E09.311 — Drug or chemical induced diabetes mellitus with unspecified diabetic retinopathy with macular edema

BillableUnspecified

Is E09.311 billable?

Yes, but E09.311 is an unspecified code. E09.311 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, E09.311 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting E09.311 — the more specific alternatives are listed below.

Excludes1 — never code together — inherited from Chapter 4

The conditions below can never be reported together with E09.311 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • transitory endocrine and metabolic disorders specific to newborn (P70-P74)

Excludes1 — never code together — inherited from E09

The conditions below can never be reported together with E09.311 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • 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.-)

Code first — inherited from E09

The underlying condition below must be sequenced before E09.311. E09.311 describes a manifestation and cannot be the principal or first-listed diagnosis.

  • poisoning due to drug or toxin, if applicable (T36-T65 with fifth or sixth character 1-4)

Use additional code — inherited from E09

Report an additional code alongside E09.311 to fully describe the condition. E09.311 is sequenced first.

  • code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)
  • code to identify control using:
  • injectable non-insulin antidiabetic drugs (Z79.85)
  • insulin (Z79.4)
  • oral antidiabetic drugs (Z79.84)
  • oral hypoglycemic drugs (Z79.84)

How long has E09.311 existed?

E09.311 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.

Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
