Summary
CareSource (Ohio Medicaid, Marketplace, and MyCare Ohio) has established new submission requirements for itemized bills effective immediately. All itemized bills must be submitted in text-only format with specific structural requirements including MM/DD/YYYY date format, required header fields (Date, Revenue Code, CPT Code, Description, Quantity, Charges), and reconcilable charges at claim and revenue code levels. Noncompliance may result in processing delays, requests for corrected documentation, or claim denial.
Action Required
Immediately: Billing team must audit and update all itemized bill submission processes for Ohio Medicaid, Ohio Marketplace, and CareSource MyCare Ohio claims to comply with new requirements. (1) Convert all itemized bill templates to text-only format (eliminate images, scans, handwritten documents). (2) Implement MM/DD/YYYY date formatting system-wide. (3) Ensure all itemized bills include member name, claim ID, date-of-service range (from/to dates), and total charges. (4) Restructure itemized bill output to display columns in exact order: Date, Revenue Code, CPT Code, Description, Quantity, Charges. (5) Implement validation logic to verify charges reconcile at claim level AND within each revenue code grouping before submission. (6) Train all billing staff on new format requirements. Communicate deadline: this policy is effective immediately (September 3, 2026). Failure to comply will result in processing delays, requests for corrected documentation, and potential claim denials.
