H49-H52 — Disorders of ocular muscles, binocular movement, accommodation and refraction
ICD-10-CM codes H49-H52 cover disorders of ocular muscles, binocular movement, accommodation and refraction, within diseases of the eye and adnexa. The block holds 203 codes across 4 categories, of which 150 are billable and 53 are header codes that cannot be submitted on a claim.
Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
- nystagmus and other irregular eye movements (H55)
What else to watch in H49-H52
- 74 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.
- 118 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.
