Core benefits that must be covered in all 10 standard Medicare supplement policies include which of the following?

The core benefits that must be covered in all 10 standard Medicare supplement policies include certain essential aspects of Medicare coverage that enhance the protection for policyholders. Specifically, these core benefits encompass:

• The coinsurance for Medicare Part A, which is the amount a beneficiary must pay for hospital stays after the initial benefit period.

• Coverage for the Part B coinsurance or copayment, which is the patient's share of costs for outpatient care after they have met their Part B deductible.

• The Medicare Part B deductible itself, which is the amount beneficiaries must pay out-of-pocket before Medicare begins to pay.

Considering that these three essential components are foundational to the Medicare supplement policies, the correct answer accurately reflects that all of these core elements are included in the policies. This comprehensive coverage ensures that beneficiaries have minimal financial liability when accessing healthcare services covered by Medicare, thereby reducing out-of-pocket expenses. This is why the answer encompasses all of these benefits as mandatory for standard Medicare supplement policies.
