ICD-10 Code H50.811 – Duane’s syndrome, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.811 – Duane’s syndrome, right eye
What it is
H50.811 identifies Duane’s syndrome affecting the right eye. It is a congenital eye movement disorder in which the right eye has limited horizontal motion because of abnormal control of the eye muscles.
Clinical signs
Common findings include restricted abduction, limited adduction, and globe retraction on attempted adduction. Clinical features vary; refer to documentation for the specific subtype and laterality.
When to use this code
Use this code when the record clearly documents Duane’s syndrome in the right eye. It fits specialist notes, problem lists, or referral documentation that specify right-sided involvement. If laterality is not stated, check documentation before coding.
Do not use for
Do not use it for nonspecific strabismus, eye movement limitation from trauma, or bilateral Duane syndrome. If the record does not confirm right-eye involvement, check documentation.
Coding tip
Always verify laterality and whether the provider documents Duane syndrome explicitly before assigning H50.811.
