HB 3699 requires Oklahoma's Medicaid agency (OHCA) to seek federal approval for a supplemental reimbursement rate for physician practices, community health workers, and nonprofits already enrolled in Oklahoma's patient-centered medical home program. This rate specifically supports pediatric care for children from birth to age four, covering wellness visits and funding interdisciplinary staff needed to implement team-based care aligned with Bright Futures screening guidelines (at 9, 18, and 30 months). Providers must verify ongoing participation in evidence-based pediatric practice models through annual documentation. The bill mandates OHCA to periodically review the rate during future Medicaid physician service rate adjustments and takes effect November 1, 2026.
