ICD-10 Code H50.412 – Cyclotropia, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.412 – Cyclotropia, left eye
What it is
Cyclotropia is a form of ocular misalignment where the left eye is rotated around its visual axis. Use this code when documentation identifies cyclotropia specifically in the left eye.
Clinical signs
Clinical features may include torsional eye deviation, diplopia, or abnormal head posture. Findings can vary; refer to documentation and any ophthalmologic exam describing left-eye cyclotropia.
When to use this code
Use H50.412 when the provider documents cyclotropia affecting the left eye, whether as a primary diagnosis or a noted finding. Code it from specialist assessment, operative notes, or problem lists when the laterality is clearly stated. If the record does not specify left eye, check documentation.
Do not use for
Do not use this code for unspecified cyclotropia, other types of strabismus, or right-eye involvement. If the diagnosis is unclear or laterality is missing, check documentation before coding.
Coding tip
Always confirm laterality and the exact term “cyclotropia” in the record before assigning H50.412.
