Summary
MO HealthNet Division issued critical clarification on ABA service billing documentation requiring providers to document exact start/stop times, subtract all non-billable time (naps, meals, breaks), and submit only one line per procedure code per day with total daily units calculated from net active minutes. Block billing without detailed time breakdowns will trigger post-payment recoupment. This represents a strict enforcement of documentation and billing practices effective immediately.
Action Required
Immediately: (1) Billing team must update all claim submission processes to require providers to document exact start/stop times for each ABA service in participant records—eliminate block billing format. (2) Implement software rules to reject or flag any claims with multiple lines for the same procedure code on the same day; claims will be denied as duplicates in eMOMED. (3) Billing team must recalculate and consolidate all daily ABA units by procedure code using the 15-minute unit conversion table provided, summing net active minutes for the entire day before converting to units. (4) Provide immediate training to all billing staff and clinical providers on non-billable time categories (naps, meals, routine breaks, free play, administrative time, status-only conversations, post-session note writing). (5) Create and implement audit checklist for submitted claims to verify: exact start/stop times documented, non-billable time subtracted, one line per procedure code per day, and proper 15-minute unit conversion. (6) Communicate to all ABA providers that failure to document and bill per this guidance will result in post-payment claim recoupment by MO HealthNet Division. (7) Review recent claims (last 30-60 days) for compliance and prepare for potential recoupment notices.
