Is H17.812 an HCC code?

What This Code Means
H17.812 is the ICD-10-CM diagnosis code for minor opacity of cornea, left eye. A small cloudy spot on the cornea of the left eye that causes minimal vision problems. H17.812 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).
H17.812 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 the opacity is documented as minor and not in the central cornea before assigning this code.

Coding Tips
- •Verify the opacity is documented as minor and not in the central cornea before assigning this code
