Breathing Circuits - Billing Instructions
Original Effective Date: 10/01/2000
Revision Effective Date: 11/01/2013
Code A4618 describes the breathing circuit used with a volume ventilator (E0450) (see below). A breathing circuit is a series of hoses and connectors that deliver the "breath" generated by the ventilator to the patient. Breathing circuits are not used with oxygen equipment or nebulizers; therefore, do not bill code A4618 for accessories used with these devices.
While code A4618 describes a breathing circuit for use with a ventilator, it is not separately reimbursable since code E0450 is in the frequent and substantial servicing payment category. Claims for A4618 when billed with an E0450 will be denied as not separately payable.
