ASC Billing That Maximizes Every Surgical Case

Ambulatory Surgery Centers operate under a completely different reimbursement framework than physician offices or hospitals. A2Z Billing’s ASC specialists understand facility-fee billing, CMS payment classifications, and payer-specific ASC rules, so your center captures every dollar it has earned.

Why ASC Billing Is Its Own Specialty

ASCs face a unique reimbursement landscape. Facility fees, CMS Ambulatory Payment Classifications, implant billing, and multi-payer coordination create complexity that most billing teams aren’t equipped to handle.

Facility Fee vs. Professional Fee Confusion

ASC billing requires precise separation of facility and professional components

CMS Ambulatory Payment Classifications

Correct APC assignment is critical for Medicare reimbursement. Even minor misclassifications directly reduce payment rates across every affected claim.

Implant & Surgical Device Billing

High-cost implants and devices require specific documentation and billing protocols. Without them, payers routinely deny or reduce reimbursement entirely.

Payer-Specific ASC Contracts

Each commercial payer has unique ASC fee schedules, prior authorization requirements, and documentation standards.

High Case Volume & Velocity

ASCs process high volumes with tight turnaround expectations. Any slowdown in claim submission directly impacts your center's cash flow and operational stability.

Bundling & Unbundling Rules

Complex bundling rules apply to surgical procedures across all payers. Incorrect bundling leaves revenue on the table; incorrect unbundling triggers audits and recoupments.

FAQs

How is ASC billing different from hospital outpatient billing?

ASCs are reimbursed at different rates than hospital outpatient departments under Medicare's Ambulatory Payment Classification system. ASCs bill using UB-04 facility claims under their own NPI and tax ID, separate from any physician professional fees. The payer rules, fee schedules, prior authorization requirements, and covered procedure lists are all distinct from hospital outpatient billing.

Can A2Z Billing handle both facility and professional fee billing?

We manage ASC facility fee billing (UB-04) and can also handle professional fee billing (CMS-1500) for surgeons and anesthesiologists operating within your center. We coordinate both billing streams to prevent conflicts, duplicate billing, and payer sequencing errors.

How do you handle prior authorizations for ASC procedures?

We obtain and verify prior authorizations for every scheduled case before the patient arrives, verifying that the correct procedure codes, diagnosis codes, and facility NPI are included on each authorization. We also track authorization expiration dates and proactively follow up on pending auths. This prevents last-minute denials and ensures your center is fully covered before every case goes to the OR.

Do you bill for implants and high-cost surgical devices?

We document and bill all pass-through devices and high-cost implants per each payer's specific requirements, including invoice documentation, correct revenue code assignment, and separate billing where applicable. For high-volume orthopedic and spine ASCs, proper implant billing alone can recover tens of thousands of dollars in previously lost annual revenue.

Which payers do you have ASC billing experience with?

We bill all major payers for ASC facilities, including Medicare, Medicaid, Blue Cross Blue Shield, UnitedHealthcare, Aetna, Cigna, Humana, commercial PPO and HMO plans, workers' compensation carriers, and self-pay patients. We have deep working knowledge of payer-specific ASC fee schedules and prior authorization portals, enabling faster submissions and fewer denials across your entire payer mix.
