H15.021 ICD-10-CM Code: Brawny scleritis, right eye

H15.021 is the ICD-10-CM diagnosis code for brawny scleritis, right eye. Brawny scleritis is a severe inflammation of the white part of the eye (sclera) that causes swelling, hardening, and a characteristic brownish discoloration. This code specifically refers to this condition affecting the right eye. H15.021 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).

H15.021 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 laterality is documented in the medical record - this code is specific to the right eye, so ensure the provider has clearly indicated which eye is affected.
