Ambulatory Surgical Center (ASC) Payment System

This file contains a summary of service utilization by ASC supplier and is derived from 2010 ASC line item level data, updated through March 2011, that is, line items for services furnished on or after January 1, 2010 through December 31, 2010 that were received, processed, paid, and passed to the National Claims History file by March 31, 2011.  This file contains data for ASC services billed in 2010, including services that were added under the revised ASC payment system. We revised CY 2010 HCPCS codes (where appropriate) to reflect their CY 2011 and CY 2012 payment status and description using an internal CY 2010 and CY 2011 to CY 2012 crosswalk file.  This file includes 715,554 records summarized first at the supplier level and then at the HCPCS code level. This is a flat file that is available on DVD.

The ASC LDS file will be available twice a year, once for the NPRM in late spring/early summer, and again for the final rule within a month of publication of the OPPS final rule in the Federal Register.
