Other bursal cyst, unspecified wrist

This code describes a fluid-filled sac, distinct from a ganglion cyst, that has formed within or adjacent to a bursa in the wrist region. It indicates a non-inflammatory, benign swelling resulting from synovial fluid accumulation. The specific wrist (left or right) is not documented or is unknown.

Use this code when documentation specifies a "bursal cyst" of the wrist without further detail on laterality or when the laterality is explicitly stated as unspecified. This diagnosis is typically made based on physical examination and imaging studies such as ultrasound or MRI.

• Do not use this code if the documentation specifies a ganglion cyst; refer to codes in the G50-G51 range.
• Always strive for laterality (right or left wrist) if documented, using more specific codes like M71.331 or M71.332.
• Ensure the documentation clearly distinguishes a bursal cyst from other wrist masses or inflammatory conditions.
