ICD-10 Code J14 – Pneumonia due to Hemophilus influenzae (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J14 – Pneumonia due to Hemophilus influenzae
What it is
J14 identifies pneumonia caused by Haemophilus influenzae. Use it when the record clearly links the lung infection to this organism.
Clinical signs
Typical findings include cough, fever, shortness of breath, and evidence of pneumonia on exam or imaging. Clinical features vary; refer to documentation.
When to use this code
Use J14 when the provider documents pneumonia due to Haemophilus influenzae, or when culture or other accepted testing supports that cause. Code the confirmed infectious etiology rather than a nonspecific pneumonia code when documentation is clear.
If the organism is only suspected, or the note says “possible” or “rule out,” do not assign J14. Check documentation for whether the diagnosis is definitive and whether the pneumonia is community acquired, hospital acquired, or otherwise specified.
Do not use for
Do not use J14 for bronchitis, upper respiratory infection, or pneumonia from another organism. If the cause is not documented as Haemophilus influenzae, check documentation.
Coding tip
Link J14 only to a clearly documented Haemophilus influenzae pneumonia diagnosis, and verify any additional codes needed for associated conditions.
