Voice Box Exam With Stretching Of A Narrowing

South Dakota rates for HCPCS 31528

A scope is passed through the mouth into the voice box so the surgeon can look at it directly and widen a narrowed part of the airway, stretching it with a dilator or a balloon. It relieves noisy or difficult breathing and a weak voice caused by scarring or narrowing. This covers the first such stretching; repeat sessions are billed separately.
