Colorado Claims Dispute & Statutory Guide
Colorado maintains a comprehensive state surprise medical billing framework under HB 19-1174 / C.R.S. § 10-16-704. Healthcare providers and insurers operate under a bifurcated dispute model: fully insured state-regulated plans fall under the State Arbitration & Payment Benchmark administered by Colorado Division of Insurance (DORA), while self-funded ERISA plans fall under the Federal No Surprises Act IDR portal.
