ICD-10 codes for diabetes

Diabetes coding in ICD-10-CM is built on combination codes: the fourth and fifth characters encode the complication. E11.9 (type 2 without complications) is correct only when the record genuinely documents no complications.

Notat skriver notatet — og foreslår disse koder

Den samme FactsContext™-motor, der extractor koder her, gør hele konsultationen til et struktureret klinisk notat, hvor hver kode er knyttet til den sætning, der understøtter den. Du gennemgår og underskriver hvert notat.

Type 2 diabetes ICD-10 codes

Start with the primary code, then move to a more specific related code when the documentation supports it.

E11.9

Type 2 diabetes mellitus without complications

ICD-10-CM

E11.65

Type 2 diabetes with hyperglycemia

ICD-10-CM

E11.22

Type 2 diabetes with diabetic chronic kidney disease

Code also the CKD stage (N18.-)

ICD-10-CM

E11.40

Type 2 diabetes with diabetic neuropathy, unspecified

ICD-10-CM

E11.319

Type 2 diabetes with unspecified diabetic retinopathy without macular edema

E10.9

Type 1 diabetes mellitus without complications

ICD-10-CM

Z79.4

Long-term (current) use of insulin

Add for type 2 patients on insulin

ICD-10-CM

Sådan vælger du den rigtige kode

Pick the combination code that matches the documented complication — do not code E11.9 plus a separate complication code. Documented hyperglycemia moves you to E11.65; kidney involvement to E11.2- plus the CKD stage; neuropathy to E11.4-; retinopathy to E11.3-. Add Z79.4 when a type 2 patient uses insulin long-term.

Dokumentationseksempel

Type 2 diabetes review. HbA1c 8.9%, up from 7.8%. Reports polyuria this month. No visual symptoms; last retinal screen normal. Monofilament exam normal. Started empagliflozin 10 mg; continue metformin.

E11.65

Ikke direkte transskriptionsgætning

FactsContext extracts clinical facts first: diagnoses, symptoms, negatives, findings, test results, medications, and plan decisions.

Rå fakta forbliver brugbare

The clinician can read and reuse the extracted medical context directly, independent of the generated note.

FAQ

What is the ICD-10 code for type 2 diabetes?

The ICD-10 code for type 2 diabetes is E11.9 (Type 2 diabetes mellitus without complications). Related codes include E11.65, E11.22, E11.40. Confirm the most specific code against the documented clinical detail before billing.

When is E11.9 wrong?

Whenever a complication is documented. Elevated glucose or HbA1c with symptoms documented as hyperglycemia should be coded E11.65, not E11.9 — the combination code carries the complication.

How do I code diabetes with CKD?

Use E11.22 (type 2 with diabetic CKD) together with the CKD stage code from N18.-. Both codes are required.

Can AI find the right diabetes combination code?

Notat extracts the documented complications as clinical facts and suggests the matching combination codes with their evidence, so you can verify against the note before accepting.
