CMS Pub. 100-04, ch. 12, § 30.6.15.1
Prolonged Services – General Rules
Prolonged E/M services may be reported for certain E/M visit families, when the total visit
time spent by the practitioner exceeds a certain time threshold. Prolonged E/M services are
reported using Medicare-specific coding.
See section 30.6.18 for rules regarding billing of E/M visits that are split (or shared) and
involve prolonged service time.
30.6.15.2 Prolonged Office/Outpatient E/M Visits
(Rev. 11842; Issued; 02-09-23 Effective:01-01-23; Implementation: 05-09-23)
When the practitioner selects visit level using time, the practitioner may report prolonged
office/outpatient E/M visit time using HCPCS add-on code G2212 (Prolonged office/outpatient
E/M services). The following table provides reporting examples.
HCPCS Code(s) Total Time Required for Reporting*
99205 60-74 minutes
99205 x 1 and G2212 x 1 89-103 minutes
99205 x 1 and G2212 x 2 104-118 minutes
99215 40-54 minutes
99215 x 1 and G2212 x 1 69-83 minutes
99215 x 1 and G2212 x 2 84-98 minutes
99215 x 1 and G2212 x 3 or more for each
additional 15 minutes.
99 or more
*Total time is the sum of all time, including prolonged time, spent by the reporting practitioner
on the date of service of the visit.
HCPCS code G2212 (Prolonged office or other outpatient evaluation and management
service(s) beyond the maximum required time of the primary procedure which has been
selected using total time on the date of the primary service; each additional 15 minutes by the
physician or qualified healthcare professional, with or without direct patient contact (List
separately in addition to CPT codes 99205, 99215, 99483 for office or other outpatient
evaluation and management services). (Do not report G2212 on the same date of service as
99354, 99355, 99358, 99359, 99415, 99416). (Do not report G2212 for any time unit less than
15 minutes)).
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.
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.
