What is the ICD-10-CM Diagnosis Code for Tuberculosis of the heart?
The ICD-10-CM diagnosis code for Tuberculosis of the heart is A18.84.
Tuberculosis of the heart is a rare but serious condition caused by Mycobacterium tuberculosis. It mainly affects the outer lining of the heart, called the pericardium.
Symptoms may include chest pain, shortness of breath, fatigue, and swelling in the legs or abdomen. The infection spreads from the lungs or other TB-affected areas through the blood.
It is more common in people with weak immunity. Diagnosis includes chest X-ray, echocardiogram, and TB tests.
Treatment involves anti-TB medications and sometimes procedures to drain fluid around the heart. Early treatment is important to prevent complications like heart failure.
Proper documentation using A18.84 ensures patients receive appropriate care and enables accurate healthcare reimbursement.
History Background of ICD-10-CM Diagnosis Code A18.84
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 Tuberculosis of the heart is 017.90(Tuberculosis of other specified organs, unspecified).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 Tuberculosis of the heart.
The 2025 edition of ICD-10-CM A18.84 became effective on October 1, 2024.
