H15.031 ICD-10-CM Code: Posterior scleritis, right eye

H15.031 is the ICD-10-CM diagnosis code for posterior scleritis, right eye. Posterior scleritis is inflammation of the back part of the white of the eye (sclera) on the right side. This condition can cause eye pain, vision problems, and swelling in the tissues behind the eye. H15.031 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).

H15.031 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 as right eye (H15.031) versus left eye (H15.032) or bilateral (H15.033) to ensure accurate code selection.
