What This Code Means
H50.632 is the ICD-10-CM diagnosis code for inferior rectus muscle entrapment, left eye. The inferior rectus muscle in the left eye is trapped or restricted, preventing normal downward eye movement. H50.632 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).
H50.632 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.
This code is specific to the left eye; ensure documentation clearly indicates left eye involvement.
