icd9_majors

<p><code>icd9_chapters</code>, <code>icd9_chapters_sub</code> and <code>icd9_majors</code> contain
mappings from the higher level descriptions of ICD-9 codes to the ranges of
ICD-9 codes they describe. Helpful in summarizing codes or grouping for
human-readable output. These can easily be converted to a co-morbidity
mapping, as shown in the vignette.</p>

Calculate comorbidities, medical risk scores, and
work very quickly and precisely with ICD-9 and ICD-10 codes. This
package enables a work flow from raw tables of ICD codes in hospital
databases to comorbidities. ICD-9 and ICD-10 comorbidity mappings from
Quan (Deyo and Elixhauser versions), Elixhauser and AHRQ included.
Common ambiguities and code formats are handled. Comorbidity
computation includes Hierarchical Condition Codes, and an
implementation of AHRQ Clinical Classifications. Risk
scores include those of Charlson and van Walraven.  US Clinical
Modification, Word Health Organization, Belgian and French ICD-10
codes are supported, most of which are downloaded on demand.
