Why ASC Billing Matters for Your Practice
ASC billing is facility billing — completely different from physician billing. Facility fees, device-intensive procedure billing, OPPS-adjacent payment systems, and the constant challenge of implant documentation make ASC revenue cycle management a specialized discipline.
Our ASC billing team works exclusively with ambulatory surgical centers. We know the APC grouper, the device-offset edits, and every payer's ASC-specific fee schedule — because the difference between correct and incorrect ASC billing can be $5,000+ per case.

Sound Familiar? These Mistakes Are Costing You Revenue
Most practices silently lose 15–30% of collectible revenue to these avoidable problems.
Implant Documentation Not Attached
High-cost implant claims are denied without proper invoice documentation. Missing a single implant attachment can mean $10,000+ lost per joint replacement case.
Wrong Procedure Code for ASC Setting
Some CPT codes reimburse differently in ASC vs. HOPD vs. physician office settings. Selecting wrong codes for the ASC setting means systematic underpayment.
Device-Intensive Procedure Under-Billing
Device-offset rules and pass-through device billing are complex and frequently misapplied. Our team knows every device category that qualifies for separate billing.
Carve-Out Services Missed
Certain services "carved out" from the facility fee (implantable devices, certain drugs) can be billed separately. Missing these carve-outs is systematic revenue loss.
Practices trust ZenoMedix RCM to fix these exact problems.
CPT & HCPCS Codes Involved in ASC Billing
A sample of the procedure and service codes our team routinely works with as part of asc billing.
Denial Codes Our ASC Billing Team Resolves
Standard CMS/payer Claim Adjustment Reason Codes (CARCs) and Remittance Advice Remark Codes (RARCs) we see most often, and how we resolve them.
❌ CO-96 / M15 — Non-Covered Charge — Implant Not Separately Payable
A device or implant billed without the invoice documentation the payer requires for cost pass-through gets denied as included in the facility payment.
✓ Our Fix
We attach the implant invoice to every qualifying claim at submission per each payer's specific pass-through documentation rule, rather than after a denial forces a resubmission.
❌ CO-151 — Payer Deems Information Doesn't Support Frequency/Setting
Some CPT codes reimburse differently — or not at all — in the ASC setting versus HOPD or physician office, and billing the wrong site-of-service designation triggers this denial.
✓ Our Fix
We verify ASC-setting payability for every procedure code before submission using each payer's ASC-specific covered procedures list.

ASC Billing FAQ
Yes. We can manage professional billing (surgeon and anesthesia) and facility billing simultaneously, ensuring correct split billing with no component missed or duplicated. Having one team manage both reduces coordination errors.
We collect implant invoices from your OR staff for every qualifying case, attach them to the UB-04 claim, and bill per each payer's implant cost passthrough requirements. We track which payers require invoice documentation vs. which have flat implant rates.
Medicare uses a "device-offset" system where the device cost is subtracted from the procedure APC payment, then the device is paid separately. Incorrectly applying device-offset edits results in either double-payment or missed device reimbursement. Our team applies these rules precisely.
Yes. ASC Medicare certification and payer credentialing is handled by our credentialing team. We manage the CMS 855B application, state survey preparation, and commercial payer ASC-specific enrollment.
Most ASCs underperform on facility billing because their staff handles both scheduling and billing — with billing being secondary. Our dedicated ASC billing team focuses exclusively on claims, and our collection rates for ASC clients average 12–18% higher than industry benchmarks.
