What you can do
ICD-Code E11* is a non-billable ICD-10 code used for healthcare diagnosis reimbursement of Type 2 Diabetes Mellitus. Its corresponding ICD-9 code is 250. Code I10 is the diagnosis code used for Type 2 Diabetes Mellitus.
ICD-10 Code Z79. 4, Long-term (current) use of insulin should be assigned to indicate that the patient uses insulin for Type 2 diabetes mellitus (Category E11* codes). Z79. 4 should NOT be used for Type 1 diabetes mellitus (Category E10* codes).
E10, Type 1 diabetes mellitus. E11, Type 2 diabetes mellitus. E13, Other specified diabetes mellitus.
E11. 69 - Type 2 diabetes mellitus with other specified complication. ICD-10-CM.
ICD-Code I10 is a billable ICD-10 code used for healthcare diagnosis reimbursement of Essential (Primary) Hypertension. Its corresponding ICD-9 code is 401.
5A11 Type 2 diabetes mellitus - ICD-11 MMS.
The main difference between the type 1 and type 2 diabetes is that type 1 diabetes is a genetic condition that often shows up early in life, and type 2 is mainly lifestyle-related and develops over time. With type 1 diabetes, your immune system is attacking and destroying the insulin-producing cells in your pancreas.

E11. 9 - Type 2 diabetes mellitus without complications. ICD-10-CM.
Type 2 diabetes mellitus with other specified complication E11. 69 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM E11. 69 became effective on October 1, 2021.
The incorrect portion of the response came as an aside at the end, where it was stated that “it would be redundant to assign codes for both diabetic nephropathy (E11. 21) and diabetic chronic kidney disease (E11. 22), as diabetic chronic kidney disease is a more specific condition.” It is true you wouldn't code both.
ICD10 Codes (E11) Type 2 diabetes mellitus includes insulin resistant diabetes (mellitus), diabetes (mellitus) due to insulin secretory defect and diabetes NOS.
E11.311 Type 2 diabetes mellitus with unspecified diabetic retinopathy with macular edema.
E11.49 Type 2 diabetes mellitus with other diabetic neurological complication.
For gestational diabetes (diabetes that occurs during pregnancy) women should be assigned a code under the 024.4 subheading and not any other codes under the 024 category.
If the type of diabetes that the patient has is not documented in the medical record, E11 codes for type 2 diabetes should be used as a default. If the medical record doesn’t say what type of diabetes the patient has but indicates that the patient uses insulin, the Type 2 diabetes codes should also be used.
The “unspecified” codes can be used when not enough information is known to give a more specific diagnosis; in that case, “unspecified” is technically more accurate than a more specific but as yet unconfirmed diagnosis.
