This is a fixed, preset amount you must pay for health care and prescription drugs before Medicare Parts A and B, your prescription drug plan, or other insurance steps in to pay.  Normally, deductibles are applicable with Medicare Parts A, B, and D, though they can apply to some Part C and Medigap plans. Deductibles can vary between Medicare prescription drug plans and some Medicare prescription drug plans don’t have a deductible. The Part B deductible is $183 per year in 2017 and after your deductible is met, you typically pay 20% of the Medicare-approved amount for most doctor services, outpatient therapy, and durable medical equipment.
