ICD-10 Code A69 – Other spirochetal infections (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A69 – Other spirochetal infections
What it is
Code A69 covers infections caused by spirochetes that are not classified elsewhere. Use it for documented spirochetal disease when the record does not identify a more specific code.
Clinical signs
Clinical features vary; refer to documentation. Findings may include signs of systemic infection or localized disease caused by a spirochete, but the exact presentation depends on the organism involved.
When to use this code
Use A69 when the provider documents an other spirochetal infection and no more specific ICD-10-CM code applies. It is appropriate when the organism is identified as spirochetal but not further classified in the note. If the record names a specific disease, code that diagnosis instead.
Do not use for
Do not use this code for spirochetal infections with a more specific ICD-10-CM category, such as a named condition elsewhere in the classification. Check documentation if the organism or diagnosis is unclear.
Coding tip
Review the provider’s exact wording and code the most specific documented spirochetal infection available.
