Written on E10 Type 1 diabetes mellitus

  • diabetes mellitus due to underlying condition (E08.-)
  • drug or chemical induced diabetes mellitus (E09.-)
  • gestational diabetes (O24.4-)

Other codes that can never be billed with E10.3213

These codes carry an Excludes1 note pointing at E10.3213. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E10.3213 alone.

  • E11Type 2 diabetes mellitus
  • E13Other specified diabetes mellitus
  • Q45.3Other congenital malformations of pancreas and pancreatic duct
  • E09Drug or chemical induced diabetes mellitus
  • E08Diabetes mellitus due to underlying condition

Risk adjustment

E10.3213 risk-adjusts. Under the CMS-HCC V28 model it maps to these categories:

  • HCC 37 Diabetes with Chronic Complications0.166 RAF
  • HCC 37 Diabetes with Chronic Complications0.166 RAF
  • HCC 298 Severe Diabetic Eye Disease, Retinal Vein Occlusion, and Vitreous Hemorrhage0.336 RAF

Coefficient shown for the Community Non-dual Aged segment. A higher HCC in the same hierarchy will suppress this one, so capturing it does not always add score.
