How To Use CPT Code 93702

CPT 93702 describes the use of bioimpedance spectroscopy (BIS) to analyze extracellular fluid for lymphedema assessment. 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 93702?

CPT 93702 can be used to describe the non-invasive procedure of bioimpedance spectroscopy (BIS) for lymphedema assessment. This code is used when a healthcare provider measures the resistance of tissues in the limbs to a mild electric current and determines the volume of extracellular fluid. By analyzing the data obtained from BIS, the provider can detect early signs of lymphedema and take preventive action.

2. Official Description

The official description of CPT code 93702 is: ‘Bioimpedance spectroscopy (BIS), extracellular fluid analysis for lymphedema assessment(s).’ This code is used specifically for the analysis of extracellular fluid using BIS to assess lymphedema.

3. Procedure

1. The healthcare provider applies electrodes on the wrists or ankles of the patient.
2. A mild electric current is passed through the electrodes to measure the resistance of the tissues.
3. The provider analyzes the resistance data obtained at one or more frequencies.
4. Using an established equation, the provider converts the data to determine the fluid levels in the tissues.
5. The unaffected limb serves as a control or baseline for comparison.
6. The provider compares the result for the affected limb to the baseline to assess the presence of lymphedema.

4. Qualifying circumstances

CPT 93702 is used for patients who require lymphedema assessment. Lymphedema is the accumulation of fluid in the tissues, typically caused by a disorder of the lymphatic system or kidneys. The procedure is performed using bioimpedance spectroscopy (BIS) to analyze the extracellular fluid levels in the tissues. It is important to note that CPT code 93702 is not used for whole body composition analysis or physiological cardiovascular analysis.

5. When to use CPT code 93702

CPT code 93702 should be used when a healthcare provider performs extracellular fluid analysis using bioimpedance spectroscopy (BIS) specifically for lymphedema assessment. It is not appropriate to use this code for other types of analysis or assessments.

6. Documentation requirements

To support a claim for CPT 93702, the healthcare provider must document the following information:

• Patient’s diagnosis or indication for lymphedema assessment
• Details of the procedure, including the use of bioimpedance spectroscopy (BIS)
• Date of the procedure
• Results of the analysis, including the comparison to the baseline
• Signature of the healthcare provider performing the procedure

7. Billing guidelines

When billing for CPT 93702, ensure that the procedure involves the use of bioimpedance spectroscopy (BIS) for extracellular fluid analysis specifically for lymphedema assessment. It is important to note that CPT code 93702 should not be reported with other codes for whole body composition analysis or physiological cardiovascular analysis.

8. Historical information

CPT 93702 was added to the Current Procedural Terminology system on January 1, 2015. There have been no updates to the code since its addition.

9. Examples

1. A healthcare provider using bioimpedance spectroscopy (BIS) to assess extracellular fluid levels in the limbs of a patient with suspected lymphedema.
2. A provider performing BIS to analyze extracellular fluid in the affected limb of a patient who has undergone lymph node removal surgery.
3. A healthcare professional using BIS to monitor extracellular fluid changes in a patient receiving treatment for lymphedema.
4. A provider utilizing BIS to assess extracellular fluid levels in the limbs of a patient at risk for developing lymphedema.
5. A healthcare provider performing BIS to analyze extracellular fluid in the limbs of a patient with a known lymphatic disorder.
6. A provider using BIS to assess extracellular fluid levels in the limbs of a patient with kidney dysfunction and suspected lymphedema.
7. A healthcare professional utilizing BIS to monitor extracellular fluid changes in a patient undergoing lymphedema treatment.
8. A provider performing BIS to analyze extracellular fluid in the limbs of a patient with a history of lymphedema.
9. A healthcare provider using BIS to assess extracellular fluid levels in the limbs of a patient with a recent injury that may have affected lymphatic drainage.
10. A provider utilizing BIS to monitor extracellular fluid changes in a patient with a family history of lymphedema.
