Start with these three plays

The fastest wins from the whole guide, surfaced up front. Each links to the full explanation and the wording you can paste into a note.

New patient establishing ongoing care

Add G2211 on visits where you hold ongoing responsibility for the problem. It is not paid on ordinary procedure days when the visit carries modifier 25, though CMS allows narrow preventive exceptions such as the annual wellness visit.

Referred patient, no follow-up

A new patient visit can be a consultation when another clinician requested your opinion and your report goes back; many commercial payers value these higher, though policies vary.

A procedure plus a real evaluation

When you inject a joint and also evaluate the problem, code both with modifier 25. Show the evaluation stood on its own or addressed a separate diagnosis.
