Repeat Stretching of the Voice Box Airway

Washington, DC rates for HCPCS 31529

A scope is passed into the voice box, and the windpipe below it when needed, and a narrowed section of the airway is stretched open with a balloon or dilator. It is used when scarring or swelling has tightened the airway, causing noisy or difficult breathing or a weak voice. This is a repeat stretching, carried out after an earlier one.
