Pulmonary function testing

About 94728: Airway resistance oscillometry test

Measures respiratory resistance and related mechanics during quiet breathing with oscillometry, often as part of evaluating obstructive airway symptoms or disease.

Oscillometry assesses respiratory-system mechanics by applying small pressure oscillations while the patient breathes quietly through a mouthpiece. The test measures airway resistance and related responses without requiring repeated forceful expiratory maneuvers. Pulmonary function laboratories commonly perform it under the direction of pulmonologists, allergists, or other clinicians evaluating conditions such as asthma or obstructive lung disease; it can also provide measurements when a patient has difficulty completing effort-dependent testing.

Report 94728 for the oscillometry test itself, not for spirometry, lung-volume measurement, or gas-transfer testing. Documentation should identify the test performed and include the recorded results and the interpreting clinician’s findings. CMS recognizes a professional component, reported with modifier 26 for interpretation, and a technical component, reported with modifier TC for equipment and staff. Reporting the code without either modifier represents the global service, including both components.

94728 billing questions

How is oscillometry different from spirometry?

Oscillometry measures respiratory mechanics during quiet breathing using applied pressure oscillations. Spirometry measures airflow and volume during breathing maneuvers, including forced expiration.

Can 94728 be reported with lung-volume testing?

Yes, when oscillometry and a distinct lung-volume test are both performed and documented. The lung-volume service is separate from the oscillometry measurement.

What do modifiers 26 and TC represent?

Modifier 26 identifies the professional interpretation, while modifier TC identifies the technical service, including equipment and staff. Without either modifier, 94728 represents the global service.

What documentation supports reporting 94728?

Document that oscillometry was performed, the results obtained, and the clinician’s interpretation. For component billing, the record should support the professional or technical service represented by the modifier.

Is airway resistance by oscillometry the same as lung-volume measurement?

No. Oscillometry evaluates respiratory-system mechanics during quiet breathing; lung-volume tests measure volumes of air in the lungs using a different testing method.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
