Other paralytic strabismus, left eye

This code signifies a type of paralytic strabismus affecting the left eye, where the specific muscle or nerve involvement is not otherwise specified or falls outside of more defined categories. It indicates a misalignment of the left eye due to paralysis or weakness of one or more extraocular muscles, resulting in impaired eye movement and binocular vision.

Use this code when documentation clearly indicates paralytic strabismus of the left eye, but the specific etiology (e.g., third, fourth, or sixth nerve palsy) is not identified or is described as "other." This code is appropriate when the physician's notes confirm left eye involvement and rule out more specific paralytic strabismus diagnoses.

• Ensure documentation specifies "left eye" and "paralytic strabismus" without a more precise cause.
• Distinguish from non-paralytic strabismus (H50.-) and other specified paralytic strabismus (H49.0-H49.81).
• Always query the provider for a more specific diagnosis if the documentation is unclear regarding the underlying cause of the paralysis.
