CPT® Code 0615T

Automated analysis of binocular eye movements without spatial calibration, including disconjugacy, saccades, and pupillary dynamics for the assessment of concussion, with interpretation and report

The CPT® Code 0615T refers to an automated analysis of binocular eye movements that does not require spatial calibration. This procedure is specifically designed for the assessment of concussion, a condition that can significantly affect ocular motility. The analysis includes the evaluation of disconjugacy, saccades, and pupillary dynamics, which are critical components in understanding how well the eyes function following a suspected mild traumatic brain injury (mTBI). Unlike traditional imaging techniques that may not reveal subtle changes in brain function, this noninvasive test provides valuable insights into the patient's neurological status by tracking eye movements. The methodology involves the patient resting their chin and forehead in a monitor viewer while observing a video that moves around the screen's perimeter. This setup allows for the continuous tracking of the pupils over a period of 220 seconds. The data collected is then compared to a control database to assess the severity of any abnormal eye movements. The non-spatially calibrated nature of this analysis is particularly advantageous, as it mitigates the risk of misinterpretation that can occur with spatial calibration, where one eye's limited movement might be inaccurately recorded as normal. Overall, this procedure serves as a crucial tool in the timely assessment and diagnosis of concussion-related impairments in eye movement.
