Medicare premiums, particularly for Part A, do not stop at a specific age; rather, they are generally free starting at age 65 if you or a spouse worked and paid Medicare taxes for at least 10 years (40 quarters). While Part A is usually premium-free, you will generally continue to pay premiums for Medicare Part B and Part D regardless of age.
If you don't sign up for Medicare at 65, you risk paying late enrollment penalties for Part B (and potentially Part A if you pay premiums) and Part D, which increase your monthly costs permanently; you might also face coverage gaps if you don't have "creditable" employer coverage, leading to high out-of-pocket medical bills. You can delay signing up penalty-free if you have "creditable coverage" through an employer, but you must enroll during a Special Enrollment Period (SEP) when that coverage ends to avoid penalties.
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.
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.

The Centers for Medicare & Medicaid Services (CMS) has set the standard monthly Part B premium at $202.90 in 2026, an increase of $17.90, or just under 10 percent, from the 2025 premium of $185.00.
The extra $144 added to Social Security usually comes from the Medicare Part B Giveback benefit, offered by some Medicare Advantage (Part C) plans, which pays back some or all your Part B premium, showing up as extra money in your check if it's deducted from your Social Security. To qualify, you need Original Medicare (Parts A & B), pay your own Part B premium, live in a plan's service area, and enroll in a specific Medicare Advantage plan that offers this "rebate," with the amount varying by plan and location.
Here are some of the biggest Medicare mistakes to avoid:
Cost: Medicare monthly premiums can cost up to $175. On the other hand, the average cost of private health insurance for individuals is $477 per month. Depending on the plan and your care, it may also still have higher out-of-pocket costs than government programs.
Premium-Free Medicare Part A Based on Age
An individual who is receiving monthly Social Security or RRB benefits, at least 4 months prior to turning age 65, does not need to file a separate application to become entitled to premium-free Part A. In this case, the individual will get Part A automatically at age 65.
Medigap Premium Increases
Attained-Age plans typically experience premium increases as the policyholder gets older, while Issue-Age plans may experience premium increases due to inflation and other factors. Community-Rated plans may also experience premium increases due to inflation, but not due to age.
If you can't afford your Medicare premium, you likely qualify for financial help through Medicare Savings Programs (MSPs) or Extra Help, which cover premiums, deductibles, and drug costs for those with limited income and assets; start by visiting BenefitsCheckup.org or calling your State Health Insurance Assistance Program (SHIP) for personalized assistance. You can also get help from Medicaid or contact your State Medical Assistance office.
For 2026, the standard Medicare Part B premium is $202.90/month, an increase from 2025, with higher premiums for higher incomes (IRMAA), and the Part A deductible is $1,736, while Part D drug plan base costs start around $38.99/month, with potential surcharges for high earners. These costs are set by CMS and reflect rising healthcare expenses, impacting beneficiaries across Original Medicare (A & B) and Medicare Advantage/Part D plans.
Generally, you're first eligible to sign up for Part A and Part B starting 3 months before you turn 65 and ending 3 months after the month you turn 65. (You may be eligible for Medicare earlier, if you get disability benefits from Social Security or the Railroad Retirement Board.)
The ONLY reason to opt out of Medicare is if you want to 1) see a Medicare patient, 2) under private contract, 3) for covered services. All three of these must be true, or it is not worth your trouble to opt out.
Medicare Part B premiums are automatically deducted from Social Security checks, with the standard monthly amount for 2026 being $202.90, but this amount increases for higher-income earners. Most people get Part A for free, but if you pay premiums, they're also deducted. Part D (prescription drug) premiums can also be optionally deducted, while Part C (Medicare Advantage) premiums vary.
The "best" Medicare plan for seniors depends on individual needs, but top-rated providers for Medicare Advantage (Part C) in 2026 include Humana, UnitedHealthcare, Aetna, and Blue Cross Blue Shield (BCBS), offering nationwide coverage, large networks, $0 premium options, and extra benefits like dental/vision, while Medigap (Medicare Supplement) plans like Plan F provide comprehensive Original Medicare cost coverage. Key factors are your doctors, prescriptions, budget, and preference for network flexibility (MA) or broad coverage (Medigap).
Yes, you can switch back to Original Medicare from a Medicare Advantage plan during specific enrollment periods (like the Annual Enrollment Period: Oct 15–Dec 7, or the MA Open Enrollment: Jan 1–Mar 31) or via Special Enrollment Periods (SEPs) for life events, but you may need to buy a Medigap plan separately and face underwriting for it. Joining a Part D drug plan when you switch automatically disenrolls you from your Advantage plan, making the transition seamless for drug coverage.
Vermont, Utah and Minnesota topped the Commonwealth Fund's Medicare performance scorecard in 2025, whereas Kentucky, Mississippi and Louisiana struggled the most.
The Medicare "3-Day Rule" requires a beneficiary to have a qualifying 3-day inpatient hospital stay (admission day counts, discharge day doesn't) before Medicare will cover services in a Skilled Nursing Facility (SNF) for rehabilitation or skilled care, though this rule can be waived in certain Medicare Advantage plans or through specific Accountable Care Organization (ACO) initiatives. Time spent in observation or the Emergency Department doesn't count towards these 3 days, but new demonstration projects and waivers are emerging to offer more flexibility for patients needing SNF care.
There could be several reasons why Social Security stopped withholding your Medicare Part B premium. One common reason is that your income has exceeded the threshold for premium assistance. Another reason could be that there was a mistake or error in your records.
A few times a year, recipients of Supplemental Security Income (SSI) receive two payments in a month. But those double deposits aren't extra money. They're early payments for the following month.
