For 2026, the standard Medicare Part B monthly premium is $202.90, with a $283 annual deductible, but higher-income individuals pay more, and some pay less due to income adjustments (IRMAA), while a late enrollment penalty can add to the cost. After the deductible, you typically pay 20% of Medicare-approved costs for services, plus potential Income-Related Monthly Adjustment Amounts (IRMAA) for higher earners.
For 2026, the standard Medicare Part B premium deducted from most Social Security checks is $202.90 per month, with higher premiums for higher incomes and a separate annual deductible of $283; some beneficiaries pay less due to the hold harmless rule. Your exact amount depends on your income from two years prior, and you'll also pay 20% coinsurance for most services after meeting the deductible.
When you use TRICARE For Life, you don't pay any enrollment fees, but you must have Medicare Part A and Part B. Medicare Part A is paid from payroll taxes while you're working. Medicare Part B has a monthly premium, which is based on your income.
No one is automatically exempt from Medicare Part B premiums, but many people avoid paying them by having other creditable coverage (like employer plans when still working), qualifying for Medicare Savings Programs (MSPs) through Medicaid due to low income, or having certain disabilities that qualify them for premium assistance. Those automatically enrolled in Medicare who don't need Part B right away (e.g., due to employer coverage) can delay enrollment without penalty.
Coverage is only for the Medicare- and TRICARE-eligible beneficiary. This means your new TFL coverage at age 65 doesn't extend to family members. Your spouse younger than age 65 would remain eligible for TRICARE Prime or TRICARE Select until they turn age 65 and become eligible for Medicare Part A and Part B.
You can avoid paying Medicare Part B premiums by delaying enrollment if you have creditable employer coverage (your own or spouse's job with 20+ employees) until that coverage ends (within 8 months to avoid penalties), or by qualifying for a Medicare Savings Program (MSP) to have state/federal funds pay for it due to low income. Other ways to save include using HSA funds, appealing high Income-Related Monthly Adjustment Amounts (IRMAA) for life changes, or enrolling on time during your Initial Enrollment Period.
Here are some of the biggest Medicare mistakes to avoid:
For most beneficiaries, the government pays a substantial portion — about 75% — of the Part B premium, and the beneficiary pays the remaining 25%.
Your CalPERS health coverage will automatically be canceled the first day of the month after you turn 65. Review Cancellation of CalPERS Health Coverage for information on reinstating your health coverage.
You Are a High Earner
The Income Related Monthly Adjustment Amount (IRMAA) is an additional fee you may have to pay on Medicare Part B and Part D if you earn above a certain income level.
You can reduce your Medicare Part B premium by applying for Medicare Savings Programs (MSPs) if you have low income, filing Form SSA-44 (Request for Reconsideration) for income drops after a life event (like retirement), or enrolling in a Medicare Advantage plan with a Part B "giveback" benefit. For those with higher incomes, using a Health Savings Account (HSA) or Qualified Charitable Distributions (QCDs) from an IRA can help lower the income used for premium calculations, say financial experts and CNBC.
Starting in 2025, there is an annual limit on what you pay out-of-pocket for prescription medications through Medicare and Medicare Advantage prescription drug plans. All prescription medications, including specialty medications, covered by Part D plans are included under this cap.
If you joined a Medicare Advantage Plan during your Initial Enrollment Period, you can change to another Medicare Advantage Plan (with or without drug coverage) or go back to Original Medicare (with or without a drug plan) within the first 3 months you have Medicare Part A & Part B.
The best people to talk to about Medicare are your local State Health Insurance Assistance Program (SHIP) (for free, unbiased advice) or your specific Medicare plan's customer service (for plan-specific questions). For enrollment, contact the Social Security Administration (SSA), while independent brokers can compare plans, and organizations like the NCOA or AARP offer resources and tools.
Part C (Medicare Advantage)
Part C is known as Medicare Advantage. It's an alternative to Parts A and B that bundles several coverage types, including Parts A, B, and usually D. It may also include: Vision.
Each fall, when we ask the IRS for information to determine next year's premiums, we ask for tax information to verify your reports of changes affecting your income-related monthly adjustment amounts, if any. We also ask the IRS for your two-year-old MAGI if we've temporarily used three-year-old MAGI.
If you can't afford Medicare Part B, you should immediately contact your State Medical Assistance (Medicaid) office to apply for a Medicare Savings Program (MSP), which can pay your Part B premiums and other costs if you have low income/resources, or explore options like Supplemental Security Income (SSI), or even look into Medicaid itself for comprehensive help, as delaying Part B can lead to lifetime penalties.
For spouses who do not qualify for the same health benefits from Medicare based on their spouse's work record, they still have other health insurance coverage options such as COBRA or a health plan under the ACA. They must pay premiums for either option.
Unmarried biological children, adopted children, and stepchildren are eligible for TRICARE until age 21 (or 23 if in college—see “College Students” below). Eligibility may extend beyond these age limits if your child is severely disabled.
The Survivor Benefit Plan (SBP) provides financial support to military spouses and/or children when a military member dies while on duty or after retirement. SBP provides eligible beneficiaries with a monthly payment known as an annuity. The recipient of an SBP annuity is referred to as the annuitant.
