ICD-10 Code B38.8 – Other forms of coccidioidomycosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B38.8 – Other forms of coccidioidomycosis
What it is
B38.8 identifies coccidioidomycosis presentations that do not fit the more specific ICD-10-CM subcategories. Use it for confirmed Valley fever manifestations when the record describes another form, but not a named site or complication.
Clinical signs
Clinical features vary; refer to documentation. Patients may have fever, cough, chest pain, fatigue, or other organ involvement consistent with coccidioidal infection, but you should code only what is documented.
When to use this code
Use B38.8 when the provider documents coccidioidomycosis and specifies an “other” form, or when the infection is confirmed but does not match a more specific code. It may apply to unusual presentations not captured elsewhere in category B38. Check documentation for the exact site or manifestation.
Do not use for
Do not use this code for unspecified coccidioidomycosis if the record supports a more specific category. Also avoid it when the condition is only suspected, ruled out, or better described by another infectious diagnosis.
Coding tip
Always look for the provider’s exact wording and any documented site or complication before selecting B38.8.
