What 94010 covers
The patient inhales fully and then exhales as hard and as long as possible into a spirometer. The test records forced vital capacity, FEV1, the FEV1/FVC ratio, and expiratory flow rates, with a volume-time or flow-volume tracing. Maximal voluntary ventilation may also be measured as part of the service. Respiratory therapists, pulmonary function technologists, or trained office staff perform testing in pulmonary and primary care offices, hospital pulmonary function labs, and occupational health clinics. A pulmonologist or other qualified clinician interprets the results. Common uses include COPD and asthma evaluation, preoperative assessment, and monitoring of known restrictive lung disease.
Report one unit for a standard spirometry study; repeated efforts to obtain acceptable results are part of that study. If spirometry is repeated after an administered bronchodilator to assess response, report the response study instead. Documentation should include tracings, effort quality and reproducibility, measured and predicted values, and a signed interpretation. CMS prices the professional and technical components separately: modifier 26 identifies interpretation, while modifier TC identifies equipment and staff services. An entity furnishing both components reports the global service without a component modifier.

How to choose
- 94060Bronchodilator spirometry
- 94060 covers spirometry before and after bronchodilator administration to assess response. If only a baseline spirometry study is performed, report 94010.
- 94070Wheezing evaluation
- 94070 covers bronchial provocation with serial spirometry, such as a methacholine challenge. A standard spirometry study without provocation is 94010.
- 94011Infant spirometry
- 94011 describes infant spirometry for children through age 2. Code 94010 describes standard spirometry performed with the patient's own forced expiratory effort.
- 94016Spirometry review
- 94016 is review and interpretation of patient-initiated spirometry recorded over time. Code 94010 is a supervised standard spirometry study.
94010 billing questions
Can 94010 be billed with 94060 on the same date?
Do not report 94010 for the baseline measurements included in the same pre- and post-bronchodilator study. Report 94060 for that study.
When should modifier 26 or TC be appended?
Use modifier 26 for interpretation only, such as when a physician interprets a test performed in a hospital pulmonary function lab. Modifier TC identifies the equipment and staff portion when that component is billed separately.
Is maximal voluntary ventilation billed separately?
No. Maximal voluntary ventilation is included in 94010 when performed as part of the spirometry study.
Can DLCO be added to spirometry?
Yes. When diffusing capacity is measured with the spirometry study, report add-on code 94729 with 94010.
What documentation supports the interpretation component?
The written report should address test quality and acceptability, compare results with predicted values, and state a clinical impression. Raw printouts without a signed interpretation do not support modifier 26.
Which code is used for spirometry in a toddler?
Code 94011 describes infant spirometry for children through 2 years of age. Code 94010 describes standard spirometry using the patient's own forced expiratory effort.
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.
