Invasive Sensor for Artificial Pancreas Device System (HCPCS S1035)

Name of the Procedure:

Common Name(s): Invasive Glucose Sensor, Subcutaneous Sensor for Artificial Pancreas
Technical/Medical Term: Invasive Subcutaneous Sensor for Artificial Pancreas Device (HCPCS S1035)

Summary

An invasive sensor is a tiny device that is placed under the skin to continuously monitor blood glucose levels. It is designed to work with an artificial pancreas system, which helps regulate insulin delivery for people with diabetes, particularly those with type 1 diabetes.

Purpose

The primary purpose of the invasive sensor is to continuously track blood glucose levels. It helps in managing diabetes more effectively by automatically adjusting insulin delivery through an artificial pancreas system. The goal is to maintain optimal blood glucose levels, reducing the risk of complications and improving the quality of life.

Indications

• Patients with type 1 diabetes.
• Individuals who have difficulty maintaining stable blood glucose levels.
• Patients who experience frequent episodes of hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar).

Preparation

• Patients may need to fast for a few hours prior to sensor insertion.
• Blood glucose levels will be checked before the procedure.
• Inform the healthcare provider of any medications being taken; some might need adjustment.
• The skin at the insertion site should be clean and free of lotions or oils.

Procedure Description

1. A small area of the skin is sterilized and, if necessary, numbed with a local anesthetic.
2. The sensor is then inserted under the skin using a special applicator or needle.
3. The sensor is connected to an artificial pancreas system or insulin pump via a small transmitter.
4. The provider will check that the sensor is functioning correctly and provide instructions on how to monitor the data it provides.

Duration

The insertion process typically takes around 15 to 30 minutes.

Setting

The procedure is usually performed in a doctor's office, diabetes clinic, or outpatient facility.

Personnel

• Endocrinologist or diabetes specialist
• Trained nurse or medical technician
• Diabetes educator (for post-procedure care and instructions)

Risks and Complications

• Minor risk of infection at the insertion site.
• Potential skin irritation or allergic reaction to the adhesive or sensor materials.
• Rarely, the sensor may malfunction or provide inaccurate readings.
• Bleeding or bruising at the insertion site.

Benefits

• Continuous glucose monitoring provides more precise control of blood glucose levels.
• Reduction in the frequency of severe hypoglycemia or hyperglycemia episodes.
• Improved overall diabetes management and quality of life.

Recovery

• Patients can usually resume normal activities immediately after the procedure.
• Keep the insertion site clean and dry to avoid infection.
• Regularly check the sensor to ensure it is secure and functioning properly.
• Follow-up appointments may be necessary to review data and adjust treatment plans.

Alternatives

• Fingerstick blood glucose testing multiple times a day.
• Non-invasive glucose monitoring devices (though they may be less accurate).
• Manual insulin management using traditional insulin pumps or injections.

Patient Experience

• During the procedure, patients might feel a brief sting or pinch when the sensor is inserted.
• Some discomfort or skin irritation might occur at the insertion site.
• Most patients adapt quickly to wearing the sensor and find it convenient.
• Proper pain management and adhesive techniques can enhance comfort.
