Medicare Parts A and B: What They Cover and What Comes Next
· King Life Insurance
MEDICARE BASICS
Parts A and B create the foundation. Your coverage path comes next.
Original Medicare consists of Part A hospital insurance and Part B medical insurance. Understanding what each part covers—and when to enroll—makes the later choice between Original Medicare with added coverage and Medicare Advantage much easier.

Medicare Part A: hospital insurance
Part A helps cover inpatient hospital care, skilled nursing facility care after a qualifying inpatient stay, hospice care, and certain home health services. Part A is not a blanket “everything in a hospital” benefit: outpatient services, observation status, deductibles, coinsurance, and benefit-period rules can still affect what you pay.
Questions to ask about Part A
- Will I qualify for premium-free Part A based on my or my spouse’s work history?
- Could starting Part A affect my ability to contribute to a Health Savings Account?
- Do I understand the inpatient deductible and benefit-period structure?
- How would employer, retiree, VA, TRICARE, or other coverage coordinate with Medicare?
Medicare Part B: medical insurance
Part B helps cover services from doctors and other health-care providers, outpatient care, durable medical equipment, many preventive services, and certain home health services. Most people pay a monthly Part B premium. Under Original Medicare, covered Part B services commonly involve a deductible and coinsurance, and Original Medicare alone has no built-in annual out-of-pocket maximum.
Questions to ask about Part B
- When does my Initial Enrollment Period begin and end?
- If I am working past 65, is my coverage based on my or my spouse’s current employment?
- When will employer coverage end, and when should Part B begin to avoid a gap?
- Could an income-related adjustment affect my Part B premium?
After A and B: choose how to receive coverage
| Original Medicare path | Medicare Advantage path |
|---|---|
| Part A and Part B remain your primary federal coverage. | A private Medicare-approved plan administers your Part A and Part B benefits. |
| You may add a standalone Part D drug plan. | Most plans include Part D; these are often called MAPD plans. |
| You may be able to add a Medicare Supplement policy to help with Original Medicare cost sharing. | A Medicare Supplement policy cannot be used to pay Medicare Advantage cost sharing. |
| You can generally use any provider nationwide that accepts Medicare. | Provider networks, service areas, referrals, and prior authorization may apply. |
