Code 99360 is used to report physician or other qualified health care professional standby service that is requested by another individual and that involves prolonged attendance without direct (face-to-face) patient contact. Care or services may not be provided to other patients during this period. This code is not used to report time spent proctoring another individual. It is also not used if the period of standby ends with the performance of a procedure subject to a "surgical" package by the individual who was on standby.
