ISO-11179 Definition
Medicare Shared Savings Program — the CMS program established by the Affordable Care Act that enables Accountable Care Organizations to share in savings generated when they deliver high-quality coordinated care to Medicare fee-for-service beneficiaries at costs below a risk-adjusted expenditure benchmark. MSSP is the largest federal value based care initiative, with hundreds of ACO participants collectively serving millions of Medicare beneficiaries across multiple participation tracks with varying risk levels. Basic track participants begin with upside-only savings sharing before progressing to two-sided risk while Enhanced track participants accept immediate downside risk in exchange for higher savings sharing rates.
MSSP quality reporting requirements include HEDIS clinical measures and CAHPS patient experience surveys, with minimum attainment thresholds that must be met before any shared savings distribution is received. Healthcare data teams build MSSP analytics pipelines that replicate CMS attribution methodology, calculate risk-adjusted benchmark expenditure, measure quality performance across required domains, project shared savings eligibility throughout the performance year, and produce CMS quality reporting submissions.

Why This Term Matters
Quality measure data determines how payers and providers are rated and reimbursed under CMS Stars, HEDIS, and value-based care contracts. Data engineers who understand quality terminology build measure calculation pipelines that correctly attribute patients, apply denominator exclusions, and flag documentation gaps before submission deadlines. Incorrect quality data directly affects star ratings, pay-for-performance bonuses, and Medicare Advantage plan bids.
