E11.A

E11.A — Type 2 diabetes mellitus without complications in remission

Billable / specific codeICD-10-CM

E11.A is a billable, specific ICD-10-CM code for type 2 diabetes mellitus without complications in remission. It is valid for submission on a claim.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

type 2 diabetes mellitus, with complications (E11.0-E11.8)
type 2 diabetes mellitus, without complications not in remission (E11.9)

Other codes that can never be billed with E11.A

These codes carry an Excludes1 note pointing at E11.A. 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.A alone.

E11.9Type 2 diabetes mellitus without complications

Risk adjustment

E11.A 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.

Medicare coverage

E11.A is named in 3 Medicare coverage policies — 3 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
