The visit complexity add-on is the most consistently missed 0.33 wRVU in outpatient medicine, and the documentation requirement is one honest sentence.
G2211 is a Medicare add-on to office and outpatient E/M visits recognizing the complexity of longitudinal care. It adds 0.33 wRVU to the visit, applies to new and established patients, and has no frequency limit. Many commercial payers now recognize it as well; check the payer.
The add-on belongs to visits that are part of continuing care: you are the focal point of the patient's care overall, or you are managing a specific condition on an ongoing basis. A single visit that begins that relationship qualifies; a one time consultation that returns the patient to the referring clinician does not, and neither does care with no planned follow up of any kind.
G2211 is not payable when the E/M visit is reported with modifier 25 for a same day procedure such as a joint injection. Since 2025, CMS pays G2211 despite modifier 25 when the modifier exists because the visit was furnished on the same day as a Medicare annual wellness visit, vaccine administration, or another Medicare Part B preventive service. A procedure day still excludes it.
Skipping it on fracture and postoperative follow ups that are coded as separately payable office E/M visits (nonoperative fracture care followed as E/M is the classic case); adding it to visits with a same day injection; and writing no follow up plan at all, which leaves the relationship undocumented. One sentence fixes the last one. The flip side matters just as much: G2211 attaches only to a payable 99202 to 99215 visit. A routine global period check (99024) is not an office E/M, and no add-on attaches to it; the encounter must first support a separately reportable visit before G2211 enters the question.
The E/M Coding Assistant checks G2211 eligibility on every note, adds the attestation sentence to the paste ready rationale, and tells you exactly why when the add-on is blocked.
