About H51

H51 is the ICD-10-CM diagnosis code for other disorders of binocular movement. 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 5 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: H51.0 (gaze), H51.1 (excess), H51.2 (ophthalmoplegia), H51.8 (movement) and H51.9 (movement).

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