Saving Access to Laboratory Services Act

The Saving Access to Laboratory Services Act (S 1000) modifies Medicare's payment rules for clinical laboratory tests to reduce administrative burden on providers. It introduces statistical sampling for "widely available" tests (defined as those costing under $1,000 per test and performed by over 100 labs) starting in 2026, requiring the government to use a representative sample of labs instead of collecting data from every lab. The bill also sets annual limits on payment increases: 2.5% for 2024-2025, 3.75% for 2026-2027, and 5% for 2028 onward for widely available tests, with a 5% cap for other tests. These changes affect Medicare-participating labs, including independent, hospital, and physician office laboratories that perform the covered tests.
