H50.02Monocular esotropia with A pattern

H50.02 is the ICD-10-CM diagnosis code for monocular esotropia with A pattern. It belongs to category H50 (other strabismus), 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 2 subcodes must be used instead.

Within H50.0 (esotropia), H50.02 is specifically for monocular esotropia with A pattern. Related codes cover unspecified esotropia (H50.00), monocular esotropia (H50.01), monocular esotropia with V pattern (H50.03), monocular esotropia with other noncomitancies (H50.04), alternating esotropia (H50.05), alternating esotropia with A pattern (H50.06), alternating esotropia with V pattern (H50.07) and alternating esotropia with other noncomitancies (H50.08).

To report this condition, pick the subcode that matches the documentation: H50.021 (right eye) and H50.022 (left eye).

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