The following new and revised ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification) codes were effective October 1, 2020, for fiscal year (FY) 2021. ICD-10-CM codes are updated annually. For current updates, see audiology ICD-10-CM code changes for FY 2023.

There were no major changes to ICD-10 codes related to audiology for FY 2021. However, audiologists should be aware of new ICD-10 codes related to COVID-19, which were published off-cycle in 2020 and 2021. Vestibular audiologists should also be aware of two new and revised codes related to eye movements.

ASHA Notes

  • For confirmed active cases of COVID-19, use U07.1.
    • Code the associated hearing or vestibular disorder secondary to U07.1 when the disorder is directly caused by, but is not inherent to, COVID-19.
  • For suspected cases of COVID-19, use Z20.822 and/or the presenting signs and symptoms.
  • For resolved cases of COVID-19 use Z86.16 or B94.8 (sequelae of other specified infectious and parasitic diseases), secondary to the treating ICD-10-CM code(s) (e.g., hearing loss).
    • Z86.16 describes patients with a confirmed case of COVID-19 but who are no longer infected (resolved COVID-19). Use this code when COVID-19 is a factor in the reason for the visit, but is not the direct cause of the hearing or vestibular disorder.
    • B94.8 is not a new code but is also used for patients with resolved COVID-19. Use this code when there is clear documentation that the hearing or vestibular disorder is directly caused by COVID-19. (Note: This guidance has changed. Please see FY 2022 updates for current information.)
    • There is no time limit on when personal history or sequelae codes may be used.
