How To Use CPT Code 92516

CPT 92516 describes the evaluation of facial nerve function and integrity using electroneuronography (ENoG). This article will cover the description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information, similar codes and billing examples.

1. What is CPT Code 92516?

CPT 92516 can be used to describe the evaluation of facial nerve function and integrity using electroneuronography (ENoG). This noninvasive test involves the use of electrical stimulation to assess the facial nerve when a patient has facial nerve impairment. The test compares the nerve response on the normal side of the face to the abnormal side, helping to determine if surgery is necessary.

2. Official Description

The official description of CPT code 92516 is: ‘Facial nerve function studies (eg, electroneuronography).’ This code is used when the provider uses electroneuronography, a noninvasive test that uses electrical stimulation, to evaluate facial nerve function and integrity in patients with facial nerve impairment.

3. Procedure

  1. The provider prepares the patient by cleaning their skin for the application of stimulus and recording electrodes.
  2. Small cup stimulus electrodes are placed at or near the base of the ear, and response electrodes are placed at or near the skin folds along each side of the nose to the corners of the mouth.
  3. The provider performs electrical stimulation on the facial nerve and records the resulting response.
  4. The stimulation is repeated, with the electrodes placed in different locations in the same area, to obtain the greatest response possible.
  5. The study is conducted first on the normal side of the face, followed by the impaired side.
  6. A computer records and interprets the responses, helping to diagnose facial nerve disorders such as Bell’s palsy.

4. Qualifying circumstances

CPT 92516 is used for patients with facial nerve impairment who require evaluation of facial nerve function and integrity. This test helps diagnose conditions such as Bell’s palsy, which causes facial paralysis on the affected side. The facial nerve is responsible for controlling facial expression muscles and providing sensory input for taste.

5. When to use CPT code 92516

CPT code 92516 should be used when a provider performs electroneuronography to evaluate facial nerve function and integrity in patients with facial nerve impairment. This code is not appropriate for monitoring during radiologic guidance procedures.

6. Documentation requirements

To support a claim for CPT 92516, the provider must document the following information:

  • Patient’s diagnosis and indication for the test
  • Details of the electroneuronography procedure, including electrode placement and stimulation parameters
  • Results of the test, comparing the normal and impaired sides
  • Interpretation of the test findings
  • Signature of the provider performing the test

7. Billing guidelines

When billing for CPT 92516, ensure that the test is performed to evaluate facial nerve function and integrity using electroneuronography. This code should not be reported for monitoring during radiologic guidance procedures. It is important to follow the specific documentation requirements and guidelines provided by the payer to ensure accurate and appropriate billing.

8. Historical information

CPT 92516 was added to the Current Procedural Terminology system on January 1, 1990. There have been no updates to the code since its addition.

9. Examples

  1. A patient with facial nerve impairment undergoes electroneuronography to evaluate the function and integrity of their facial nerve.
  2. A provider performs electroneuronography on a patient with Bell’s palsy to assess the response of the facial nerve on the impaired side compared to the normal side.
  3. An individual with facial nerve impairment undergoes electroneuronography to determine if surgery is necessary for their condition.
  4. A provider uses electroneuronography to evaluate the facial nerve function and integrity of a patient with facial paralysis.
  5. A patient with facial nerve impairment undergoes electroneuronography to aid in the diagnosis of their condition.
  6. A provider performs electroneuronography on a patient with facial nerve impairment to assess the effectiveness of their current treatment.
  7. An individual with facial nerve impairment undergoes electroneuronography to monitor the progress of their condition over time.
  8. A provider uses electroneuronography to evaluate the facial nerve function and integrity of a patient with facial muscle weakness.
  9. A patient with facial nerve impairment undergoes electroneuronography to determine the extent of their facial nerve damage.
  10. A provider performs electroneuronography on a patient with facial nerve impairment to guide the development of a treatment plan.
