Medicare

Basics of Medicare

  • Created by the Social Security Act in 1965
  • Originally health insurance to those 65 years of age and older
  • Expanded to include certain disabilities (20% now below age 65)

Medicare consists of four parts:

  • Part A: Hospital Insurance
  • Part B: “Medical” Insurance (physician visits and outpatient care)
  • Part C: Private supplemental care (Medicare plus Choice, now Medicare Advantage)
  • Part D: Prescription Drug Coverage

Medicare Part A

  • Automatic enrollment for anyone 65 and older who worked over their lifetime
  • Financed with combination of payroll tax (current workers) and cost-sharing (deductibles, etc.)
  • Funds exist as part of “Federal Hospital Insurance Trust Fund”…can’t finance through debt

Part A benefit structure:

  • Very good for short inpatient stays
  • Very bad for major problems with long stays
  • Doesn’t cover nursing home care beyond 30 days

Medicare Part B

  • Voluntary, but almost everyone enrolls
  • Requires monthly premium ($144 in 2020)
  • Small deductible and 20% co-insurance

Medicare Part C

  • Private insurance provision of Medicare benefits
  • Formally created under Balanced Budget Act in 1997 (existed informally before)
  • Heavily revised in Medicare Modernization Act in 2003
  • Medicare pays insurers a risk-adjusted amount to enroll a given beneficiary
  • Broader benefits than Part A and B, often with $0 additional premiums, but restrictive networks

Medicare Part D

  • Created under the Medicare Modernization Act in 2003
  • Private insurance for prescription drugs
  • Insurers receive payments from Medicare to enroll a given beneificiary (much like Part C)
  • Many insurers offer a combined Part C+D plan

Privatization of Medicare

  • Medicare Advantage (both Parts C and D) has been well-received and generally thought to be a success story for Medicare benefits
  • Accounts for nearly half of total Medicare enrollees
  • Some early difficulties with adverse selection and risk-adjustment
  • Still slightly sicker people staying in traditional Medicare
  • Could be a big part of any future “Medicare-for-all” type program

Medicare payments for inpatient services

  • Prospective payment system
  • Begin with two “base” rates:
    • Operating base payment rates, $5,797 in 2020
    • Capital base payment rates, $462 in 2020
  • Adjustments:
    • Diagnosis Related Group (higher adjustments for more complicated things)
    • Academic Medical Center
    • Disproportionate Share

More recently:

  • Introduction of quality incentives through…
    • Value Based Purchasing (VBP)
    • Hospital Readmission Reduction Program (HRRP)
    • Quality Payment Program for physicians (choose between merit based payment system or advanced alternative payment models)
  • Introduction of capitated payments through…
    • Bundled Payments
    • Accountable Care Organizations

Medicaid

Background on Medicaid

  • Also created by the Social Security Act in 1965
  • Originally provided health insurance to people receiving “Aid to Families with Dependent Children”, mainly extremely poor families
  • Expanded over time with different rules by state
  • Huge program: about 40% of births are covered by Medicaid/CHIP

ACA and Medicaid Expansion

  • Big part of ACA was Medicaid expansion
  • Originally mandatory but made voluntary by Supreme Court
  • Expansion covers all adults (with or without children) below age 65 and with incomes below 138% of the federal poverty line ($35,535 for family of 4 in 2020)

Medicaid Funding

  • Paid for by states and federal funding
  • State funding is matched by federal funds, and the match amount depends on the state’s per capita income
  • Incentivizes services to be provided by Medicaid that historically may not be

Medicaid Benefits

  • Pretty generous coverage
  • Low to no copayments, deductibles, co-insurance
  • Usually covers dental, vision, hospitals, and physician services
  • Covers long term care (unlike Medicare), with about 40% of all long term care paid for by Medicaid

Medicaid Payments

  • Works similarly to Medicare with a base rate plus adjustments
  • Base rates vary by state Medicaid agencies
  • Adjustments (or supplemental payments) consist of:
    • Disproportionate share adjustments
    • Other (non-DSH) adjustments
    • Account for a little less than half of total Medicaid payments on average

Privatization in Medicaid

  • Increasing reliance on Medicaid managed care (80% of Medicaid enrollees)
  • States outsource Medicaid benefits to private insurers, with oversight

Veterans Administration

  • “Integrated” healthcare provider and insurer
  • Comprehensive medical services without out-of-pocket payments or insurance claims
  • Operates its own healthcare facilities and employs healthcare providers directly, covering the costs of care provided to veterans
  • Funding for VA healthcare comes from the federal government’s budget allocated to the VA, which covers staffing, facilities, equipment, medications, and other necessary resources for delivering healthcare services to veterans
