Future versions of icd will drop
the icd_
prefix. For example, charlson
should be used in
favor of icd_charlson
. To distinguish icd function calls,
consider using the prefix icd::
instead, e.g., icd::charlson
.
Functions which specifically operate on either ICD-9 or ICD-10 codes or
their sub-types will retain the prefix. E.g.
icd9_comorbid_ahrq
. icd specific classes also retain
the prefix, e.g., icd_wide_data
.
