Chapter 7: Diseases of the Eye and Adnexa
ICD-10 to ICD-11 crosswalk mappings for codes H00-H59
258 ICD-10 codes in this chapter have ICD-11 crosswalk mappings from the WHO.
Covers eye conditions including cataracts, glaucoma, macular degeneration, diabetic retinopathy, conjunctivitis, and refractive disorders. Age-related macular degeneration and glaucoma are leading causes of vision impairment, and these codes are essential for ophthalmology billing.
