30.6.15.3 Prolonged Other E/M Visits
(Rev. 11842; Issued; 02-09-23 Effective:01-01-23; Implementation: 05-09-23)
Beginning January 1, 2023, prolonged Other E/M visit services are reported as discussed in this
section. Other E/M visits include inpatient/observation visits, nursing facility visits,
home/residence visits, and cognitive impairment assessment and care planning. Prolonged
Other E/M services may be reported with the highest visit level, for timed visits, when the total
visit time spent by the practitioner exceeds a certain time threshold.
Prolonged services are not reported in conjunction with emergency department visits or critical
care services.
Prolonged services are created to provide payment for additional practitioner time that is not
already accounted for in the valuation of the primary service. Accordingly, practitioner time
spent in qualifying activities can be counted when performed on any date within the surveyed
timeframe for the visit, and when the total time (in the physician time file) is exceeded by 15 or
more minutes. We show this in the following table.

* Time must be used to select visit level. Prolonged service time can be reported when
furnished on any date within the primary visit’s surveyed timeframe and includes time with or
without direct patient contact by the physician or NPP. Consistent with CPT’s approach, we do
not assign a frequency limitation.
Qualifying activities are listed in the CPT Codebook’s E/M Service Guidelines (Guidelines for
Selecting Level of Service Based on Time). These activities may be counted when time is used
to select visit level, when performed and medically reasonable and necessary.
