HB 1974 would require Oklahoma's Medicare program to cover annual preventative diagnostic screenings at no cost for eligible seniors. It specifies coverage for heart health tests (like cholesterol and blood markers), diabetes monitoring (including glucose and A1c), and endocrine assessments (such as thyroid function tests). The Oklahoma Department of Health would administer the program, including public education campaigns targeting rural and underserved communities. The bill also mandates an annual legislative report tracking participation, health outcomes, and cost savings from preventative care.
