Lesion of medial popliteal nerve, right lower limb
ICD-10 G57.41 is a billable code used to indicate a diagnosis of lesion of medial popliteal nerve, right lower limb.
The medial popliteal nerve, a branch of the sciatic nerve, is responsible for innervating the muscles and skin in the posterior compartment of the leg and the plantar aspect of the foot. A lesion of this nerve can result from various etiologies, including trauma, compression, or systemic diseases such as diabetes mellitus. Clinically, patients may present with symptoms such as pain, weakness, or sensory loss in the right lower limb, particularly affecting the calf and foot. The diagnosis is often confirmed through clinical examination and may be supported by nerve conduction studies (NCS) that assess the electrical activity of the nerve. These studies can help differentiate between neuropathies and other conditions that may mimic the symptoms of a medial popliteal nerve lesion. Treatment options vary based on the underlying cause and may include physical therapy, pain management, or surgical intervention in cases of significant compression or injury.
Detailed neurological examination findings, including sensory and motor assessments.
Patients presenting with unilateral leg weakness or sensory loss.
Ensure that all relevant diagnostic tests, such as NCS, are documented to support the diagnosis.
Surgical notes if intervention is performed, including pre-operative and post-operative assessments.
Patients with traumatic injuries leading to nerve lesions.
Document the mechanism of injury and any associated orthopedic conditions.
Used to confirm the diagnosis of a medial popliteal nerve lesion.
Document the findings of the nerve conduction study and correlate with clinical symptoms.
Neurologists should ensure that the study is performed and interpreted correctly.
Common causes include trauma, compression from tumors or cysts, and systemic conditions such as diabetes that can lead to neuropathy.
