What is the ICD-10-CM Diagnosis Code for Tuberculous peripheral lymphadenopathy?
The ICD-10-CM diagnosis code for Tuberculous peripheral lymphadenopathy is A18.2.
Peripheral lymphadenopathy refers to the swelling of lymph nodes located outside the chest and abdomen, such as in the neck, armpits, or groin. It is usually a sign of infection or inflammation.
Tuberculous peripheral lymphadenopathy is a form of tuberculosis that affects these lymph nodes. It is caused by Mycobacterium tuberculosis. The infection often begins in the lungs and spreads to the lymph nodes.
Symptoms may include painless swelling of nodes, fever, weight loss, and night sweats. It is more common in children and young adults.
Diagnosis involves clinical examination, imaging, and biopsy. Treatment includes a full course of anti-tuberculosis medications. Early treatment helps prevent complications.
Proper documentation using A18.2 ensures patients receive appropriate care and enables accurate healthcare reimbursement.

History Background of ICD-10-CM Diagnosis Code A18.2
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 peripheral lymphadenopathy is 017.20.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 peripheral lymphadenopathy.
The 2025 edition of ICD-10-CM A18.2 became effective on October 1, 2024.
