Key takeaways: Sign up for Medicare Part A and Part B through Social Security. Compare Part D or Medicare Advantage plans through Medicare.gov after confirming your Medicare eligibility and effective dates. Do not delay enrollment simply because you feel healthy—late enrollment can create coverage gaps and penalties.
If you just lost job-based health insurance, your next deadline depends on whether you are Medicare-eligible. Marketplace, Medicare, COBRA, spouse coverage, Medicaid, and CHIP use different rules.
How do I sign up for Medicare?
Direct answer: Sign up for Medicare Part A and Part B through the Social Security Administration. If you are not automatically enrolled, you can apply online at SSA.gov, call Social Security at 800-772-1213, or make an appointment.
For most people becoming eligible at age 65, the Initial Enrollment Period lasts seven months: the three months before the month you turn 65, your birthday month, and the three months after it. Applying before your birthday month can help prevent a delayed start.
- Confirm whether Social Security will enroll you automatically.
- Confirm the dates of your Initial Enrollment Period.
- Decide whether active employer coverage allows you to delay Part B safely.
- Apply for Part A and Part B through Social Security.
- After confirming your Medicare effective dates, compare how you will receive coverage: Original Medicare, Medicare Advantage, Medigap, and Part D.
Working after age 65 requires a separate review
Active employer group coverage may let you delay Part B, but employer size, the type of coverage, HSA contributions, and whether the coverage is based on current employment can change the answer. COBRA and retiree coverage do not extend the eight-month Part B Special Enrollment Period tied to active employment.
How do I sign up for Medicare Part D?
Direct answer: Once you have Medicare Part A or Part B, compare Medicare drug plans available in your area at Medicare.gov. You can enroll through Medicare Plan Finder, call 1-800-MEDICARE, contact the plan, or work with a licensed broker.
Part D is offered by private insurance companies that contract with Medicare. You can receive drug coverage through a standalone Part D plan with Original Medicare or through many Medicare Advantage plans that include drug coverage.
Before enrolling, gather:
- Every prescription name, dosage, quantity, and refill frequency.
- Your preferred retail and mail-order pharmacies.
- Any prior authorization, step therapy, or quantity-limit concerns.
- Your notice showing whether existing drug coverage is creditable.
Do not choose Part D by premium alone. Formularies, drug tiers, pharmacies, deductibles, and yearly out-of-pocket costs can make a lower-premium plan more expensive for your medication list.
What happens if I do not sign up for Medicare?
Direct answer: If you delay Medicare without qualifying coverage or a Special Enrollment Period, you may have a gap in coverage and late-enrollment penalties. The result depends on which part of Medicare you delayed.
- Part A: If you must pay a Part A premium and enroll late, the premium can increase by 10 percent. The penalty generally lasts twice the number of years you delayed.
- Part B: The premium can increase by 10 percent for each full 12-month period you could have had Part B but did not. The penalty generally continues for as long as you have Part B.
- Part D: A penalty may apply after 63 or more consecutive days without Part D or other creditable prescription coverage. Medicare calculates it using one percent of the national base beneficiary premium for each full uncovered month.
- Coverage timing: If no Special Enrollment Period applies, you may have to use the Medicare General Enrollment Period from January 1 through March 31. Coverage generally starts the month after enrollment.
These penalties are not automatic in every delayed-enrollment case. Active-employment coverage, Extra Help, Medicare Savings Programs, and certain exceptional circumstances can change the result.
I just lost my job and need health insurance. What should I do?
Direct answer: First confirm the exact date your employer coverage ends. If you are under 65, compare an ACA Marketplace plan, COBRA, a spouse's employer plan, and Medicaid or CHIP eligibility. Losing job-based coverage generally creates a 60-day Marketplace Special Enrollment Period.
If you are under 65
Marketplace coverage can generally begin the first day of the month after job-based insurance ends. Your potential premium tax credit is based on estimated household income for the full calendar year—not only your income after the job loss. Keep the coverage-loss notice in case HealthCare.gov requests documentation.

If you are Medicare-eligible
Loss of active-employment coverage can start an eight-month Special Enrollment Period for Part B. That window begins when employment or the group health plan ends, whichever happens first. Choosing COBRA does not extend it. Medicare Advantage and Part D enrollment use separate, usually shorter deadlines, so review the dates immediately.
