Overview

Billing in Ambulatory Surgery

A practical view of what makes this specialty unique.

Ambulatory Surgery Center (ASC) billing is unique, involving facility fees for surgical procedures performed in the outpatient setting, separate from professional fees. This requires a deep understanding of the ASC payment system, covered procedures lists, and specific billing rules for implants and devices. Our ASC billing service is designed to optimize your center's revenue, ensuring accurate coding for all surgeries, proper handling of implantable device charges, and compliance with CMS and commercial payer ASC regulations.
