ICD-10 Code H50.68 – Extraocular muscle entrapment, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.68 – Extraocular muscle entrapment, unspecified
What it is
H50.68 identifies extraocular muscle entrapment when the affected muscle is not specified. It indicates mechanical trapping of an eye muscle, usually after orbital injury or surgery, causing restricted eye movement.
Clinical signs
Common findings include limited gaze, pain with eye movement, diplopia, and possible nausea or bradycardia in orbital trauma. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record documents entrapment of an extraocular muscle but does not name the specific muscle. It is appropriate for postoperative or traumatic cases where the clinician confirms muscle trapping. If the note identifies the exact muscle, code that more specific diagnosis instead.
Do not use for
Do not use this code for simple muscle strain, general diplopia, or unspecified orbital fracture without documented entrapment. Check documentation.
Coding tip
Assign H50.68 only when the provider clearly documents entrapment; otherwise, query for clarification.
