H15-H22 — Disorders of sclera, cornea, iris and ciliary body
ICD-10-CM codes H15-H22 cover disorders of sclera, cornea, iris and ciliary body, within diseases of the eye and adnexa. The block holds 646 codes across 7 categories, of which 497 are billable and 149 are header codes that cannot be submitted on a claim.
What else to watch in H15-H22
- 238 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.
- 480 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.
