Official Description

Comprehensive computer-based motion analysis by video-taping and 3D kinematics; with dynamic plantar pressure measurements during walking

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Comprehensive computer-based motion analysis, as described by CPT® Code 96001, involves a detailed assessment of a patient's movement patterns through advanced technology. This procedure is particularly beneficial for individuals with complex movement disorders, such as those resulting from cerebral palsy, spina bifida, traumatic brain injury, amputation, stroke, or other conditions that impair mobility. The analysis is conducted in a specialized motion analysis laboratory equipped with sophisticated tools, including video recording from multiple angles, three-dimensional (3D) kinematic assessments, and dynamic electromyography. The primary goal of this comprehensive analysis is to evaluate the patient's movement in order to inform decisions regarding therapeutic interventions, which may include the selection of appropriate braces or prosthetics, as well as potential surgical options. The procedure not only captures joint movements and power during walking but also incorporates dynamic plantar pressure measurements, which provide critical insights into weight-bearing pressures on the feet. This multifaceted approach ensures a thorough understanding of the patient's movement capabilities and challenges, ultimately guiding the development of tailored treatment plans.

1. Indications

The comprehensive computer-based motion analysis performed under CPT® Code 96001 is indicated for patients exhibiting complex movement problems. These conditions may include:

  • Cerebral Palsy A neurological disorder that affects movement and muscle tone, often leading to difficulties in coordination and control.
  • Spina Bifida A birth defect that occurs when the spine does not close completely, potentially resulting in mobility issues.
  • Traumatic Brain Injury An injury to the brain that can affect various functions, including movement and coordination.
  • Amputation The loss of a limb, which can significantly impact mobility and require assessment for prosthetic fitting.
  • Stroke A medical condition that can lead to sudden loss of movement or coordination due to disrupted blood flow to the brain.
  • Other Conditions Affecting Movement Any additional disorders or injuries that impair a patient's ability to move effectively.

2. Procedure

The procedure for comprehensive computer-based motion analysis involves several key steps to ensure accurate assessment and data collection. Each step is crucial for obtaining a complete understanding of the patient's movement dynamics.

  • Step 1: Preparation The patient is prepared for the motion analysis by placing markers on specific bony landmarks on the pelvis and lower extremities. This step is essential for tracking the patient's movements accurately during the analysis.
  • Step 2: Video Recording The patient walks in a designated area while multiple cameras capture their movements from the front, back, and both sides. This video recording is critical for visual analysis and further evaluation of gait patterns.
  • Step 3: Data Collection As the patient walks over force plates, data is collected regarding joint movement and power. Electronic sensors placed on the feet measure stride characteristics, providing additional insights into the patient's walking mechanics.
  • Step 4: Dynamic Plantar Pressure Measurement In this step, electronic sensors are placed on the patient's feet to record weight-bearing pressures on the bottom of the foot as they walk. This information is vital for understanding how the patient's weight is distributed during movement.
  • Step 5: Muscle Activity Monitoring Although this step is specifically associated with CPT® Code 96002, it is important to note that surface electrodes may also be used to monitor muscle activity in the lower extremities during functional activities, providing further data on muscle response and timing.

3. Post-Procedure

After the comprehensive computer-based motion analysis is completed, the physician or qualified healthcare professional reviews and analyzes the collected data. This analysis culminates in a written report detailing the findings, which is essential for guiding subsequent therapeutic decisions. The results of the motion analysis may inform the need for specific interventions, such as the selection of appropriate braces or prosthetics, or recommendations for surgical options. It is important to note that the analysis and reporting process is comprehensive, ensuring that all relevant data is considered in the development of a tailored treatment plan for the patient.

51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
