What G0317 covers
G0317 represents additional time spent by a physician or qualified health care professional on a nursing facility evaluation and management service. It may be relevant when an initial nursing facility assessment or a subsequent visit requires unusually extensive work, such as reviewing a complex medical record, evaluating the resident, discussing the plan with family or facility staff, and coordinating care. The additional time must be attributable to the nursing facility E/M service, not simply the time the clinician is present in the facility.
Report G0317 only with the qualifying primary nursing facility E/M service, 99306 or 99310, when documented total time exceeds the time represented by that primary service. Record the clinician’s qualifying work and total time for the date, separating time already counted toward the base visit from additional time. Each unit represents an additional 15 minutes, subject to the applicable time threshold. CMS classifies G0317 as an add-on code; payment is made with the primary procedure and within that procedure’s global period.

G0317 billing questions
Which nursing facility visit codes can be paired with G0317?
G0317 is paired with 99306 for qualifying initial nursing facility care or 99310 for qualifying subsequent care. It is not a stand-alone visit code.
When is G0317 appropriate instead of reporting a higher-level visit?
Use the applicable primary visit code based on the service and its selection criteria, then report G0317 only for qualifying additional time beyond the primary service’s time.
What time should the record support?
Document the clinician’s total qualifying time on the date of service and identify the work attributable to the additional time. Do not count time already used to select or support the primary visit.
Can G0317 be billed by itself?
No. It is an add-on code and must be billed with a qualifying primary nursing facility E/M service.
Does G0317 describe a separate procedure or facility service?
No. It reports additional clinician time for the nursing facility E/M service; it does not represent a separate procedure performed by facility staff.
