The Gap Between Working and Medicare

Medicare eligibility begins at 65. If you retire before 65 — by choice or otherwise — you need to bridge the healthcare gap. Options include COBRA continuation coverage (expensive), marketplace insurance, or a spouse's employer plan. This gap can cost $500–$1,500+/month and is the #1 reason early retirement is financially complicated.

Medicare: The Four Parts

PartWhat It CoversCost
Part AHospital stays, skilled nursing, some home healthUsually free (if you paid Medicare taxes for 10+ years)
Part BDoctor visits, outpatient care, preventive services~$185/month (2025, income-based)
Part C (Medicare Advantage)Private plan covering A+B, often D; may include extrasVaries by plan
Part DPrescription drugsVaries by plan (~$20–$100+/month)

What Medicare Doesn't Cover

Significant gaps that catch retirees off guard:

  • Long-term care: Nursing home, assisted living, in-home caregivers — Medicare covers very limited skilled nursing, not ongoing custodial care
  • Dental, vision, hearing: Standard Medicare does not cover routine dental, glasses, or hearing aids (some Advantage plans do)
  • Most care outside the US: International travel coverage is minimal
  • Deductibles and copays: Medicare has no out-of-pocket maximum — Medigap (supplemental) insurance fills this gap

The HSA Connection

If you're on KC's HDHP and contributing to an HSA, every dollar in that account can be used tax-free for Medicare premiums, deductibles, copays, and out-of-pocket costs in retirement. An HSA used this way is one of the most tax-efficient retirement savings vehicles available — and the savings don't expire.

Enrollment deadlines matter. You must enroll in Medicare Part B during your Initial Enrollment Period (3 months before to 3 months after your 65th birthday) or face a permanent premium penalty. Don't miss it.

Healthcare Cost Estimates in Retirement

Fidelity estimates the average 65-year-old couple will need approximately $315,000 saved just for healthcare costs in retirement (2023 estimate). This includes premiums, copays, and out-of-pocket costs — but not long-term care. Planning for healthcare as a distinct retirement budget line item is essential.
