icd9cm_hierarchy: ICD-9-CM diagnosis codes including leaf nodes and branch...

In icd: Comorbidity Calculations and Tools for ICD-9 and ICD-10 Codes

Description

Unlike get_icd9cm2014_leaf and friends, these data frames contain the full structure of the ICD-9-CM scheme up to the three-digit codes. Unlike the equivalent ICD-10-CM data frames (e.g., icd10cm2019), they do not have columns indicating billable/leaf status, or chapter designations.

Details

icd9cm_hierarchy is the deprecated name, which currently points to the final ICD-9-CM 2014 release. 2011 – 2014 are in fact identical. These are generated dynamically by parsing an awkward RTF file, and only the 2011 – 2014 data has been tested and used thoroughly.

Format: data frame
