What This Code Means
H31.311 is the ICD-10-CM diagnosis code for expulsive choroidal hemorrhage, right eye. A sudden, severe bleeding inside the choroid layer (the blood vessel layer beneath the retina) of the right eye that can cause the eye contents to be pushed outward. This is a serious eye emergency that typically occurs during or after eye surgery. H31.311 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of choroid and retina (h30-h36).
H31.311 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.
This code is specific to the right eye; verify laterality in the medical record and use H31.312 for left eye or H31.313 for bilateral cases.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H31.311 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
