Question:

"Transcutaneous oxygen assessment. Skin was prepped & fixator rings were placed at left chest 2nd intercostal reference site & distributed for 8 sites in a medial & lateral mapping formation of the rt lower extremity. Clarke-type polarographic electrodes were then calibrated at 45 degrees Celsius paced on fixator rings & allowed to equilibrate w/subjacent tissue over 20 min. Measurements performed while patient breathed normobaric room air and again during oxygen challenge. A regional perfusion index is calculated for each site using baseline equilibrated values relative to reference site." There is no mention of ABIs specifically. How would you code this?
