What This Code Means
A69.8 is the ICD-10-CM diagnosis code for other specified spirochetal infections. This code is used for spirochetal infections (infections caused by spiral-shaped bacteria) that don't fit into other specific categories. These are uncommon bacterial infections that require documentation of the specific organism or infection type. A69.8 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering other spirochetal diseases (a65-a69).
A69.8 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Always review the medical record for specific organism identification or infection site, as this code should only be used when the spirochetal infection doesn't meet criteria for more specific codes like leptospirosis (A27) or relapsing fever (A68).
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for A69.8 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Always review the medical record for specific organism identification or infection site, as this code should only be used when the spirochetal infection doesn't meet criteria for more specific codes like leptospirosis (A27) or relapsing fever (A68)
- •Ensure the documentation clearly indicates a spirochetal infection and consider querying the provider if the specific type of infection is unclear, as more specific coding may be appropriate
