Is A17.81 an HCC code?
No. A17.81 is a billable ICD-10-CM code but does not map to any HCC category in V28, V24, ESRD, or RxHCC.
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
A17.81 is the ICD-10-CM diagnosis code for tuberculoma of brain and spinal cord. A tuberculoma is a tumor-like mass caused by tuberculosis infection that develops in the brain or spinal cord. This is a serious complication of tuberculosis where the infection spreads to the central nervous system and forms a localized collection of infected tissue. A17.81 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering tuberculosis (a15-a19).
A17.81 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.
This code should only be used when tuberculosis has specifically affected the brain or spinal cord with formation of a tuberculoma; do not use for general TB meningitis (use A17.0 instead).
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for A17.81 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This code should only be used when tuberculosis has specifically affected the brain or spinal cord with formation of a tuberculoma; do not use for general TB meningitis (use A17.0 instead)
- •Verify documentation confirms both the tuberculosis diagnosis and the specific location (brain and/or spinal cord) before assigning this code, as it may require additional imaging confirmation
