How To Use CPT Code 0448T

CPT 0448T describes the procedure for the removal of an implantable interstitial glucose sensor and the creation of a subcutaneous pocket at a different anatomic site for the insertion of a new sensor. This article will cover the description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information, and examples.

1. What is CPT Code 0448T?

CPT 0448T can be used to describe the removal of an implantable interstitial glucose sensor and the creation of a subcutaneous pocket at a different location for the insertion of a new sensor. This code is used when the provider performs the procedure to replace the sensor and activate the system, while also training the patient on its use.

2. Official Description

The official description of CPT code 0448T is: ‘Removal of implantable interstitial glucose sensor with creation of subcutaneous pocket at different anatomic site and insertion of new implantable sensor, including system activation.’

3. Procedure

1. The provider prepares the patient for the procedure, which can be performed in the office setting.
2. Using local anesthesia, the provider opens the incision over the previously implanted sensor and removes it.
3. A new incision is made in a different location, possibly on the patient’s other arm, and a subcutaneous pocket is created.
4. The provider inserts the sensor of an interstitial continuous glucose monitoring system into the pocket and closes the incision.
5. A rechargeable device is placed over the area to power the implant, and a transmitter is placed on top of the skin to receive and transmit glucose levels.
6. The provider activates the system and trains the patient on how to use the device for continuous glucose monitoring.

4. Qualifying circumstances

Patients who may require CPT 0448T are those with an implantable interstitial glucose sensor that needs to be replaced. This procedure is performed to ensure continuous glucose monitoring for patients with diabetes or other conditions that require close monitoring of glucose levels. The patient must be under the care of a provider who is qualified to perform the procedure and provide the necessary training.

5. When to use CPT code 0448T

CPT code 0448T should be used when the provider performs the removal of an implantable interstitial glucose sensor, creates a subcutaneous pocket at a different anatomic site, and inserts a new sensor. This code should be reported for each instance of the procedure performed.

6. Documentation requirements

To support a claim for CPT 0448T, the provider must document the following information:

• Patient’s diagnosis and the need for the removal and replacement of the sensor
• Details of the procedure, including the locations of the incisions and the creation of the subcutaneous pocket
• Date and time of the procedure
• Activation of the system and training provided to the patient
• Signature of the provider performing the procedure

7. Billing guidelines

When billing for CPT 0448T, ensure that the procedure is performed by a qualified provider and includes the removal of the sensor, creation of a subcutaneous pocket, insertion of a new sensor, system activation, and patient training. Do not report CPT 0448T in conjunction with CPT codes 0446T and 0447T. If the procedure involves the placement of a non-implantable interstitial glucose sensor without a pocket, use CPT code 95250.

8. Historical information

CPT 0448T was added to the Current Procedural Terminology system on January 1, 2017. There have been no updates to the code since its addition.

9. Examples

1. A provider removes an implantable interstitial glucose sensor from a patient’s upper arm, creates a new subcutaneous pocket on the opposite arm, and inserts a new sensor. The provider activates the system and trains the patient on its use.
2. A patient with diabetes undergoes the removal of an implantable interstitial glucose sensor from their abdomen. The provider creates a subcutaneous pocket on the patient’s thigh and inserts a new sensor. The system is activated, and the patient is trained on how to use it for continuous glucose monitoring.
3. A provider replaces an implantable interstitial glucose sensor in a patient’s leg. The previous sensor had malfunctioned, and a new sensor is inserted into a subcutaneous pocket created by the provider. The system is activated, and the patient is educated on its use.
4. A patient with a history of gestational diabetes has an implantable interstitial glucose sensor removed from their lower back. The provider creates a new subcutaneous pocket on the patient’s arm and inserts a new sensor. The system is activated, and the patient is provided with training on how to monitor their glucose levels.
5. A provider performs the removal of an implantable interstitial glucose sensor from a patient’s forearm. A new subcutaneous pocket is created on the patient’s chest, and a new sensor is inserted. The system is activated, and the patient is instructed on how to use it for continuous glucose monitoring.
6. A patient with type 1 diabetes undergoes the removal of an implantable interstitial glucose sensor from their upper arm. The provider creates a subcutaneous pocket on the patient’s abdomen and inserts a new sensor. The system is activated, and the patient is trained on its use for continuous glucose monitoring.
7. A provider replaces an implantable interstitial glucose sensor in a patient’s thigh. The previous sensor had reached the end of its lifespan, and a new sensor is inserted into a subcutaneous pocket created by the provider. The system is activated, and the patient is educated on how to monitor their glucose levels.
8. A patient with insulin resistance has an implantable interstitial glucose sensor removed from their lower abdomen. The provider creates a new subcutaneous pocket on the patient’s upper arm and inserts a new sensor. The system is activated, and the patient is provided with training on how to use it for continuous glucose monitoring.
9. A provider performs the removal of an implantable interstitial glucose sensor from a patient’s leg. A new subcutaneous pocket is created on the patient’s lower back, and a new sensor is inserted. The system is activated, and the patient is instructed on how to use it for continuous glucose monitoring.
10. A patient with uncontrolled diabetes undergoes the removal of an implantable interstitial glucose sensor from their upper arm. The provider creates a subcutaneous pocket on the patient’s abdomen and inserts a new sensor. The system is activated, and the patient is trained on its use for continuous glucose monitoring.
