Which codes are often used to report ambulatory surgical center services?

CPT codes are the correct choice for reporting ambulatory surgical center (ASC) services because they specifically describe medical, surgical, and diagnostic services and procedures provided by healthcare professionals. These codes provide detailed descriptions for a wide variety of procedures and services, which align closely with the activities performed in an ASC setting, such as outpatient surgeries and procedures.

While ICD codes are utilized for reporting diagnoses and conditions, they do not capture the specifics of the procedures being performed. HCPCS Level II codes are mostly employed for products, supplies, and certain services not covered by CPT codes, such as transportation and non-physician services. Modifiers, on the other hand, are used to provide additional information about the procedure performed, but they do not represent the services themselves.

Due to the nature of ASC services being procedural and often surgical in scope, CPT codes are the most appropriate and commonly utilized for accurate billing and documentation in these healthcare environments.
