Medicare Part B helps cover the medical services you’re most likely to use, like doctor visits, outpatient care, lab tests, preventive screenings, and medications given in a clinical setting. It functions like traditional health insurance, but understanding how and when to enroll is key to avoiding penalties and unexpected costs.

From Doctor Visits to Diagnostic Tests
Part B pays for many of the essential services you need to stay healthy and manage conditions:
Doctor and specialist visits
Lab work and imaging (X-rays, MRIs, etc.)
Preventive services and screenings
Outpatient surgeries and rehab
Durable medical equipment (DME)
Certain medications administered in a doctor's office (like chemotherapy or infusion drugs)
Unlike Part A, which only applies when you’re admitted to a hospital, Part B is used for day-to-day healthcare needs. But it also comes with important cost-sharing rules you need to understand.
If you’re already receiving Social Security, you’ll be automatically enrolled in Medicare Part A at age 65. If not, or if you don’t qualify based on your own work history, you may be eligible through a spouse—or you can apply manually through Social Security. Premiums are based on work history. Not sure what your premiums should be?
For most people, the standard Medicare Part B premium in 2025 is $202.90 per month. If your income is above a certain level, you may pay more under IRMAA (Income-Related Monthly Adjustment Amount).
Here’s how Part B costs break down:
Monthly Premium: $202.90
Annual deductible: $283.00
Medicare pays: 80% of approved charges
You pay: 20% of approved charges
Excess Charge: Providers MAY charge up to 15% more than Medicarfe allows
Part B drugs: Medicare pays 80%, and you pay 20% for drugs administered in a doctor's office
Important: Part B has no out-of-pocket maximum (MOOP)—meaning your costs can continue to add up unless you have supplemental coverage.

If you’re enrolling in Medicare Part A and B without taking Social Security, applying for Extra Help, requesting an IRMAA adjustment, or submitting employer coverage info, you may need official forms to get started.
