icd9 (version 1.0)

icd9GetValid: invalid subset of decimal or short ICD-9 codes

Description

Given vector of short or decimal ICD-9 codes, return (in the same format) those codes which are valid or invalid. Useful for generating error messages with the faulty codes if validation fails.

Usage

icd9GetValid(icd9, isShort = icd9GuessIsShort(icd9))

icd9GetValidDecimal(icd9Decimal)

icd9GetValidShort(icd9Short)

icd9GetInvalid(icd9, isShort = icd9GuessIsShort(icd9))

icd9GetInvalidDecimal(icd9Decimal)

icd9GetInvalidShort(icd9Short)

Arguments

icd9

is a character vector of ICD-9 codes. If fewer than five characters is given in a code, then the digits are greedily assigned to hundreds, then tens, then units, before the decimal parts. E.g. "10" becomes "010", not "0010"

isShort

single logical value which determines whether the ICD-9 code provided is in short (TRUE) or decimal (FALSE) form. Where reasonable, this is guessed from the input data.

icd9Decimal

character vector of ICD-9 codes. If fewer than five characters is given in a code, then the digits are greedily assigned to hundreds, then tens, then units, before the decimal parts. E.g. "10" becomes "010", not "0010"

icd9Short

is a character vector of ICD-9 codes. If fewer than five characters is given in a code, then the digits are greedily assigned to hundreds, then tens, then units, before the decimal parts. E.g. "10" becomes "010", not "0010"
