“Is that lifetime?” — a client asked me that about a Medicare penalty, hoping the answer was no. I hate this part of my job: the answer is yes. Most Medicare penalties are permanent. Here's how each one works and exactly how to never meet them.
Medicare’s late-enrollment penalties exist to keep people from waiting until they’re sick to sign up. Fair enough — but the rules are strict, the exceptions are specific, and the people who get caught are almost never freeloaders. They’re people who thought they were covered. Here are the three penalties, what they cost, and the safe path around each.
The Part B penalty: the expensive one
Skip Part B when you should have taken it, and your premium goes up 10% for every full 12 months you waited — permanently. Wait three years, pay 30% extra on every Part B premium for the rest of your life. The trap isn’t laziness; it’s bad assumptions. The three I hear most: “I have VA coverage, so I’m fine” (VA medical coverage does not count as employer coverage for this rule); “I’m on COBRA, so I’m covered” (COBRA does not protect you from the Part B penalty — this one catches smart people constantly); and “my employer plan continues into retirement” (retiree coverage generally doesn’t count either — only coverage from active employment does).
“I thought it was 185.” — small verbatim moment from a call about premiums, but it stands for something bigger: almost everything people 'know' about Medicare costs came from a neighbor, a commercial, or last year's numbers. Verify before you decide.
The Part D penalty: the sneaky one
Go 63+ days without drug coverage that’s at least as good as Medicare’s standard (“creditable” coverage), and you’ll pay 1% of the national base premium extra per month you waited — added to your drug plan premium forever. Waiting two years ≈ 24% extra, every month, for life. The healthy-person trap: “I take nothing, why pay for a drug plan?” Answer: because the cheapest plan in your county is your insurance against both the penalty and the prescription you don’t know about yet. One honest note: VA drug coverage does count as creditable — veterans with VA benefits can usually skip Part D penalty-free while that coverage lasts.
The Part A penalty: the rare one
Most people get Part A premium-free and can’t be penalized. If you don’t qualify for free Part A and enroll late, the premium rises 10% for twice the number of years you delayed — the only Medicare penalty that eventually expires.
The safe path, in one paragraph
Turning 65 and not working (or without real employer coverage)? Enroll during your 7-month window, full stop. Still working with genuine employer coverage from active employment? You can usually delay Part B and D penalty-free — but confirm your coverage counts before your birthday month, not after, because the burden of proof lands on you later. Leaving that employer coverage? Your 8-month Special Enrollment clock starts immediately — and remember, COBRA doesn’t stop it. When in doubt, ask: a ten-minute conversation is cheaper than a lifetime surcharge.
