Scotoma involving central area, unspecified eye

This code describes a blind spot or area of depressed vision located within the central part of the visual field, affecting an unspecified eye. This central scotoma can manifest as a partial or complete loss of vision in the affected area, often impacting reading or fine detail perception.

Use this code when documentation clearly indicates a central scotoma without specifying laterality (left or right eye). This diagnosis is often made during an ophthalmological examination, such as a visual field test. Supporting documentation should include findings from visual field testing or a physician's direct observation of a central blind spot.

• Do not use this code if the laterality of the central scotoma is known; instead, select a more specific code (H53.411, H53.412, H53.413).
• Distinguish central scotoma from other types of scotoma (e.g., paracentral, arcuate) which have different code assignments.
• Always review the physician's documentation for the specific location and laterality of the scotoma to ensure the most precise code is selected.
