In simple words: This code covers a special type of hearing aid for people who can't hear well in one ear but have normal hearing in the other. It involves a small device worn in the ear with good hearing, connected wirelessly to a microphone on the deaf side. This helps the person hear sounds from the deaf side through their good ear.

This code represents a monaural (one-sided) in-the-canal (ITC) hearing aid with contralateral routing.It is typically used for patients with single-sided deafness, where one ear has hearing loss and the other has normal or near-normal hearing. The device is worn in the better-hearing ear, and a microphone is placed on the side with hearing loss. This setup allows sound to be picked up by the microphone on the impaired side and transmitted to the hearing aid in the better-hearing ear.

Example 1: A patient with single-sided deafness due to a childhood infection is fitted with a contralateral routing ITC hearing aid., A patient with an acoustic neuroma resulting in hearing loss in one ear is provided with a V5172 device., An individual with normal hearing in one ear and hearing loss in the other due to noise exposure is fitted with a contralateral routing hearing aid to improve their ability to localize sounds.

Documentation should include the type of hearing loss, the results of a hearing evaluation, the rationale for selecting a contralateral routing device, and the specific model of the device provided.
