H21.213
BillableDegeneration of chamber angle, bilateral
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
This condition involves the deterioration of the drainage system (chamber angle) in both eyes, which can affect how fluid drains from the eye and potentially lead to increased eye pressure. It is a structural problem in the eye that may develop over time.
Coding Tips
- •Verify that the condition is documented as bilateral (affecting both eyes) before assigning this code; if only one eye is affected, use the unilateral code H21.211 instead
- •This code is typically used in ophthalmology records and may be associated with glaucoma risk; review clinical documentation to determine if additional glaucoma codes should be assigned
