Help with pharmacy prescriptions (Medi-Cal Rx)

Medi-Cal’s statewide service for covered medicines billed by a retail or mail-order pharmacy.

What it is

Medi-Cal’s statewide service for covered medicines billed by a retail or mail-order pharmacy.

A pharmacy rejection goes to a different desk from the health plan’s medical claims. Medi-Cal Rx may need more information from the prescriber. The exact rejection message helps the clinic find the next step.

Who can get it
  • The benefit covers Medi-Cal members, including CCS/Medi-Cal children.
  • Its scope is covered outpatient drugs billed on pharmacy claims, under the arrangement beginning January 1, 2022.
What you get
  • A response to a pharmacy coverage request generally comes within 24 hours. It may seek more information and does not promise approval or dispensing.
  • One statewide pharmacy help desk at 800-977-2273.
What you get
  • Medi-Cal Rx reviews pharmacy prior-authorization requests with a 24-hour response standard.
  • A pharmacy prior-approval request generally needs a response within 24 hours. The answer may approve, deny or ask for more information. It does not guarantee approval or medicine within 24 hours. Ask the pharmacy about the claim status and any urgent-supply process.
  • Clinic-administered chemo is a medical claim routed to the plan or CCS.
If you decide to apply
  1. Ask Medi-Cal Rx for help with your child’s Medi-Cal number, the drug name and the pharmacy’s exact rejection message.
  2. Ask the prescriber whether a coverage request is needed and who will answer any request for more medical information.

What happens next
  • An approval lets the pharmacy process the covered prescription.
  • If the decision is put on hold for more information, the clinic sends what was requested.
  • A denial can be addressed with additional clinical information or a state hearing through 800-743-8525.
Good to know

Chemo given in the clinic usually uses a medical claim through the plan or CCS, rather than a pharmacy claim.

What else to know
  • The pharmacy’s exact rejection message helps identify the problem.
  • The health plan’s medical-benefit desk and Medi-Cal Rx handle different claims.
Official sources
Ask your social worker

“Would Medi-Cal Rx or the health plan handle our child’s medicine, and what approval limits might apply? If there is a delay, would a review help? Could you help the prescriber send what is needed?”

Why I’m asking: I want to know who can resolve a prescription problem.

Who does what

The three parts, side by side. The agency decides; nobody on this page does.

You

Call 800-977-2273 when a prescription is rejected and tell the clinic what Medi-Cal Rx asked for.

Your social worker

The clinic pharmacist or nurse sends the prior authorization to Medi-Cal Rx and follows up on a deferral.

The care team

Records and letters when the application asks for them.

Who decides
Medi-Cal Rx
Ask the care team
“The pharmacy rejected my child's prescription. Has the prior authorization gone to Medi-Cal Rx, and what did it ask for?”

How to apply

First step: Save 800-977-2273 in your phone. When a pharmacy rejects a prescription, call it and then the clinic.

  1. If a prescription is rejected, call 800-977-2273 and ask what is missing.
  2. Ask the clinic to send the prior authorization to Medi-Cal Rx, not the plan.
  3. Ask for the 24-hour answer and whether it was a deferral.

Official application / program page ↗

Where it starts: The pharmacy submits the claim; the prescriber sends any prior authorization to Medi-Cal Rx

What to gather

  • The child's Medi-Cal number
  • The drug name and the pharmacy's rejection message

How long: Prior authorization: an answer within 24 hours of the request.

What a yes looks like

The pharmacy fills the prescription. The authorization shows approved.

What a no looks like, and the next move

A denial from Medi-Cal Rx. The clinic can resubmit with more information, and you can ask for a state hearing (800-743-8525).

Watch out

  • Do not call the health plan about a pharmacy rejection. Call Medi-Cal Rx.
  • The 24-hour answer can be a deferral asking the prescriber for more. Ask the clinic to respond the same day.
  • Chemo given in the clinic is a medical claim, not a pharmacy claim. That authorization goes to the plan or CCS.

The numbers and the rules

The arcane layer, kept on purpose. Checked September 8, 2026.

One statewide pharmacy desk for Medi-Cal prescriptions, with a 24-hour prior-authorization answer.

  • $24 (the answer can be a deferral) — Prior-authorization answer

Covers: Pharmacy prescriptions for anyone on Medi-Cal, CCS included · Prior-authorization review with a 24-hour answer

What it costs the family: None.

The eligibility facts, as published
