Sciatica
1746873896
Sciatica is pain caused by irritation or pressure on the sciatic nerve, the longest nerve in the body. It starts in the lower back, runs through the hips and buttocks, and travels down the legs. This can lead to sharp pain, tingling, numbness, or weakness, usually affecting one leg.
To diagnose sciatica, a provider will begin with a physical exam to check for pain, reflex changes, or weakness. One common test is the Straight Leg Raise, where lifting the leg while lying down may trigger shooting pain. If needed, imaging tests like an X-ray, MRI, or CT scan can help identify herniated discs, bone spurs, or nerve compression. In some cases, an EMG (electromyography) may be used to test nerve function.
Sciatica is often caused by herniated discs pressing on the nerve, bone spurs or overgrowths in the spine, or spinal narrowing, also known as stenosis. It most commonly affects the lower back, or lumbar spine, at two key locations. When it occurs at L4-L5, pain, numbness, or weakness can spread to the top of the foot or big toe. When it happens at L5-S1, pain often travels down the back of the leg to the heel or outer foot.
Most cases improve without surgery. Physical therapy and specific exercises can help relieve pressure on the nerve. Medications, such as anti-inflammatories, can reduce pain, and in more severe cases, injections may provide longer-lasting relief. Surgery is rare and is only considered if symptoms don’t improve or if the nerve is severely pinched.

FAQs
Can sciatica be prevented?
While not all cases of sciatica can be prevented, maintaining good posture, engaging in regular exercise that strengthens the core and lower back, and using proper lifting techniques can reduce the risk. Managing weight and avoiding prolonged sitting can also help prevent sciatica.
How is sciatica diagnosed?
Sciatica is diagnosed through a physical exam that may include specific tests such as the Straight Leg Raise test to identify pain. Imaging tests like X-rays, MRIs, or CT scans can help pinpoint herniated discs or bone spurs. An EMG may be performed to test nerve function if needed.
What are the treatment options for sciatica?
Treatment options for sciatica primarily focus on non-surgical approaches such as physical therapy and exercises to relieve nerve pressure. Medications like anti-inflammatories can help reduce pain, and in severe cases, injections may offer longer-lasting relief. Surgery is considered only when symptoms do not improve or if the nerve is severely pinched.
What causes sciatica and how does it affect the body?
Sciatica is caused by irritation or pressure on the sciatic nerve, often resulting from herniated discs, bone spurs, or spinal stenosis. It affects the body by causing sharp pain, tingling, numbness, or weakness that starts in the lower back and travels down the legs, usually affecting one side of the body.
What is the ICD-10 code for sciatica and why is it important?
The ICD-10 code for sciatica is M54.3. This coding is important for accurate diagnosis documentation, reimbursement processes, and effective treatment planning. The code can be further specified by side, such as M54.30 for unspecified side, M54.31 for the right side, and M54.32 for the left side.
