What This Code Means
H50.621 is the ICD-10-CM diagnosis code for inferior oblique muscle entrapment, right eye. A condition affecting the right eye where the inferior oblique muscle is trapped or restricted, limiting normal eye movement. H50.621 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).
H50.621 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.
Inferior oblique muscle entrapment is a restrictive condition; always specify laterality (right eye in this code).
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H50.621 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
