What This Code Means
H18.722 is the ICD-10-CM diagnosis code for corneal staphyloma, left eye. A condition where the cornea of the left eye develops a localized bulge or scar-like protrusion, typically resulting from previous injury or disease. H18.722 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).
H18.722 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.
Staphyloma is a permanent bulging of the cornea; document whether it resulted from trauma, infection, or other cause if available.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H18.722 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Staphyloma is a permanent bulging of the cornea; document whether it resulted from trauma, infection, or other cause if available
