Kearns-Sayre syndrome, right eye

This code identifies Kearns-Sayre syndrome affecting the right eye. Kearns-Sayre syndrome is a rare, progressive neuromuscular disorder characterized by external ophthalmoplegia, pigmentary retinopathy, and cardiac conduction defects, among other systemic manifestations.

Use this code when documentation specifies Kearns-Sayre syndrome with involvement of the right eye. This diagnosis is typically supported by findings such as progressive external ophthalmoplegia, ptosis, and pigmentary retinopathy noted during an ophthalmologic examination, often in conjunction with systemic symptoms.

• Ensure the documentation clearly specifies "right eye" involvement for accurate laterality.
• Code any associated systemic manifestations of Kearns-Sayre syndrome, such as cardiac conduction disorders (e.g., I45.8) or cerebellar ataxia (e.g., G11.9), as secondary diagnoses.
• Do not confuse with other forms of chronic progressive external ophthalmoplegia (CPEO) if Kearns-Sayre syndrome is not explicitly diagnosed.
