This does not check whether the code coresponds to a real
ICD-9-CM billing code, or parent grouping. For that, see
icd9IsReal
.
Factors are accepted, and since the validation is done with grepl
these are handled correctly.
Currently, there is a limitation on NA values. Calling with NA
(which is a logical vector of length one by default) fails, because it is
not a string. This is rarely of significance in real life, since the NA
will be part of a character vector of codes, and will therefore be cast
already to NA_character
NA
values result in a return value of FALSE
.

icd9 |
is a character vector or factor 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" |

major |
character vector of 'major' part of ICD-9 codes, i.e. that part which falls before the decimal point, in decimal notation. (In 5 digit notation, the 'major' part is be the first three characters (with leading zeroes), and includes V or E prefix. xyz |
Leading zeroes in the decimal form are not ambiguous. Although integer ICD-9 codes could be intended by the user, there is a difference between 100, 100.0, 100.00. Therefore a warning is given if a numeric value is provided
logical vector with TRUE
or FALSE

provided according to its validity
isValidMajor
validates just the
'major' three-digit part of an ICD-9 code. This can in fact be provided as
a numeric, since there is no ambiguity. Numeric-only codes should be one to
three digitis, V codes are followed by one or two digits, and E codes
always by three digits between 800 and 999.
