Family history of blindness or visual loss

This code indicates a patient's family history of blindness or significant visual impairment. It signifies a genetic predisposition or familial pattern of severe vision loss that may impact the patient's own risk or management. This is not a current condition for the patient but a relevant historical factor.

Apply this code when documentation explicitly states a family history of blindness or visual loss, such as for a parent, sibling, or grandparent. It is often used in ophthalmology, optometry, or genetic counseling settings to explain the rationale for specific screenings, monitoring, or risk assessments.

• Ensure the documentation clearly specifies "family history" and not a personal history of visual impairment.
• Do not use this code if the patient themselves has a diagnosis of blindness; use a more specific code for the patient's condition.
• This code is typically a secondary diagnosis, providing context for the patient's primary reason for the encounter.
