Nitric oxide expired gas determination.
Modifiers such as 25 (Significant Separately Identifiable E/M Service), 52 (Reduced Services), 53 (Discontinued Procedure), 76 (Repeat Procedure by Same Physician), 79 (Unrelated Procedure by Same Physician During Postoperative Period), 80, 81, 82 (Assistant Surgeon), and 99 (Multiple Modifiers) may be applicable depending on the specific circumstances.
Medical necessity for this test is established by the presence of signs, symptoms, or conditions that suggest airway inflammation, such as asthma, or the need to monitor the effectiveness of anti-inflammatory therapy.
The provider instructs the patient to inhale nitric oxide-free air to maximum inhalation capacity and exhale into a nitric oxide monitoring system. The provider measures the amount of exhaled nitric oxide. This test is performed before and after starting anti-inflammatory treatment for suspected or confirmed airway inflammation, aiding in treatment assessment and asthma management. The results guide adjustments in anti-inflammatory treatment dosage.
In simple words: This is a simple breathing test that measures the amount of nitric oxide in your breath. Nitric oxide is a gas that's associated with inflammation in the airways. The test helps doctors check for and monitor lung conditions like asthma.
This test measures the amount of nitric oxide in exhaled breath, which is an indicator of airway inflammation. The patient inhales nitric oxide-free air to maximum capacity and then exhales into a monitoring system. This procedure is used to assess the level of inflammation in patients with suspected or confirmed airway inflammatory diseases like asthma, and to monitor their response to anti-inflammatory treatment.
Example 1: A patient with suspected asthma undergoes the nitric oxide expired gas determination test to assess the level of airway inflammation and aid in diagnosis., A patient with diagnosed asthma who has started anti-inflammatory medication undergoes the test to monitor their response to the treatment and guide dose adjustment., A patient experiences worsening asthma symptoms despite treatment. The nitric oxide test helps evaluate the current level of airway inflammation and inform potential treatment modifications.
Documentation should include the reason for testing, the test results in parts per billion (ppb), and how the results influenced treatment decisions.
