Is H50.042 an HCC code?
No. H50.042 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
H50.042 is the ICD-10-CM diagnosis code for monocular esotropia with other noncomitancies, left eye. The left eye turns inward (toward the nose) with other specific patterns of eye movement restriction that don't fit standard A or V patterns. H50.042 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).
H50.042 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.
Confirm left eye involvement and that the pattern is documented as 'other noncomitancies'.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H50.042 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Confirm left eye involvement and that the pattern is documented as 'other noncomitancies'
- •Differentiate from standard A and V pattern codes by reviewing the specific movement characteristics
