H25-H28 — Disorders of lens
ICD-10-CM codes H25-H28 cover disorders of lens, within diseases of the eye and adnexa. The block holds 156 codes across 4 categories, of which 119 are billable and 37 are header codes that cannot be submitted on a claim.
What else to watch in H25-H28
- 54 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.
- 116 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.
