ICD-10 Code A69.8 – Other specified spirochetal infections (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A69.8 – Other specified spirochetal infections
What it is
A69.8 identifies a spirochetal infection that is documented but does not fit a more specific ICD-10 category. Use it for confirmed or clinically specified spirochetal disease when the exact organism or named syndrome is not separately coded.
Clinical signs
Clinical features vary; refer to documentation. Signs may reflect a spirochetal infection such as compatible systemic or localized findings, but the record should support the specific infection being described.
When to use this code
Use A69.8 when the provider documents an “other specified” spirochetal infection and no more specific code applies. It is appropriate when the organism or syndrome is named, but ICD-10 does not offer a better match. Check documentation for the exact diagnosis wording and site, if stated.
Do not use for
Do not use this code for unspecified spirochetal infection or for conditions that have their own specific ICD-10 code. Do not guess the diagnosis when the chart lacks clear documentation.
Coding tip
Match the code to the provider’s exact wording and confirm that no more specific spirochetal infection code is available.
