Wrist drop, right wrist

This code signifies a condition characterized by the inability to extend the right wrist and fingers, resulting in a drooping or "dropped" appearance of the hand. It typically indicates a radial nerve palsy affecting the extensor muscles of the wrist and hand.

Apply this code when documentation explicitly states "wrist drop" affecting the right wrist, often due to radial nerve injury, compression, or neuropathy. Supporting documentation should include physical exam findings noting the inability to dorsiflex the right wrist and/or fingers.

• Ensure laterality is clearly documented as "right wrist" to avoid incorrect coding.
• Do not confuse with other wrist deformities or contractures that do not specifically involve radial nerve palsy.
• Always look for an underlying cause (e.g., fracture, nerve compression) and code it as a primary diagnosis if applicable, with this code as a secondary diagnosis.
