Usage

icd9ExpandMinor(minor = "", isE, invalidAction = icd9InvalidActions)
icd9ExpandMinorNV(minor = "")
icd9ExpandMinorE(minor = "")

Arguments

minor

character vector of 'minor' part of ICD-9 codes, i.e. that part which falls after the decimal point, in decimal notation. (In 5 digit notation, the 'major' part is be xyz, even when x and y are zero, thus the last two characters represent the 'minor' part

isE

single logical, which if TRUE, treats the minor as part of an E code (which is one character), as opposed to a V or numeric-only code, which is two character. No default.

Value

• NA for invalid minor, otherwise a vector of all possible (perhaps non-existent) sub-divisions.
