Unspecified night blindness

This code signifies a patient's inability to see well in low light or darkness, where the specific cause or type of night blindness has not been determined or documented. It represents a general symptom of impaired scotopic vision without further diagnostic refinement.

Use this code when documentation clearly states "night blindness" but lacks further details regarding its etiology (e.g., congenital, acquired, nutritional deficiency, or retinal disease). It is appropriate when the physician has not yet identified the underlying condition causing the nyctalopia.

• Avoid using this code if a more specific type of night blindness (e.g., congenital stationary night blindness, night blindness due to vitamin A deficiency) is documented.
• Always query the provider for more specific information if "night blindness" is the only documented finding, as a more precise code often exists.
• This code should generally be considered a temporary diagnosis while further investigation into the cause of the night blindness is underway.
