About coding common head cold

The ICD-10-CM code for common head cold is J00 (Acute nasopharyngitis [common cold]).

Don't report J00 together with the conditions in its Excludes1 note: acute pharyngitis (J02.-), acute sore throat NOS (J02.9), influenza virus with other respiratory manifestations (J09.X2, J10.1, J11.1), pharyngitis NOS (J02.9) and 2 more.

The conditions in its Excludes2 note aren't part of J00, but may be coded alongside it if the patient has both: allergic rhinitis (J30.1-J30.9), chronic pharyngitis (J31.2), chronic rhinitis (J31.0), chronic sore throat (J31.2) and 2 more.

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

Don't confuse with (Excludes1 for J00)

  • acute pharyngitis (J02.-)
  • acute sore throat NOS (J02.9)
  • influenza virus with other respiratory manifestations (J09.X2, J10.1, J11.1)
  • pharyngitis NOS (J02.9)
  • rhinitis NOS (J31.0)
  • sore throat NOS (J02.9)
