ICD-10 Code A95.9 – Yellow fever, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A95.9 – Yellow fever, unspecified
What it is
A95.9 identifies yellow fever when the record does not specify the type or phase. Use it for a confirmed diagnosis of yellow fever without added detail.
Clinical signs
Clinical features vary; refer to documentation. Yellow fever is typically an acute febrile illness, and severe cases may include jaundice, bleeding, or organ involvement.
When to use this code
Use A95.9 when the clinician documents yellow fever but does not name a specific variant, stage, or complication. It also fits when the chart confirms the infection, yet details are incomplete. You should code the documented diagnosis, not assumptions.
Do not use for
Do not use this code for suspected yellow fever without confirmation, or for a more specific yellow fever code if the record provides one. Check documentation when the diagnosis is unclear.
Coding tip
Confirm that the provider documented yellow fever explicitly before assigning A95.9.
