Family history of diabetes mellitus

This code indicates a patient's biological family history of diabetes mellitus. It signifies that one or more immediate blood relatives (e.g., parents, siblings, children) have been diagnosed with any form of diabetes. This information is crucial for assessing a patient's genetic predisposition and risk factors for developing the condition.

Assign this code when a patient reports a family history of diabetes during a medical encounter, even if the patient themselves does not currently have diabetes. It is commonly used in preventative care, annual physicals, or when evaluating a patient for symptoms that could be related to metabolic disorders. This code supports medical necessity for screenings or counseling related to diabetes risk.

• Always confirm the specific type of diabetes in the family history if possible, though this code is general for any diabetes.
• Do not use this code if the patient themselves has a personal history or current diagnosis of diabetes; use the appropriate diabetes code instead.
• This code is a secondary diagnosis and should be reported in conjunction with other codes explaining the reason for the encounter or the patient's current health status.
