How To Use CPT Code 73201

CPT 73201 describes the use of computed tomography (CT) with contrast material(s) to image the upper extremity. This article will cover the description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information, similar codes and billing examples.

1. What is CPT Code 73201?

CPT 73201 can be used to describe the use of CT with contrast material(s) to image the upper extremity. This code is used when a provider rotates an X-ray tube and X-ray detectors around the patient to produce cross-sectional images of the upper extremity. The CT scan helps diagnose, manage, and treat diseases affecting the upper extremity.

2. Official Description

The official description of CPT code 73201 is: ‘Computed tomography, upper extremity; with contrast material(s).’ This code represents the use of CT with contrast material(s) to image the upper extremity.

3. Procedure

1. The provider positions the patient on the scanner table and inserts an intravenous (IV) line for contrast administration.
2. The provider supervises the administration of the IV contrast and performs scout films or preliminary images.
3. The provider acquires the actual CT images of the upper extremity as the scanner moves around the body.
4. The images are displayed on a monitor screen for the provider to review and analyze.
5. The provider interprets the results and prepares a report of their findings.

4. Qualifying circumstances

CPT 73201 is used when a provider performs CT imaging of the upper extremity using contrast material(s). The contrast material can be administered intravenously, intraarticularly, or intrathecally. This code is appropriate when the CT scan is necessary to diagnose, manage, or treat diseases affecting the upper extremity.

5. When to use CPT code 73201

CPT code 73201 should be used when a provider performs CT imaging of the upper extremity with the use of contrast material(s). This code is not appropriate for CT scans of the upper extremity without the use of contrast. It is important to ensure that the contrast material is administered through the appropriate route (intravenous, intraarticular, or intrathecal) to accurately report CPT 73201.

6. Documentation requirements

To support a claim for CPT 73201, the provider must document the following information:

• Indication for the CT scan of the upper extremity
• Type and route of contrast material used
• Date and time of the procedure
• Images acquired and reviewed by the provider
• Interpretation and findings of the CT scan
• Preparation of a report documenting the results

7. Billing guidelines

When billing for CPT 73201, it is important to ensure that the provider performs CT imaging of the upper extremity with contrast material(s). If the provider only interprets the radiology service, append modifier 26 to the radiology code. If the provider only performs the technical component, append modifier TC to the radiology code. However, note that payer policies may exempt hospitals from appending modifier TC. It is also important to follow payer guidelines for reporting contrast separately, if applicable.

8. Historical information

CPT 73201 was added to the Current Procedural Terminology system on January 1, 1990. The code underwent a change on January 1, 2003, with the addition of ‘computed axial’ to the code description.

9. Examples

1. A radiologist performs a CT scan of the upper extremity with contrast material(s) to evaluate a suspected bone tumor.
2. An orthopedic surgeon orders a CT scan of the upper extremity with contrast material(s) to assess the extent of a soft tissue injury.
3. A rheumatologist utilizes CT imaging with contrast material(s) to diagnose and monitor a patient with inflammatory arthritis affecting the upper extremity.
4. An oncologist performs a CT scan of the upper extremity with contrast material(s) to evaluate lymph node involvement in a patient with suspected metastatic cancer.
5. A hand surgeon orders a CT scan of the upper extremity with contrast material(s) to assess the vascular supply in a patient with peripheral artery disease.
6. A trauma surgeon utilizes CT imaging with contrast material(s) to evaluate fractures and soft tissue injuries in a patient with upper extremity trauma.
7. An interventional radiologist performs a CT-guided biopsy of a suspicious lesion in the upper extremity using contrast material(s) for guidance.
8. A plastic surgeon orders a CT scan of the upper extremity with contrast material(s) to assess blood flow and tissue viability in a patient undergoing reconstructive surgery.
9. An infectious disease specialist utilizes CT imaging with contrast material(s) to evaluate the extent of an infection in the upper extremity.
10. A vascular surgeon performs a CT angiography of the upper extremity with contrast material(s) to assess blood vessel abnormalities in a patient with suspected vascular disease.
