H00-H05 — Disorders of eyelid, lacrimal system and orbit
ICD-10-CM codes H00-H05 cover disorders of eyelid, lacrimal system and orbit, within diseases of the eye and adnexa. The block holds 704 codes across 5 categories, of which 574 are billable and 130 are header codes that cannot be submitted on a claim.
What else to watch in H00-H05
- 396 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.
- 542 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.
