Lesion of medial popliteal nerve, unspecified lower limb
ICD-10 G57.40 is a billable code used to indicate a diagnosis of lesion of medial popliteal nerve, unspecified lower limb.
The medial popliteal nerve is a branch of the sciatic nerve that innervates the muscles and skin of the posterior aspect of the lower leg and foot. A lesion of this nerve can result from various causes, including trauma, compression, or systemic diseases such as diabetes. Clinically, patients may present with symptoms such as pain, weakness, or sensory loss in the affected lower limb. The diagnosis often involves a thorough clinical examination, nerve conduction studies, and imaging to assess for any underlying structural abnormalities. The unspecified nature of this code indicates that the specific cause or type of lesion has not been determined, which may complicate treatment and management strategies. Accurate coding is essential for appropriate reimbursement and to reflect the complexity of the patient's condition.
Detailed neurological examination findings, results of nerve conduction studies, and imaging reports.
Patients presenting with lower limb weakness, pain, or sensory changes following trauma or systemic illness.
Neurologists should document the specific nature of the lesion and any differential diagnoses considered.
Surgical notes, imaging studies, and pre-operative assessments.
Patients with knee injuries or surgeries that may impact the medial popliteal nerve.
Orthopedic surgeons should ensure that any nerve involvement is clearly documented in surgical reports.
Used to evaluate the function of the medial popliteal nerve in patients with suspected lesions.
Results of the nerve conduction study must be documented, including latencies and amplitudes.
Neurologists should ensure that the study is justified based on clinical findings.
Document the patient's symptoms, clinical findings, results of any diagnostic tests, and the rationale for using the unspecified code. Ensure that the documentation reflects the complexity of the patient's condition.
