About H52.1

H52.1 is the ICD-10-CM diagnosis code for myopia. It belongs to category H52 (disorders of refraction and accommodation), 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 H52 (disorders of refraction and accommodation), H52.1 is specifically for myopia. Related codes cover Hypermetropia (H52.0), astigmatism (H52.2), Anisometropia and aniseikonia (H52.3), Presbyopia (H52.4), disorders of accommodation (H52.5), other disorders of refraction (H52.6) and unspecified disorder of refraction (H52.7).

To report this condition, pick the subcode that matches the documentation: H52.10 (unspecified eye), H52.11 (right eye), H52.12 (left eye) and H52.13 (bilateral).

Don't report H52.1 together with the conditions in its Excludes1 note: degenerative myopia (H44.2-).

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