OH HB691

Amends prompt payment requirements in sections 3901.38 and 3901.381-3901.3814 of the Revised Code to include Medicaid managed care organizations (MCOs) and Medicaid recipients as beneficiaries.

Modifies claim payment timelines: third-party payers must pay, deny, or request supporting documentation within 30 days; if documentation is requested, payers have 10 days to request it and 45 days total to pay or deny after receiving supporting documentation.

Prohibits third-party payers from denying claims solely due to lack of supporting documentation and establishes restrictions on when medical records or itemized reports can be requested prior to payment.

Requires third-party payers to publicly post a list of the 20 most frequently claimed health care services and specify what supporting documentation is routinely necessary to process those claims.

Establishes penalties for violations: 100% of aggregated delinquent claims for 20%+ monthly violations, and 50% of claims for every 14 days delinquent for individual unresolved claims; fines range from $100,000-$300,000 depending on offense history.
