Contagious Disease - Tuberculosis is indicated by which code?

• A. 20T
• B. 20A
• C. 20H
• D. 10

Answer: (A)

Contagious disease codes use a leading number to mark the broad category and a trailing letter to specify the exact condition. The letter T is the designation for Tuberculosis, so the code that combines 20 with T signals Contagious Disease – Tuberculosis. This is why this code is the correct one: it uniquely identifies TB among contagious-disease codes. Other trailing letters would point to different conditions, and a standalone number like 10 belongs to a different signaling category altogether, not contagious disease.
