ICD-10 Code H50.671 – Superior rectus muscle entrapment, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.671 – Superior rectus muscle entrapment, right eye
What it is
This code identifies entrapment of the superior rectus muscle in the right eye, usually from trauma or orbital injury. It means the muscle is mechanically trapped, limiting normal eye movement.
Clinical signs
Typical findings include restricted upward gaze, pain with eye movement, and possible diplopia after injury. Clinical features vary; refer to documentation.
When to use this code
Use H50.671 when the provider documents superior rectus muscle entrapment specifically in the right eye. It may appear in orbital fracture or post-traumatic eye movement evaluations. Code it only when the entrapment is clearly identified in the record.
Do not use for
Do not use this code for nonspecific eye pain, general strabismus, or orbital fracture without documented muscle entrapment. Check documentation if laterality or the involved muscle is unclear.
Coding tip
Confirm both the right-sided location and the exact muscle before assigning H50.671.
