Ganglion, unspecified wrist

This diagnosis code signifies a ganglion cyst located on the wrist, where the specific side (left or right) is not documented. 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 a patient presents with a wrist ganglion, and the medical record does not specify whether it affects the left or right wrist. Documentation supporting its use would include a physician's note diagnosing a "wrist ganglion" without further laterality detail, or imaging reports confirming a ganglion at the wrist without specifying the side.

• Avoid using this code if laterality (left or right wrist) is documented; instead, choose the more specific code.
• Ensure the documentation clearly identifies the lesion as a ganglion, not another type of wrist mass.
• Consider querying the provider for laterality if it's missing and clinically relevant for treatment or follow-up.
