CPT code 99354,99355 , 99356, 99357

Prolonged Physician Service With Direct (Face-to-Face) Patient Contact

►Codes 99354-99357 are used when a physician provides prolonged service involving direct (face-to-face) patient contact that is beyond the usual service in either the inpatient or outpatient setting. This service is reported in addition to the designated evaluation and management services at any level and any other physician services provided at the same session as evaluation and management services. Appropriate codes should be selected for supplies provided or procedures performed in the care of the patient during this period.

Codes 99354-99355 are used to report the total duration of face-to-face time spent by a physician on a given date providing prolonged service, even if the time spent by the physician on that date is not continuous. Codes 99356- 99357 are used to report the total duration of unit time spent by a physician on a given date providing prolonged services to a patient, even if the time spent by the physician on that date is not continuous


Code 99354 or 99356 is used to report the first hour of prolonged service on a given date, depending on the place of service.

Either code should be used only once per date, even if the time spent by the physician is not continuous on that date. Prolonged service of less than 30 minutes total duration on a given date is not separately reported because the work involved is included in the total work of the evaluation and management codes.
