About the XX2 Code Range
These procedures repeatedly measure functions over time, including blood flow, brain electrical activity, glucose and fluid volume between cells, and muscle compartment pressure.
The fourth character identifies the area: Central Nervous, Circulatory, Musculoskeletal or Subcutaneous Tissue. The fifth distinguishes a percutaneous approach, through a puncture or small incision, from an external approach at or through the skin. The sixth pairs each measurement with its technology, such as an adhesive ultrasound patch for blood flow or a wearable sensor for glucose between cells. The seventh identifies New Technology Group 9, New Technology Group 10 or New Technology Group 11.
