2018 NASS Refinements

2018 NASS Refinements

The 2018 NASS applied updated versions of the HCUP Surgery Flag Software for Services and Procedures and the CCS for Services and Procedures Tool. As a result of the HCUP tool updates, the Current Procedural Terminology (CPT) procedures and CCS procedure groups defined as in-scope for the NASS sample changed slightly. Also, additional analyses revealed an inadequate capture of some procedures, because of an inability to obtain Level II HCPCS codes from all hospital-owned facilities in the sample. Percutaneous Transluminal Coronary Angioplasty (PTCA) CCS 45 was removed from the list of in-scope procedures in 2018.

A complete list of in-scope CCS procedure groups for each data year is included in Appendix B of the Introduction to the NASS on the NASS Database Documentation page on HCUP-US.
