Official Description

Radiologic examination, complex motion (ie, hypercycloidal) body section (eg, mastoid polytomography), other than with urography; unilateral

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A radiologic examination that utilizes complex motion techniques, such as hypercycloidal imaging, is performed to obtain detailed images of a specific body section. This procedure employs advanced imaging technology, typically involving a machine equipped with multiple scanning heads. These heads capture images of several predetermined planes in rapid succession, which helps to eliminate distortion that may arise from internal movement during the imaging process. The resulting scan generates a digital three-dimensional representation of the targeted body area, providing valuable insights for diagnostic purposes. This type of examination is particularly useful in identifying various articular disorders, including conditions like ankylosis, congenital or developmental abnormalities, fractures, joint dislocations, inflammatory diseases, and osteoarthritis. Additionally, it can assist in diagnosing masticatory muscle disorders, which encompass issues such as myofascial pain, myofibrotic contractures, myospasm, and neoplasia. The specific CPT® code 76101 is designated for reporting unilateral radiologic examinations of complex motion, while code 76102 is reserved for bilateral examinations, both of which exclude urography.

1. Indications

The radiologic examination coded as 76101 is indicated for various conditions that require detailed imaging of a body section to assist in diagnosis. The following are the explicitly provided indications for this procedure:

  • Articular Disorders These include conditions such as ankylosis, which is the abnormal stiffening and immobility of a joint due to fusion of the bones, and other joint-related issues.
  • Congenital or Developmental Disorders These are abnormalities present from birth or those that develop during growth, affecting the structure and function of the body.
  • Fractures The examination can help in identifying and assessing the extent of bone fractures in the targeted area.
  • Joint Dislocations This procedure aids in visualizing dislocated joints to determine the best course of treatment.
  • Inflammatory Disorders Conditions characterized by inflammation in the joints or surrounding tissues can be evaluated through this imaging technique.
  • Osteoarthritis This degenerative joint disease can be assessed to understand the extent of joint damage and inform treatment options.
  • Masticatory Muscle Disorders This includes conditions such as myofascial pain, myofibrotic contractures, myospasm, and neoplasia, which affect the muscles involved in chewing and jaw movement.

2. Procedure

The procedure for conducting a complex motion radiologic examination involves several key steps, which are outlined as follows:

  • Step 1: Patient Preparation The patient is positioned appropriately to ensure that the area of interest is adequately exposed for imaging. This may involve adjusting the patient's posture or using supports to maintain stability during the scan.
  • Step 2: Equipment Setup The imaging machine, equipped with multiple scanning heads, is calibrated and set up to capture images of the predetermined planes. The technician ensures that all necessary settings are adjusted for optimal image quality.
  • Step 3: Image Acquisition The machine initiates the scanning process, capturing images in rapid succession. This complex motion technique allows for the creation of a three-dimensional image while minimizing distortion from any internal movement.
  • Step 4: Image Processing Once the images are acquired, they are processed to generate a digital representation of the body section. This may involve using specialized software to enhance image clarity and detail.
  • Step 5: Interpretation The resulting images are then reviewed by a radiologist or qualified healthcare professional, who interprets the findings and prepares a report detailing any abnormalities or conditions identified during the examination.

3. Post-Procedure

After the complex motion radiologic examination is completed, the patient may be monitored briefly to ensure there are no immediate adverse effects from the procedure. Typically, there are no specific post-procedure care requirements, and patients can resume their normal activities unless otherwise instructed by their healthcare provider. The radiologist will provide a detailed report of the findings, which will be communicated to the referring physician for further evaluation and management of any identified conditions. Follow-up appointments may be scheduled based on the results of the examination and the patient's clinical needs.
