H02.05Trichiasis without entropion

H02.05 is the ICD-10-CM diagnosis code for trichiasis without entropion. It belongs to category H02 (other disorders of eyelid), block H00-H05 (disorders of eyelid, lacrimal system and orbit) 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 7 subcodes must be used instead.

Within H02.0, choose H02.05 (Trichiasis without entropion) only when documentation doesn't support a more specific option: unspecified entropion of eyelid (H02.00), cicatricial entropion of eyelid (H02.01), mechanical entropion of eyelid (H02.02), senile entropion of eyelid (H02.03) and spastic entropion of eyelid (H02.04).

To report this condition, pick the subcode that matches the documentation: H02.051 (right upper eyelid), H02.052 (right lower eyelid), H02.053 (right eye, unspecified eyelid), H02.054 (left upper eyelid), H02.055 (left lower eyelid), H02.056 (left eye, unspecified eyelid) and H02.059 (unspecified eye, unspecified eyelid).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2018 (title revised).
