Flow volume loop repeated after a bronchodilator: the post-bronchodilator study that follows J304.

What it covers

J304 is a volume-versus-flow study (flow volume loop) generating an expiratory limb, and an inspiratory limb if indicated. J327 is the repeat study after a bronchodilator (H4).

Pulmonary function tests have a professional component (supervision, interpretation) and a technical component (performing the test, records, a signed written report to the referring provider) (H1–H2).

Billing rules

• Technical (T, suffix B) and professional (P, suffix C) components are claimed separately (H3).
• Unlike most pulmonary function tests, the technical component is payable in the office (H3). In hospital it is paid at 86.10% of the T fee, and never for in-patients or patients admitted to the same hospital within 24 hours for the same condition (GP11).
• Not payable with J301 or J324 for the same patient on the same day (H4).
• The result must be the best of three recorded tests, or the study is not eligible for payment (H4).
• Needs a permanent record with a written physician interpretation and scaled graphs or tracings (5 mm per litre per second for flow, 10 mm per litre for volume) (H4).
• The physician claiming the professional component must be able to show training in interpretation; automated interpretation alone doesn't qualify (H4).
• Can be delegated to trained office staff, even with the physician off site, for your own patient, with chart documentation of who did it (GP62–GP63).
• FHO: J327C is an in-basket (Schedule 2) code (Agreement p.78).

Often billed with

• J304 flow volume loop before the bronchodilator (H4).

Common rejections

• ADH: J327 was billed the same day as J301 or J324 for the same patient; these cannot be billed together (H4).
