Other cyst of bone, right shoulder

This code signifies the presence of a non-neoplastic, fluid-filled or semi-solid sac within the bone of the patient's right shoulder. These cysts are typically benign and can be asymptomatic or cause localized pain and swelling. They are distinct from malignant bone tumors or infectious processes.

Apply this code when documentation specifies an "other cyst of bone" located in the right shoulder, such as a simple bone cyst, unicameral bone cyst, or aneurysmal bone cyst, that doesn't fit more specific ICD-10-CM categories. Supporting documentation should include imaging reports (X-ray, MRI, CT) confirming the presence and location of the cyst, along with a physician's diagnostic statement.

• Ensure the documentation clearly specifies "right shoulder" to avoid laterality errors.
• Distinguish this from specific types of bone cysts with their own codes (e.g., M85.4- for solitary bone cyst).
• Always review pathology reports if a biopsy or excision was performed to confirm the benign nature and specific type of cyst.
