What 94727 covers

Code 94727 covers lung-volume measurement by gas dilution or washout, commonly using helium dilution or nitrogen washout in a pulmonary function laboratory. The test estimates functional residual capacity and derives residual volume and total lung capacity; respiratory therapists typically conduct the maneuver, with a clinician interpreting the results. Because the method measures gas that reaches communicating airways, its lung-volume results can differ from body plethysmography when air trapping is present.

Select 94727 when the documented method is gas dilution or washout, rather than the plethysmographic method reported with 94726. The record should identify the testing method, include the resulting lung-volume measurements, and support the interpreting clinician’s conclusions. CMS recognizes separately priced professional and technical components: use modifier 26 for interpretation, modifier TC for equipment and staff, or report without either modifier for the global service. Report the test service rather than separate units for each calculated volume.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

94727 billing questions

How does 94727 differ from 94726?

Code 94727 is for lung volumes measured by gas dilution or washout. Use 94726 for the plethysmographic method.

Can 94727 be reported with a diffusion-capacity test?

Yes. A gas-dilution lung-volume test and a diffusion-capacity test measure different pulmonary functions and may be performed during the same testing encounter.

Which modifiers identify the components?

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

Should each measured lung volume be reported as a separate unit?

No. Report the gas-dilution or washout test service, not separate units for functional residual capacity, residual volume, and total lung capacity.

What documentation supports 94727?

Document the gas-dilution or washout method, the resulting lung-volume measurements, and the clinician’s interpretation. The method helps distinguish this service from plethysmography.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
