Summary
CareSource is implementing enhanced documentation requirements for all laboratory services under Ohio Medicaid and Ohio MyCare plans, effective October 1, 2026. Ordering providers must maintain and submit medical necessity documentation within 45 days of MCO requests, or face claim denials and potential recoupment. This applies to both pre-adjudication and post-payment claim reviews.
Action Required
By September 30, 2026: (1) Billing team must audit current laboratory order documentation practices and ensure all ordering physicians maintain complete medical records documenting medical necessity per Ohio Administrative Code rule 5160-11-11. (2) Update billing workflows to flag laboratory services requiring prior authorization, especially those exceeding frequency limits. (3) Establish a process to track and respond to MCO documentation requests within the 45-calendar-day deadline. (4) Coordinate with laboratory providers to ensure they maintain copies of written orders, clinical diagnostic results, and narrative reports. (5) Update claim denial tracking procedures to distinguish between claims denied under this documentation review process (which do not trigger prompt pay rules) versus other denials. (6) Train billing and clinical staff on the new MCO request procedures and response deadlines. Failure to provide documentation will result in claim suspensions, denials, and recoupment actions with potential extrapolation sampling applied by the MCO.
