About this code
Type 2 diabetes mellitus with ketoacidosis without coma.
E11.10 is an ICD-10-CM diagnosis code for type 2 diabetes mellitus with ketoacidosis without coma. It sits in the 4. Endocrine, nutritional, metabolic chapter of the U.S. clinical modification, under category E11.
This code is billable on U.S. healthcare claims when supported by appropriate clinical documentation. The patient chart must establish the diagnosis, capture any clinical detail encoded in the code (severity, laterality, encounter type, complications where applicable), and demonstrate medical necessity for the billed services.
Payer-specific coverage rules vary. Always cross-check against the current Local Coverage Determinations (LCDs) and National Coverage Determinations (NCDs) for the payer adjudicating the claim, plus any specialty-specific CMS Medicare Administrative Contractor guidance.
Billing context
What practitioners watch for on E11.10.
Chapter-level billing guidance for endocrine, nutritional, metabolic codes. Code-specific notes ship as the dataset matures.
Documentation
Document the disorder specifically (type 1 vs type 2 diabetes, controlled vs uncontrolled), associated complications (neuropathy, nephropathy, retinopathy), and current treatment (insulin status). The "with" convention in ICD-10-CM links manifestations to the underlying condition.
Common denial categories
- CO-16: Information missing or incorrect on the claim or in supporting documentation. Add documentation specificity that supports the coded detail; resubmit with corrected information.
- CO-50: Service not deemed medically necessary by the payer. Confirm the diagnosis-procedure relationship matches LCD/NCD coverage, attach clinical justification, appeal with documentation.
- CO-11: Diagnosis is inconsistent with the procedure performed. Verify the diagnosis-to-procedure pairing per payer policy; correct the linked diagnosis pointer or the procedure code.
Coverage signal
Endocrine coverage is generally broad. Type 2 diabetes (E11) codes follow the "with" convention: a manifestation listed under the parent E11 code is presumed related unless documented otherwise.
