What cannot be coded together with E11.4?

E11.4 — Type 2 diabetes mellitus with neurological complications

Non-billable headerICD-10-CM

Excludes1 inherited from the categories above E11.4

These are not written on E11.4, but they bind it: a note on a category applies to every code beneath it. Billing E11.4 with anything listed here is a denial.

Written on E11 — Type 2 diabetes mellitus

diabetes mellitus due to underlying condition (E08.-)
drug or chemical induced diabetes mellitus (E09.-)
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.-)

Other codes that can never be billed with E11.4

These codes carry an Excludes1 note pointing at E11.4. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E11.4 alone.

E10Type 1 diabetes mellitus
E09Drug or chemical induced diabetes mellitus
E08Diabetes mellitus due to underlying condition

Risk adjustment

E11.4 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.
