Convert ICD Compact Codes to Full Codes

Take an assumed ICD compact code string and convert to a full code based on the ICD version (9 or 10) and type (diagnostic or procedure). This method only formats strings and does not validate the code(s).

Usage

icd_compact_to_full(x, icdv, dx)

Arguments

x

Character vector

icdv

Integer vector of allowed ICD versions. Use 9L and/or 10L. Defaults to both.

dx

Integer vector indicating allowed code type(s): 1L for diagnostic (ICD-9-CM, ICD-10-CM, CDC mortality, WHO), 0L for procedural (ICD-9-PCS, ICD-10-PCS). Defaults to both.

Value

A character vector the same length as x.
