ICD-10 Code H05.82 – Myopathy of extraocular muscles (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.82 – Myopathy of extraocular muscles
What it is
H05.82 identifies a disorder affecting the extraocular muscles, the muscles that move the eyes. Use it when documentation states myopathy of these muscles and the condition is not better described by another diagnosis.
Clinical signs
Typical findings include impaired eye movement, diplopia, or restricted gaze related to extraocular muscle dysfunction. Clinical features vary; refer to documentation for the specific muscle involvement and cause.
When to use this code
Use H05.82 when the provider documents myopathy of the extraocular muscles as the diagnosis. It may apply when the record describes weakness or dysfunction of the eye muscles without a more specific coded etiology. Check documentation if the note instead names a different orbital or neurologic disorder.
Do not use for
Do not use this code for general eye movement problems without documented extraocular muscle myopathy. Avoid it when the condition is better classified as a neurologic, inflammatory, traumatic, or other orbital disorder.
Coding tip
Code from the provider’s exact wording and query if the record only says diplopia, ophthalmoplegia, or eye muscle weakness.
