CodeDescriptionWhen to UseKey Documentation
J35.1Hypertrophy of tonsilsUse when tonsillar hypertrophy is present without active inflammation or infection.
  • Clinical examination showing enlarged tonsils without signs of infection
  • Imaging studies indicating airway obstruction

Mitigation Strategy

Use J35.0 if tonsillitis is present.

Impact

Lack of specific documentation for hypertrophy can lead to audit issues.
