Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

About the J00–J06 Code Range
ICD-10 codes J00-J06 cover a variety of acute upper respiratory infections affecting the nose, sinuses, throat, larynx, and trachea. These codes are used to classify sudden infections like the common cold, different types of sinusitis, pharyngitis, tonsillitis, laryngitis, croup, and epiglottitis.
This range starts with J00, for acute nasopharyngitis, commonly known as the common cold, which also includes terms like acute irritant rhinitis and parainfluenza virus rhinopharyngitis. Codes from J01 to J01.91 specify various forms of acute sinusitis, including maxillary, frontal, ethmoidal, sphenoidal, pansinusitis, and their recurrent or unspecified types. The J02 series focuses on acute pharyngitis, including streptococcal and viral causes. The J03 codes cover acute tonsillitis, detailing streptococcal and other bacterial infections, plus recurrent forms. The group J04 relates to acute laryngitis, tracheitis, and laryngotracheitis, highlighting both viral and bacterial causes with or without airway obstruction. J05 encompasses acute obstructive laryngitis, commonly called croup, and epiglottitis, with attention to the presence of airway obstruction. Finally, J06 covers infections affecting multiple or unspecified upper respiratory sites, including acute laryngopharyngitis and unspecified acute upper respiratory infections. These codes assist healthcare professionals in precisely identifying and documenting specific acute infections of the upper respiratory tract during diagnosis and treatment.
Questions About This Page
How many codes are in the J00-J06 range?
The J00-J06 range contains 54 ICD-10-CM diagnosis codes in FY 2026. 35 of them are billable, and the rest are category headers that organize the section.
What conditions does J00-J06 cover?
The range covers acute upper respiratory infections. The code ranges listed above break it into groups of related conditions, and each one links to its own page with the full code list.
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.

acute empyema of sinus
acute infection of sinus

Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
