What This Code Means

A69.29 is the ICD-10-CM diagnosis code for other conditions associated with lyme disease. This code is used for various complications and conditions that develop as a result of Lyme disease infection, beyond the more common manifestations like joint pain or facial paralysis. It captures the broader systemic effects that can occur when the Lyme disease infection affects different parts of the body. A69.29 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering other spirochetal diseases (a65-a69).

A69.29 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.

Use this code only after confirming the condition is directly associated with Lyme disease; do not use for unrelated conditions that happen to occur in a patient with Lyme disease history.

HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for A69.29 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips
