ICD 10 CM G57.31 | Description & Clinical Information
ICD 10 G57.31 describes a specific medical condition characterized by the impairment or damage of the lateral popliteal nerve located in the right lower limb, which results in a weakened ability to dorsiflex (upward bending) and evert (turning outward) the foot, typically occurring at or near the knee.
Official Description Of G57.31
The ICD 10 CM book defines ICD 10 code G57.31 as:
Excludes1: current traumatic nerve disorder – see nerve injury by body region
When To Use G57.31
The diagnosis describes by the ICD 10 CM G57.31 code is a medical condition that affects the lateral popliteal nerve, also referred to as the common peroneal nerve or the superficial fibular nerve. This nerve is a smaller branch of the sciatic nerve that is responsible for supplying the skin and various muscles in the back of the thigh as well as the anterior and lateral parts of the leg and foot.
One of the most common causes of this condition is injury to the neck of the fibula, where the lateral popliteal nerve is particularly vulnerable due to its limited protection from skin and fascia. Other factors that may lead to the development of lateral popliteal nerve lesions include diabetes and other underlying medical conditions.
Depending on the extent and location of the lesion, patients with this condition may experience a range of symptoms such as wasting of peronei and tibialis anterior muscles located along the lateral aspect of the leg, weakness in dorsiflexion and eversion of the foot, foot drop or difficulty lifting the foot, and an abnormal high-stepping gait.
Providers typically diagnose the lateral popliteal nerve lesion by taking a detailed medical history, conducting a thorough physical examination, and identifying specific signs and symptoms that are associated with the condition. Additional diagnostic tests such as X-rays, MRI, ultrasound, EMG, and NCV of the lower extremities may also be performed to confirm the diagnosis.
The mainstay of treatment for this condition includes a combination of anti-inflammatory medications, NSAIDs, steroid injections, exercises, physical therapy, and devices such as braces and splints. These therapies aim to alleviate symptoms, reduce inflammation, and strengthen the affected muscles.
However, in certain cases, surgical intervention may be required to release any pressure or compression that is being exerted on the nerve. This may be necessary if conservative treatments have not been successful in managing symptoms or if the damage to the nerve is significant.
In conclusion, the ICD 10 CM G57.31 diagnosis code relates to the lateral popliteal nerve lesion, a condition that can cause a range of symptoms and discomfort. Timely diagnosis and appropriate management can help alleviate symptoms and prevent the progression of the condition. It is important for healthcare providers to remain up to date on the latest treatment options and guidelines for lateral popliteal nerve lesions to ensure the best outcomes for their patients.
