Still Working at 65? Medicare Timing Kit

Turning 65, or already past 65, and still covered by your job or your spouse's job? You may not need all of Medicare right away. But the rules for waiting are strict, and a wrong guess can mean a gap in coverage or a late penalty that usually lasts as long as you have that part of Medicare.

Whether you plan to keep working or retire soon, this kit walks you through the questions that decide your timing, then works out your own deadlines.

WHAT YOU GET

• Timing guide (PDF, 21 pages). The three questions that decide your timing (employer size, kind of coverage, HSA or Social Security), your choices now if you are staying at your job, Part A and Part B, the COBRA and retiree coverage trap, drug coverage, HSAs, Medigap timing, lowering higher-income premiums (IRMAA) after you stop working, what happens to your spouse's coverage (65 or older, or under 65), key dates, and what to do if HR gave you wrong information.
• Questions to ask HR, ready to send by email.
• 4 printable worksheets: my situation, my HR answers, my sign-up checklist, and my call notes.
• Timing calculator (Excel, opens in Google Sheets). Staying at your job? It shows your choices now. Retiring? Type in your dates and it works out your Part B window, drug plan window, Medigap window, your spouse's Medicare dates, your last safe month for HSA contributions, and how many days you have left.

WHAT IT COVERS

• Why employer size matters: 20 or more employees, the job plan pays first; fewer than 20, Medicare pays first
• Why COBRA, retiree and VA coverage do not count as job coverage for Part B timing
• The 8-month Part B window and Forms CMS-40B and CMS-L564, plus what to send if your employer will not sign
• Why any part of Medicare, even free Part A, ends HSA contributions, and how Part A can start up to 6 months back
• Creditable drug coverage and the 63-day rule
• When your one-time Medigap window starts
• If your spouse is on your job plan: a spouse 65 or older has their own Part B and Medigap dates, and a spouse under 65 can't get Medicare through you, so the guide covers COBRA and Marketplace timing for them

WHO IT IS FOR

People 64 and older who still have job coverage, whether they are staying at their job or planning to retire, plus spouses and family members helping them.
