ASC facility billing: covered lists, device costs, and discounting
An ambulatory surgery center is paid under its own system, and the first question on every claim is whether the procedure appears on the payer covered procedures list at all. A procedure that is perfectly appropriate clinically but sits outside the ASC list will be denied as a facility service no matter how clean the coding is. We screen the schedule against the covered list and the payer contract before the case, so surprises surface in pre-authorization rather than in the remittance.
Once the case is on the list, payment turns on multiple-procedure discounting, device-intensive rules, and implant documentation. Second and subsequent procedures in the same session are reduced, device-intensive procedures carry a device portion that must be substantiated, and a case stopped before or after anesthesia induction uses distinct discontinued-procedure modifiers that determine whether the center is paid partially or not at all. Facility and professional claims also have to agree, because mismatched operative detail between the two invites review of both.
Coding and documentation focus
- ✓Covered procedures list screening — Every scheduled case is checked against the payer ASC list and contract terms before the date of service.
- ✓Multiple procedure discounting — Additional procedures in the same session are paid at a reduced rate, so ranking the primary procedure correctly protects the highest allowable.
- ✓Device-intensive and implant support — Device portions and high-cost implants need invoice-level backup ready before the claim, not after the denial.
- ✓Discontinued procedure modifiers — Cases halted before versus after anesthesia induction use different modifiers, and the choice decides whether the facility is paid.
Denials we prevent on these claims
- ✓Procedure not on the payer ASC covered list — screened at scheduling instead of after the case.
- ✓Implant or device cost denied for lack of invoice — documentation packaged with the claim up front.
- ✓Discounting applied to the wrong primary procedure — we sequence by allowable to protect payment.
- ✓Facility and surgeon claims describing different operative detail — reconciled before both are released.
Frequently asked questions
Why was our ASC claim denied when the surgeon was paid?
Facility and professional claims are adjudicated separately under different rules. The most frequent cause is that the procedure is not on the payer approved ASC list, so the surgeon fee is payable while the facility component is not. Confirming the covered list before scheduling is the fix.
How is a cancelled case billed?
It depends on when the case stopped. A procedure discontinued before anesthesia induction and one discontinued after induction use different modifiers and produce very different payment, so the operative record has to state clearly at what point the case was halted.
