Hearing thresholds in the high pitches fall into the severe degree of hearing loss, as the threshold at 2000 Hz is 40 dB, 65 dB at 4000 Hz and 75 dB at 8000 Hz. In the right ear, this person has normal hearing in the lower pitches indicated by a red circle corresponding to 15 dB at 250 Hz and 20 dB at 500 Hz. In the audiogram below, hearing thresholds for the right ear are represented by red circles and thresholds for the left ear are represented by the blue X. Understanding the information shown on an audiogram is easy. Sound level, in dB, is plotted on the left side of the graph and ranges from very faint sounds (-10 dB) at the top to very intense sounds (120 dB) at the bottom. Frequency is plotted at the top of the graph, ranging from low frequencies(250 Hz) on the left to high frequencies (8000 Hz) on the right. The graph to the left represents a blank audiogram illustrates the degrees of hearing loss listed above. 92630 Auditory rehabilitation Prelingual hearing loss (i.e.) auditory training therapy for those whose hearing loss was acquired before language. The list below outlines different hearing loss thresholds as they are determined in relation to an individual with a normal hearing threshold. For example, persons with mild hearing loss have thresholds that are 25 to 40 dB higher than the thresholds for those with normal hearing when tested using different at several frequencies. Audiologists have special training in the prevention, diagnosis and non-medical treatment of hearing disorders. The degree of hearing loss is expressed by the difference between a person’s threshold and the average threshold for people with normal sensitivity. During a diagnostic hearing evaluation the threshold is measured at different frequencies (or Hertz, Hz) in each ear. The decibel (or dB) is the unit of intensity used to describe hearing sensitivity. For claims with a date of service on or after October 1, 2015, use an equivalent ICD-10. ICD-9-CM 389.18 is a billable medical code that can be used to indicate a diagnosis on a reimbursement claim, however, 389.18 should only be used for claims with a date of service on or before September 30, 2015. Hearing Aids /FM Systems (HCPCS Level II Codes) Assessment for hearing aid. Hearing thresholds are defined as the lowest level sound that can be heard 50% of the time. Short description: Sensonrl hear loss,bilat. comprehensive diagnostic evaluation (quantitative analysis of outer hair cell function by cochlear mapping, minimum of 12 frequencies), with interpretation and report. In order to determine a person’s degree of hearing loss, their hearing thresholds must be determined. The amount (or degree) of hearing loss a person experiences is based on hearing sensitivity. Hearing loss in the better ear of 30 dBHL or greater (re - ANSI 1969) for the pure tone average of 500, 10Hz ii. What information is on an audiogram and what does it mean for the person’s hearing ability? statement (psychosocial assessment) that the member is alert, oriented and able to utilize their aid appropriately i.
