Other cyst of bone, unspecified shoulder

This code signifies the presence of a non-specific bone cyst located in an unspecified shoulder. These are typically benign, fluid-filled or semi-solid lesions within the bone, distinct from malignant tumors or infectious processes. The "other" classification indicates it's not a solitary bone cyst, aneurysmal bone cyst, or fibrous dysplasia.

Use this code when documentation confirms a bone cyst in the shoulder, but the specific type of cyst is not further identified (e.g., "bone cyst, shoulder" or "cystic lesion of humerus/scapula, etiology unknown"). This code is appropriate when laterality of the shoulder is not specified in the medical record.

• Avoid using this code if a more specific type of bone cyst (e.g., solitary bone cyst, aneurysmal bone cyst) or a more precise anatomical location within the shoulder is documented.
• Query the provider for laterality (left, right) if not documented, as more specific codes exist for specified shoulders.
• Ensure the documentation clearly states "cyst of bone" to differentiate from soft tissue cysts.
