About the J96–J99 Code Range
ICD-10 codes J96 to J99 are used to classify a variety of respiratory system diseases that do not fit into common categories like infections or asthma. This range primarily covers different forms of respiratory failure, other lung and bronchial disorders, mediastinal conditions, and respiratory problems linked to other diseases.
The codes from J96 specify states of respiratory failure, including acute, chronic, and acute-on-chronic respiratory failure, with distinctions based on presence of hypoxia (low oxygen) or hypercapnia (high carbon dioxide). For example, conditions like hypoxemic respiratory failure or hypercapnic respiratory failure correspond to codes such as J96.01 and J96.02. J98 covers other respiratory disorders affecting the bronchus, lungs, diaphragm, and mediastinum, including acute bronchospasm (J98.01), atelectasis or pulmonary collapse (J98.11), and various lung conditions like restrictive lung disease and pulmonary fibrosis variant syndromes (J98.4). This range also flags complications such as mediastinitis (J98.51) and diaphragm disorders like paralysis or displacement (J98.6). Lastly, J99 identifies respiratory disorders that occur in the course of other systemic diseases, for instance, lung involvement in connective tissue diseases or pulmonary histoplasmosis. These codes help medical coders accurately capture complex respiratory diagnoses for clinical documentation and billing, ensuring nuanced respiratory conditions are properly recorded and recognized.
Questions About This Page
How many codes are in the J96-J99 range?
The J96-J99 range contains 34 ICD-10-CM diagnosis codes in FY 2026. 25 of them are billable, and the rest are category headers that organize the section.
What conditions does J96-J99 cover?
The range covers other diseases of the respiratory system. 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.
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.
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.
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.
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
