H80-H83 — Diseases of inner ear
ICD-10-CM codes H80-H83 cover diseases of inner ear, within diseases of the ear and mastoid process. The block holds 104 codes across 4 categories, of which 77 are billable and 27 are header codes that cannot be submitted on a claim.
What else to watch in H80-H83
- 38 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.
- 73 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.
