How To Use CPT Code 95929

CPT 95929 describes the procedure for a central motor evoked potential study using transcranial motor stimulation to evaluate the motor pathways supplying the lower limbs. This article will cover the official description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information, similar codes and billing examples.

1. What is CPT Code 95929?

CPT 95929 can be used to describe a central motor evoked potential study performed by a healthcare provider. This study involves transcranial motor stimulation, where mild electric current is applied to the scalp to stimulate the motor cortex. The goal of this procedure is to evaluate the motor pathways that supply the lower limb muscles.

2. Official Description

The official description of CPT code 95929 is: ‘Central motor evoked potential study (transcranial motor stimulation); lower limbs.’

3. Procedure

1. The healthcare provider performs a central motor evoked potential study by applying mild electric current to the scalp to stimulate the motor cortex.
2. This stimulation generates motor responses in the muscles of the legs or feet.
3. The provider records these motor potentials using electrodes placed over the spinal cord or in distal muscle groups.
4. The recorded motor potentials are processed by a computer and converted into waveforms.
5. The provider analyzes these waveforms to evaluate the motor pathways supplying the lower limbs.

4. Qualifying circumstances

CPT 95929 is typically performed during orthopedic surgery to ensure that motor pathways in the central nervous system are intact. The procedure is used to evaluate the motor pathways supplying the lower limbs. It is important to note that CPT code 95929 should not be reported in conjunction with CPT code 95928.

5. When to use CPT code 95929

CPT code 95929 should be used when a healthcare provider performs a central motor evoked potential study using transcranial motor stimulation to evaluate the motor pathways supplying the lower limbs. It is important to follow the guidelines and not report CPT code 95929 in conjunction with CPT code 95928.

6. Documentation requirements

To support a claim for CPT code 95929, the healthcare provider must document the following information:

• Reason for performing the central motor evoked potential study
• Details of the procedure, including the use of transcranial motor stimulation
• Recorded motor potentials and waveforms
• Analysis of the waveforms and evaluation of the motor pathways supplying the lower limbs

7. Billing guidelines

When billing for CPT code 95929, ensure that the procedure is performed by a qualified healthcare provider. It is important to follow the guidelines and not report CPT code 95929 in conjunction with CPT code 95928. If reporting only the professional or technical component, appropriate modifiers should be appended to the code.

8. Historical information

CPT code 95929 was added to the Current Procedural Terminology system on January 1, 2005. There have been no updates to the code since its addition.

9. Examples

1. A healthcare provider performs a central motor evoked potential study using transcranial motor stimulation to evaluate the motor pathways supplying the lower limbs of a patient undergoing orthopedic surgery.
2. During a surgical procedure, a provider uses transcranial motor stimulation to assess the motor pathways supplying the lower limbs of a patient with a suspected neurological condition.
3. A healthcare provider performs a central motor evoked potential study on a patient with a spinal cord injury to evaluate the integrity of the motor pathways supplying the lower limbs.
4. As part of a research study, a provider conducts a central motor evoked potential study using transcranial motor stimulation to investigate the motor pathways supplying the lower limbs in healthy individuals.
5. During a preoperative assessment, a provider performs a central motor evoked potential study to evaluate the motor pathways supplying the lower limbs of a patient scheduled for orthopedic surgery.
6. A healthcare provider uses transcranial motor stimulation to assess the motor pathways supplying the lower limbs of a patient with suspected nerve damage.
7. During a rehabilitation session, a provider performs a central motor evoked potential study to evaluate the motor pathways supplying the lower limbs of a patient recovering from a stroke.
8. A healthcare provider conducts a central motor evoked potential study using transcranial motor stimulation to assess the motor pathways supplying the lower limbs of a patient with a spinal cord tumor.
9. As part of a diagnostic workup, a provider performs a central motor evoked potential study to evaluate the motor pathways supplying the lower limbs of a patient with unexplained muscle weakness.
10. A healthcare provider uses transcranial motor stimulation to assess the motor pathways supplying the lower limbs of a patient with suspected nerve compression.
