Vogt-Koyanagi syndrome, left eye

This code identifies Vogt-Koyanagi-Harada (VKH) syndrome affecting the left eye. VKH syndrome is a rare, multisystem autoimmune disorder characterized by chronic, bilateral panuveitis with associated neurological, auditory, and integumentary manifestations. This specific code indicates the ocular involvement is present in the left eye.

Use this code when documentation confirms a diagnosis of Vogt-Koyanagi-Harada syndrome with specific involvement of the left eye. Supporting clinical notes should detail the characteristic ocular inflammation (e.g., panuveitis, serous retinal detachments) and may also mention associated extraocular findings such as headache, tinnitus, or vitiligo.

• Ensure the laterality is accurately documented as "left eye" to support this specific code.
• Do not use this code for unspecified laterality; instead, refer to H20.829.
• Code any associated neurological, auditory, or integumentary manifestations separately.
