Key points
- Social Security announced a 3.6% COLA for 2027 on October 14, 2026. The official 2027 Part B premium had not been announced as of October 15; treat premium forecasts as estimates.[1][16]
- The official 2026 standard Part B premium is $202.90, although some beneficiaries pay more based on income.[1][2]
- Some Medicare Advantage plans may help pay all or part of the Part B premium, but availability and amount vary by plan, county, and year; compare the whole plan.[3][2][4]
- VA health care does not become Medicare Advantage coverage. VA and Medicare have separate rules, and TRICARE For Life beneficiaries have their own Part A and Part B requirements.[5][6]
The short answer: the 2027 Social Security COLA is 3.6%, but the official 2027 Part B premium had not been announced as of October 15, 2026. The amount you keep depends on your benefit and actual deductions. The useful question is what your current premium is, whether you qualify for a Special Enrollment Period, and what your plan and county actually offer.[1][7][16]
What was known about the 2027 COLA and Part B premium
SSA announced the official 2027 COLA of 3.6% on October 14, 2026. A forecast for the 2027 Part B premium is still an estimate. As of October 15, 2026, the official standard Part B premium available for reference was the 2026 amount of $202.90 per month; some people pay more because of income-related adjustments.[1][2][16]
What Medicare Part B actually costs
Most people have their Part B premium deducted from Social Security. If you are not receiving Social Security, Medicare generally bills you every three months. The premium is only one part of your health-care costs: deductibles, copayments, coinsurance, networks, authorizations, drug costs, and plan limits may also matter.[8][2]
A Medicare Advantage plan must have Part A and Part B, and you must keep paying the Part B premium. A plan may also have its own premium and cost-sharing rules. Compare the Evidence of Coverage and Medicare Plan Compare instead of judging a plan by one advertised number.[2][9]
How a Part B premium reduction works
Some Medicare Advantage plans may help pay all or part of your Part B premium. This is called a Part B premium reduction. It is not a refund or cash payment, and it is not available with every plan. The amount and availability depend on the plan, county, and year; the reduction may appear as a lower Social Security or Railroad Retirement deduction or a smaller Medicare bill.[3][10][11]
A plan-specific reduction does not make all care cost $0 and does not tell you the total cost of care. Some plans have a $0 monthly plan premium, but you still pay your Part B premium and may have copayments, deductibles, network restrictions, prior authorization, drug costs, and an annual out-of-pocket limit. In 2026, KFF reported that 32% of individual Medicare Advantage plans offered some Part B premium reduction; many did not.[3][2][4]
An illustrative account example—not a promise
A member whose 2026 standard Part B premium is $202.90 could have a plan-stated $185 Part B premium reduction, leaving $17.90 of that standard premium. That does not mean $17.90 is the member's total health-care cost. Deductibles, copayments, coinsurance, drug costs, network rules, authorizations, and the plan's annual out-of-pocket limit still apply and vary by plan and year. Verify current plan documents and Medicare Plan Compare for your county.[1][2][3]
VA health care and Medicare Advantage are separate
Medicare Advantage enrollment does not replace your VA eligibility, but it is separate coverage with its own network, cost-sharing, authorization, and claims rules. VA says that having other health insurance does not change the VA health care benefits you can get, and you generally choose which benefits to use each time you receive care. Non-VA community care must be authorized by VA first, subject to the applicable rules.[5][12]
If you have TRICARE For Life
TRICARE For Life requires Medicare Part A and Part B. Part C and Part D are not required for TFL. Medicare generally pays first for services both programs cover, and TRICARE pays last.[6][13]
If a TFL beneficiary chooses Medicare Advantage, TRICARE says nonemergency care must come through the plan's network, copayments may apply at the time of service, and paper claims may be needed for TRICARE reimbursement. Review the plan and TRICARE rules before enrolling; do not assume that an advertised Part B reduction explains every cost or claim.[6]
Enrollment timing matters more than a forecast
Most people have a seven-month Initial Enrollment Period around age 65: three months before the birthday month, the birthday month, and three months after. Whether you should enroll then depends on your current coverage and circumstances. Job-based coverage may qualify for a Special Enrollment Period; VA or TRICARE coverage does not by itself make every Medicare decision interchangeable. Check Medicare.gov and the applicable benefits administrator before delaying Part B. If you owe a Part B late-enrollment penalty, it can generally continue as long as you have Part B.[14][7][5]
For people already enrolled in Medicare Advantage, the Medicare Open Enrollment period is October 15 through December 7 for changes effective January 1. Review your plan's Annual Notice of Change, provider network, prescriptions, premiums, cost sharing, and out-of-pocket limit.[9][2]
- Confirm the official figures The official 2027 COLA is 3.6%. Use the CMS announcement, not a forecast, for the final 2027 Part B premium.[1][16]
- Identify your coverage Separate VA health care, TRICARE For Life, CHAMPVA, employer coverage, retiree coverage, and COBRA; their enrollment rules are not interchangeable.[5][6][15][14]
- Compare the entire plan If you consider Medicare Advantage, review the network, referrals, authorizations, prescriptions, premiums, cost sharing, and annual out-of-pocket limit—not just a Part B premium reduction.[2][9]
- Ask before delaying Part B Confirm your situation with Social Security, Medicare, VA, or a SHIP counselor before delaying Part B.[14][7]

Common questions
Does Medicare take a 2027 COLA?
The 2027 COLA is 3.6%. As of October 15, 2026, the official 2027 Part B premium had not been announced. The amount of your raise left after Medicare depends on your actual premium and other deductions. Your Part B premium and any plan-specific reduction also depend on your circumstances and plan.[1][2][16]
Is a Part B premium reduction cash?
No. It is a plan-specific reduction offered by some Medicare Advantage plans in some areas. It may lower the Social Security or Railroad Retirement deduction or Medicare bill; it is not cash and does not eliminate other plan costs.[3][10][11]
Does a $0 Medicare Advantage premium mean there are no other costs?
No. You still pay your Part B premium, and deductibles, copayments, networks, authorization rules, drug costs, and the plan's annual out-of-pocket limit can apply.[3][2]
Can I delay Part B because I use VA health care?
VA health care is not the same as current-employment group coverage for the usual Part B Special Enrollment Period. Check your specific circumstances with Medicare, Social Security, VA, or SHIP before delaying Part B.[5][14][7]
Do TRICARE For Life beneficiaries need Medicare Part B?
Yes. TFL requires Part A and Part B. Part C and Part D are not required for TFL, but choosing Medicare Advantage can add network, copayment, and claims rules.[6]
