What This Code Means
H31.312 is the ICD-10-CM diagnosis code for expulsive choroidal hemorrhage, left eye. Expulsive choroidal hemorrhage in the left eye is a serious condition where bleeding in the choroid layer causes sudden expansion that can push the retina forward, potentially occurring during eye surgery. H31.312 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).
H31.312 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 is a surgical emergency; document the clinical context and any surgical procedures performed.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H31.312 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
