ICD-10 Code H50.679 – Superior rectus muscle entrapment, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.679 – Superior rectus muscle entrapment, unspecified eye
What it is
Use this code for documented entrapment of the superior rectus muscle when the eye is not specified. It describes a mechanical restriction involving the muscle, not a general eye pain or trauma code.
Clinical signs
Clinical features vary; refer to documentation. Typical notes may describe restricted eye movement, diplopia, or abnormal gaze alignment consistent with muscle entrapment.
When to use this code
Assign H50.679 when the provider clearly documents superior rectus muscle entrapment and does not identify right or left eye. Use it for encounters where the diagnosis is established or being followed. If the record only mentions suspected entrapment, check documentation before coding.
Do not use for
Do not use this code for nonspecific strabismus, general orbital injury, or other extraocular muscle disorders without documented superior rectus entrapment. Check documentation if the eye laterality is specified.
Coding tip
Confirm both the muscle involved and the unspecified-eye wording before assigning H50.679.
