Scotoma involving central area, bilateral

This code signifies a blind spot or area of depressed vision located within the central visual field of both eyes. It indicates a bilateral impairment where the patient experiences a defect in their direct line of sight.

Apply this code when documentation explicitly states a central scotoma affecting both eyes. This is often seen in conditions like macular degeneration, optic neuropathy, or toxic amblyopia. Physician notes detailing central visual field defects confirmed by perimetry or other diagnostic tests support its use.

• Ensure the documentation specifies "central" and "bilateral" involvement; otherwise, a more specific scotoma code may be appropriate.
• Do not confuse with codes for peripheral scotoma or scotoma affecting only one eye.
• Always sequence this code after the underlying cause of the scotoma, if known and documented.
