What This Code Means
M85.441 is the ICD-10-CM diagnosis code for solitary bone cyst, right hand. A fluid-filled cavity or hollow space in the bones of the right hand that is not associated with other bone conditions. M85.441 sits in the ICD-10-CM chapter for diseases of the musculoskeletal system and connective tissue (m00-m99), within the section covering disorders of bone density and structure (m80-m85).
M85.441 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.
Specify which hand bone(s) are affected (carpal, metacarpal, or phalanges) in documentation when possible.
