Buddy Documentation Tip

HCC Buddy guidance
Always verify that tuberculosis of the meninges is documented in the medical record before coding A17.0; do not assume TB meningitis from meningitis alone
This code should be used in conjunction with a code from category A15-A19 to indicate the site of tuberculosis, and may require additional codes for complications or manifestations

Is A17.0 an HCC code?

A17.0 is not in the CMS-HCC V28 or V24 community payment model. A17.0 also appears in the HHS-HCC commercial risk model (HCC 003 (HHS-HCC 003 adult, RAF varies by metal level)), which is a commercial market model rather than a Medicare Advantage payment mapping.

What This Code Means

A17.0 is the ICD-10-CM diagnosis code for tuberculous meningitis. This is a serious infection of the membranes surrounding the brain and spinal cord caused by tuberculosis bacteria. It is a life-threatening condition that requires immediate medical treatment with anti-tuberculosis medications. A17.0 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering tuberculosis (a15-a19).

A17.0 has no mapping under the CMS-HCC V28 or V24 community payment models. A17.0 also appears in the HHS-HCC commercial risk model (HCC 003 (HHS-HCC 003 adult, RAF varies by metal level)), which is a commercial market model rather than a Medicare Advantage payment mapping. Do not assign V28 risk adjustment value from this page; verify the applicable model and payment year before using this code for risk adjustment.

Always verify that tuberculosis of the meninges is documented in the medical record before coding A17.0; do not assume TB meningitis from meningitis alone.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for A17.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
