Flail joint, left wrist

This code signifies a flail joint affecting the left wrist. A flail joint is characterized by abnormal, excessive, and uncontrolled mobility due to severe ligamentous laxity or destruction, often resulting from trauma or neurological impairment. This instability compromises the joint's function and stability.

This code is appropriate when documentation clearly indicates a diagnosis of a flail joint specifically located in the left wrist. It should be used when the physician's assessment describes significant instability and hypermobility of the wrist joint, consistent with a flail presentation. Supporting documentation would include physical exam findings detailing excessive range of motion and lack of structural integrity.

• Ensure documentation specifies "flail joint" and not just general instability or hypermobility, as these are distinct conditions.
• Verify the laterality is explicitly stated as "left wrist" to avoid incorrect coding.
• Consider any underlying cause (e.g., trauma, neurological condition) and code it as a primary or secondary diagnosis as appropriate, following ICD-10-CM sequencing guidelines.
