Lesion of ulnar nerve, left upper limb
ICD-10 G56.22 is a billable code used to indicate a diagnosis of lesion of ulnar nerve, left upper limb.
The ulnar nerve is one of the major nerves of the upper limb, primarily responsible for the sensory and motor functions of the hand. A lesion of the ulnar nerve can occur due to various factors, including trauma, compression, or systemic diseases. Clinically, patients may present with symptoms such as numbness, tingling, or weakness in the ring and little fingers, often referred to as 'ulnar nerve palsy.' The condition can arise from entrapment at the elbow (cubital tunnel syndrome) or wrist (Guyon's canal syndrome). Diagnosis typically involves a thorough clinical examination, nerve conduction studies, and electromyography to assess the extent of nerve damage and function. Treatment options may include conservative management, such as splinting and physical therapy, or surgical intervention in severe cases. Accurate coding is essential for proper reimbursement and tracking of healthcare outcomes.
Detailed neurological examination findings, including sensory and motor assessments.
Patients presenting with numbness or weakness in the hand, particularly after trauma or repetitive use.
Ensure documentation includes the duration of symptoms and any prior treatments attempted.
Surgical notes if applicable, imaging studies, and pre-operative assessments.
Patients requiring surgical intervention for ulnar nerve decompression.
Document the surgical approach and any intraoperative findings that may affect coding.
Used when surgical intervention is required for ulnar nerve entrapment.
Surgical notes detailing the procedure and findings.
Orthopedic surgeons should document the surgical approach and any complications.
Common symptoms include numbness and tingling in the ring and little fingers, weakness in hand grip, and pain in the elbow or wrist area.
