ICD-10 Code H50.67 – Superior rectus muscle entrapment (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.67 – Superior rectus muscle entrapment
What it is
This code identifies entrapment of the superior rectus muscle, usually meaning the muscle is trapped or restricted by surrounding tissue or fracture-related injury. It refers to a specific mechanical problem affecting eye movement.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see restricted upward gaze, pain with eye movement, diplopia, or signs of orbital trauma when the muscle is mechanically limited.
When to use this code
Use this code when the provider documents superior rectus muscle entrapment as the diagnosis. It may apply after orbital injury, surgery, or imaging-supported restriction of the muscle. If the record only says eye movement limitation without entrapment, check documentation.
Do not use for
Do not use it for nonspecific diplopia, general strabismus, or eye pain without documented entrapment. If the note describes another extraocular muscle or an orbital fracture without muscle trapping, use the documented condition instead.
Coding tip
Code from explicit provider documentation of entrapment; do not infer it from trauma or restricted gaze alone.
