HB3359 would amend Oklahoma’s Medicaid biomarker testing law to make coverage discretionary rather than mandatory. Under the bill, the state Medicaid program and its contracted entities may cover biomarker testing for diagnosis, treatment, management, or monitoring of a disease or condition when supported by medical and scientific evidence, including FDA labeling, CMS coverage determinations, and nationally recognized clinical guidelines.
The bill also preserves procedural requirements tied to prior authorization and member access. If prior authorization is used, the contracted entity must act within 72 hours for non-urgent requests or 24 hours for urgent requests, and members and providers must have a clear online process to request exceptions to coverage policies. The bill would take effect November 1, 2026.
Impact
HB3359 would change Section 4003 of Title 56 by shifting biomarker testing coverage in Medicaid from a mandatory requirement to a permissive one. This could reduce the scope of enforceable coverage obligations for the Oklahoma Medicaid program and its managed care or contracted entities, while still allowing coverage under evidence-based criteria and preserving prior authorization timelines and exception procedures.
Sentiment
No committee transcript or recorded vote information is available, so the overall sentiment cannot be measured from debate or roll call data. Based on the bill text alone, the measure appears to reflect a policy preference for greater discretion in Medicaid coverage decisions while retaining patient-access safeguards.
Contention
The main point of contention is likely whether biomarker testing should remain a required Medicaid benefit or be left to the discretion of the program and its contractors. Supporters may favor flexibility and cost control, while opponents may argue that making coverage discretionary could limit access to medically necessary precision medicine tests for patients with serious conditions. The prior authorization and exception-process provisions suggest an attempt to balance administrative control with access concerns.
