ICD-10 code for cold
From the official ICD-10-CM alphabetic index entry “Cold”. Page updated September 29, 2026.
About coding cold
The ICD-10-CM code for cold is J00 (Acute nasopharyngitis [common cold]). The official index lists 15 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on J00.
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.
