Ganglion, left hand

This code signifies the presence of a ganglion cyst located on the left hand. A ganglion is a non-cancerous, fluid-filled sac that typically forms on joints or tendons, often appearing as a lump under the skin. In this specific instance, the cyst is situated on the patient's left hand.

Use this code when documentation clearly indicates a diagnosis of a ganglion cyst affecting the left hand. This applies to both new diagnoses and follow-up encounters for an existing ganglion on the left hand. Supporting documentation would include physician notes detailing the location and diagnosis of the ganglion.

• Ensure the laterality is accurately documented as "left hand" to avoid miscoding.
• Distinguish from other soft tissue masses or tumors of the hand; this code is specific to a ganglion.
• Do not use for ganglions located on the wrist or other parts of the upper extremity; specific codes exist for those locations.
