Answer: When the oncologist or nurse refills or maintains an intrathecal, epidural or intraventricular pump or reservoir, you can choose between 95990 (Refilling and maintenance of implantable pump or reservoir for drug delivery ...) and 95991 (... administered by a physician).
You should use 95991 when your oncologist refills or maintains the pump. But you should assign 95990 when another professional, such as a nurse, provides the pump service.
