R05 — Cough

Non-billable headerICD-10-CM

R05 is a non-billable header ICD-10-CM code for cough. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

paroxysmal cough due to Bordetella pertussis (A37.0-)
smoker's cough (J41.0)

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

cough with hemorrhage (R04.2)

Risk adjustment

R05 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead R05

6 child codes. Green means billable.
