Does Medi-Cal Pay Medicare Deductibles and Copays? 2026 California Guide
If you have both Medicare and Medi-Cal in California, you may wonder whether Medi-Cal will pay your Medicare deductible, copayment, or coinsurance.
The answer depends on your Medi-Cal status and whether you qualify for a Medicare Savings Program such as the Qualified Medicare Beneficiary (QMB) program.
If you qualify for the Qualified Medicare Beneficiary (QMB) program, Medicare providers generally cannot bill you for Medicare-covered deductibles, coinsurance, or copayments. California may also help pay Medicare Part A and Part B premiums for eligible beneficiaries.
1. How Do Medicare and Medi-Cal Work Together?
People who qualify for both Medicare and Medi-Cal are often called dual eligible beneficiaries.
For most Medicare-covered medical services, Medicare is the primary insurance. Medi-Cal may provide additional coverage and help with certain costs after Medicare.
Medi-Cal may also cover services that Medicare does not fully cover, including certain long-term services and supports.
2. Does Medi-Cal Automatically Pay Every Medicare Deductible?
Not necessarily.
Having a Medi-Cal card does not mean that every Medicare deductible or copayment is automatically paid in every situation.
The strongest Medicare cost-sharing protection generally applies to people who qualify for the Qualified Medicare Beneficiary (QMB) program.
Do not assume that “Medi-Cal pays everything.” Your specific Medi-Cal and Medicare Savings Program eligibility determines which Medicare costs are covered.
3. What Is the QMB Program?
QMB stands for Qualified Medicare Beneficiary. It is one of the Medicare Savings Programs available to eligible people with limited income and resources.
In California, the QMB program can help pay:
- Medicare Part A premium, if applicable
- Medicare Part B premium
- Medicare deductibles
- Medicare coinsurance
- Medicare copayments for Medicare-covered services
4. Can a Doctor Bill a QMB Patient for a Medicare Deductible or Copay?
Generally, no.
Federal Medicare rules prohibit Medicare providers from billing QMB beneficiaries for Medicare-covered deductibles, coinsurance, and copayments.
California DHCS also explains that dual eligible beneficiaries and QMB members should not be balance billed for Medicare cost sharing.
If Medicare covers a doctor visit and you are enrolled in QMB, the doctor generally cannot require you to pay the Medicare deductible, coinsurance, or copayment for that Medicare-covered service.
5. What If My Doctor Does Not Accept Medi-Cal?
This is a common concern.
DHCS explains that people with Medicare and Medi-Cal can generally use Medicare providers even if the provider does not participate in Medi-Cal or is not part of the member's Medi-Cal managed care plan.
For Medicare-covered services, QMB billing protections still apply to Medicare providers.
However, a provider may decide not to accept you as a new patient, so it is still a good idea to confirm that the office accepts Medicare before making an appointment.
6. What Is the 2026 QMB Income Limit in California?
California's DHCS lists the following 2026 gross income figures for the QMB program:
| Household | 2026 Monthly Income | 2026 Annual Income |
|---|---|---|
| Individual | $1,330 | $15,960 |
| Individual + Spouse | $1,804 | $21,640 |
DHCS notes that deductions may apply during the eligibility calculation. Therefore, even if your income is somewhat above the amounts shown above, you may still want to apply.
7. Is There an Asset Limit for QMB in California in 2026?
Yes.
Beginning January 1, 2026, California applies an asset limit to Medicare Savings Programs.
The limit is:
- $130,000 for one person
- +$65,000 for each additional household member, up to the applicable household limit
For example, the standard amount for two people is $195,000.
8. What Is SLMB?
SLMB stands for Specified Low-Income Medicare Beneficiary.
Unlike QMB, SLMB primarily helps pay the Medicare Part B premium.
For 2026, DHCS lists the SLMB gross monthly income amounts as:
- Individual: $1,596 per month
- Individual and spouse: $2,165 per month
9. What Is the QI Program?
QI stands for Qualifying Individual.
QI also helps pay the Medicare Part B premium, but it does not provide the same Medicare deductible and copayment protection as QMB.
For 2026, DHCS lists the QI gross monthly income amounts as:
- Individual: $1,796 per month
- Individual and spouse: $2,436 per month
DHCS also notes that a person receiving QI cannot also receive Medi-Cal.
10. QMB vs. SLMB vs. QI
| Program | Main Help |
|---|---|
| QMB | Part A and Part B premiums, plus Medicare deductibles and copayments |
| SLMB | Medicare Part B premium |
| QI | Medicare Part B premium |
QMB provides broader Medicare cost-sharing protection. SLMB and QI primarily help with the Medicare Part B premium.
11. What If I Receive a Medicare Bill Even Though I Have QMB?
If you are enrolled in QMB and receive a bill for a Medicare-covered deductible, coinsurance, or copayment, do not assume that you must pay it.
First, tell the doctor's office or medical provider that you are enrolled in QMB.
You can show both your Medicare card and your Medi-Cal or QMB information.
If the provider continues to bill you for Medicare cost sharing, Medicare recommends calling 1-800-MEDICARE (1-800-633-4227).
If you were improperly charged for Medicare-covered cost sharing while enrolled in QMB, Medicare states that you may have the right to a refund.
12. Does QMB Apply to Medicare Advantage?
QMB protections also apply when you receive Medicare-covered services through a Medicare Advantage plan.
If you are enrolled in a Medicare Advantage plan and believe you are being improperly charged for Medicare cost sharing, contact your plan and tell them that you have QMB.
13. What About Medi-Medi Plans?
California offers Medi-Medi Plans in participating counties for certain people who have both Medicare and Medi-Cal.
These plans coordinate Medicare and Medi-Cal benefits through one integrated plan.
If you are enrolled in a Medi-Medi Plan, use providers within the plan's network and contact the plan if you receive a bill you believe should not have been charged.
14. How Do I Apply for QMB or Another Medicare Savings Program?
California uses the Medi-Cal application process for Medicare Savings Programs.
You may apply:
- Online through BenefitsCal
- By mail
- By phone through your county social services office
- In person at your local county office
If you apply for Medi-Cal, the county can also evaluate whether you qualify for a Medicare Savings Program.
