About H53.00
H53.00 is the ICD-10-CM diagnosis code for unspecified 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, choose H53.00 (Unspecified amblyopia) only when documentation doesn't support a more specific option: deprivation amblyopia (H53.01), refractive amblyopia (H53.02), Strabismic amblyopia (H53.03) and amblyopia suspect (H53.04).
To report this condition, pick the subcode that matches the documentation: H53.001 (right eye), H53.002 (left eye), H53.003 (bilateral) and H53.009 (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.
