Lesion of lateral popliteal nerve, right lower limb
ICD-10 G57.31 is a billable code used to indicate a diagnosis of lesion of lateral popliteal nerve, right 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 result from various causes, including trauma, compression, or entrapment, leading to motor and sensory deficits in the right lower limb. Clinically, patients may present with foot drop, weakness in ankle dorsiflexion, and sensory loss over the dorsum of the foot and lateral aspect of the leg. The condition can arise from prolonged pressure on the nerve, such as from crossing the legs, or from external compression due to tumors or swelling. Diagnosis typically involves a thorough clinical examination, nerve conduction studies, and possibly imaging studies to identify the underlying cause of the nerve lesion. 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, including motor and sensory assessments.
Patients presenting with foot drop, numbness, or weakness in the lower limb.
Ensure that nerve conduction studies are documented and interpreted correctly.
Surgical notes if intervention is performed, imaging results, and pre-operative assessments.
Patients with traumatic injuries leading to nerve lesions or those requiring surgical decompression.
Document any orthopedic interventions that may impact nerve function.
Used to confirm the diagnosis of lateral popliteal nerve lesion.
Results of nerve conduction studies must be documented in the patient's medical record.
Neurologists should ensure that the studies are interpreted correctly and correlate with clinical findings.
Common causes include trauma, compression from prolonged sitting or crossing legs, and conditions such as diabetes that may lead to neuropathy.
