Flail joint, right hand

This code signifies a flail joint affecting the right hand. A flail joint is characterized by extreme laxity and instability, resulting in a loss of normal joint function and control, often due to severe ligamentous injury or nerve damage leading to muscle paralysis.

Assign this code when documentation clearly indicates a diagnosis of a flail joint specifically located in the patient's right hand. This typically occurs following significant trauma, neurological conditions, or severe degenerative processes that compromise joint integrity and stability.

• Ensure documentation specifies "flail joint" and laterality (right hand) to support this code.
• Do not confuse with general joint instability or hypermobility; "flail" implies a more severe, uncontrolled state.
• Consider sequencing this code with an underlying cause if known and documented (e.g., nerve injury, severe fracture nonunion).
