Carpal tunnel syndrome, bilateral upper limbs

This diagnosis code signifies the presence of carpal tunnel syndrome affecting both the right and left upper limbs. It describes a condition where the median nerve is compressed at the wrist, leading to symptoms such as pain, numbness, tingling, and weakness in the hand and fingers.

This code is appropriate when a patient presents with documented carpal tunnel syndrome affecting both wrists. Clinical documentation should clearly indicate bilateral involvement, often supported by physical examination findings, nerve conduction studies, or electromyography confirming median nerve compression in both upper extremities.

• Ensure documentation explicitly states "bilateral" or specifies involvement of both the right and left upper limbs.
• Do not use this code if only one limb is affected; instead, use the appropriate unilateral code (G56.01 for right, G56.02 for left).
• Consider sequencing this code after any underlying systemic conditions contributing to carpal tunnel syndrome, if applicable.
