A few questions from this unit, with the answer and a full explanation. The complete bank is available when you start practising.

1. A state Medicaid program wants to offer home and community-based services (HCBS) to elderly individuals who would otherwise need nursing home placement. Under what federal authority can the state obtain approval for this program?

   • A
     The state must obtain approval from the state legislature only; no federal waiver is needed for HCBS.
   • B
     The state must apply for a Section 1115 research and demonstration waiver since HCBS is not permitted under regular Medicaid.
   • C
     The state may offer HCBS only if it also increases its FMAP contribution above the statutory minimum.
   • D
     The state may apply for a Section 1915(c) HCBS waiver, which allows states to provide home and community-based services as an alternative to institutional care.
     Correct answer
   Explanation

   Section 1915(c) of the Social Security Act authorizes states to apply for Home and Community-Based Services (HCBS) waivers. These waivers allow states to serve beneficiaries who would otherwise require institutional care (e.g., nursing home) in their homes or community settings, providing more person-centered care at potentially lower cost.

2. Which Medicare part covers outpatient prescription drugs purchased at a retail pharmacy?

   • A
     Medicare Part D
     Correct answer
   • B
     Medicare Part C
   • C
     Medigap
   • D
     Medicare Part B
   Explanation

   Medicare Part D is the voluntary outpatient prescription drug benefit. It is provided through private Prescription Drug Plans (PDPs) or Medicare Advantage Prescription Drug Plans (MA-PDs). It does NOT cover drugs administered in a physician's office, which are covered under Part B.

3. Which federal agency oversees Medicaid at the national level?

   • A
     The Centers for Medicare & Medicaid Services (CMS), within the U.S. Department of Health and Human Services (HHS)
     Correct answer
   • B
     The Social Security Administration (SSA), which determines eligibility for Medicaid and Medicare
   • C
     The Health Resources and Services Administration (HRSA), which oversees all federal health programs
   • D
     The Department of Defense (DoD), which administers Medicare and Medicaid for federal employees
   Explanation

   CMS (Centers for Medicare & Medicaid Services) is the HHS agency responsible for overseeing Medicaid at the national level. CMS sets federal Medicaid requirements, reviews and approves state Medicaid plans and waivers, and monitors state compliance with federal rules. Key takeaway: CMS (within HHS) is the federal Medicaid oversight agency.
