Other paralytic strabismus, right eye

This code signifies a paralysis or paresis of one or more extraocular muscles affecting the right eye, leading to impaired eye movement and misalignment. It encompasses forms of paralytic strabismus not otherwise specified or classified under other H49.x codes. The condition results in diplopia, compensatory head postures, and reduced visual acuity.

Assign this code when documentation indicates paralytic strabismus specifically affecting the right eye, and the etiology or specific muscle involvement does not fit more precise codes (e.g., third, fourth, or sixth nerve palsy). This code is appropriate when the physician's diagnosis explicitly states "other paralytic strabismus, right eye" or similar phrasing after ruling out more specific causes.

• Ensure the documentation clearly specifies the right eye involvement.
• Differentiate from non-paralytic strabismus (H50.xx) and other forms of paralytic strabismus with more specific codes (e.g., H49.0x, H49.1x, H49.2x).
• Always look for an underlying cause of the paralytic strabismus, which may require an additional code.
