CPT® Code 0602T

Official Description

Glomerular filtration rate (GFR) measurement(s), transdermal, including sensor placement and administration of a single dose of fluorescent pyrazine agent

Common Language Description

The procedure described by CPT® Code 0602T involves the measurement of glomerular filtration rate (GFR) through a noninvasive transdermal method. This technique utilizes a specialized sensor device that is applied to the skin to assess kidney function. The primary purpose of GFR measurement is to monitor kidney health, evaluate kidney disease, and prevent misdiagnosis related to the staging of kidney conditions. Unlike traditional methods that require blood samples to estimate GFR, this procedure allows for real-time monitoring of kidney function without the need for invasive blood draws. The estimated GFR is a common clinical practice; however, it relies on serum creatinine levels, which can be influenced by various factors and may not provide timely or accurate reflections of kidney function. The transdermal sensor is designed to measure the actual clearance of a fluorescent pyrazine tracer agent, which is administered as a single intravenous bolus dose. This agent disperses into the extracellular space and is subsequently cleared by the kidneys, allowing for direct measurement of GFR. The sensor's technology includes a fiber optic bundle that captures and processes the emitted fluorescent light from the tracer, converting it into a digital readout for analysis. This innovative approach enhances the accuracy of kidney function assessments and provides valuable insights into renal health.

1. Indications

The glomerular filtration rate (GFR) measurement using CPT® Code 0602T is indicated for the following conditions:

Kidney Function Assessment - To evaluate the overall function of the kidneys and determine their ability to filter waste from the blood.
Monitoring Kidney Disease - To track the progression of kidney disease and assess the effectiveness of treatment interventions.
Preventing Staging Misdiagnosis - To ensure accurate staging of kidney disease, thereby preventing potential misdiagnosis that could lead to inappropriate management strategies.

2. Procedure

The procedure for GFR measurement using CPT® Code 0602T involves several key steps:

Preparation of the Sensor Site - The area of the skin where the transdermal sensor will be placed is first cleansed and shaved to ensure proper adhesion and accurate readings.
Attachment of the Sensor - A medical-grade two-sided adhesive is used to securely attach the transdermal sensor to the prepared skin surface, ensuring that it remains in place during the measurement process.
Administration of the Tracer Agent - A single dose of the fluorescent pyrazine tracer agent is administered as an intravenous bolus injection. This agent is crucial for the measurement of GFR as it allows for the tracking of kidney filtration in real-time.
Monitoring of GFR - After the tracer is administered, the sensor continuously monitors the clearance of the tracer from the body. The sensor contains a fiber optic bundle that captures the backscattered light and the fluorescent light emitted from the tracer, which is then processed to provide a digital readout of the GFR.
Data Analysis - The data collected by the sensor is amplified and converted from analog to digital format using custom software, allowing for precise analysis of the kidney's filtration capabilities as the tracer is cleared.

3. Post-Procedure

After the GFR measurement procedure is completed, the patient may be monitored for any immediate reactions to the tracer agent. The length of time for which monitoring can continue after tracer administration is contingent upon the health of the kidneys. It is essential to ensure that the sensor remains securely attached to the skin for accurate readings. Patients may be advised on any necessary follow-up appointments to discuss the results of the GFR measurement and any further actions required based on the findings. Additionally, healthcare providers may need to consider the implications of the results on the patient's overall kidney health and management plan.
