A pharmacy benefit change is easiest to manage before the claim rejects at the counter. In fall 2025, Medi-Cal Rx gave members and providers advance notice that coverage for GLP-1 drugs used for weight loss would change on January 1, 2026. The practical task for patients is to confirm what their current prescription is being used for, whether a new authorization may be needed, and who should handle the next step.
Quick Answer
Starting January 1, 2026, Medi-Cal Rx will no longer cover GLP-1 drugs when they are used for weight loss only, with a limited exception for members younger than 21 under federal EPSDT requirements. Some GLP-1 drugs may still be considered for other covered uses under Medi-Cal Rx rules. If you currently use one of these prescriptions, review the indication, prior-authorization status, refill timing, and next steps with your prescriber before the end of 2025.
What Changes on January 1, 2026
Medi-Cal Rx’s 2025–26 state budget updates announced that GLP-1 drugs will no longer be covered when they are used for weight loss only beginning January 1, 2026. The change applies statewide to Medi-Cal members.
That does not mean every GLP-1 prescription automatically loses coverage for every reason. The November 2025 Medi-Cal Rx coverage update separates weight-loss use from other uses and explains that some prescriptions may still be reviewed under different coverage criteria.
Because the coverage pathway depends on why the medication is being prescribed, patients should avoid assuming that another person’s coverage result will apply to them.
If the GLP-1 is used for weight loss only
Medi-Cal Rx announced that weight-loss use would no longer be a covered pharmacy benefit beginning January 1, 2026. Previously approved authorizations for certain weight-loss GLP-1 products were scheduled to end December 31, 2025.
If the GLP-1 is being used for another covered reason
Some GLP-1 prescriptions may still be considered under Medi-Cal Rx rules for non-weight-loss uses. The exact pathway depends on the product, the documented reason for use, and whether Medi-Cal Rx requires an approved prior authorization.

What to Review in November Before the Change Takes Effect
- Confirm why the prescription is being used.
- Coverage rules can differ depending on the diagnosis or reason documented by the prescriber.
- Check whether a prior authorization is already in place.
- Ask the prescriber or pharmacy whether an authorization exists and when it is scheduled to end.
- Review your refill timing before December 31.
- Do not assume an early refill is automatically available. Ask what your current benefit allows and what the next fill date is.
- Discuss next steps with the prescriber managing your care.
If the benefit change affects your prescription, treatment decisions should come from the prescriber rather than from a coverage guess at the pharmacy counter.

Questions to Bring to Your Prescriber
Keep the conversation focused on your own prescription rather than on general news about GLP-1 coverage.
01. What diagnosis or treatment reason is documented for this prescription?
02. Will a new prior authorization be needed after January 1?
03. If coverage changes, what should happen before my current supply runs out?
04. Should the pharmacy expect a new prescription, new authorization, or different billing information?
If Coverage Is Denied After the Change
Medi-Cal Rx tells members who receive a Notice of Action denying GLP-1 coverage that they have State Hearing rights. The notice should explain the deadline and instructions that apply to that decision.
Do not ignore the notice
For benefit questions, members can also contact the Medi-Cal Rx Customer Service Center at 1-800-977-2273. For treatment changes, contact the prescriber managing the medication.

Frequently Asked Questions
Does Medi-Cal Rx stop covering every GLP-1 drug on January 1, 2026?
No. The statewide change specifically removes coverage for GLP-1 drugs when they are used for weight loss only. Some prescriptions may still be reviewed for other covered uses under Medi-Cal Rx rules, depending on the drug, diagnosis, and authorization requirements.
What happens to an existing authorization for a weight-loss GLP-1?
Medi-Cal Rx’s fall 2025 notices said previously approved authorizations for certain weight-loss GLP-1 products would end December 31, 2025. If you are unsure whether that applies to your prescription, ask your prescriber or pharmacy to verify the current authorization details.
Can members younger than 21 still receive coverage for weight-loss use?
There is a limited pathway under federal EPSDT requirements. Medi-Cal Rx states that a prior authorization must be submitted and approved for a member younger than 21 who needs a GLP-1 drug for weight loss.
Should I stop my medication before January 1 if coverage is changing?
No. A benefit change is not an instruction to stop or alter a prescription. Contact the prescriber managing your care before changing how you use the medication.
Who can answer a Medi-Cal Rx benefit question?
The Medi-Cal Rx Customer Service Center can answer benefit and authorization-status questions at 1-800-977-2273. Your pharmacy can help with claim and refill questions, while treatment decisions should be directed to your prescriber.
