Below is excert from AMA CPT Assistant 2012, where they describe the use of image guidance for pump refill:
"A patient with a history of osteoporosis and multiple compression fractures presents to the clinic for a refill of her implanted spinal opioid delivery system. She meets with the physician, complains of slight worsening of pain since her last visit, and requests that the dosage be increased. The physician performs the refill and reprograms the pump with a 10% increase in daily dosage. The physician does not prescribe any medication and does not manage any other medical issues.
How to Code
CPT code 62370 is reported by the physician when the skill of the physician is required to perform the electronic analysis, sterile aspiration and measurement of the residual volume of solution, and refill, via Huber needle, into the pump reservoir septum. The pump is then reprogrammed to adjust the rate of infusion and control the increased level of pain. The pump alarm settings and reservoir levels are programmed as well as any changes made to the drug infusion concentration, rate, or mixture services. Refill date estimates are also made. No E/M code is reported for this scenario.
The performance of the services that will potentially require the skill of the physician or other qualified health care professional is reported with terminology that specifies "requiring physician skill." The use of these higher skill codes is typically associated with patients for whom access is difficult or painful due to presence of scar tissue or myofascial or other disease in the same area as the port. If intravenous sedation or fluoroscopy is needed to adequately identify the pump and refill port and/or use of instrumentation is needed to find and hold the pump in place, these would be aspects of patient care that would typically require the skill and knowledge of a physician."
