J41.0 — Simple chronic bronchitis
J41.0 is a billable, specific ICD-10-CM code for simple chronic bronchitis. It is valid for submission on a claim.
Excludes2 inherited from the categories above J41.0
Also inherited, and the opposite of Excludes1: these conditions are not part of J41.0, but a patient can have both, so you may code both.
Other codes that can never be billed with J41.0
These codes carry an Excludes1 note pointing at J41.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading J41.0 alone.
Risk adjustment
J41.0 risk-adjusts. Under the CMS-HCC V28 model it maps to this category:
- HCC 280 Chronic Obstructive Pulmonary Disease, Interstitial Lung Disorders, and Other Chronic Lung Disorders0.319 RAF
Coefficient shown for the Community Non-dual Aged segment. A higher HCC in the same hierarchy will suppress this one, so capturing it does not always add score.
Medicare coverage
J41.0 is named in 20 Medicare coverage policies — 18 listing it as supporting medical necessity, and 2 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
