Summary
Connecticut hospitals must now bill inpatient stays following observation/outpatient services with specific date requirements: admission date is the inpatient order date, service dates span the entire hospital stay, and covered days count from admission through discharge (excluding discharge date). Outpatient services must be rolled into the inpatient claim and cannot be billed separately.
Action Required
Immediately: Hospital billing teams must update billing procedures for inpatient admissions following observation/outpatient services. Set admission date as the inpatient order date (not arrival date), ensure service date range spans entire hospital stay from arrival to discharge, calculate covered days from admission date through discharge date excluding discharge day, and roll outpatient services into inpatient claims rather than billing separately. Update billing system rules to prevent separate billing of related outpatient services within the inpatient stay.
