J17
Billable codePneumonia in diseases classified elsewhere
The ICD-10 code for pneumonia in diseases classified elsewhere is J17.
Clinical notes
Code also
Two codes may be needed to fully describe a condition, but unlike Code First/Use Additional Code, the sequencing order is not mandated by convention.
Code first
This code represents a manifestation of an underlying disease. Coding convention requires the underlying (etiology) code to be sequenced first, with this code listed second.
Excludes1 (not coded here)
An Excludes1 note is a pure exclusion: the excluded condition and this code should never be reported together, because the two conditions cannot occur at the same time (e.g. a congenital form vs. an acquired form of the same disease).
- candidial pneumonia (B37.1)
- chlamydial pneumonia (J16.0)
- gonorrheal pneumonia (A54.84)
- histoplasmosis pneumonia (B39.0-B39.2)
- measles pneumonia (B05.2)
- nocardiosis pneumonia (A43.0)
- pneumocystosis (B59)
- pneumonia due to Pneumocystis carinii (B59)
- pneumonia due to Pneumocystis jirovecii (B59)
- pneumonia in actinomycosis (A42.0)
- pneumonia in anthrax (A22.1)
- pneumonia in ascariasis (B77.81)
- pneumonia in aspergillosis (B44.0-B44.1)
- pneumonia in coccidioidomycosis (B38.0-B38.2)
- pneumonia in cytomegalovirus disease (B25.0)
- pneumonia in toxoplasmosis (B58.3)
- rubella pneumonia (B06.81)
- salmonella pneumonia (A02.22)
- spirochetal infection NEC with pneumonia (A69.8)
- tularemia pneumonia (A21.2)
- typhoid fever with pneumonia (A01.03)
- varicella pneumonia (B01.2)
- whooping cough with pneumonia (A37 with fifth-character 1)
Documentation support
General coding-documentation guidance — not a substitute for payer-specific requirements or professional coding judgment.
- •Confirm the excluded condition(s) listed above are not also present — Excludes1 conditions cannot be coded together with this one.
- •This code represents a manifestation. Documentation should identify the underlying condition, which must be coded first.
- •As a general rule, code to the highest level of specificity supported by the documentation in the medical record.
