What This Code Means
H59.321 is the ICD-10-CM diagnosis code for postprocedural hemorrhage of right eye and adnexa following other procedure. Bleeding in or around the right eye that occurred after a non-eye surgical or medical procedure. H59.321 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering intraoperative and postprocedural complications and disorders of eye and adnexa, not elsewhere classified (h59).
H59.321 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28 or V24 community payment models, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
This code is for complications following non-ophthalmic procedures - verify the procedure was not eye surgery.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for H59.321 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
