Non-Billable HeaderCough
About ICD-10-CM R05
ICD-10-CM code R05 represents Cough. This is a non-billable header code in the Symptoms, Signs, and Abnormal Findings chapter (block R05). The 2026 edition of ICD-10-CM R05 became effective on October 1, 2025. Non-billable codes cannot be used as a primary or secondary diagnosis on a claim, use a more specific child code instead.
Type 1 Excludes
Pure excludes, these codes can never be coded together with R05. The conditions are mutually exclusive (e.g., congenital vs acquired forms).
- paroxysmal cough due to Bordetella pertussis (A37.0-)
- smoker's cough (J41.0)
Type 2 Excludes
Not included here, the excluded code is not part of R05, but a patient may have both conditions at the same time. Both codes may be coded together when applicable.
- cough with hemorrhage (R04.2)
