Final answer:
Answer B is correct; Jennifer's Out-of-Pocket Maximum includes costs for prescription drugs and benefits not covered by Original Medicare, not plan premiums.
Step-by-step explanation:
When Jennifer is enrolling into a Medicare Advantage (MA) plan, what counts toward the Out-of-Pocket Maximum is a common question. Among the options provided, answer B is accurate: Jennifer's costs for prescription drugs and any benefits not covered by Original Medicare will count toward the Out-of-Pocket Maximum. This means that while Medicare-covered Part A and B services costs do apply towards this limit, things like plan premiums do not. It's important to note that the Out-of-Pocket Maximum is in place to help limit the total expenses a beneficiary has to pay in a calendar year.
