About H50

H50 is the ICD-10-CM diagnosis code for other strabismus. It belongs to 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 9 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: H50.0 (esotropia), H50.1 (exotropia), H50.2 (strabismus), H50.3 (heterotropia), H50.4 (heterotropia), H50.5 (heterophoria), H50.6 (strabismus), H50.8 (strabismus) and 1 more.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
