Medicare guidance
What the parts actually do, when you have to act, and how to bridge the years between an individual plan and your 65th birthday.
Overview
Medicare is federal health coverage for people 65 and older and for some younger people with qualifying disabilities. It is not one plan — it is four parts plus optional private coverage, and the decisions you make in your first enrollment window can follow you for life.
This page explains the structure in plain language and covers the part most people neglect: health insurance before Medicare. The years from 55 to 64 are the most expensive stretch of the individual market, and how you handle them determines what you can afford right up to your 65th birthday.
If you are approaching 65, start the conversation three to six months out. If you are bridging to 65, look at individual coverage and private plans.
The parts of Medicare
| Part | Covers | Notes |
|---|---|---|
| Part A | Inpatient hospital, skilled nursing, hospice | Usually premium-free with sufficient work history |
| Part B | Outpatient care, doctor visits, preventive services | Monthly premium; higher incomes pay an adjusted amount |
| Part C (Advantage) | Private plans bundling A, B, and usually D | Network-based, often with extra benefits and its own cost sharing |
| Part D | Prescription drugs | Private plans with formularies; late enrollment can carry a penalty |
| Medigap | Supplements Original Medicare cost sharing | Standardized letter plans; best pricing during your open window |
Enrollment windows that matter
Initial enrollment period
A seven-month window around your 65th birthday month. Missing it can mean lifetime premium penalties for Part B and Part D.
Special enrollment period
For people covered by an active employer group plan past 65 who then retire or lose that coverage.
Annual election period
The yearly window to change Advantage and Part D plans, since formularies and networks change every year.
Medigap open enrollment
A limited window after Part B starts during which supplement plans cannot use medical underwriting.
Working past 65
Whether to delay Part B depends on employer size and plan type. Getting this wrong is expensive; ask before deciding.
Bridging the years to 65
Price the individual market honestly
Age-banded premiums peak in the early 60s. This is where subsidy eligibility deserves careful attention.
Consider income planning
Because premium tax credits track modified adjusted gross income, retirement income timing can materially change your premium.
Keep pre-existing condition protection
This is the wrong life stage for a plan that excludes conditions — stay ACA-compliant.
Plan the handoff
We set the Medicare start date and cancel individual coverage so there is no double premium and no gap.
Turning 65 checklist
- Confirm whether you already have Part A through Social Security
- Decide on Part B timing based on any active employer coverage
- List your prescriptions before comparing Part D formularies
- List your doctors before comparing Advantage networks
- Understand the difference between Advantage and Original Medicare plus Medigap
- Note your Medigap open enrollment window on a calendar
- Cancel individual coverage effective the day Medicare begins
Advantage or Original Medicare plus Medigap?
There is no universal answer, and anyone who gives you one without asking about your doctors and prescriptions is selling rather than advising.
Original Medicare plus a Medigap plan and a Part D plan generally means higher fixed premiums, very predictable costs, and nationwide access to any provider accepting Medicare. It suits people who travel, split time between states, or want certainty.
Medicare Advantage generally means lower or no additional premium, network restrictions, and cost sharing as you use care, often with extra dental, vision, or fitness benefits. It suits people whose providers are all in one network locally.
The critical timing detail: Medigap pricing is most favorable during your open enrollment window. Choosing Advantage first and switching later can mean facing medical underwriting for a supplement.
