Endocrine, nutritional and metabolic diseases (E00-E89), in the block Diabetes mellitus (E08-E13).

What cannot be coded together with E09.3?

E09.3 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above E09.3 (E09) and apply to it just the same.

Excludes1 inherited from the categories above E09.3

These are not written on E09.3, but they bind it: a note on a category applies to every code beneath it. Billing E09.3 with anything listed here is a denial.

Written on E09 — Drug or chemical induced diabetes mellitus

diabetes mellitus due to underlying condition (E08.-)
gestational diabetes (O24.4-)
neonatal diabetes mellitus (P70.2)
postpancreatectomy diabetes mellitus (E13.-)
postprocedural diabetes mellitus (E13.-)
secondary diabetes mellitus NEC (E13.-)
type 1 diabetes mellitus (E10.-)
type 2 diabetes mellitus (E11.-)

Other codes that can never be billed with E09.3

These codes carry an Excludes1 note pointing at E09.3. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E09.3 alone.

E10Type 1 diabetes mellitus
E11Type 2 diabetes mellitus
E13Other specified diabetes mellitus
H28Cataract in diseases classified elsewhere
H36Retinal disorders in diseases classified elsewhere
E08Diabetes mellitus due to underlying condition

Risk adjustment

E09.3 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code history

E09.3 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
