What This Code Means
H50.612 is the ICD-10-CM diagnosis code for brown's sheath syndrome, left eye. A condition affecting the left eye where the superior oblique muscle is restricted by an abnormal fibrous tissue sheath, limiting eye movement. H50.612 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).
H50.612 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 restrictive condition of the superior oblique muscle; specify laterality (left eye in this code).
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H50.612 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Brown's sheath syndrome is a restrictive condition of the superior oblique muscle; specify laterality (left eye in this code)
