The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) is essential for medical coding and billing. Among the numerous codes, E11.65 stands out as a specific diagnosis code. This code is designated for Type 2 diabetes mellitus with hyperglycemia, a condition often associated with uncontrolled diabetes. Understanding this diagnosis code is crucial for healthcare professionals and those involved in medical coding.
ICD-10-CM code E11.65 is a billable and specific code, meaning it can be used for reimbursement purposes and precisely identifies a condition. Effective since October 1, 2015, with the current version being the 2025 edition effective October 1, 2024, E11.65 is the American ICD-10-CM version. It’s important to note that international versions of ICD-10 E11.65 might have variations.
This code falls under the broader category of Type 2 diabetes mellitus and specifically indicates the presence of hyperglycemia. Hyperglycemia, or high blood sugar, is a hallmark of uncontrolled diabetes. Synonyms for E11.65 include “Diabetes type 2 with hyperglycemia” and “Hyperglycemia due to type 2 diabetes mellitus,” all pointing to the same clinical condition.
The code history of E11.65 reveals its consistent use over the years, remaining unchanged from 2016 to the latest 2025 edition. It is positioned within a range of related ICD-10-CM codes, including those for diabetes with other complications like diabetic dermatitis (E11.620), foot ulcer (E11.621), hypoglycemia (E11.64), and other specified complications (E11.69). This context highlights the importance of accurately selecting the most appropriate code to reflect the patient’s condition for precise diagnosis and billing.
For claims with a service date on or after October 1, 2015, the use of ICD-10-CM codes, including E11.65, is mandatory. This ensures accurate recording and tracking of diabetes-related conditions and facilitates appropriate medical billing and data analysis.
