What This Code Means
H47.232 is the ICD-10-CM diagnosis code for glaucomatous optic atrophy, left eye. This condition describes permanent damage to the optic nerve in the left eye caused by glaucoma, where the nerve tissue has deteriorated and shrunk. This damage results in vision loss and cannot be reversed. H47.232 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of optic nerve and visual pathways (h46-h47).
H47.232 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.
Verify documentation specifies 'left eye' to ensure correct laterality coding; do not assume if only one eye is mentioned.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H47.232 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
