Lesion of lateral popliteal nerve, unspecified lower limb
ICD-10 G57.30 is a billable code used to indicate a diagnosis of lesion of lateral popliteal nerve, unspecified lower limb.
The lateral popliteal nerve, also known as the common peroneal nerve, is a branch of the sciatic nerve that innervates the muscles of the lower leg and foot. A lesion of this nerve can lead to a variety of symptoms, including weakness in foot dorsiflexion (foot drop), sensory loss over the lateral aspect of the leg and dorsum of the foot, and difficulty with ambulation. This condition can arise from various etiologies, including trauma, compression from external sources (such as a cast or prolonged pressure), or systemic diseases such as diabetes mellitus. Diagnosis typically involves a thorough clinical examination, nerve conduction studies, and electromyography to assess the extent of nerve damage and to rule out other neuropathies. Treatment may include physical therapy, orthotic devices, and in some cases, surgical intervention to relieve compression or repair the nerve. Accurate coding is essential for proper reimbursement and to reflect the complexity of the patient's condition.
Detailed neurological examination findings, results of nerve conduction studies, and treatment plans.
Patients presenting with foot drop, numbness, or tingling in the lower limb.
Ensure that all neurological deficits are documented and that the etiology of the lesion is clearly stated.
Surgical notes if applicable, imaging studies, and post-operative follow-up documentation.
Patients with trauma to the knee or leg leading to nerve injury.
Document any orthopedic interventions that may impact nerve recovery.
Used to evaluate the function of the lateral popliteal nerve in patients with suspected lesions.
Results of nerve conduction studies must be documented, including the specific nerves tested.
Neurologists should ensure that the rationale for testing is clearly documented.
Common symptoms include foot drop, weakness in dorsiflexion, and sensory loss over the lateral aspect of the leg and dorsum of the foot.
Diagnosis is typically made through clinical examination, nerve conduction studies, and electromyography to assess nerve function.
Treatment options may include physical therapy, orthotic devices, and surgical intervention if necessary.
