A49.8 ICD-10-CM Code: Other bacterial infections of unspecified site

A49.8 is the ICD-10-CM diagnosis code for other bacterial infections of unspecified site. This code is used when a patient has a bacterial infection at an unspecified location in the body that doesn't fit into other more specific bacterial infection categories. It's a catch-all code for bacterial infections where the exact site or type cannot be determined or documented. A49.8 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering other bacterial diseases (a30-a49).

A49.8 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.

Only use this code when the specific site of infection cannot be identified or documented; always attempt to obtain more specific information about the infection location from the provider.
