ICD-10 Code H50.22 – Vertical strabismus, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.22 – Vertical strabismus, left eye
What it is
H50.22 identifies a vertical misalignment of the left eye, where the eye sits higher or lower than expected. Use it when documentation specifically states vertical strabismus affecting the left eye.
Clinical signs
Typical findings include vertical eye deviation, misalignment on cover testing, and possible diplopia or abnormal head posture. Clinical features vary; refer to documentation.
When to use this code
Use H50.22 when the provider documents vertical strabismus of the left eye, including congenital or acquired cases if no more specific code is given. It applies when the record clearly identifies the left eye as the involved eye. If laterality or type is unclear, check documentation before coding.
Do not use for
Do not use this code for horizontal strabismus, unspecified eye involvement, or general ocular misalignment without vertical deviation. Check documentation if the note describes diplopia alone or another eye movement disorder.
Coding tip
Confirm laterality and vertical direction in the assessment or ophthalmology note before assigning H50.22.
