What This Code Means
A17.83 is the ICD-10-CM diagnosis code for tuberculous neuritis. This is an infection of the nerves caused by tuberculosis bacteria, which can cause inflammation, pain, and weakness in the affected nerves. It's a serious complication that occurs when TB spreads from the lungs or other parts of the body to nerve tissue. A17.83 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering tuberculosis (a15-a19).
A17.83 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.
Verify that the documentation specifically states tuberculosis affecting the nervous system or nerves, not just general TB; neuritis indicates nerve inflammation from TB.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for A17.83 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify that the documentation specifically states tuberculosis affecting the nervous system or nerves, not just general TB; neuritis indicates nerve inflammation from TB
- •Ensure this code is used only for confirmed TB cases; if TB status is uncertain or ruled out, do not assign this code
