What the data shows for Oklahoma

Oklahoma's marketplace insurers denied 23.8% of submitted claims in the CMS data, the 5th-highest rate of the 31 states with federal marketplace filings. Denial rates this far above the 21% national average usually reflect the state's mix of plan types and risk pool rather than any single carrier — Medicaid managed-care and narrow-network plans route more claims through utilization review.

On the auto side, drivers in Oklahoma pay an average $1085 a year — less than the $1191 national average — split across $566 liability, $421 collision and $338 comprehensive premiums. That figure has moved up 19% since 2019, tracking the national surge in repair and medical-claim costs.

Because rate regulation, licensing and guaranty-fund coverage are set state by state, an insurer's record in Oklahoma can differ from its national average — which is why the state view matters for local consumers.
