ICD-10 Code H50.682 – Extraocular muscle entrapment, unspecified, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.682 – Extraocular muscle entrapment, unspecified, left eye
What it is
H50.682 identifies entrapment of an extraocular muscle in the left eye when the specific muscle is not named. It means eye movement is mechanically restricted, often after trauma or orbital injury.
Clinical signs
Typical findings include limited eye motion, diplopia, and pain with attempted gaze. Clinical features vary; refer to documentation for the exact muscle involved and whether the restriction is confirmed on exam or imaging.
When to use this code
Use this code when the provider documents extraocular muscle entrapment in the left eye but does not specify which muscle is affected. It is also appropriate when the record confirms mechanical entrapment and laterality, yet remains nonspecific. Check documentation if the note only describes orbital fracture or eye pain without entrapment.
Do not use for
Do not use this code for generalized strabismus, nerve palsy, or simple ocular motility limitation without documented entrapment. If the record names a different eye or a specific muscle, code that documented detail instead.
Coding tip
Code the laterality and the word “entrapment” exactly as documented; if the note is vague, query for clarification.
