Clinical Classifications Software Refined (CCSR): map to 4-character ICD codes

Source: R/reference.R

A map of 538 clinical concepts to 4-character ICD codes adapted from the Clinical Classifications Software Refined (CCSR) (Healthcare Cost and Utilization Project 2020) .

ccsr

Format

A data frame with 72,715 ICD-10-CM codes mapped to CCSR categories.

Source

Adapted from (Healthcare Cost and Utilization Project 2020) for 4-character ICD-10 codes.

Details

The Clinical Classifications Software Refined (CCSR) is a database developed as part of the Healthcare Cost and Utilization Project (HCUP) which maps ICD-10-CM codes into 538 CCSR categories. Unlike the pre-existing ccs:

  • CCSR categories are not mutually exclusive.

  • CCSR contain categories not found in ccs

  • CCSR categories are organised into 21 body systems
