Prohibits downcoding in health insurance claims.

This bill prohibits health insurance companies and other payers in New Jersey from "downcoding" claims - meaning they cannot adjust claims to a lower-cost service code to pay providers less than what is owed for the actual service performed. It directly affects healthcare providers (like doctors and hospitals) who submit claims for services, ensuring they can collect full payment for the care they delivered. The law requires payers to reimburse providers based on the actual service documented, not a downcoded version, and mandates the Department of Banking and Insurance to create implementing regulations. Downcoding typically occurs when insurers dispute a service code, but this bill prevents them from using it to reduce payments unfairly.
