About the J00–J06 Code Range
These acute infections affect the upper respiratory tract. The categories separate the common cold from conditions involving the sinuses, throat, tonsils, voice box, or windpipe.
J00 is the common cold. J01 separates acute sinusitis by named sinus site, with entries for pansinusitis and other or unspecified cases. J02 covers pharyngitis, or throat inflammation, while J03 covers tonsillitis, or tonsil inflammation. Both distinguish streptococcal, other specified, and unspecified cases.
J04 separates laryngitis and tracheitis, affecting the voice box and windpipe, from combined or other named conditions. J05 separates croup from epiglottitis. J06 covers infections of multiple or unspecified upper respiratory sites.
