95912 Nerve conduction studies; 11-12 studies

Name of the Procedure:

Nerve Conduction Studies (NCS); 11-12 studies

Summary

Nerve Conduction Studies (NCS) are diagnostic tests used to evaluate the function and health of the peripheral nerves. The procedure measures how quickly electrical signals move through your nerves.

Purpose

Nerve Conduction Studies are used to diagnose conditions that affect the nerves, such as carpal tunnel syndrome, peripheral neuropathy, and nerve damage from injuries. The goal is to identify abnormalities in nerve function to guide further treatment and management.

Indications

NCS is indicated for patients experiencing symptoms such as:

• Tingling, numbness, or a "pins and needles" sensation
• Muscle weakness or atrophy
• Unexplained pain in the limbs
• Radiating pain, especially from the neck or back The procedure is particularly warranted in cases where nerve damage or dysfunction is suspected based on symptoms and physical exam findings.

Preparation

• Patients may be asked to avoid lotions or oils on the skin before the test.
• Medications typically do not need to be adjusted, but patients should inform their healthcare provider of all medications they are currently taking.
• No fasting is required.

Procedure Description

1. The patient will be seated or lying down in a comfortable position.
2. The skin area over the nerves to be tested will be cleaned.
3. Small electrodes will be placed on the skin over specific nerves.
4. Mild electrical pulses will be sent through the electrodes to stimulate the nerves.
5. The speed and strength of the nerve signal is recorded.
6. Multiple sites may be tested to cover the 11-12 studies. Tools: Electrodes, Electric Stimulator, Recording Equipment Anesthesia: Generally not required; the procedure may cause brief discomfort.

Duration

The procedure typically takes about 45 minutes to 1 hour.

Setting

Nerve Conduction Studies are usually performed in a hospital, outpatient clinic, or specialized diagnostic center.

Personnel

The procedure is performed by a neurologist or trained technician, often under the supervision of a neurologist or physiatrist.

Risks and Complications

Risks:

• Mild discomfort during electrical stimulation
• Rarely, slight bruising or swelling at electrode sites Complications: Generally, the procedure is very safe with minimal risk of serious complications.

Benefits

Benefits include the accurate identification of nerve-related problems, which can lead to appropriate and timely treatment. Results are often available quickly and help in diagnosing the underlying causes of symptoms.

Recovery

Post-procedure:

• Typically, no special care is required.
• Patients can resume normal activities immediately after the test.
• There may be minor soreness or tingling, which resolves quickly.

Alternatives

Alternative diagnostic tests include Electromyography (EMG) for further evaluation of muscle function and health. Imaging tests like MRI or ultrasounds may also be used, though they do not measure nerve function directly.

Patient Experience

Patients may experience mild and brief discomfort from the electrical pulses delivered during the test. The procedure is generally well-tolerated, and any discomfort ceases as soon as the test is concluded. No significant pain management is typically needed, and patients can resume daily activities immediately afterward.
