EVV by state
Medicaid EVV rules, state by state
Electronic Visit Verification is federal law: the 21st Century Cures Act required every state to mandate EVV for Medicaid personal-care services by January 2020 and home-health services by January 2023. What differs by state is everything that decides whether your claim pays — the aggregator, the codes, the thresholds, and the enforcement dates.
