ASC Coding: Part 4—Site-of-Service Differential

This article is from October 2005 and may contain outdated material.

Certain office-based services are subject to a facility-based reduction when performed in an ambulatory surgery center. This reduction applies only to services on the CMS list of ASC-covered services. From the “Eye and Ocular Adnexa” section of CPT, services that are subject to that site-of-service differential include the following:

65220  corneal, without slit lamp

65222  corneal, with slit lamp

65270  Repair of laceration; conjunctiva, with or without nonperforating laceration sclera, direct closure

65272  conjunctiva, by mobilization and rearrangement, without hospitalization
