Is H50.122 an HCC code?
No. H50.122 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
H50.122 is the ICD-10-CM diagnosis code for monocular exotropia with a pattern, left eye. The left eye turns outward with an A pattern, meaning the outward deviation increases when looking downward. This combines monocular exotropia with a specific directional pattern. H50.122 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of ocular muscles, binocular movement, accommodation and refraction (h49-h52).
H50.122 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 confirms left eye involvement and A pattern characteristics.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H50.122 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify documentation confirms left eye involvement and A pattern characteristics
- •A pattern is clinically significant for treatment planning, so ensure it is explicitly documented
