Answer: Lisa Villella, office manager for Peachtree Pediatrics, a two-pediatrician practice in Peachtree City, GA, says to use the basic asthma code: 493.0. This is for extrinsic asthma: transient narrowing of airway diameters in the bronchial tree, caused by environmental factor. Included is allergic asthma, atopic asthma, and childhood asthma.
Tip: Asthma codes need a fifth digit. The fifth digit 0" is without mention of status asthmaticus, and 1" is with status asthmaticus.
