ICD-10 Code H05.822 – Myopathy of extraocular muscles, left orbit (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.822 – Myopathy of extraocular muscles, left orbit
What it is
This code identifies a disorder affecting the left eye’s extraocular muscles, which control eye movement. Use it when documentation specifically states myopathy of the extraocular muscles in the left orbit.
Clinical signs
Clinical features may include limited eye movement, diplopia, or misalignment of the eyes. Clinical features vary; refer to documentation.
When to use this code
Use H05.822 when the provider documents myopathy involving the extraocular muscles of the left orbit. It is appropriate when the record localizes the condition to the left side and does not describe a more specific underlying cause. Check documentation if the note only mentions eye movement problems without a confirmed diagnosis.
Do not use for
Do not use this code for nonspecific diplopia, general strabismus, or right-sided or bilateral extraocular muscle disorders. If the record identifies another cause or location, code that condition instead.
Coding tip
Confirm laterality and the exact provider diagnosis before assigning H05.822.
