A18.2

Billable

Tuberculous peripheral lymphadenopathy

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

This is tuberculosis infection that affects the lymph nodes outside the chest, such as those in the neck, armpits, or groin. The lymph nodes become swollen and inflamed due to the tuberculosis bacteria.

Coding Tips

  • •Verify that the tuberculosis is confirmed and specifically involves peripheral (non-thoracic) lymph nodes rather than chest lymph nodes, which would be coded differently
  • •This code should be used with a fifth character to indicate the bacteriological or histological confirmation status (e.g., A18.21 for bacteriologically and histologically confirmed)

Excludes 2 — Not included here, may code separately

  • tuberculosis of bronchial and mediastinal lymph nodes (A15.4)
  • tuberculosis of mesenteric and retroperitoneal lymph nodes (A18.39)
  • tuberculous tracheobronchial adenopathy (A15.4)
