Unit
Two situations call for a different form or a different path:
- If you’re attaching photos or videos, or amending an existing authorization, add the HCA-13A Prior Authorization Attachment Form Cover Sheet. It collects your NPI, the member’s ID, and the existing prior authorization number when you’re amending.2Oklahoma Health Care Authority. HCA-13A Prior Authorization Attachment Form Cover Sheet
- Pharmacy prior authorization doesn’t use the HCA-12A. Pharmacies and prescribers contact OHCA’s contracted pharmacy prior authorization processor directly, with clinical exception petitions going to the Medication Authorization Unit.3Legal Information Institute. Oklahoma Administrative Code 317-30-5-77.2 – Prior Authorization

What to Gather Before You Start
Having everything in hand before you open the form is the single easiest way to avoid a returned request. OHCA reviews petitions based on the information submitted, including the relevant procedure or drug code and any supporting documentation the agency requires.5Legal Information Institute. Oklahoma Administrative Code 317-30-3-31 – Prior Authorization for Health Care-Related Goods and Services
Pull together:
- Member information. The patient’s full name, date of birth, and SoonerCare Member Identification Number (also called the Recipient ID or RID).
- Provider information. The National Provider Identifier (NPI) for both the rendering and the referring provider, the federal tax ID, and a phone and fax number for the billing office.
- Service codes. The CPT code for a procedure, HCPCS code for durable medical equipment, or NDC for a pharmacy item, plus the ICD-10 diagnosis code that supports the request.
- Clinical documentation. Recent medical records, a certificate of medical necessity when applicable, and a written clinical justification tying the request to SoonerCare’s coverage criteria.
How OHCA Judges Medical Necessity
Every request is measured against SoonerCare’s six-part medical necessity standard. The service must be consistent with accepted medical practice for diagnosing or treating an illness, disease, or disability; the documentation must contain enough objective evidence to justify the need; the treatment must be based on reasonable and predictable health outcomes; it must be required for reasons beyond convenience; it must be delivered in the most cost-effective setting; and it must be appropriate for the member’s age and health status.6Legal Information Institute. Oklahoma Administrative Code 317-30-3-1 – General Provisions
Therapy and durable medical equipment requests draw the closest scrutiny on that last criterion. Reviewers want to see that the plan targets a realistic functional goal, not just a diagnosis. Measurable goals in the clinical justification — for example, “patient will achieve independent transfers within 60 days” — strengthen a request considerably.
Completing the HCA-12A Section by Section
Member Data
Enter the patient’s full name, date of birth, and SoonerCare RID exactly as they appear on the member’s SoonerCare card. A transposed digit in the RID is one of the most common reasons a request bounces back. Verify it against the card or the eligibility screen in the provider portal before moving on.
Provider Section
Enter the NPI for the rendering provider (the one performing the service) and, if different, the referring provider. Include the federal tax ID, the provider’s name, and a working phone and fax for the billing office. The clinical records you submit must list the same rendering provider named here. A mismatch between the form and the chart creates delays.
Service Detail
This is where the clinical case gets made. Enter the ICD-10 diagnosis code that supports the service, followed by the CPT or HCPCS procedure code. Specify the quantity of items or units, the requested start date, and the duration of treatment. For durable medical equipment, note whether the item is a purchase or a rental. Attach the clinical documentation you gathered earlier. The chart must show that the member’s condition meets the coverage criteria and that every answer on any certificate of medical necessity is backed up in the records.7Oklahoma Health Care Authority. Oklahoma Administrative Code 317-30-5-211.3 – Prior Authorization (PA)
Leave no field blank. OHCA staff check every clerical item for completeness and accuracy before the request is routed to clinical review. An incomplete form is returned, and the clock restarts when you resubmit.
Submitting the Request
Through the Provider Portal
The preferred route is the SoonerCare Provider Portal at ohcaprovider.com. Providers who haven’t registered can create an account through the “Register Now” link on the homepage.8HCP Provider Portal. HCP Provider Portal – Home
Once logged in, go to the authorization section to start a new request. The portal lets you attach medical records and supporting documentation to the submission, delivers an electronic confirmation when OHCA’s system accepts the request, and shows the status of pending authorizations in your account’s activity logs.
By Fax
If the portal isn’t an option, fax the completed HCA-12A with all supporting documentation to one of the following numbers:
- OKC Metro: (405) 271-4014
- Toll Free: (800) 224-4014
Include the HCA-13A cover sheet if the submission involves photos, videos, or an amendment. For other faxed requests, use a clear cover page identifying the member, the provider, and the authorization type so the documents reach the correct review unit.
How Long Review Takes
OHCA does not publish a single statutory deadline for all non-pharmacy prior authorizations. Processing times depend on the complexity of the request and the completeness of the submission. Requests that arrive with full documentation move faster than those that need follow-up.
Notifications go to the provider through the portal and to the member by mail. The written notice states whether the request was approved, partially approved, or denied, and gives the reasoning behind the decision.
If the Request Is Denied
A denial can be appealed, and the deadlines are strict. The member or an authorized representative files form LD-1, the Member Complaint/Grievance Form, within 30 calendar days of the date OHCA mailed the denial notice. The form must be complete and include supporting documentation. If the LD-1 arrives late or incomplete, OHCA’s administrative law judge will decline to hear the appeal.9Oklahoma Health Care Authority. OHCA Policies and Rules – Appeals
The denial notice itself is the starting point for the appeal. Federal rules require the notice to explain specifically why coverage was denied and what information would be needed to approve it.10Centers for Medicare & Medicaid Services (CMS). Form Instructions for the Notice of Denial of Medical Coverage (or Payment) CMS-10003-NDMCP Read that explanation carefully. If the denial cites insufficient clinical documentation, the appeal should include updated records, a more detailed letter of medical necessity from the treating provider, or both. If the denial says the service doesn’t meet coverage criteria, address each of the six medical necessity standards in OAC 317:30-3-1 point by point. A provider’s letter that explains why the patient’s condition satisfies each standard carries far more weight than a generic statement that the service is medically necessary.
