How Molina splits its fax lines

Molina sells three kinds of plan, mostly to people with public or subsidized coverage:

  • Medicaid plans, run under contract with each state
  • Medicare plans, including plans for people with both Medicare and Medicaid
  • Marketplace plans, bought through HealthCare.gov or a state exchange

Each plan type in each state has its own appeals and grievances team. A Wisconsin Marketplace appeal sent to the Texas line has to be rerouted, if it is noticed at all.

An appeal asks Molina to change a decision, such as a denied service or claim. A grievance is a complaint about anything else, such as service, wait times or how you were treated. Molina uses the same fax for both on the Marketplace pages below.

The number on your letter wins

A Molina denial or notice letter tells you how to appeal and by when. That contact information belongs to the team holding your case, so it beats any general number. If you have no letter, call member services on your ID card and ask for the appeals fax for your plan and state.

For urgent medical situations, ask for an expedited (fast) appeal by phone rather than relying on a fax alone.

How to fax Molina, step by step

  1. Confirm your plan type and state on the ID card.
  2. Find the number on your letter, or in the table if it matches your plan.
  3. Write your request. Say which decision you are appealing, or what your grievance is about, and what you want Molina to do.
  4. Add your member ID and any claim or authorization number on every page.
  5. Attach evidence, such as the denial letter, bills, or a doctor's note.
  6. Fax it and keep the confirmation.

You can send a fax online for $2.99, with no subscription and no account. The confirmation arrives by email.

Mistakes that slow down a Molina appeal

  • Using another state's fax. Molina's teams are organized by state.
  • Mixing Medicare and Marketplace lines. They are different plans with different rules.
  • Using old Molina links. Molina has moved its Marketplace appeals pages; older addresses now show "page not found."
  • Faxing a prior authorization where Molina has moved to Availity.
  • Missing the deadline, such as the 60-day limit for Medicare grievances.
