pr.get.icd.ver: Checks if it is ICD-9 or ICD-10

In gforge/comorbidities.icd10: Calculates Comorbidity Indices Based on ICD-9/10

Description

Identifies if first letter is a number or V and then suggests ICD-9. There are V-codes in ICD-10 although these are only transportation related disease causes such as biking and automobile accidents. It is therefore better to sort any of these codes into the ICD-9 in case they actually belong there.

Usage

pr.get.icd.ver(codes, icd_ver = rep(FALSE, times = length(codes)))

Arguments

codes	A vector with ICD-codes
icd_ver	A vector with icd versions, has to have the length of 1 or the same length as code argument. If FALSE then all are checked otherwise only those that are FALSE are checked.

Value

vector Returns a vector of the same length as the codes whith a number corresponding to to the ICD-version.

Important note

The E-code for the "SUPPLEMENTARY CLASSIFICATION OF EXTERNAL CAUSES OF INJURY AND POISONING (E800-E999)" are not included in the icd-9 as they are part of the metabolic spectra for ICD-10. Likewise the V-codes are defaulted to ICD-9.
