Retrieve ICD codes for Type 2 diabetes mellitus

Returns code sets from spec_diabetes_type2_v1. The definition is diagnosis-based (ICD-9 Type 2/unspecified codes 250.x0/250.x2 plus complication codes 357.2, 362.0x, 366.41; and ICD-10 E11.xx, E08.xx, E09.xx, E13.xx), with an alternative qualifying path of \(\geq\)1 pharmacy claim for an oral antidiabetic drug or insulin (see spec_diabetes_type2). Patients are further classified into four mutually exclusive categories (no diabetes; diabetes without antidiabetic medication; diabetes with oral antidiabetic; diabetes with insulin).

Usage

get_diabetes_type2_v1_codes(
  code_type = NULL,
  variable_type = c("condition", "outcome"),
  periods = FALSE,
  priority = 1L
)

get_diabetes_type2_v1_defs(variable_type = c("condition", "outcome"))

Arguments

code_type: Optional character vector of code types to return. Valid values: "dx_icd9", "dx_icd10", "proc_icd9", "proc_icd10", "hcpcs", "cpt", "rev". NULL (default) returns all code types.
variable_type: "condition" (default) or "outcome". Hypertension is defined as a condition only; "outcome" falls back to condition codes.
periods: Logical. FALSE (default) returns short-format codes (e.g., "4010"). TRUE returns decimal-format codes (e.g., "401.0").
priority: Integer vector subsetting confidence tiers to include (1 = core, 2 = probable, 3 = cautious). Default 1.
