Cough (R05) ICD-10-CM
The R05 code range covers cough with 7 ICD-10-CM diagnosis codes. 6 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
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.

Chronic Cough
Cough lasting for greater than 8 weeks in adults potentially impacting HEALTH-RELATED QUALITY OF LIFE. Chronic cough generally is associated with eosinophilic airway inflammation (e.g., asthma (COUGH-VARIANT ASTHMA) and non-asthmatic BRONCHITIS, upper airway disorders, GERD and cough hypersensitivity syndrome).
Cough
A sudden, audible expulsion of air from the lungs through a partially closed glottis, preceded by inhalation. It is a protective response that serves to clear the trachea, bronchi, and/or lungs of irritants and secretions, or to prevent aspiration of foreign materials into the lungs.
