Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with an implanted subcutaneous or intrathecal drug pump reservoir (for example, an intrathecal baclofen pump or an implanted chemotherapy or pain management pump) who presents for a scheduled refill. The patient arrives at an outpatient infusion center or ambulatory surgery center for a routine reservoir refill and pump check. The clinical workflow: verify patient identity and consent; review recent medication dosing and pump interrogation history; prepare sterile field and draw appropriate medication concentration; access reservoir with a refill needle under sterile technique; withdraw residual reservoir volume if required and inject prescribed drug volume; confirm pump function by aspirating or flushing and performing a reservoir/tubing integrity check; document lot numbers, volumes, and patient tolerance; observe patient for immediate adverse reaction and provide post-procedure instructions. Typical encounter duration ranges from 15 to 60 minutes depending on complexity and monitoring requirements. Typical site of service: outpatient infusion center, physician office, or ambulatory surgery center. Service type: injection/refill of implantable pump reservoir with device function check.
