HB 4453 creates the Oklahoma Health Care Cost Transparency Board to oversee a statewide health care data database (APCD) and measure spending trends. It requires commercial health insurers to report primary care spending data annually and meet a minimum 11% spending target on primary care by 2030, using a standardized methodology from the Oklahoma Health Care Authority. The bill mandates the Insurance Department to collect and analyze cost data from insurers, Medicaid, and Medicare, then publish annual transparency reports. Insurers failing to meet benchmarks face potential penalties up to $5,000 per day for noncompliance. This directly affects commercial health insurers operating in Oklahoma.
