Turning 65 brings a flood of mail, ads and sales calls, and a handful of real deadlines that can cost you money every month for life if you miss them. Medicare Made Simple explains exactly what to do, when to do it, and how to choose coverage that fits your health, doctors and budget.

You will learn what Parts A, B, C and D and Medigap actually cover, and what they cost in 2026: the $202.90 Part B premium, the $1,736 Part A deductible, the full IRMAA income brackets, and the new $2,100 yearly cap on Part D drug costs. You will find your personal seven-month sign-up window to the month, see exactly when coverage starts, and learn how to avoid all three late enrollment penalties, with worked examples showing the math.

Still working at 65? A full chapter covers employer size, COBRA and retiree coverage traps, coverage through a working spouse, the forms you need when you retire (CMS-40B and CMS-L564), and the six-month HSA look-back that catches many people by surprise.

Then you get an honest, side-by-side comparison of Original Medicare with Medigap versus Medicare Advantage, including networks, prior authorization, out-of-pocket limits and the one-time Medigap window that makes your first choice so important. You will learn to use Medicare Plan Finder, apply for Extra Help and Medicare Savings Programs, appeal IRMAA after retirement, and spot scams and pushy marketing.

It ends with six worked real-world situations, an official sources guide and a month-by-month plan from age 64 through your first year. Educational guide; not legal, financial or medical advice.

Read a sample

Situation: Tom retired at 66 in March 2026 from a large company. He had delayed Part B correctly while working. HR offered COBRA for 18 months and he took it, planning to switch to Medicare when COBRA ran out. The problem: His 8-month Part B SEP started in April 2026, the month after his employment ended, and runs through November 2026. COBRA does not extend it. If he waits until COBRA ends in late 2027, he will have missed the SEP, will have to wait for the General Enrollment Period, may face a gap, and will likely owe a Part B penalty. What he does: He enrolls in Part B no later than November 2026 (ideally right away) using CMS-40B and CMS-L564. Once he has Medicare, COBRA would generally pay second, and his COBRA coverage may end. He drops COBRA, chooses Medigap Plan G during his Medigap Open Enrollment Period, and adds a Part D plan. Since COBRA drug coverage may or may not be creditable, he checks his notice and makes sure he does not go 63 days without creditable drug coverage. Key lesson: The 8-month clock starts when work ends, not when COBRA ends.
