H90-H94 — Other disorders of ear
ICD-10-CM codes H90-H94 cover other disorders of ear, within diseases of the ear and mastoid process. The block holds 147 codes across 5 categories, of which 108 are billable and 39 are header codes that cannot be submitted on a claim.
What else to watch in H90-H94
- 56 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.
- 100 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.
