NOTE: Significant changes in 2014 for reporting outpatient procedures.
As of July 1, 2014, changes were made in the requirements for Vermont hospitals’ reporting of all outpatient procedures and services. Prior to that date, outpatient procedures were reported using the ICD-9-CM coding system; these codes were included as appropriate on each individual discharge record with a primary procedure code determined by the reporting hospital. As of July 1, 2014, outpatient procedures are reported using the HCPCS/CPT coding system; these codes are included on each of one-to-many revenue records, and there is no determination by the reporting hospital of which CPT code is considered to be primary. Therefore, a primary CPT code has been calculated and flagged for each outpatient discharge using an algorithm that includes relative value units, charges, and whether the CPT code is for an ambulatory surgical procedure. Any CPT codes reported prior to July 1, 2014 are considered incomplete, as are any ICD-9-CM procedure codes reported on or after that date.
To ensure that analyses of outpatient procedures include complete data that are as consistent across time as possible, the 2014 files include two new fields (CCSPROC and CCSPROCGRP) that have been created using Clinical Classifications Software (CCS). This software groups both ICD-9-CM procedure codes and HCPCS/CPT codes into the same single and high level categories based on body systems. For the first half of 2014, groupings are based on the first procedure in ICD-9-CM range 00.00-86.99, and for the second half of 2014 groupings are based on the primary CPT. In analyses that include prior years of data, these new fields are comparable to the earlier CCSPPX and CCSPPXGRP fields. Some discontinuities may exist due to differences between the two coding systems.
No changes were made to the reporting of inpatient procedures, and ICD-9-CM codes were used throughout 2014. CCSPPX and CCSPPXGRP have been renamed to CCSPROC and CCSPROCGRP in the inpatient data file for consistency across hospital settings in 2014 and forward.
NOTE: Significant changes in 2015 for reporting all diagnosis codes, and inpatient procedure codes.
As of October 1, 2015, federal regulations require that all diagnosis codes be reported using the ICD-10-CM coding system, and that all inpatient procedure and service codes be reported using the ICD-10-PCS system.
