ICD-10 Code B38.2 – Pulmonary coccidioidomycosis, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B38.2 – Pulmonary coccidioidomycosis, unspecified
What it is
B38.2 identifies coccidioidomycosis involving the lungs when the record does not specify a more exact pulmonary form. Use it for documented pulmonary infection due to Coccidioides, often called Valley fever.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include cough, fever, chest pain, fatigue, or abnormal chest imaging, but the chart should support pulmonary involvement.
When to use this code
Use this code when the provider documents pulmonary coccidioidomycosis without naming a specific pulmonary complication or subtype. It also fits cases where the infection is confirmed in the lungs but details remain unspecified. If the record identifies another form, code that more specific diagnosis instead.
Do not use for
Do not use B38.2 for extrapulmonary coccidioidomycosis or for nonspecific fungal pneumonia without documented Coccidioides infection. Check documentation if the site, organism, or pulmonary manifestation is not clearly stated.
Coding tip
Assign the most specific coccidioidomycosis code available; if the lungs are involved but the type is not further described, B38.2 is appropriate.
