About H49.8
H49.8 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 2 subcodes must be used instead.
Within H49, choose H49.8 (Other paralytic strabismus) only when documentation doesn't support a more specific option: third [oculomotor] nerve palsy (H49.0), fourth [trochlear] nerve palsy (H49.1), sixth [abducent] nerve palsy (H49.2), total (external) ophthalmoplegia (H49.3), progressive external ophthalmoplegia (H49.4) and unspecified paralytic strabismus (H49.9).
To report this condition, pick the subcode that matches the documentation: H49.81 (syndrome) and H49.88 (strabismus).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
