CMS guidelines apply to which Medicare product types?

• A. MA and PDP plans
• B. PDP plans
• C. Only MA plans
• D. Dental plans

Answer: (A)

CMS guidelines govern how plans that deliver Medicare benefits operate, covering how they market, enroll, design benefits, and protect beneficiaries. These rules apply to both Medicare Advantage and Part D prescription drug plans because CMS oversees Medicare through these private plan types and sets rules for both medical coverage and drug coverage. Medicare Advantage plans bundle Part A and Part B benefits and may add extras, while Part D plans provide prescription drug coverage as a standalone option. Both are directly regulated by CMS, including contract oversight, formulary processes, and beneficiary protections. Dental plans aren’t Medicare product types under this framework, so they’re not included in the range of plans governed together by these guidelines.
