Ganglion, right hand

This code identifies a ganglion cyst located specifically on the right hand. A ganglion is a non-cancerous, fluid-filled sac that typically forms on tendons or joints, often appearing as a palpable lump. In this instance, it refers to such a cyst affecting any part of the right hand.

Apply this code when documentation clearly indicates the presence of a ganglion cyst on the patient's right hand. This diagnosis is typically supported by physical examination findings, patient history of a palpable mass, and sometimes imaging studies like ultrasound or MRI confirming the cystic nature and location.

• Ensure laterality is explicitly documented as "right hand" to support this specific code.
• Do not use this code for ganglia located on the wrist; separate codes exist for wrist involvement.
• If the specific location on the hand (e.g., finger, palm) is documented, consider if a more specific subcategory is available, though M67.441 is appropriate for general right hand involvement.
