What G0318 covers
G0318 accounts for additional physician or qualified health care professional time spent on a prolonged evaluation and management service in a patient's home or residence. It is used with eligible high-level home or residence visits, such as a complex assessment in a private home or assisted living residence. The additional time may include work performed on the date of the visit with or without the patient present, consistent with the applicable E/M time rules.
Report G0318 only with an eligible primary home or residence E/M service, such as 99345 or 99350; it is not a standalone visit code. Select the primary service based on the applicable E/M criteria, and document total time and the work supporting the prolonged service. Each unit represents an additional 15 minutes. CMS classifies G0318 as an add-on code paid within the primary procedure's global period, so report it with that primary service rather than as a separate encounter.

G0318 billing questions
Which primary E/M codes can be paired with G0318?
G0318 is used with eligible high-level home or residence E/M services, including 99345 for a new patient and 99350 for an established patient.
Can G0318 be billed by itself?
No. CMS identifies it as an add-on code, so it must be reported with a qualifying primary home or residence E/M service.
How much time does one unit represent?
Each unit represents an additional 15 minutes of prolonged service time. Document the time and the work supporting the primary and prolonged services.
Can G0318 be used for a prolonged office visit?
No. G0318 is for prolonged home or residence E/M services. Prolonged office or outpatient E/M services use a different code pathway.
How does the global-period rule affect reporting?
CMS places payment for this add-on within the primary procedure's global period. Report G0318 with the primary home or residence E/M service, not as a separate encounter.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
