What This Code Means
H40.211 is the ICD-10-CM diagnosis code for acute angle-closure glaucoma, right eye. A sudden, severe form of glaucoma in the right eye caused by a rapid increase in eye pressure, which is a medical emergency requiring immediate treatment. H40.211 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering glaucoma (h40-h42).
H40.211 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 an emergent condition; ensure documentation reflects acute presentation with symptoms like eye pain, vision changes, or redness.
