Get Charlson Codes

Retrieve a copy of internal lookup tables for the ICD codes used in assessing Charlson comorbidities.

Usage

get_charlson_codes()

Value

A data.frame with the following columns:

• icdv: Integer vector indicating if the code is from ICD-9 or ICD-10

• dx: Integer vector. 1 if the code is a diagnostic, (ICD-9-CM, ICD-10-CM, WHO, CDC Mortality), or 0 if the code is procedural (ICD-9-PCS, ICD-10-PCS)

• full_code: Character vector with the ICD code and any relevant decimal point

• code: Character vector with the compact ICD code

• condition: Character vector of the conditions

• charson_\<variant\>: Integer vector indicating if the code is part of the \<variant\> of the Charlson comorbidities.
