ICD-10 Code A21.2 – Pulmonary tularemia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A21.2 – Pulmonary tularemia
What it is
A21.2 identifies tularemia infection involving the lungs. Use it when Francisella tularensis disease is documented as pulmonary or pneumonic.
Clinical signs
Clinical features vary; refer to documentation. Pulmonary involvement may present with cough, chest pain, shortness of breath, or pneumonia-like findings, often after exposure history supports tularemia.
When to use this code
Use A21.2 when the provider documents pulmonary tularemia, pneumonic tularemia, or tularemic pneumonia. It is appropriate when the lung is the primary site of infection, even if other tularemia manifestations are also noted.
If the record only says tularemia without site, check documentation for the specific form before coding.
Do not use for
Do not use this code for nonspecific pneumonia without documented tularemia. Also avoid it when the infection is cutaneous, oculoglandular, or another nonpulmonary form.
Coding tip
Confirm the provider links tularemia to the lungs; if the anatomic site is not clear, query or check documentation.
