What G0316 covers
G0316 represents additional physician or qualified health professional time spent on hospital inpatient or observation evaluation and management beyond the time for an eligible primary service. It may accompany an initial hospital care service, a subsequent hospital care service, or same-day admission and discharge care. The work may include continued assessment, review of clinical information, treatment planning, and coordination related to the patient’s hospital care. It is used for care in hospital inpatient and observation settings, not for prolonged nursing facility or home E/M services.
Report G0316 only with an eligible primary service, such as 99223, 99233, or 99236; it is not a stand-alone service. Select the primary E/M code under the applicable visit rules, then report G0316 for documented qualifying time beyond that service’s time threshold, in the additional intervals required for the add-on. Documentation should support the total time on the date of service and the work performed. CMS treats G0316 as an add-on paid within the primary procedure’s global period.

G0316 billing questions
Which primary E/M codes can be paired with G0316?
G0316 is reported with eligible hospital inpatient or observation care services, including 99223, 99233, and 99236. It cannot be submitted by itself.
When does the documented time support G0316?
The primary service’s time requirement must be met, with qualifying additional time beyond its threshold for each reported add-on interval. Document the total time and the work performed.
Can time for a separately billed service count toward G0316?
Do not count time spent on a separately reported service toward the prolonged E/M time. The documentation should make the time attributable to the E/M work clear.
Should G0316 be used for prolonged nursing facility care?
No. G0316 is for hospital inpatient or observation care; G0317 is the related prolonged-service code for nursing facility E/M.
How does CMS pay G0316?
CMS treats G0316 as an add-on code paid within the primary procedure’s global period. It must be billed with an eligible primary E/M service.
