Ganglion, left shoulder

This code signifies the presence of a ganglion cyst located specifically on the left shoulder. A ganglion is a non-cancerous, fluid-filled sac that typically forms on joints or tendons, often presenting as a palpable lump.

Use this code when documentation clearly indicates a diagnosis of a ganglion cyst affecting the left shoulder joint or surrounding tendons. This diagnosis is typically made through physical examination and may be confirmed by imaging studies such as ultrasound or MRI.

• Ensure laterality is explicitly documented for the shoulder (left vs. right).
• Do not confuse with other soft tissue masses or tumors; confirm the diagnosis is specifically a ganglion.
• Consider additional codes for associated symptoms (e.g., pain, restricted movement) if documented.
