Family history of blindness and visual loss

This code indicates a patient has a family history of conditions leading to blindness or significant visual impairment. It signifies a genetic predisposition or familial pattern of severe vision loss, which may influence a patient's risk assessment or screening recommendations.

Apply this code when a patient reports a close relative (e.g., parent, sibling, grandparent) has a history of blindness or a specific condition causing severe visual loss. This is particularly relevant when evaluating a patient for visual symptoms, conducting preventative screenings, or managing conditions with a known hereditary component affecting vision.

• Always document the specific family member and the condition causing blindness or visual loss when available.
• Do not use this code if the patient themselves has a diagnosis of blindness or visual loss; instead, code the patient's specific condition.
• This code is for informational purposes and typically used as a secondary diagnosis to support medical necessity for further testing or monitoring.
