99354 isn't used with office E/M visits. Since this is a Medicare Advantage plan I assume G2212 is appropriate: 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 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).
No modifier required.
