About G0545: Inpatient visit complexity add-on
Add-on for the added complexity of eligible inpatient or observation evaluation and management visits involving patients with serious or complex conditions.
G0545 recognizes the added work inherent in certain hospital-based evaluation and management visits for patients with serious or complex conditions. It is relevant to hospitalists, internists, and other clinicians managing these patients during an inpatient or observation stay. The primary service is the actual evaluation and management encounter; G0545 represents the additional complexity associated with that visit, not a separate patient encounter.
Report G0545 only with an eligible primary service, such as an initial or subsequent inpatient or observation care visit, when the visit meets the add-on’s requirements. Documentation should support the primary E/M service and describe the serious or complex condition and the work involved in managing it during the stay. CMS classifies G0545 as an add-on code: it is billed with a primary procedure and paid within that procedure’s global period.
