About coding horseshoe tear break
The ICD-10-CM code for horseshoe tear break is H33.31 (Horseshoe tear of retina without detachment).
Within H33.3, choose H33.31 (Horseshoe tear of retina without detachment) only when documentation doesn't support a more specific option: unspecified retinal break (H33.30), round hole of retina without detachment (H33.32) and multiple defects of retina without detachment (H33.33).
To report this condition, pick the subcode that matches the documentation: H33.311 (right eye), H33.312 (left eye), H33.313 (bilateral) and H33.319 (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.
