Other paralytic strabismus, bilateral

This code signifies a type of paralytic strabismus affecting both eyes, where the misalignment is due to impaired extraocular muscle function from nerve palsy or muscle weakness, but does not fit into more specific categories of paralytic strabismus. It indicates a bilateral ocular motility disorder resulting in diplopia or other visual disturbances.

Use this code when documentation specifies paralytic strabismus affecting both eyes, and the specific type (e.g., third, fourth, or sixth nerve palsy) is not identified or is atypical. This code is appropriate when the etiology of the bilateral paralytic strabismus is documented as "other" or unspecified, but clearly not congenital or due to specific cranial nerve palsies.

• Ensure documentation clearly states "bilateral" involvement of the paralytic strabismus.
• Avoid using this code if a more specific paralytic strabismus code (e.g., H49.0-H49.3) can be assigned based on the affected cranial nerve.
• Consider sequencing this code with an underlying cause if known and documented, such as a neurological condition or injury.
