About H52

H52 is the ICD-10-CM diagnosis code for disorders of refraction and accommodation. 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 8 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: H52.0 (Hypermetropia), H52.1 (myopia), H52.2 (astigmatism), H52.3 (aniseikonia), H52.4 (Presbyopia), H52.5 (accommodation), H52.6 (refraction) and H52.7 (refraction).

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