HEALTH INSURANCE & MEDICARE

Choose the coverage. Know the real cost. Don’t miss the handoff.

Health coverage gets expensive when the calendar, the network, or the income rules change before the plan does. Start with the transition you are actually facing.

What changed?

The same household can move through all four of these paths within a few years. They are decision states, not permanent labels.

THE FIRST RULE OF PLAN COMPARISON

Premium is not the price of the plan.

First eliminate plans that fail your must-have doctors, hospitals, prescriptions or access rules. Then compare the surviving plans by annual premium plus the medical costs you are likely to pay.

ILLUSTRATIVE PLAN A $360/mo premium Lower premium · higher member cost exposure
ILLUSTRATIVE PLAN B $540/mo premium Higher premium · lower member cost exposure
Plan A$5,120$4,320 premiums + $800 expected covered care
Plan B$6,880$6,480 premiums + $400 expected covered care

With light use, the lower-premium plan wins this simplified example.

Plan A$6,820$4,320 premiums + $2,500 expected covered care
Plan B$7,880$6,480 premiums + $1,400 expected covered care

The premium gap narrows once you actually use the coverage.

Plan A$12,820$4,320 premiums + $8,500 illustrative in-network maximum
Plan B$10,980$6,480 premiums + $4,500 illustrative in-network maximum

In a very high-cost year, the higher-premium plan can become the cheaper risk-transfer choice.

Illustrative teaching example only. Real plans differ in networks, covered services, copays, coinsurance, deductibles, out-of-pocket limits, employer contributions and tax treatment. Out-of-network and noncovered care may not count toward the in-network maximum.

RETIRING BEFORE MEDICARE

The gap to 65 is a coverage problem and an income-planning problem.

If employer coverage ends before Medicare begins, compare the coverage route and the income consequences together.

1Spouse or employer coverageOften the cleanest bridge when available. Compare the actual dependent premium and network.
2COBRACan preserve the same employer plan temporarily, but usually shifts much more of the premium to you.

THE MEDICARE HANDOFF

Four decisions happen close together. They are not the same decision.

Use the walkthrough to see the order. The correct enrollment timing depends on your actual coverage and work situation.

WATCH THE HANDOFF

Confirm when Part B should start

If you are still working and covered by current employment, the Part B timing rules can differ from someone who is retiring at 65. COBRA is not current-employment coverage.

ON MEDICARE

IRMAA can turn an income decision into a Medicare-premium decision two years later.

The tax year, filing status and Medicare MAGI determine the income-related step. For 2026 premiums, Social Security generally uses 2024 tax information.

2024Income happensAGI + tax-exempt interest for Medicare MAGI.
SSA LOOKBACKTax data travels forwardGenerally two years.
2026Medicare premium changesPart B and Part D may include IRMAA.
2026 · SINGLE FILER $109,000 or less of 2024 Medicare MAGI: no IRMAA.
FIRST IRMAA STEP $1,148.40/yr Part B + Part D surcharge if both apply for all 12 months.

For 2026, the first single-filer IRMAA band begins above $109,000 of 2024 Medicare MAGI; the corresponding joint threshold is above $218,000. The first monthly adjustment is $81.20 for Part B plus $14.50 for Part D. Each covered spouse pays their own surcharge.
