Medicare can help pay for health care, but enrolling does not remove every expense or decision. Three checks can help you prepare: what you will pay, what your coverage includes and when you must act.
1. Premium-free does not mean cost-free
Most people qualify for Part A without a monthly premium based on an eligible work record. Part B generally has a premium. In 2026, the standard Part B premium is $202.90 per month and the annual deductible is $283; individual premiums can be higher because of income or a penalty.
You may also owe deductibles, copayments or coinsurance when receiving care. Separate Medicare plan and Medigap premiums depend on the policy. A Medicare Advantage plan advertising a $0 additional premium does not make every service free or automatically eliminate the Part B premium.
2. Identify the coverage you actually have
| Coverage | Important distinction |
|---|---|
| Original Medicare | Parts A and B cover qualifying hospital and medical services; they do not cover everything. |
| Medicare Advantage | A private way to receive Medicare benefits, with plan-specific networks and costs. |
| Medigap | Helps with specified Original Medicare expenses; it does not pay Medicare Advantage cost sharing. |
| Part D | Prescription insurance that can be separate or included in a Medicare Advantage plan. |
Routine dental care, routine eyewear and hearing aids generally are not Original Medicare benefits, although specific medical exceptions exist. Long-term custodial care also has different rules. Do not assume an extra benefit or spending allowance is available to every enrollee.
3. Enrollment is not one deadline for everything
The usual initial Medicare enrollment period spans seven months around your 65th birthday. Disability, ALS and ESRD can provide earlier eligibility. Qualifying current-employment coverage may allow a later enrollment opportunity; COBRA and retiree insurance do not provide identical protection.
Annual Medicare plan changes and Medigap purchase rights follow separate rules. Choosing Medicare Advantage does not erase a Part B late-enrollment penalty. Confirm your coverage dates and applicable period with Social Security, Medicare or the plan before changing existing insurance.
