Which health insurance do I need when I retire?

The health insurance you need when you retire depends entirely on your age at retirement, as the American healthcare system divides retirees into two distinct pathways: Medicare for those 65 and older, and bridge insurance for early retirees under 65.

If You Retire at Age 65 or Older

If you are 65 or older, Medicare is your primary health insurance foundation.  Original Medicare, however, has gaps (such as no coverage for most prescription drugs, and no out-of-pocket maximums), so you must choose one of two paths to round out your coverage:

Path 1: Original Medicare + Add-ons (The "A la Carte" Route)

• Medicare Part A (Hospital Insurance): Covers inpatient hospital stays and skilled nursing. It is $0/month for most people who have worked at least 10 years.
• Medicare Part B (Medical Insurance): Covers doctor visits, outpatient care, and preventive services. This requires a monthly premium (standard premium is adjusted annually and increases if your income is high via IRMAA adjustments).
• Medicare Part D (Prescription Drugs): Standalone plans run by private insurance companies to cover your medications.
• Medigap (Medicare Supplement): Private policies that pay for the deductibles, coinsurance, and copays left behind by Parts A and B.

Path 2: Medicare Part C (The "All-in-One" Medicare Advantage Route), a.k.a. “MEDICARE DISADVANTAGE”

• Medicare Advantage: An alternative to Original Medicare. Private insurance companies package Parts A, B, and usually D into a single plan (often structured as an HMO or PPO).
• Many of these plans offer a $0 additional monthly premium (though you still must pay your standard Part B premium) and add extra perks like vision, dental, and fitness club memberships. But, you are restricted to a specific network of doctors. So if you’re hoping to get one of the best specialists, you may be out of luck.

If You Retire Early (Under Age 65)

If you retire before age 65, you must find a "bridge" solution to cover you until Medicare kicks in. Your best options include:

Option	How It Works	Best For	Hidden Costs / Downsides
Spouse’s Workplace Plan	Joining your spouse’s active employer-sponsored health plan as a dependent.	Anyone with an employed spouse.	Dependent premiums can sometimes be high.
ACA Marketplace Plans	Buying an individual policy on the Health Insurance Marketplace. Retiring counts as a "Qualifying Life Event" so you can enroll immediately.	Retirees whose post-retirement income drops.	Premiums increase with age, but you may qualify for massive tax subsidies based on your income (not your savings).
COBRA Continuation	Legally extending your exact workplace insurance plan for up to 18 months.	People who retire at age 63.5 or those undergoing active medical treatment who cannot switch doctor networks.	Extreme wealth-degrading trap: You must pay 102% of the premium out of pocket, losing the employer subsidy.
Retiree Health Coverage	Rare benefits provided by specific companies, unions, or government entities (like FEHB for federal workers).	Former public servants or union employees.	Rules vary significantly; it may become secondary to Medicare once you turn 65.

    Critical Order of Operations & Penalties

1. Watch the Calendar: If you do not enroll in Medicare Part B and Part D when you first become eligible at 65 (and you don't have "creditable" employer coverage), you face a permanent lifetime late-enrollment penalty added to your monthly premiums for the rest of your life.
2. Income Timing: If you use an ACA Marketplace plan early in retirement, manage your Traditional IRA/401(k) withdrawals carefully. Boosting your taxable income too high will wipe out your health insurance subsidies, suddenly costing you thousands extra in premiums.
