Solitary bone cyst, right pelvis

This code identifies a benign, fluid-filled lesion within the bone structure of the right pelvic girdle. These cysts are typically asymptomatic and often discovered incidentally during imaging for other conditions, though they can rarely cause pain or pathological fractures.

Apply this code when documentation confirms the presence of a solitary bone cyst located specifically in the right pelvis. This diagnosis is typically supported by imaging studies such as X-rays, CT scans, or MRI, which characterize the lesion as a simple, unicameral bone cyst.

• Ensure the documentation specifies "solitary" or "unicameral" to differentiate from other types of bone cysts or tumors.
• Verify the anatomical location is precisely the "right pelvis"; laterality is crucial for accurate coding.
• Do not use for aneurysmal bone cysts or other complex bone lesions, which have distinct codes.
