Is H50.651 an HCC code?
No. H50.651 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
H50.651 is the ICD-10-CM diagnosis code for medial rectus muscle entrapment, right eye. The medial rectus muscle in the right eye is trapped or restricted, preventing normal inward eye movement. H50.651 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).
H50.651 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.
Medial rectus entrapment may result from orbital compartment syndrome or fractures; look for related diagnoses.
