R06.2: Wheezing

Wheezing, as classified by ICD-10 under code R06.2, is a specific respiratory symptom characterized by a high-pitched whistling sound that is heard primarily during exhalation (breathing out). This sound is caused by the narrowing or obstruction of airways, the tubes that carry air into and out of the lungs. Common conditions that can lead to wheezing include asthma, allergies, lung disease, and certain infections. While the specific cause can vary, the presence of wheezing generally indicates difficulty moving air through the bronchial tubes. Depending on the underlying issue, wheezing can be accompanied by other symptoms such as shortness of breath, coughing, or chest tightness. Additionally, the severity and frequency of wheezing will typically be determined by the severity of the underlying condition or trigger causing respiratory distress.
