Non-billable headerNot valid on its own. Use one of the more specific codes under it.

J15 is a non-billable ICD-10-CM code category for bacterial pneumonia, not elsewhere classified. Report a more specific code from it instead. It is part of the FY2027 code set, effective October 1, 2026. The more specific codes under it are J15.0 Pneumonia due to Klebsiella pneumoniae; J15.1 Pneumonia due to Pseudomonas; J15.2 Pneumonia due to staphylococcus; J15.3 Pneumonia due to streptococcus, group B and 6 more. Its coding notes include a Code first instruction, a Use additional code instruction, a Code also instruction, 4 Excludes1 entries and 18 Excludes2 entries.

Notes

Also from chapter/block level (1 note)
Inherited from Chapter 10 Diseases of the respiratory system
  • When a respiratory condition is described as occurring in more than one site and is not specifically indexed, it should be classified to the lower anatomic site (e.g. tracheobronchitis to bronchitis in J40).
