Other bursal cyst, unspecified hand

This code describes a fluid-filled sac, not otherwise specified, located within the bursae of an unspecified hand. It indicates the presence of a non-inflammatory, non-infectious cystic lesion that has developed in or around a bursa in the hand.

Use this code when documentation specifies a bursal cyst of the hand without further detail regarding its specific type (e.g., synovial, ganglion) or laterality. This code is appropriate when the physician's notes identify a "bursal cyst of the hand" or "cyst of hand bursa" without additional clarifying information.

• Avoid using this code if the documentation specifies a ganglion cyst or synovial cyst; use more specific codes from the M67 category.
• Query the provider for laterality (right or left hand) if not documented, as more specific codes exist.
• Ensure the documentation clearly states "bursal cyst" to differentiate from other types of hand cysts.
