2007 ICD-9-CM Procedure 95.41 Audiometry Objective tests of middle ear function based on the difficulty (impedance) or ease (admittance) of sound flow through the middle ear. These include static impedance and dynamic impedance (i.e., tympanometry and impedance tests in conjunction with intra-aural muscle reflex elicitation). This term is used also for various components of impedance and admittance (e.g., compliance, conductance, reactance, resistance, susceptance). The testing of the acuity of the sense of hearing to determine the thresholds of the lowest intensity levels at which an individual can hear a set of tones. The frequencies between 125 and 8000 Hz are used to test air conduction thresholds and the frequencies between 250 and 4000 Hz are used to test bone conduction thresholds. 95.41 is a specific code that can be used to specify a procedure 95.41 contains 2 index entries View the full Volume 3 95.* hierarchy 95.41 also known as: Békésy 5-tone audiometry Impedance audiometry Stapedial reflex response Subjective audiometry Tympanogram Index entries containing 95.41: Audiometry (Bekesy 5-tone) (impedance) (stapedial reflex response) (subjective) 95.41 Tympanogram 95.41
