Is H17.829 an HCC code?
No. H17.829 is a billable ICD-10-CM code but does not map to any HCC category in V28, V24, ESRD, or RxHCC.
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
H17.829 is the ICD-10-CM diagnosis code for peripheral opacity of cornea, unspecified eye. A cloudy or opaque area on the outer edge of the cornea (the clear front part of the eye) that affects vision, but the specific eye is not documented. This condition can result from injury, infection, or other eye diseases. H17.829 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of sclera, cornea, iris and ciliary body (h15-h22).
H17.829 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 only when the documentation does not specify whether the condition affects the right eye, left eye, or both eyes; if laterality is documented, use the more specific codes H17.821 (right eye) or H17.822 (left eye).
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H17.829 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code only when the documentation does not specify whether the condition affects the right eye, left eye, or both eyes; if laterality is documented, use the more specific codes H17.821 (right eye) or H17.822 (left eye)
- •Verify whether the opacity is truly peripheral (outer edge) versus central; peripheral opacities may have different clinical significance and treatment approaches than central corneal opacities
