What is the ICD-10-CM Diagnosis Code for Tuberculous meningoencephalitis?
The ICD-10-CM diagnosis code for Tuberculous meningoencephalitis is A17.82.
Tuberculous meningoencephalitis is a serious infection where tuberculosis bacteria affect both the brain and its protective membranes.
It usually develops as a complication of untreated or severe tuberculosis. Common symptoms include headache, fever, neck stiffness, confusion, and sometimes seizures or coma.
It is caused by Mycobacterium tuberculosis, which spreads through airborne droplets and may reach the brain through the bloodstream.
Early diagnosis is vital and is confirmed by brain imaging and cerebrospinal fluid analysis. Treatment involves a long course of anti-tuberculosis drugs, often combined with corticosteroids to reduce brain inflammation.
Proper documentation using A17.82 ensures patients receive appropriate care and enables accurate healthcare reimbursement.

History Background of ICD-10-CM Diagnosis Code A17.82
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 Tuberculous meningoencephalitis is 013.0.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-CM significantly improved the ability to document and analyze conditions such as Tuberculous meningoencephalitis.
The 2025 edition of ICD-10-CM A17.82 became effective on October 1, 2024.
