H59 — Intraoperative and postprocedural complications and disorders of eye and adnexa, not elsewhere classified
ICD-10-CM codes H59 cover intraoperative and postprocedural complications and disorders of eye and adnexa, not elsewhere classified, within diseases of the eye and adnexa. The block holds 88 codes across 1 category, of which 66 are billable and 22 are header codes that cannot be submitted on a claim.
What else to watch in H59
- 30 codes are laterality-specific. They come in left and right pairs, and the pair is mutually exclusive on a single site: coding both without a bilateral code is a contradiction a scrubber should catch before the payer does.
- 45 codes are named in Medicare coverage policies. An LCD or NCD lists them as supporting medical necessity, or explicitly as not supporting it. Which applies depends on the MAC for your state.
