What This Code Means
H18.441 is the ICD-10-CM diagnosis code for keratomalacia, right eye. Softening and melting of the cornea in the right eye, typically caused by severe dryness, infection, or chemical injury, which can lead to vision loss or blindness if untreated. H18.441 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of sclera, cornea, iris and ciliary body (h15-h22).
H18.441 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Keratomalacia is a serious condition requiring urgent treatment; document the underlying etiology (vitamin A deficiency, severe dry eye, infection, or chemical burn).
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H18.441 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
