About H49.88
H49.88 is the ICD-10-CM diagnosis code for other paralytic strabismus. It belongs to category H49 (paralytic strabismus), block H49-H52 (disorders of ocular muscles, binocular movement, accommodation and refraction) and chapter 7 (diseases of the eye and adnexa). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.
Within H49.8, choose H49.88 (Other paralytic strabismus) only when documentation doesn't support a more specific option: Kearns-Sayre syndrome (H49.81).
To report this condition, pick the subcode that matches the documentation: H49.881 (right eye), H49.882 (left eye), H49.883 (bilateral) and H49.889 (unspecified eye).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
