Bronchial Thermoplasty for Severe Asthma

California rates for HCPCS 31660

A thin scope is passed through the mouth or nose into the airways, and controlled heat is applied to the airway walls to reduce the muscle that makes them tighten. It is used for severe asthma that stays poorly controlled despite medication, and the treatment is spread over more than one session. Sedation is given so the procedure is comfortable.
