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.
