What This Code Means
H40.029 is the ICD-10-CM diagnosis code for open angle with borderline findings, high risk, unspecified eye. A condition where the eye's drainage angle is open but shows borderline signs of glaucoma with high risk of vision loss, affecting an unspecified eye. H40.029 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering glaucoma (h40-h42).
H40.029 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 only when the specific eye is not documented in the clinical record.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H40.029 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
