Ambulatory Surgery Center (ASC) Billing
Specialized facility claims management, implant carve-out reconciliation, and rapid denial recovery for freestanding and hospital-affiliated surgery centers.
Overcoming the Cash-Flow Pitfalls of Facility Reimbursement
Ambulatory Surgery Centers operate under intense margin pressure. Between escalating supply and implant overhead, complex Medicare ASC Payment System (APC) payment formulas, and commercial payer carve-out rules, facility claims require distinct operational expertise that typical professional billers lack.
Ecardius provides revenue cycle workflows fully compatible with ASC facility billing, experienced in managing both CMS-1500 (Box 24/33 billing with modifier -SG) and UB-04 electronic 837I submissions across multispecialty and single-specialty surgical suites.
Critical ASC Revenue Leaks We Solve
1. Unreimbursed High-Cost Implants & Hardware
Spine, orthopedic, and ophthalmologic implants represent tens of thousands in cash outlays. Payers frequently deny or underpay implant carve-outs due to missing manufacturer itemized invoices, lack of pre-certification, or missing HCPCS C-codes and L-codes. We attach verified invoices and reconcile allowable markup rates on every claim.
2. Discontinued Procedure Modifier Handling (-73 / -74)
When a scheduled surgical case is cancelled due to patient condition (e.g., adverse anesthesia reaction, acute hypertension), centers often lose full facility reimbursement. We ensure accurate use of modifier -73 (discontinued prior to anesthesia, reimbursed at 50%) or -74 (discontinued after anesthesia, reimbursed at 100%) to secure rightful facility compensation.
3. Multiple Procedure Discounting Calculations
Under Medicare and commercial ASC rules, the primary surgical code is paid at 100% of the allowable rate, while secondary procedures within the same operative session are reduced to 50%. We audit charge sequencing to ensure the highest-reimbursing procedure is adjudicated as the primary code.
4. Medicare ASC Covered Procedures List (CPL) Verification
CMS annually modifies the list of procedures approved for payment in the ASC setting. Billing a CPT code excluded from the Medicare CPL results in complete non-coverage. We scrub surgical bookings against current CMS CPL rules prior to patient admission.
