What This Code Means
H18.219 is the ICD-10-CM diagnosis code for corneal edema secondary to contact lens, unspecified eye. Swelling of the cornea (the clear front part of the eye) caused by contact lens wear, affecting an unspecified eye. H18.219 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).
H18.219 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.
Verify which eye is affected; if documented, use the specific laterality code (H18.211 for right, H18.212 for left, H18.213 for bilateral).
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H18.219 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
