ASHA Notes

  • For confirmed active cases of COVID-19, use U07.1.
    • Code the associated speech, language, cognitive, voice, or swallowing disorder secondary to U07.1 when the disorder is directly caused by, but is not inherent to, COVID-19.
    • Don’t separately code respiratory conditions (e.g., cough) because they’re inherent to COVID-19, a primarily respiratory illness.
  • 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., dysphagia).
    • 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 speech, language, cognitive, voice, or swallowing 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 speech, language, congitive, voice, or swallowing disorder is directly caused by COVID-19.
    • There is no time limit on when personal history or sequelae codes may be used.
