Bill 94010 and 94060 together at your own peril.
Dealing with pulmonary function test (PFT) codes can be deceptive as you navigate through simple looking codes that may come back to haunt you if make single slip and lose valuable dollars. Familiarize yourself with when to use the right CPT® codes for PFT by busting these myths.
Background: Whenever your pulmonologist treats a patient with suspected or known lung disease (such as emphysema), you are definitely in the mix for a possible use of PFT codes. The physician will need the PFTs along with meticulous history and physical examination for diagnosing the patient’s lung condition and pinpointing the disease from many.
What it is: PFT is a collective term loosely translated to a group of procedures — namely, spirometry, lung volume test, diffusion capacity test, lung compliance test, and exercise tolerance testing.
The fundamental PFT is a spirometry that measures lung volume and function (the rate at which you blow air in and out). You normally report spirometry with code 94010 (Spirometry, including graphic record, total and timed vital capacity, expiratory flow rate measurement[s], with or without maximal voluntary ventilation).
Another common test is the bronchospasm test, an extended form of spirometry. First, a spirometry test is performed, then the physician administers a bronchodilator (such as an albuterol inhaler) to dilate the airways, after which another spirometry would be done. The code for this procedure is 94060 (Bronchodilation responsiveness, spirometry as in 94010, pre- and post-bronchodilator administration).
The following case studies illustrate how to code for PFTs:
Insert All Possible Diagnoses to Justify Visit and Tests
Case #1: A patient with chronic obstructive pulmonary disease presents to the office with a variety of symptoms, including shortness of breath, wheezing, and breathlessness. After a thorough patient interaction, the pulmonologist decides to perform numerous in-office tests to properly diagnose the severity of the disease, including bronchospasm evaluation, diffusing capacity test, and thoracic gas volume test. He also orders a chest x-ray.
Code this: In this case, you should report the following:
Caution: “The radiologist should bill for the x-ray (71010, Radiologic examination, chest; single view, frontal), but you should include your informal physician’s review of the x-ray interpretation in your documentation for credit in the complexity of your medical decision making,” informs Carol Pohlig, BSN, RN, CPC, ACS, Senior Coding & Education Specialist at the Hospital of the University of Pennsylvania.
Remember to Include Inhalation Solution Codes While Billing
Case #2: A 55-year-old new patient who has been smoking for 30 years with shortness of breath is referred to your pulmonologist for consult. The physician performs a detailed history and an expanded problem-focused exam, and decides that spirometry would help diagnose COPD. The patient has non-optimal readings on the first spirometry, so the physician administers albuterol and re-performs the spirometry. Readings from the second test are greatly improved. The pulmonologist diagnoses the patient with reactive airway disease and probable COPD.
Code this: You should bill:
Hint: The correct code here is 94060 because the spirometry has turned into a bronchospasm test because the physician used an albuterol inhaler during the evaluation. The bronchospasm evaluation (94060) involves spirometry (94010) taken before and after your physician administers bronchodilation (94640, Pressurized or nonpressurized inhalation treatment for acute airway obstruction or for sputum induction for diagnostic purposes [e.g., with an aerosol generator, nebulizer, metered dose inhaler or intermittent positive pressure breathing (IPPB) device]) to dilate the airways. “This means that although the physician performed both test components, you cannot report either component separately spirometry administration of bronchodilator,” adds Pohlig.
Be Careful in Coding Bronchodilator Administration
Case #3: A new asthmatic patient presents in your office with difficulty breathing. The physician administers peak flow to make sure the problem is not serious. The measurement, however, is high, and the physician gives the patient a bronchodilator to open up his airways and takes another peak-flow measurement.
Code this: Because the peak-flow measurement is such a quick and simple test, it is not reimbursable as a standalone test. Code 94060 cannot be used here because a spirometry was not given before and after the bronchodilator; rather, the pulmonologist performed a peak flow. You should report code:
