Overlap syndrome means you have signs of both asthma and COPD. This is also called Asthma-COPD Overlap Syndrome (ACOS). It can make breathing harder and symptoms more intense. Doctors often use the ICD-10 code J44.9 for this condition. With the right care, many people feel better and breathe easier.
Dr. Chadha explores your breathing issues, smoking and pollution exposures, history of asthma or COPD, frequency and severity of symptoms, and any past lung infections.
This lung function test measures your FEV1 and FVC, and includes bronchodilator reversibility to distinguish asthma-like and COPD-like patterns.
Skin-prick or blood tests identify common asthma triggers such as pollen, dust mites, molds, and pet dander.
Dr. Chadha correlates your clinical history, spirometry, imaging, and allergy results with established asthma-COPD overlap syndrome guidelines to confirm the diagnosis.
