Definition
An individual who is trained and qualified to perform pulmonary diagnostic tests. In the course of conducting these tests, the Pulmonary Function Technologist is able to setup, calibrate, maintain, and ensure the quality assurance of the pulmonary function testing equipment. In the laboratory, clinical or patient care setting the technologist instructs patients, elicits cooperation, performs procedures, monitors patient response, and evaluates patient performance. Tests results are calculated, compared with predicted normal ranges, and evaluated for reliability. The technologist collects clinical history data and evaluates the clinical implications of the test results.

Choose 2279P1006X over the general Respiratory Therapist, Registered code (227900000X) when the provider's training or certification is specifically in pulmonary function technologist; the general code covers the classification as a whole. A provider may report more than one taxonomy code on an NPI but marks one as primary.
Medicare
2279P1006X has no entry in the CMS Medicare Provider and Supplier Taxonomy Crosswalk. That usually means Medicare does not enroll this kind of provider under its own specialty — the provider can still hold an NPI and use this code on claims to other payers.

Using 2279P1006X
The code goes in the taxonomy field of the NPI application in NPPES, and on claims where a payer asks for it — box 24J (shaded) or 33b on the CMS-1500 with the ZZ qualifier, or the PRV segment of an 837 electronic claim. Payers match it against the taxonomy on the NPI record and, for Medicare, against the specialty on the enrollment, so all three should agree. To see which code a provider uses, search their NPI in the lookup.
