About H53.04

H53.04 is the ICD-10-CM diagnosis code for amblyopia suspect. 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), H53.04 is specifically for amblyopia suspect. Related codes cover unspecified amblyopia (H53.00), deprivation amblyopia (H53.01), refractive amblyopia (H53.02) and Strabismic amblyopia (H53.03).

To report this condition, pick the subcode that matches the documentation: H53.041 (right eye), H53.042 (left eye), H53.043 (bilateral) and H53.049 (unspecified eye).

It was added in FY2017, effective October 1, 2016.
