- An annual wellness visit and preventive services, like flu shots and mammograms
- Lab services, like blood tests
- X-rays and some other diagnostic tests

- Physical therapy, occupational therapy and speech-language pathology services
- Diabetes screenings, diabetes education and certain diabetes supplies
- Mental health care
- Durable medical equipment for use at home, like wheelchairs and walkers
- Ambulatory surgery center services
- Ambulance and emergency room services
Part B Costs
- Premium
- You will pay a monthly premium, currently $148.50.
- Your premium is prorated by your income. If your reported income from 2 years prior is above the designated level, you will pay a higher premium, as much as $504.90.
- You are required to have Part B if you are 65 and don’t have health coverage through another source.
- If you have Medicare and Medi-Cal, Medi-Cal pays your premium.
- Deductible
- You have an annual deductible, which is $203 currently
- Coinsurance
- You generally pay 20% of the Medicare-approved amount for most covered services after you pay the deductible, with no annual out-of-pocket maximum. Medicare pays the remaining 80%.
Enroll in Medicare Part B on time to avoid late enrollment penalties
The Part B penalty is 10% of the monthly premium amount for each full 12-month period enrollment is delayed.
You pay the penalty in addition to your premium for as long as you have Medicare Part B, unless you qualify for a Special Election Period or have a qualified plan.
For example
If you delayed enrollment for 3 years, you will pay an additional 30% of the Part B premium as long as you have Part B.
