Ambulatory Surgical Center (ASC) Payment System

This file contains a summary of service utilization by ASC supplier and is derived from 2013 ASC line item level data, updated through March 2014, that is, line items for services furnished on or after January 1, 2013 through December 31, 2013 that were received, processed, paid, and passed to the National Claims History file by March 31, 2014.  This file contains data for ASC services billed in 2013, including services that were added under the revised ASC payment system.  We revised CY 2013 HCPCS codes (where appropriate) to reflect their CY 2014 payment status and description using an internal CY 2013 to CY 2014 crosswalk file.  This file includes 733,552 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.
