Ganglion, left ankle and foot

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

This code is appropriate when documentation clearly identifies a ganglion cyst affecting the left ankle or foot. Supporting documentation should include the specific anatomical location and laterality (left).

• Ensure laterality is explicitly documented as "left" to avoid coding errors.
• Distinguish from other soft tissue masses; a definitive diagnosis of "ganglion" is required.
• Do not use for ganglions in other anatomical sites; specific codes exist for those locations.
