ICD-10 Code H49.88 – Other paralytic strabismus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H49.88 – Other paralytic strabismus
What it is
H49.88 identifies paralytic strabismus caused by weakness or paralysis of an extraocular muscle, but not one of the more specifically named paralytic strabismus codes. Use it when documentation states an other or unspecified paralytic deviation.
Clinical signs
Typical findings include misaligned eyes, diplopia, and limited movement in the affected gaze direction. Clinical features vary; refer to documentation for the nerve or muscle involved and any recorded exam findings.
When to use this code
Use H49.88 when the provider documents paralytic strabismus and does not specify a more exact subtype. It may apply when the note describes ocular motility weakness, but the cause or exact muscle pattern is not fully identified. Check documentation before assigning it.
Do not use for
Do not use this code for nonparalytic strabismus, such as accommodative or concomitant forms. Also avoid it when the record supports a more specific paralytic strabismus code.
Coding tip
Look for the exact provider wording; if the paralysis is specified, code the more detailed diagnosis instead of H49.88.
