Kaiser Permanente does not have one fax number. It runs separate health plans by region, and each has its own appeals lines. In California, Senior Advantage (Medicare) members fax requests that qualify for a fast decision to the Expedited Review Unit at 1-888-987-2252, and Part D drug appeals to 1-866-206-2974. California's Grievance & Appeals Operations fax is 855-414-2318. In Washington, member appeals go to 1-844-660-0720. If your denial notice shows a different number, use the one on the notice.

This guide lists the Kaiser Permanente fax numbers we could verify on Kaiser's own websites and documents, says which region and plan each belongs to, and explains what to send.

  • Kaiser is regional. California, Washington, Colorado, Georgia, Hawaii, the Mid-Atlantic States, and the Northwest all run separate plans.
  • Verified numbers from Kaiser's 2026 Evidence of Coverage and official member forms
  • Standard Senior Advantage appeals go to the address on your denial notice

Why Kaiser numbers depend on your region

Kaiser Permanente is an integrated system: the health plan, hospitals, and medical groups work together, but the health plan is organised by region. Kaiser Foundation Health Plan, Inc. covers Northern and Southern California, and there are separate Kaiser health plans for Washington, Colorado, Georgia, Hawaii, the Mid-Atlantic States, and the Northwest.

Each region publishes its own Evidence of Coverage, member forms, and appeal contacts. Within a region, Medicare (Senior Advantage), employer and individual plans, federal employee (FEHB) plans, and Medicaid plans each have their own process. Your ID card and plan documents show which plan you have.

Verified Kaiser Permanente fax numbers

These numbers come from Kaiser Permanente's official websites (kp.org, healthy.kaiserpermanente.org, and Kaiser's regional and plan sites) and documents hosted there. Each applies only to the region, plan, and request shown.

Notes on these numbers:

  • Southern California Senior Advantage members have a separate 2026 Evidence of Coverage. Check Chapter 2 of your own EOC for its contact table before faxing.
  • FEHB claim disputes in Northern California go to a different place: Kaiser Permanente, Special Services Unit, P.O. Box 7136, Pasadena, CA 91109, or 800-464-4000. The 855-414-2318 fax is for the other appeal types.
  • Colorado, Georgia, Hawaii, Mid-Atlantic States, and Northwest members: we have not listed numbers for these regions because the documents we found were older provider manuals or forms. Use your denial notice or call Member Services.

The number on your denial notice wins

Kaiser's own 2026 Senior Advantage EOC says it plainly: for a standard appeal, write to the address shown on the denial notice. The notice comes from the team that decided your case, so its contact details, including any fax number, take priority over this page.

If you have lost the notice, call Member Services on your ID card. You can also file many complaints and appeals online through kp.org, which Kaiser points to in its FEHB fact sheet.

What to include in a Kaiser appeal

Kaiser's Northern California FEHB fact sheet sets out what it wants with both standard and urgent appeals, and the same list works for most Kaiser plans:

  • Your name and medical record number
  • A copy of the decision you are appealing
  • A statement of why you think the decision was wrong, tied to specific benefit terms in your plan documents
  • Supporting documents, such as doctors' letters, medical records, operative reports, bills, and EOBs

If someone else is filing for you, include an authorized representative form. In Southern California, Kaiser's non-Medicare form can be faxed to 855-414-2318. Senior Advantage members can get an Appointment of Representative form from Member Services, as the 2026 EOC explains.

How to fax Kaiser Permanente, step by step

  1. Identify your region and plan type from your ID card or plan documents.
  2. Check the denial notice for a fax number or address. Use the table only if there is none.
  3. Decide whether the request is urgent. The Expedited Review Unit line is for requests that qualify for a fast decision.
  4. Write a cover sheet with your name, medical record number, what you are appealing, and the page count.
  5. Attach the decision, your statement, and the evidence, and send it all in one fax.
  6. Keep the confirmation with a copy of what you sent.

No fax machine is needed. You can send a fax online for $2.99, with no subscription and no account, and get the delivery confirmation by email. To gather records from outside providers, see faxing medical records.

Common mistakes with Kaiser faxes

  • Using another region's number. A Washington appeal faxed to California Grievance & Appeals Operations reaches a different health plan.
  • Sending a standard appeal to the expedited line. The Expedited Review Unit handles fast decisions only.
  • Mixing up medical and Part D lines. Senior Advantage drug appeals go to the Part D Unit, not the medical appeals team.
  • No medical record number. Kaiser files are keyed on it, and your name alone can match several members.
  • Missing the decision letter. Without it, reviewers have to work out which decision you are challenging.

Faxing Kaiser Permanente works when the region, plan, and request type match the line, your medical record number is on every page, and you keep the confirmation.

Frequently asked questions

What is the Kaiser Permanente appeals fax number?

It depends on the region and plan. Kaiser's 2026 Northern California Senior Advantage Evidence of Coverage lists 1-888-987-2252 for requests that qualify for a fast decision, and 1-866-206-2974 for Part D drug appeals. Kaiser Foundation Health Plan of Washington lists 1-844-660-0720 on its member appeal request form.

What is the fax for Kaiser Permanente California Grievance & Appeals Operations?

Kaiser Permanente lists 855-414-2318 for California Grievance & Appeals Operations, P.O. Box 939001, San Diego, CA 92193. It appears on Kaiser's Southern California authorized representative form for non-Medicare members and on its Northern California FEHB appeals fact sheet.

Can I fax a standard Senior Advantage appeal?

Kaiser's 2026 Evidence of Coverage tells members to send a standard medical appeal to the address on the denial notice, and to use the Expedited Review Unit fax only for fast decisions. If your denial notice lists a fax number, you can use it.

How long do I have to appeal as a federal employee with Kaiser?

Kaiser's Northern California FEHB fact sheet says you can ask for a review within six months of the initial adverse benefit determination, and must finish Kaiser's internal appeal before asking OPM to review it, unless Kaiser failed to follow the claim rules.

Do I need a fax machine to fax Kaiser Permanente?

No. An online fax service sends the same fax from your browser or phone and gives you a delivery confirmation to keep with your appeal.
