About H53.02

H53.02 is the ICD-10-CM diagnosis code for refractive amblyopia. It belongs to category H53 (visual disturbances), block H53-H54 (visual disturbances and blindness) 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 H53.0 (amblyopia ex anopsia), H53.02 is specifically for refractive amblyopia. Related codes cover unspecified amblyopia (H53.00), deprivation amblyopia (H53.01), Strabismic amblyopia (H53.03) and amblyopia suspect (H53.04).

To report this condition, pick the subcode that matches the documentation: H53.021 (right eye), H53.022 (left eye), H53.023 (bilateral) and H53.029 (unspecified eye).

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