M71.331
ICD-10-CMThis code signifies the presence of a non-inflammatory, fluid-filled sac (bursal cyst) located specifically in the right wrist. These cysts typically arise from the synovial lining of a bursa, often due to chronic irritation or trauma, and can cause localized swelling or discomfort.
Apply this code when documentation clearly indicates a diagnosis of a bursal cyst affecting the right wrist. Supporting documentation should specify the location and confirm the cystic nature, often through physical examination findings or imaging studies like ultrasound or MRI.
