Coverage is the start, not the finish line.
State laws now require coverage of biomarker testing in half the country. The next step is making sure covered testing reaches patients in time.
25 states have passed coverage laws.
These states have enacted laws requiring health plans to cover biomarker testing. Details vary, including which plans the law applies to.

Coverage is the start
A coverage law makes testing payable. It doesn’t make sure the test is ordered, the sample is usable, or the results arrive before treatment. Payers and policymakers can help close the rest of the gap.
- Cover testing that matches current clinical guidelines, including comprehensive panels and blood-based tests.
- Make prior authorization fast or unnecessary for guideline-recommended testing, so it doesn’t delay treatment.
- Cover repeat testing when cancer progresses or the first sample can’t be read.
- Hold implementation to account: measure whether testing actually reaches patients after a law passes.
