Summary
MO HealthNet clarified billing guidelines for multiple surgical procedures performed on the same patient and date of service. When procedures use the same incision, only the major procedure is paid at 100%. When using separate incisions, the major procedure pays 100%, secondary pays 50%, and tertiary pays 25%.
Action Required
Immediately: Billing team must review all multiple surgery claims to ensure proper billing according to MO HealthNet guidelines. For same incision procedures, bill only the major procedure. For separate incisions, bill major procedure at 100%, secondary at 50%, tertiary at 25%. Update billing system rules and consider attaching operative reports to multiple surgery claims to expedite processing.
