Oculoglandular tularemia

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

What This Code Means

Oculoglandular tularemia is a bacterial infection caused by Francisella tularensis that affects the eye and nearby lymph nodes, typically occurring after the bacteria enters through the conjunctiva (eye membrane). This form of tularemia causes eye irritation, discharge, and swollen lymph nodes in front of the ear.

Coding Tips

  • •Verify that the infection specifically involves ocular (eye) manifestations with regional lymphadenopathy to distinguish from other forms of tularemia (A21.0, A21.2, A21.3, A21.8, A21.9)
  • •Document the source of exposure if known (animal contact, tick bite, contaminated water) as this may support medical necessity and help with epidemiological tracking
