What is the ICD-10-CM Diagnosis Code for Other tuberculosis of the nervous system?
The ICD-10-CM diagnosis code for Other tuberculosis of the nervous system is A17.89.
Other tuberculosis of the nervous system refers to rare forms of TB that affect parts of the nervous system other than the brain or meninges.
It may involve the spinal cord, cranial nerves, or peripheral nerves. Symptoms depend on the area affected and may include weakness, numbness, confusion, seizures, or coordination problems.
The cause is infection by Mycobacterium tuberculosis, which spreads through the bloodstream from the lungs. Diagnosis involves imaging, cerebrospinal fluid tests, and sometimes biopsy.

History Background of ICD-10-CM Diagnosis Code A17.89
The ICD-9-CM system, first introduced in 1979, provided the initial framework for coding diseases and health-related conditions in the United States.
The ICD-9-CM diagnosis code for Other tuberculosis of the nervous system is 013.80.This coding remained consistent from 1979 to 2015.
While the ICD-9-CM system offered a basic approach to disease classification, modern healthcare needs more detail and specificity.
To address this, the ICD-10-CM system was launched in 2015, introducing a more comprehensive and accurate coding structure.
The transition from ICD-9-CM to ICD-10-9 CM significantly improved the ability to document and analyze conditions such as Other tuberculosis of the nervous system.
The 2025 edition of ICD-10-CM A17.89 became effective on October 1, 2024.
