Include and Excludes1 Examples
IN ICD-10-CM, DIABETES mellitus tabular inclusion notes are introduced by the term “Includes” and appear at the beginning
of a category. The “Excludes1” note, meaning “Not coded here,” appears under all the diabetes mellitus categories. An Ex-
cludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note.
E13, Other specified diabetes mellitus
Includes: Diabetes mellitus due to genetic defects of be-
ta-cell function
Diabetes mellitus due to genetic defects in insu-
lin action
Postpancreatectomy diabetes mellitus
Postprocedural diabetes mellitus
Secondary diabetes mellitus NEC
E10, Type 1 diabetes mellitus
Excludes1: Diabetes mellitus due to underlying condition
(E08.-)
Drug or chemical induced diabetes mellitus
(E09.-)
Gestational diabetes (O24.4-)
Hyperglycemia NOS (R73.9)
Neonatal diabetes mellitus (P70.2)
Postpancreatectomy diabetes mellitus (E13.-)
Postprocedural diabetes mellitus (E13.-)
Secondary diabetes mellitus NEC (E13.-)
Type 2 diabetes mellitus (E11.-)
There is a combination code for the type 2 diabetes with
chronic kidney disease, and the tabular instructs the coder to
use an additional code to identify the stage of the chronic kidney disease. At the E11 category level, the Use additional code
note instructs the coder to identify insulin use.
In another case, a female patient with type 1 diabetes is seen
for severe nonproliferative diabetic retinopathy with macular
edema. The coding here would be:
No additional codes are necessary because there is a combi-
nation code for the type 2 diabetes with nonproliferative diabet-
ic retinopathy with macular edema.
