Coding Clinic instructs to use only E13.10:
What is the correct code assignment for type 2 diabetes mellitus with diabetic ketoacidosis?
Assign code E13.10, Other specified diabetes mellitus with ketoacidosis without coma, for a patient with type 2 diabetes with ketoacidosis. Given the less than perfect limited choices, it was felt that it would be clinically important to identify the fact that the patient has ketoacidosis. The National Center for Health Statistics (NCHS), who has oversight for volumes I and II of ICD-10-CM, has agreed to consider a future ICD-10-CM Coordination and Maintenance Committee meeting proposal.
E13.10 please note: Type I exclude "type 2 diabetes mellitus E11.-)". Other specified diabetes refers to genetic beta-cell defects, genetic insulin defects, postpancreatectomy, etc. DM II is NOT an "other" DM. There is no instruction anywhere in the ICD-10 that I have found that instructs us to use an E13 code when the E13 code specifically notes DM II as a Type I exclude. Could someone please explain why we are not using E11.69 & e87.2 as we did last year? I'm having a difficult time explaining this to physicians. Thanks!
I would like to know as well? Seems strange to code E13.10 just because they have Ketoacidosis and then on other visits code them as type II? Does anyone know how to code LADA or DM type 1.5?
