ICD-10-CM Billable Code

A18.7

Tuberculosis of adrenal glands

Clinical Classification Guidelines

Inclusion Terms

  • Tuberculous Addison's disease

Medical Intelligence & Overview

Tuberculosis of the adrenal glands, also known as tuberculous Addison's disease, is a rare form of tuberculosis that affects the adrenal glands located on top of the kidneys. These glands produce hormones essential for various body functions, including the regulation of metabolism, immune response, and stress. When infected by tuberculosis bacteria, the adrenal glands can become damaged, leading to hormonal deficiencies and related health issues. Recognizing and understanding this condition is crucial for proper diagnosis and management.

Causes & Symptoms

Clinical Causes: Infection with Mycobacterium tuberculosis, the bacteria causing tuberculosis Spread of tuberculosis from other parts of the body, such as the lungs, to the adrenal glands Progression of untreated or inadequately treated tuberculosis infection Reactivation of latent tuberculosis in individuals with compromised immune systems

Key Symptoms: Chronic fatigue and weakness Loss of appetite and unexplained weight loss Low blood pressure, leading to dizziness or fainting Hyperpigmentation of the skin, particularly in creases and scars Muscle and joint pain Gastrointestinal disturbances like nausea and abdominal pain Salt craving due to sodium imbalance Electrolyte disturbances such as hyponatremia and hyperkalemia Addisonian crisis in severe cases, characterized by sudden weakness, confusion, and shock

Diagnostic & Treatment

Diagnosis Path: Diagnosing tuberculosis of the adrenal glands involves a combination of clinical evaluation and laboratory tests. Imaging studies like CT scans or MRIs can reveal adrenal enlargement or destruction. Blood tests may indicate hormonal deficiencies typical of adrenal insufficiency. Molecular tests and cultures help confirm the presence of Mycobacterium tuberculosis. Sometimes, a biopsy of the adrenal tissue is performed to establish a definitive diagnosis.

Treatment Protocols: The management of tuberculous adrenal gland infection includes a long-term course of anti-tuberculosis medications, typically combining multiple antibiotics over several months. Hormonal replacement therapy is often necessary to address adrenal insufficiency, such as corticosteroids and mineralocorticoids. Monitoring treatment response through clinical assessments and imaging studies is important. In some cases, surgical intervention may be required if there is significant adrenal destruction or failure.

Reimbursement claims with a date of service on or after October 1, 2015 require the use of ICD-10-CM codes.
