Other cyst of bone, left shoulder

This code signifies the presence of a non-neoplastic, fluid-filled or semi-solid sac within the bone structure of the patient's left shoulder. These cysts are typically benign and can be asymptomatic or cause localized pain and swelling.

Use this code when documentation clearly indicates a diagnosis of a bone cyst in the left shoulder that is not otherwise specified as an aneurysmal bone cyst, solitary bone cyst, or osteofibrous dysplasia. Supporting documentation would include imaging reports (X-ray, MRI, CT) confirming the presence and location of the cyst, and physician notes detailing the diagnosis.

• Ensure the documentation specifies "other cyst" and not a more specific type of bone cyst, which would have a different code.
• Verify laterality; this code is specifically for the left shoulder.
• Do not use this code for malignant bone tumors or metastatic disease to the bone.
