ICD-10 Code H50.672 – Superior rectus muscle entrapment, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.672 – Superior rectus muscle entrapment, left eye
What it is
H50.672 identifies entrapment of the superior rectus muscle in the left eye. Use it when documentation shows the muscle is mechanically trapped, usually after trauma or orbital injury.
Clinical signs
Typical findings include restricted upgaze, pain with eye movement, and possible diplopia. Clinical features vary; refer to documentation for the exact injured structure and laterality.
When to use this code
Use this code when the provider specifically documents superior rectus muscle entrapment in the left eye. It may appear in orbital fracture evaluations, postoperative notes, or trauma assessments. If the record only says “eye muscle entrapment,” check documentation for the named muscle and side.
Do not use for
Do not use this code for nonspecific strabismus, eye movement pain without entrapment, or right-eye involvement. If the chart does not identify the superior rectus muscle or left eye, check documentation.
Coding tip
Match the muscle and laterality exactly; entrapment codes are specific and should not be assigned from vague orbital injury wording alone.
