Vogt-Koyanagi syndrome, bilateral

This code represents Vogt-Koyanagi-Harada (VKH) syndrome affecting both eyes. VKH is a rare, multisystem autoimmune disorder characterized by chronic, bilateral panuveitis, often accompanied by neurological, auditory, and integumentary manifestations.

Apply this code when documentation explicitly states a diagnosis of Vogt-Koyanagi-Harada syndrome with bilateral ocular involvement. Supporting clinical notes should detail the characteristic uveitis and may include mention of associated symptoms like headache, tinnitus, or vitiligo.

• Ensure the documentation specifies "bilateral" involvement; otherwise, a more general or unspecified laterality code may be appropriate.
• Do not confuse with other forms of uveitis; VKH has distinct systemic features.
• Code any associated neurological, auditory, or integumentary manifestations separately.
