H55-H57Other disorders of eye and adnexa

ICD-10-CM codes H55-H57 cover other disorders of eye and adnexa, within diseases of the eye and adnexa. The block holds 43 codes across 2 categories, of which 33 are billable and 10 are header codes that cannot be submitted on a claim.

What else to watch in H55-H57

  • 8 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.
  • 32 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.
