Lesion of ulnar nerve, unspecified upper limb
ICD-10 G56.20 is a billable code used to indicate a diagnosis of lesion of ulnar nerve, unspecified upper limb.
The ulnar nerve is one of the major nerves of the upper limb, primarily responsible for the sensation and motor function of the forearm and hand. A lesion of the ulnar nerve can occur due to various factors, including trauma, compression, or systemic diseases. Symptoms may include numbness, tingling, or weakness in the hand, particularly affecting the ring and little fingers. The condition can arise from repetitive stress, direct injury, or conditions such as cubital tunnel syndrome, where the nerve is compressed at the elbow. Diagnosis typically involves a thorough clinical examination, patient history, and may include nerve conduction studies to assess the function of the ulnar nerve. Treatment options vary based on the severity and cause of the lesion, ranging from conservative management, such as splinting and physical therapy, to surgical intervention in more severe cases. Accurate coding is essential for proper reimbursement and to reflect the patient's condition in medical records.
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 that nerve conduction studies are documented and interpreted correctly to support the diagnosis.
Surgical notes if intervention is performed, including pre-operative assessments.
Patients with ulnar nerve entrapment requiring surgical release.
Document any anatomical variations or previous surgeries that may affect the ulnar nerve.
Used to evaluate the function of the ulnar nerve in patients with suspected lesions.
Document the results of the nerve conduction study and the rationale for testing.
Neurologists should ensure that the study is performed according to established protocols.
Common causes include trauma, repetitive stress injuries, and conditions like diabetes that can lead to neuropathy.
Ulnar nerve lesions typically present with symptoms affecting the ring and little fingers, while other neuropathies may have different patterns of sensory and motor involvement.
