Is H50.611 an HCC code?
No. H50.611 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
H50.611 is the ICD-10-CM diagnosis code for brown's sheath syndrome, right eye. Brown's sheath syndrome is a rare eye movement disorder where the superior oblique tendon becomes restricted or stuck, limiting the eye's ability to move upward and inward. This condition affects the right eye and can cause double vision or difficulty with certain eye movements. H50.611 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).
H50.611 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.
Brown's sheath syndrome is a specific strabismus disorder; ensure documentation clearly identifies which eye is affected (right eye = H50.611, left eye = H50.612, bilateral = H50.613).

Coding Tips
- •Brown's sheath syndrome is a specific strabismus disorder; ensure documentation clearly identifies which eye is affected (right eye = H50.611, left eye = H50.612, bilateral = H50.613)
- •This condition may require additional codes for any resulting strabismus or diplopia; review the complete clinical documentation to determine if additional eye movement or vision-related codes are needed
