Viral pneumonia, not elsewhere classified (J12) ICD-10-CM
The J12 code range covers viral pneumonia, not elsewhere classified with 10 ICD-10-CM diagnosis codes. 8 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- bronchopneumonia due to viruses other than influenza viruses
Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
Code Also
A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.
- associated abscess, if applicable J85.1
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the J12 range.
Pneumonia, Viral
Inflammation of the lung parenchyma that is caused by a viral infection.
Respiratory Syncytial Virus Pneumonia
Pneumonia that is attributed to the respiratory syncytial virus.
About the J12 Code Range
Viral pneumonia is inflammation of lung tissue caused by a virus. This category separates pneumonia by the virus named in the diagnosis.
J12.0, J12.1, J12.2, and J12.3 identify adenovirus, respiratory syncytial virus, parainfluenza virus, and human metapneumovirus. Under other viral pneumonia, J12.8, the codes distinguish SARS-associated coronavirus, coronavirus disease, and other viral pneumonia. J12.9 is viral pneumonia with no virus specified.
