Bronchitis, not specified as acute or chronic (J40)

Browse all the diagnosis codes used for bronchitis, not specified as acute or chronic (j40). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range.

We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.
