Ganglion, left wrist

This code describes a ganglion cyst located on the left wrist. A ganglion is a non-cancerous, fluid-filled sac that typically forms on joints or tendons, often appearing as a palpable lump. It arises from the synovial lining of a joint or tendon sheath.

Use this code when documentation clearly identifies a ganglion cyst specifically affecting the left wrist. This diagnosis is typically supported by physical examination findings, patient history of a palpable mass, and sometimes imaging studies like ultrasound or MRI to confirm the cystic nature and location.

• Ensure laterality is precisely documented; distinguish between left, right, and bilateral wrist involvement.
• Do not confuse with other wrist masses such as lipomas or fibromas; the documentation must specify "ganglion."
• Consider an additional code for any associated symptoms, such as pain (e.g., G89.11 for acute pain, G89.21 for chronic pain), if documented and clinically significant.
