J41

J41 — Simple and mucopurulent chronic bronchitis

Non-billable headerICD-10-CM

J41 is a non-billable header ICD-10-CM code for simple and mucopurulent chronic bronchitis. It cannot be billed on its own: choose one of the more specific child codes below.

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.

chronic bronchitis NOS (J42)
chronic obstructive bronchitis (J44.-)

Use additional code

Add a secondary code to capture the detail described below.

code to identify:
exposure to environmental tobacco smoke (Z77.22)
exposure to tobacco smoke in the perinatal period (P96.81)
history of tobacco dependence (Z87.891)
occupational exposure to environmental tobacco smoke (Z57.31)
tobacco dependence (F17.-)
tobacco use (Z72.0)

Other codes that can never be billed with J41

These codes carry an Excludes1 note pointing at J41. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading J41 alone.

J42Unspecified chronic bronchitis

Risk adjustment

J41 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 J41

3 child codes. Green means billable.
