HB 2619 prohibits Tennessee health insurance companies from using "downcoding" to reduce payments to healthcare providers. Downcoding occurs when insurers adjust a claim to a lower-cost procedure code, preventing providers from collecting full fees for services rendered - either from the insurer or the patient. The bill creates the Tennessee Commission of Insurance Review to handle complaints and enforce this rule. It directly affects healthcare providers (like doctors and hospitals) and health insurance entities operating in Tennessee by requiring full payment for covered services as defined in the bill. The law amends Tennessee insurance codes to clarify these requirements and definitions.
