Medical Mutual updated their Provider Manual with new ambulance claim validation edits effective June 2021, requiring CR1 and CRC segments. The newsletter also provides coding guidance for acute conditions in outpatient settings and transitions of care documentation requirements.

Action Required

Action needed
By June 2021: Billing team must ensure all ambulance claims include required CR1 (transport information) and CRC (certification) segments in 837 claim files to prevent processing delays. Update billing system validation for place of service codes 41 and 42. Review coding practices to avoid using acute diagnosis codes (like I63.XX) for follow-up visits in outpatient settings.
