What is the Molina Healthcare prior authorization fax number?

Each Molina Healthcare state plan and line of business prints its own prior authorization fax number, so the number to use follows the member's Molina plan. Texas Medicaid/CHIP outpatient requests go to 866-420-3639, Wisconsin Medicaid inpatient and outpatient requests go to 877-708-2117, and Texas Marketplace prior authorizations go to 833-322-1061. In Arizona, California, Idaho, Nevada and Utah, Molina's state pages say medical-benefit faxes are not accepted from 2/1/2026.

Molina Medicare lists its numbers by request type in a guide that prints no state, with 844-251-1450 for prior authorizations including planned inpatient and behavioral health.

Which Molina fax number goes with which state and plan?

Molina's fax number depends on the state, the line of business (Medicaid, Marketplace or Medicare) and the request type, and the table gives each number as Molina's guide or form prints it. Where a row says medical-benefit faxes are not accepted from 2/1/26, Molina's own state page makes that statement.

Molina's providers home page has a state selector, and the state prior authorization pages it opens cover the states and plans this table does not hold.

What do you send with a Molina prior authorization fax?

A Molina prior authorization fax carries the form Molina names for the request type, and Molina prints the fax number for each form below.

• Arizona pharmacy: the Medication Authorization Form
• Illinois Medicaid and Marketplace pharmacy: the Pharmacy PA Request Form
• Kentucky Medicaid physician administered drugs: form 'MAP 9 -MCO 2022'
• Michigan Medicaid and Marketplace drugs: the Drug Prior Authorization Form
• Nebraska Medicaid pharmacy: the Pharmacy Prior Authorization Request Form
• New Mexico Medicaid and Marketplace: the Prior Authorization Request Form (Version 5/23/2024)
• Texas Marketplace: the Texas Standard Prior Authorization Request Form for Health Care Services (NOFR001 | 0415)
• Molina Medicare Part D: the Request for Medicare Prescription Drug Coverage Determination form

Medical requests use the state's Pre-Service Review Guide or Prior Authorization Guide, the documents that print the medical numbers in the table. On a cover sheet, the recipient line names Molina and the state plan, beside the sender, a return fax number and the page count; the full list is in HIPAA fax cover sheet requirements. How to fax a prior authorization covers the sending steps.

Can you submit a Molina prior authorization online?

Yes, Molina's Washington and Mississippi pages name Availity as the online route: Washington's says to submit through Availity whenever possible, and Mississippi's says all requests go through Availity beginning 2027. Five Molina state pages, for Arizona, California, Idaho, Nevada and Utah, say medical-benefit prior authorization faxes are not accepted from 2/1/2026, and Idaho's Medicaid guide leaves transplant authorizations as its only fax line.

Massachusetts publishes a portal-only rule with listed fax exceptions: skilled nursing facility custodial authorization, Pharmacy Part D, Pharmacy Part B (J-Codes) and LTSS.

How do you fax Molina from a HIPAA fax account?

Molina requests go out from a Fax Pigeon account by browser or by email, to the number Molina prints for the member's state plan, line of business and request type. Uploads go as they are, whether a PDF, a Word document, an Excel or PowerPoint file or a phone photo, and a cover sheet is optional. Delivered faxes get delivery proof to keep with each request, paid plans fax from the practice's own number, and the whole team works from one inbox and one page allowance.

Unlimited people and a BAA signed at signup come with every plan, and the full BAA is readable at faxpigeon.com/baa before paying. Fax Pigeon's plans begin with Basic, $4.99 a month billed annually for a 200-page allowance shared by sending and receiving.

What if the Molina fax fails or the number changes?

A Molina fax without delivery proof is the one to recheck: open the state's prior authorization page from the state selector on the Molina providers home page and compare its number for the line of business and request type before sending again.

Molina's own documents disagree in two places. California Marketplace pharmacy is 866-508-6445 in the guide effective 01/01/2026, while the state page prints 888-836-0730 for individual and family plans. Washington Medicaid pharmacy is 800-869-7791 in the guide, while the state page prints 866-508-6445.

Some Molina documents are older than the 2026 guides: Arizona's guide is marked Rev 2024, Florida's Medicaid guide shows 01/01/2025, Kentucky's form is 'MAP 9 -MCO 2022' and New Mexico's form is Version 5/23/2024. Any other Medicaid managed care plan takes the same three checks: its state page, its guide's effective date and the number printed for the request type.
