After-hours time premium 03.01AA in active treatment hospitals, nursing homes or auxiliary hospitals

The after-hours time premium is paid in addition to insured services provided in active treatment hospitals, nursing homes or auxiliary hospitals.  The criteria are as follows:

  • Patient must have been seen on the same date of service.
  • Activities that are included in claiming for time: charting, reviewing but not waiting for lab or DI results, consulting with other health providers on the service about the patients care, writing a referral/consultant letter and any other activities that are included in managing the patients’ care. 
  • To be billed at the start of the encounter or during the time period where the bulk of the time was spent (e.g., for starting the encounter at 21:55 and ending at 22:10, claim 03.01AA TNTP01).
  • If the time spent managing patients crosses over two time periods, more than one modifier can be used (e.g., for starting at 21:00 and ending at 23:45, claim 03.01AA TEV04 TNTP07).
  • If the time spent managing patient care crosses two dates of service, separate the claim into two claims with two dates of service (e.g., for starting on day one at 21:00 and ending on day two at 03:45, claim 03.01AA TEV04 TNTP08 for day one, and 03.01AA TNTA15 for day two).

03.01AA may not be claimed for the following:

  • Stand-by time.
  • Completing discharge summaries or clinical notations, unless the patient was seen on that day.
  • More than 4 units per hour per physician may not be claimed. Time claimed cannot exceed actual time spent managing patient care.
  • Providing uninsured services.
