Pulmonary Function Studies (July 2005)

Why This Topic Matters

Pulmonary function testing often involves multiple reportable elements, so updates to code descriptors and instructions can affect how services are captured and separated on claims. Understanding the article helps readers recognize the scope of the CPT changes and the broader reporting context for respiratory diagnostics.
