E11.65: Type 2 diabetes mellitus with hyperglycemia
Billable ICD-10-CM code, FY2027
What E11.65 covers
E11.65 is for type 2 diabetes with hyperglycemia. The Alphabetic Index sends diabetes described as poorly controlled, inadequately controlled or out of control to the hyperglycemia code, so this is where those terms land for type 2.
Primary care and endocrinology use it often. It sits in E11.6, other specified complications, next to E11.64 for hypoglycemia and E11.69 for other specified complications. Type 2 diabetes with no complications is E11.9.
Billing and coding notes
The guidelines say to use as many codes from E11 as needed to describe all the complications. So E11.65 can be reported with other E11 complication codes, such as E11.22 for diabetic CKD. It is not reported with E11.9.
The E11 category asks for an additional code for treatment: Z79.4 for insulin, Z79.84 for oral drugs and Z79.85 for injectable non-insulin drugs. "Uncontrolled" is indexed by meaning: hyperglycemia goes to E11.65 and hypoglycemia to E11.64-.

Questions about E11.65
Is E11.65 the code for uncontrolled type 2 diabetes?
When uncontrolled means high blood sugar, yes. The Index sends uncontrolled meaning hyperglycemia, poorly controlled and out of control to E11.65. Uncontrolled meaning hypoglycemia goes to E11.64-.
Can E11.65 and E11.9 be coded together?
No. E11.9 means no complications, and hyperglycemia is a complication. Use E11.65 with any other E11 complication codes that apply.
