What diagnosis do you use if the doctor wants comprehensive hearing tests and tympanometry to rule out a disease and the tests results comeback within normal limits? My research shows V72.19. Is that good to use as a primary code for these tests? Also, if a patient comes in and takes the hearing survey and "thinks" they have hearing loss, but the actual test results are within normal limits, can I use 388.40, Impaired auditory perception? I would like to know your thoughts and opinions. Thanks!
