Solitary bone cyst, left pelvis

This code signifies the presence of a single, benign, fluid-filled lesion within the bone structure of the left pelvic region. These cysts are typically asymptomatic and often discovered incidentally during imaging for other conditions. They are not cancerous and usually do not require aggressive treatment unless they cause pain or risk of fracture.

Apply this code when documentation clearly identifies a solitary bone cyst located specifically in the left pelvis. This diagnosis is typically supported by imaging reports (e.g., X-ray, MRI, CT scan) that describe the lesion's characteristics and location. Use this code for initial diagnosis, follow-up, or when the cyst is the primary reason for the encounter.

• Ensure the documentation specifies "solitary" to differentiate from multiple or other types of bone cysts.
• Verify the laterality (left) and anatomical site (pelvis) are explicitly stated in the diagnostic report.
• Do not use this code for aneurysmal bone cysts or other specified bone cysts, which have their own distinct codes.
