What is the primary requirement for reporting code 99360?

For reporting code 99360, the primary requirement is that the time must be documented as 30 minutes or more. This code is specifically used for services that involve standby care, where a physician is on standby and available to provide care if needed. The classification of this type of service relies heavily on the amount of time the physician is on standby. Documentation confirming that the standby period lasted at least 30 minutes is essential to substantiate the appropriate billing for this service. It emphasizes the importance of recording time accurately in order to comply with coding requirements for that specific service.

The other options, while they touch on important aspects of physician care, do not pertain to the primary requirement for reporting code 99360. For instance, the involvement of ongoing treatment during standby or having multiple physicians does not directly relate to the code's documentation requirement.
