as.decimal_diag: Get or set whether ICD codes have have an attribute...

In jackwasey/icd: Comorbidity Calculations and Tools for ICD-9 and ICD-10 Codes

Get or set whether ICD codes have have an attribute indicating 'short' or 'decimal' format

Description

Get or set whether ICD codes have have an attribute indicating 'short' or 'decimal' format

Usage

as.decimal_diag(x, value = TRUE)

as.icd_decimal_diag(x, value = TRUE)

as.short_diag(x, value = TRUE)

as.icd_short_diag(x, value = TRUE)

is.decimal_diag(x)

is.icd_decimal_diag(x)

is.short_diag(x)

is.icd_short_diag(x)

Arguments

x	ICD data
value	TRUE or FALSE, default is TRUE which sets the attribute to whatever is indicated in the function name. See examples.

Getting the attribute

is.short_diag tests for presence of an attribute, not whether the code is a valid ICD code. To test validity of the codes themselves, see is_valid.

Setting the attribute

Similarly, as.icd_short_diag and as.icd_decimal_diag set the attribute, but do not convert the codes themselves. For conversion between 'short' and 'decimal' forms, use decimal_to_short and short_to_decimal.

The attribute icd_short_code should be either TRUE or FALSE. There is no attribute named icd_decimal_code. These functions set and get the attribute safely. If the attribute is not present, both is.icd_short_diag and is.icd_decimal_diag (or their synonyms is.short_diag and is.decimal_diag) will return FALSE.

Examples

library(icd)
as.icd_short_diag("6670")
as.icd_short_diag("667.0") # no warning or error!
is.icd_short_diag(decimal_to_short("667.0"))
decimal_type_code <- as.icd_short_diag("667.0", FALSE)
stopifnot(is.icd_decimal_diag(decimal_type_code))
codes <- as.icd9(c("100.1", "441.3"))
codes <- as.decimal_diag(codes)
codes
