CPT® Code 69705

Balloon dilation of the Eustachian tube(s) is a surgical procedure performed endoscopically through the nasal passage. This technique utilizes a balloon catheter that is inserted into the Eustachian tube, which connects the middle ear to the nasopharynx. The primary purpose of this procedure is to improve the patency of the Eustachian tube and alleviate chronic ear congestion that may arise from conditions such as middle ear infections or mastoid infections. The Eustachian tube plays a crucial role in equalizing pressure and ventilating the ear, as it opens during actions like swallowing or yawning. During the procedure, a saline-filled balloon catheter is carefully introduced into the Eustachian tube using an endoscope, which is a specialized instrument designed for this purpose. Once the balloon is correctly positioned, it is inflated to maintain pressure for a few minutes, effectively stretching and opening the tube. After sufficient dilation, the balloon is deflated and removed, followed by the withdrawal of the endoscope and catheter. This procedure is typically conducted under general anesthesia to ensure patient comfort. For billing purposes, CPT® Code 69705 is used to report the dilation of one Eustachian tube, while CPT® Code 69706 is designated for the dilation of both tubes.
