Medicare Part B Premium Assistance in California

Yes, California Can Pay the Part B Premium

The standard Medicare Part B premium is $202.90 per month in 2026 — $2,434.80 per year. For beneficiaries receiving Social Security, SSA usually deducts it from the monthly check. For someone living on $1,400 a month, that's nearly 15% of their income.

California's Medicare Savings Programs can eliminate this cost. Through the Medi-Cal system, the state pays the Part B premium directly for qualifying low-income seniors.

Three MSP tiers cover Part B premiums:

• QMB (income up to $1,330/mo single, $1,804 couple): Pays Part B premiums plus Part A premiums, deductibles, and coinsurance
• SLMB (income up to $1,596/mo single, $2,165 couple): Pays the Part B premium
• QI (income up to $1,796/mo single, $2,436 couple): Pays the Part B premium

After applying the mandatory $20 monthly income disregard, the effective countable income limits are slightly higher: $1,350 (QMB), $1,616 (SLMB), and $1,816 (QI) for individuals.

Asset limits are $130,000 for an individual, $195,000 for a couple. The family home and one car are exempt.

How the Premium Payment Actually Works

California doesn't send your parent a check for $202.90. The process works through the federal buy-in system:

1. The county approves MSP eligibility
2. The county updates the case in CalSAWS
3. DHCS transmits a buy-in transaction to CMS
4. CMS notifies SSA to stop withholding the Part B premium

This chain takes 60 to 90 days after county approval. During that transition, if your parent receives Social Security, SSA continues deducting the premium from the monthly check as if nothing changed.

When the system catches up, SSA issues a direct-deposit refund or check for Part B premiums it deducted for months that should have been covered. For SLMB and QI, which allow up to three calendar months of retroactive coverage before the month of application, the refund can cover premiums for those months if your parent was eligible.

The Part A Premium Too

If your parent lacks premium-free Part A — common among immigrants and people with fewer than 40 quarters of U.S. work history — the full Part A premium for someone with fewer than 30 work quarters is $565 per month in 2026. That's $6,780 per year on top of the Part B premium.

QMB covers this entirely. And since California became a Part A Buy-In state on January 1, 2025 (under Senate Bill 311), your parent can apply for QMB and Part A enrollment simultaneously through the county welfare office at any time of year. No visit to Social Security, no waiting for the annual General Enrollment Period.

The state pays the full Part A premium directly to CMS. Your parent gets both Medicare parts at zero premium cost.

Don't Cancel Part B While Waiting

This is the single most important warning: never cancel Part B while an MSP application is pending or while waiting for the buy-in system to process.

Canceling Part B terminates Medicare coverage and invalidates the MSP application. Your parent would then need to re-enroll during the next General Enrollment Period (January 1–March 31). Part B coverage starts the month after they sign up during that period, so canceling can leave a gap in coverage and MSP eligibility.

Continue paying the premium until SSA adjusts the benefit or the premium bill is cleared. Once processing completes, SSA refunds premiums it withheld for months that should have been covered.

How to Apply

Apply through BenefitsCal (benefitscal.com), your county welfare office, or by submitting Form MC 14A. Bring proof of income (Social Security award letter), a copy of the Medicare card, bank statements for the current month, and California ID. If applying for a parent, file Form MC 382 first to establish yourself as authorized representative.
