What This Code Means
H34.829 is the ICD-10-CM diagnosis code for venous engorgement, unspecified eye. Swelling and fullness of blood vessels in the retina (back of the eye) due to blood backup, affecting an unspecified eye. H34.829 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).
H34.829 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.
Use this code when the specific eye (right, left, or bilateral) is not documented; query the provider if eye laterality is available.
