Summary
Arkansas Department of Human Services has expanded coverage for Revenue Code 158 (REHAB/WARD) to include inpatient hospital services in acute care settings. Starting September 1, 2026, inpatient hospitals will be reimbursed for Revenue Code 158 at rehabilitative per diem rates when only rehabilitative services are provided, subject to an upper limit with no cost settlement.
Action Required
By August 31, 2026: Billing team must update billing system to recognize and process Revenue Code 158 for inpatient hospitals (provider type 05) under the new reimbursement methodology. Verify that the system applies rehabilitative per diem rates for Revenue Code 158 claims and applies the upper limit without cost settlement. Update internal coding guidelines and train billing staff on the new revenue code reimbursement rules. Ensure all claims for dates of service on or after September 1, 2026 are submitted using the correct per diem rates to avoid claim denials or underpayment.
