H90.0: Conductive hearing loss, bilateral
You can hear little or nothing in both ears.
The ear consists of 3 sections: the outer ear, the middle ear, and the inner ear. Noise or sound from the world around us reach our ear as sound waves. These sound waves first go to the eardrum via the outer auditory canal. The sound waves make the eardrum vibrate. The ossicles pass this vibration on to the inner ear. Once passed on, the inner ear and the brain process the vibrations in such a way that we can hear.
You are hearing little or nothing in your ear because the sound waves are not being passed on properly. There are many reasons for this. For example, the outer auditory canal may be blocked by earwax. Sound waves cannot be transmitted properly, either, if the middle ear is inflamed.
On medical documents, the ICD code is often appended by letters that indicate the diagnostic certainty or the affected side of the body.
- G: Confirmed diagnosis
- V: Tentative diagnosis
