B96.89 has no V28 reference coefficient because the final FY2026 source verifies no payable V28 mapping.

What is the V28 vs V24 difference for B96.89?

B96.89 has verified no payable V28 mapping in the final FY2026 source. Select a historical effective period before making any V24 comparison.

What documentation supports B96.89?

Use when a specific bacterial organism is identified but does not fit into other B96 subcategories Always pair with a primary diagnosis code indicating the type of infection or disease B96.89 is not a CMS-HCC V28 payment code in the verified current source, so MEAT is not the payment hook. Documentation still has to support the diagnosis if you report it.

What This Code Means

B96.89 is the ICD-10-CM diagnosis code for other specified bacterial agents as the cause of diseases classified elsewhere. This code represents other specified bacteria (not listed in more specific categories) that cause infections and diseases in the body. It identifies the bacterial cause of a condition coded elsewhere. B96.89 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering bacterial and viral infectious agents (b95-b97).

B96.89 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28 or V24 community payment models, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.

Use when a specific bacterial organism is identified but does not fit into other B96 subcategories.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for B96.89 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
