ICD-10 Code H49.883 – Other paralytic strabismus, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H49.883 – Other paralytic strabismus, bilateral
What it is
This code identifies bilateral paralytic strabismus not otherwise specified by a more exact subtype. It means eye misalignment caused by impaired extraocular muscle or nerve function affecting both eyes.
Clinical signs
Patients may have diplopia, limited eye movement, or abnormal head posture. Clinical features vary; refer to documentation for the specific cranial nerve or muscle involvement.
When to use this code
Use H49.883 when the provider documents paralytic strabismus affecting both eyes and does not name a more specific paralytic strabismus code. This is appropriate when the record supports bilateral involvement but the exact cause or nerve is not fully specified. Check documentation if the diagnosis is uncertain.
Do not use for
Do not use this code for nonparalytic strabismus or for unilateral paralytic strabismus. If the chart identifies a more specific paralytic strabismus diagnosis, code that instead.
Coding tip
Confirm bilateral involvement and the provider’s exact wording before assigning H49.883.
