J40

Billable

Bronchitis, not specified as acute or chronic

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

Inflammation of the airways in the lungs (bronchitis) without clear indication of whether it is acute or chronic in nature.

Coding Tips

  • Query the provider to determine if bronchitis is acute or chronic, as more specific codes (J20 for acute, J41-J42 for chronic) are preferred
  • Document the duration and characteristics of symptoms to support acute versus chronic classification

  • acute bronchitis (J20.-)
  • allergic bronchitis NOS (J45.909)
  • asthmatic bronchitis NOS (J45.9-)
  • bronchitis due to chemicals, gases, fumes and vapors (J68.0)
