What 99360 covers
99360 represents physician standby: a physician remains available to intervene if needed rather than furnishing the planned procedure or participating in a care-planning conference. The physician providing the standby service reports it. The code is counted in 30-minute increments and describes availability for a possible intervention, not prolonged work performed without patient contact. It is distinguished from conference participation and prolonged non-contact work by what the physician is doing during the reported time.
Medicare assigns status X, a statutory exclusion from physician fee schedule payment because this is not a physician service under the Medicare statute. When covered, it is paid under another fee schedule or payment system. Report one unit for each 30-minute increment of standby service.
