ICD-10 coding for tonsillitis

Tonsillitis can be caused either by virus or bacteria. In either case, complete clinical documentation for tonsillitis needs to include:

  • The cause
  • Time parameter
  • Instructional note indicating tobacco use or exposure to smoking



This is a weekly feature that I use to highlight practical tips on how to use and understand ICD-10-CM/PCS codes. Please let me know of any other sources that I can include.
