Health Policy & Advocacy

Medicare is federal insurance for people 65 and older or disabled; Medicaid is a joint federal–state program for low-income people; bills become law through Congress and the President.

01 · What it isPart A hospital; Part B clinicians

Medicare Part A covers inpatient hospital care, skilled nursing facility care, hospice and home health; Part B covers services from physicians and other providers such as NPs, outpatient care, durable medical equipment and preventive services.

02 · Defined byMedicare: age 65+, disability, ESRD or ALS

Medicare is federal health insurance for people 65 and older and for younger people with end-stage renal disease, ALS, or a disability after 24 months of Social Security disability benefits.

03 · What it isMedicaid: joint federal–state, low income

Medicaid is a joint federal–state program for certain low-income people and covers nursing facility (long-term) care, which Medicare does not; dual-eligible patients have both, with Medicaid helping pay Medicare costs.

The rules

Know these

ACA: pre-existing conditions, age-26 dependents, EHBsUnder the ACA, plans cannot reject, charge more or deny essential health benefits for pre-existing conditions; young adults may stay on a parent's plan until 26; Marketplace plans cover 10 essential health benefits.

President has 10 days; pocket veto standsThe President has 10 days (Sundays excepted) to sign or veto a bill; if Congress adjourns and the bill is left unsigned, it dies by pocket veto, which Congress cannot override.

State law sets NP scope of practiceState law sets NP practice authority; AANP classes states as full, reduced or restricted practice, and full practice — recommended by the National Academy of Medicine and NCSBN — is a core advocacy goal.

Nurses have an ethical duty to shape policyThe ANA Code makes policy work an ethical duty: Provision 7 covers nursing, health and social policy development; Provision 9 calls nurses and their organizations to advance legislation promoting social justice and health equity.

SNF coverage needs a 3-day inpatient stayMedicare Part A pays for skilled nursing facility care only after a medically necessary inpatient stay of at least 3 consecutive days; time under observation status does not count.

What it is

Core idea

Part C Medicare Advantage; Part D drugs must knowPart C (Medicare Advantage) is a Medicare-approved private plan that bundles Parts A and B and usually D, often with networks and prior authorization; Part D covers outpatient prescription drugs through private plans.

Diagnosis & monitoring

Work-up

ACA Medicaid expansion to 138% FPLThe ACA expanded Medicaid to nearly all adults with incomes up to 138% of the federal poverty level with enhanced federal matching; expansion is a state option, adopted by 41 states including DC.

Management

Orders

Bill → committee → both chambers → President must knowA bill goes to committee, then must pass the House and Senate in identical form; the President signs or vetoes it, and Congress can override a veto by a two-thirds vote in each chamber.

Agencies turn laws into regulationsCongress delegates rulemaking to agencies: a proposed rule appears in the Federal Register, the public comments (normally at least 30 days), and the agency issues a final rule — commenting is direct advocacy.

Reference

Show 5 reference facts

Medicare does not pay for long-term custodial care (help with activities of daily living); patients pay privately or through Medicaid if eligible.

The 2025 federal reconciliation law requires states to condition Medicaid eligibility for ACA expansion adults (and some 1115-waiver enrollees) on work requirements starting January 1, 2027.

Medigap is private supplemental insurance that helps pay Original Medicare cost-sharing such as the 20% Part B coinsurance; Medicare Advantage plans instead carry a yearly out-of-pocket limit.

Revenue (tax) bills must originate in the House; each chamber passes a bill by simple majority (218 of 435 in the House, 51 of 100 in the Senate), and a conference committee reconciles differences.

In full-practice states NPs evaluate, diagnose, order and interpret tests, and prescribe, including controlled substances, under the board of nursing alone; reduced and restricted states require career-long collaboration or supervision.

Pearl

Medicare is for age and disability, Medicaid for low income — and many patients qualify for both.
