Other respiratory disorders (J98) ICD-10-CM

The J98 code range covers other respiratory disorders with 16 ICD-10-CM diagnosis codes. 12 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.

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.

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.

Type 2 Excludes

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.

Clinical Terms in This Code Range

Definitions from the National Library of Medicine for conditions coded in the J98 range.

Bronchial Spasm

Spasmodic contraction of the smooth muscle of the bronchi.

Bronchomalacia

A congenital or acquired condition of underdeveloped or degeneration of CARTILAGE in the BRONCHI. This results in a floppy bronchial wall making patency difficult to maintain. It is characterized by wheezing and difficult breathing.

Mediastinal Emphysema

Presence of air in the mediastinal tissues due to leakage of air from the tracheobronchial tree, usually as a result of trauma.

Mediastinitis

Inflammation of the mediastinum, the area between the pleural sacs.

Middle Lobe Syndrome

Atelectasis of the right middle pulmonary lobe, with chronic pneumonitis. (Dorland, 27th ed)

Pulmonary Atelectasis

Absence of air in the entire or part of a lung, such as an incompletely inflated neonate lung or a collapsed adult lung. Pulmonary atelectasis can be caused by airway obstruction, lung compression, fibrotic contraction, or other factors.

Respiratory System Disorder

A non-neoplastic or neoplastic disorder that affects the respiratory system. Representative examples include pneumonia, chronic obstructive pulmonary disease, pulmonary failure, lung adenoma, lung carcinoma, and tracheal carcinoma.

About the J98 Code Range

These disorders affect an airway called the bronchus, the lungs, the space between the lungs called the mediastinum, or the diaphragm.

J98.0 separates acute bronchospasm from other bronchial diseases. J98.1 separates atelectasis, a type of lung collapse, from other lung collapse. Separate entries distinguish interstitial emphysema from compensatory emphysema. J98.4 identifies other lung disorders.

J98.5 separates mediastinitis from other diseases of the mediastinum. The remaining entries identify diaphragm disorders, other specified respiratory disorders, and an unspecified respiratory disorder.

Questions About This Page

How many billable codes are in the J98 range?

Of the 16 codes in this range, 12 are billable and valid for claim submission from October 1, 2026 through September 30, 2027. Category header codes group them but cannot be reported on claims.

What does the J98 range classify?

The range classifies other respiratory disorders. Each code links to its own reference page with billing status, MS-DRG grouping, coding notes, and clinical information.
