Hearing impaired
- G1Adult: Subjective change in hearing in the absence of documented hearing loss; threshold shift of 15 - 25 dB averaged at 2 contiguous test frequencies in at least one ear (on a 1, 2, 4, 3, 6, and 8 kHz audiogram); Pediatric (on a 1, 2, 3, 4, 6, and 8 kHz audiogram): Threshold shift >20 dB hearing loss (HL) (i.e., 25 dB HL or greater); sensorineural hearing loss (SNHL) above 4 kHz (i.e., 6 or 8 kHz) in at least one ear
- G2Adult: Hearing loss not requiring hearing aid; intervention not indicated; limiting instrumental ADL; threshold shift of >25 dB averaged at 2 contiguous test frequencies in at least one ear (on a 1, 2, 3, 4, 6, and 8 kHz audiogram); Pediatric (on a 1, 2, 3, 4, 6, and 8 kHz audiogram): Threshold shift >20 dB at 4 kHz in at least one ear; mild/moderate impact on age-appropriate normal daily activity
- G3Adult: Hearing loss requiring hearing aid; intervention indicated; limiting self-care ADL; threshold shift of >25 dB averaged at 3 contiguous test frequencies in at least one ear(on a 1, 2, 3, 4, 6, and 8 kHz audiogram); Pediatric (on a 1, 2, 3, 4, 6, and 8 kHz audiogram): Hearing loss sufficient to indicate therapeutic intervention, including hearing aids; threshold shift >20 dB at 2 to <4 kHz in at least one ear; severe impact on age-appropriate normal daily activity
- G4Adult: Nonservicable hearing; decrease in hearing to profound bilateral loss (absolute threshold >80 dB HL at 2 kHz and above); Pediatric: Audiologic indication for cochlear implant; >40 dB HL (i.e., 45 dB HL or more); SNHL at 2 kHz and above
- G5Not applicable
