chapters_to_map: Convert chapters to lists of codes for use as a comorbidity...
In icd: Comorbidity Calculations and Tools for ICD-9 and ICD-10 Codes
Description
The chapter headings can be converted into the full set of their children,
and then used to look-up which chapter, sub-chapter, or 'major' a given code
belongs. Always returns a map with short-form ICD-9 codes. These can be
converted in bulk with lapply and short_to_decimal.
Usage
1
chapters_to_map(x, defined = TRUE)
Arguments
x
Either a chapter list itself, or the name of one, e.g.
icd9_sub_chapters
defined
Single logical value, if TRUE, the default, only
officially defined ICD-9 (currently ICD-9-CM) codes will be used in the
expansion, not any syntactically possible ICD-9 code.
