Does Medi-Cal Pay Medicare Premiums in California?
The Short Answer
Yes — through the Medicare Savings Programs. When your parent is approved for QMB, SLMB, or QI in California, the state pays their Medicare Part B premium directly. For QMB specifically, the state also pays the Part A premium if your parent does not have premium-free Part A, plus all Medicare deductibles and coinsurance. The payment goes from the state to CMS, not through your parent's hands.
Medi-Cal itself — meaning full-scope Medi-Cal coverage — does not automatically pay Medicare premiums. The premium payment happens through the MSP program, which is administered under the Medi-Cal umbrella but has its own eligibility rules and aid codes.
How the Premium Payment Works
After the county approves your parent for an MSP, the data flows through CalSAWS to the Medi-Cal Eligibility Data System (MEDS), then to CMS, and finally to the Social Security Administration. SSA stops withholding the Part B premium from your parent's monthly Social Security check.
This process takes 60 to 90 days. During the transition, your parent keeps paying the premium through their Social Security deduction. Once SSA processes the buy-in, it refunds all premiums that were deducted during months of effective MSP coverage. The refund arrives as a lump-sum direct deposit or check.
The Part B premium in 2026 is $202.90 per month. Over a year, that is $2,434.80 returned to your parent's Social Security income — money that was previously being deducted before they could spend it.
Which Programs Pay Which Premiums
QMB (Aid Code 80) pays the most: Part B premium, Part A premium (if applicable), plus all Medicare deductibles and coinsurance. If your parent lacks premium-free Part A because they have fewer than 40 work quarters, QMB enrollment through California's Part A buy-in (Senate Bill 311) covers the full Part A premium — up to $565 per month in 2026 — paid by the state directly to CMS.
SLMB (Aid Code 8C) pays the Part B premium only. No cost-sharing coverage. Your parent still pays Medicare deductibles and coinsurance out of pocket (unless they have a Medigap policy or other coverage).
QI (Aid Code 8D) also pays the Part B premium only. The difference from SLMB is that QI is funded through a capped federal grant. In practice, this does not affect your parent's experience — the premium gets paid the same way.
QDWI (Aid Code 8A) pays the Part A premium only. This is for disabled working individuals who lost premium-free Part A because of earnings. It is the least common MSP tier.

What Full-Scope Medi-Cal Does Not Cover
If your parent has full-scope Medi-Cal but is not enrolled in an MSP tier, the state does not pay their Medicare premiums. Medicare and Medi-Cal are separate programs with separate funding. Full-scope Medi-Cal covers services that Medicare does not — dental, vision, long-term care — but it does not automatically cover the Medicare Part B premium.
The exception is SSI/SSP recipients. Under Senate Bill 311 and the 2023 CMS Final Rule, DHCS automatically enrolls eligible SSI/SSP recipients who have Part B into QMB. If your parent receives SSI, they should already have QMB coverage. Check their Notice of Action or call the county to confirm Aid Code 80 is on their record.
For everyone else — retirees on Social Security, people with pensions, anyone who does not receive SSI — the MSP application is required. It is not automatic. File Form MC 14A or apply through BenefitsCal, and the county evaluates your parent against the income and asset limits for each MSP tier.
Why Families Miss This
The most common reason eligible seniors keep paying their own Part B premium: they do not know the MSP exists, or they assume their income is too high. The 2026 gross monthly limit for QMB is $1,330 (single) — after the $20 disregard, that is $1,350 in countable income. For SLMB, the effective ceiling is $1,616. For QI, it is $1,816. Many seniors receiving Social Security checks in this range do not realize they qualify.
Another common miss: families assume the application process is too complicated or that it requires giving up control of their parent's finances. An MSP application asks for income and asset verification, not a transfer of assets or a lien on the home. MSP-only enrollment is explicitly exempt from Medi-Cal estate recovery.
