CPT 92544 describes the optokinetic nystagmus test, which assesses the bidirectional movement of the eyes with foveal or peripheral stimulation and records the results. This article will cover the description, official details, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information, similar codes and billing examples.
1. What is CPT Code 92544?
CPT 92544 can be used to describe the optokinetic nystagmus test, a procedure that evaluates the bidirectional movement of the eyes with foveal or peripheral stimulation. This test helps assess the patient’s eye reflexes and visual acuity. It involves using a drum covered with light and dark vertical stripes, which is rotated in different directions while the patient focuses on it. The eye movements are observed and recorded to determine any irregularities or involuntary movements, indicating nystagmus.
2. Official Description
The official description of CPT code 92544 is: ‘Optokinetic nystagmus test, bidirectional, foveal or peripheral stimulation, with recording.’
- The patient is positioned in front of a drum covered with light and dark vertical stripes.
- The patient is instructed to keep their head straight and fixed while staring at the drum.
- The drum is slowly rotated in one direction, and then in the opposite direction.
- The healthcare professional observes the patient’s eye movements and records any irregularities or involuntary movements.
- The extent of the patient’s visual acuity can be estimated by analyzing the eye movements recorded by electrodes attached to the patient’s body.
4. Qualifying circumstances
CPT 92544 is typically performed on patients who exhibit symptoms or signs of nystagmus, a regular, repetitive, and involuntary rhythmic ocular movement of the eyes. The test helps diagnose and evaluate the severity of nystagmus. It should not be reported in conjunction with CPT codes 92270, 92540, or the set of 92541, 92542, and 92545.
5. When to use CPT code 92544
CPT code 92544 should be used when conducting the optokinetic nystagmus test with bidirectional stimulation and recording the results. It is appropriate for patients who require evaluation of their eye reflexes and visual acuity, particularly those suspected of having nystagmus. This code should not be used in conjunction with certain other codes, as mentioned in the qualifying circumstances section.
6. Documentation requirements
To support a claim for CPT 92544, the healthcare professional must document the following information:
- Patient’s symptoms or signs indicating the need for the optokinetic nystagmus test
- Details of the test procedure, including the use of bidirectional stimulation and recording
- Date and duration of the test
- Results of the test, including any irregular or involuntary eye movements observed
- Signature of the healthcare professional performing the test
7. Billing guidelines
When billing for CPT 92544, ensure that the test is performed according to the official description and qualifying circumstances. It should not be reported in conjunction with certain other codes, as mentioned earlier. Additional tips for accurate billing include considering the location of the testing, as it may affect coding for vestibular function tests with recording.
8. Historical information
CPT 92544 was added to the Current Procedural Terminology system on January 1, 1990. There have been no updates or changes to the code since its addition.
- A patient with suspected nystagmus undergoes the optokinetic nystagmus test to assess their eye reflexes and visual acuity.
- A healthcare professional performs the optokinetic nystagmus test on a patient with a history of irregular eye movements to determine the severity of their nystagmus.
- A child with developmental delays undergoes the optokinetic nystagmus test to evaluate their eye movements and potential visual impairments.
- A patient with vertigo and balance issues undergoes the optokinetic nystagmus test to assess their vestibular function and identify any abnormalities.
- A healthcare professional uses the optokinetic nystagmus test to monitor the progress of a patient with a known nystagmus condition and adjust their treatment plan accordingly.
- A patient with a recent head injury undergoes the optokinetic nystagmus test to evaluate their eye reflexes and detect any potential neurological damage.
- A healthcare professional performs the optokinetic nystagmus test as part of a comprehensive assessment for a patient with suspected vestibular disorders.
- A child with congenital nystagmus undergoes the optokinetic nystagmus test to determine the severity and characteristics of their eye movements.
- A patient with a history of motion sickness undergoes the optokinetic nystagmus test to assess their susceptibility to nystagmus and potential visual disturbances.
- A healthcare professional uses the optokinetic nystagmus test to evaluate the effectiveness of a patient’s ongoing treatment for their nystagmus condition.
