Pneumonia ICD-10 codes
Start with the primary code, then move to a more specific related code when the documentation supports it.
J18.9 | Pneumonia, unspecified organism | ICD-10-CM |
J13 | Pneumonia due to Streptococcus pneumoniae | ICD-10-CM |
J15.9 | Unspecified bacterial pneumonia | ICD-10-CM |
J12.9 | Viral pneumonia, unspecified | ICD-10-CM |
J18.1 | Lobar pneumonia, unspecified organism | ICD-10-CM |
J69.0 | Pneumonitis due to inhalation of food and vomit (aspiration pneumonia) | ICD-10-CM |
Code the organism when cultures or antigen tests identify it — J13 for pneumococcus, J15.- for other bacteria, J12.- for viral. "Community-acquired pneumonia" without an organism is J18.9. A documented aspiration event points to J69.0, which is a different clinical entity, not a J18 variant.
“Productive cough, fever 38.6°C, right-sided pleuritic pain for 2 days. Crackles right base, CRP 156. Chest X-ray: right lower lobe consolidation. CURB-65 = 1. Urinary pneumococcal antigen positive. Amoxicillin started, oral, community management.”
Paste a note or record audio. Notat’s FactsContext™ engine extracts the raw clinical facts first, then suggests codes from that context so you can inspect the evidence before using anything.

FactsContext extracts clinical facts first: diagnoses, symptoms, negatives, findings, test results, medications, and plan decisions.
The clinician can read and reuse the extracted medical context directly, independent of the generated note.
AI suggestions are not a substitute for clinician judgment, payer rules, local coding policy, or the official code set.
FAQ
When can I code better than J18.9?
When the organism is documented — positive culture, PCR, or antigen test. A positive pneumococcal antigen, for example, supports J13 instead of J18.9.
How is aspiration pneumonia coded?
J69.0, pneumonitis due to inhalation of food and vomit. It is not coded from the J12–J18 pneumonia block.
Can AI upgrade my pneumonia coding specificity?
Notat extracts microbiology results and imaging findings as clinical facts, so when the organism is in the note, the organism-specific code is suggested with its evidence.
