Official Description

Physiologic recording of tremor using accelerometer(s) and/or gyroscope(s) (including frequency and amplitude), including interpretation and report

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 0199T refers to the physiologic recording of tremor utilizing advanced technology such as accelerometers and gyroscopes. This procedure is specifically designed to measure the frequency and amplitude of tremors, which are involuntary muscle movements that can significantly impact a patient's quality of life. The most prevalent type of tremor assessed through this method is essential tremor, characterized by rhythmic, oscillatory movements primarily affecting the hands, although it can also involve other body parts such as the head, voice, tongue, legs, and trunk. During the procedure, a device equipped with these sensors is affixed to the patient's arm, wrist, or finger, allowing for precise measurement of tremor characteristics. The patient is typically instructed to perform a series of tasks, including resting their hands and raising their arms to touch their nose, which helps in capturing the tremor data accurately. The device communicates wirelessly with a computer system, enabling real-time data collection. Patients may wear the device for an extended duration, during which they can maintain a diary to log medication intake and instances of severe tremors. The collected data is subsequently analyzed by a physician, who interprets the results and generates a comprehensive report detailing the findings.

1. Indications

The physiologic recording of tremor using accelerometer(s) and/or gyroscope(s) is indicated for the assessment of various tremor types, particularly in patients exhibiting symptoms of essential tremor. This procedure is performed to evaluate the severity and characteristics of tremors that may affect the patient's daily functioning and quality of life. The following conditions may warrant this procedure:

  • Essential Tremor A common movement disorder characterized by involuntary, rhythmic shaking, primarily affecting the hands and arms.
  • Parkinsonian Tremor Tremors associated with Parkinson's disease, which may present differently than essential tremor.
  • Other Movement Disorders Conditions that may involve tremors, necessitating detailed assessment for appropriate management.

2. Procedure

The procedure for physiologic recording of tremor involves several key steps to ensure accurate measurement and analysis of the tremor characteristics. The following procedural steps are undertaken:

  • Step 1: Device Placement The first step involves placing the accelerometer and/or gyroscope device on the patient's arm, wrist, or finger. This positioning is crucial for capturing the tremor data effectively, as it allows the sensors to detect the movements accurately.
  • Step 2: Patient Instructions Once the device is securely attached, the patient is instructed to perform specific tasks. Initially, the patient is asked to rest their hands in their lap for several seconds, which helps establish a baseline measurement of tremor activity.
  • Step 3: Active Movement Following the resting phase, the patient raises their arms straight out in front of their body and is then instructed to touch their nose. This active movement is essential for evaluating the tremor's frequency and amplitude during functional tasks.
  • Step 4: Data Collection The device is programmed to wirelessly communicate with a computer unit, which records the tremor data in real-time. This technology allows for continuous monitoring and evaluation of the tremor characteristics throughout the procedure.
  • Step 5: Extended Monitoring The patient may wear the device for an extended period, during which they can maintain a diary to document medication intake and instances of severe tremors. This additional data collection aids in a comprehensive assessment of the tremor's impact on the patient's daily life.
  • Step 6: Data Interpretation After the data collection phase, the recorded information is analyzed and interpreted by a physician. The physician evaluates the frequency and amplitude of the tremor, leading to a detailed understanding of the patient's condition.
  • Step 7: Report Generation Finally, a written report is generated, summarizing the findings from the physiologic recording. This report serves as a critical tool for guiding further management and treatment decisions for the patient.

3. Post-Procedure

Post-procedure care involves reviewing the findings from the physiologic recording with the patient. The physician will discuss the results outlined in the report, including the frequency and amplitude of the tremor, and how these findings relate to the patient's symptoms and overall condition. Depending on the results, further diagnostic evaluations or treatment options may be recommended. Patients may also be advised on how to manage their symptoms and the importance of adhering to any prescribed medication regimens. Continuous monitoring and follow-up appointments may be necessary to assess the effectiveness of any interventions implemented based on the findings from the procedure.
