021.0
ICD-9-CMThis code describes a specific form of tularemia characterized by both glandular involvement (lymphadenopathy) and ulceration at the site of inoculation. It represents a bacterial zoonotic infection caused by Francisella tularensis, typically acquired through contact with infected animals or insect bites.
Use this code when documentation clearly indicates a diagnosis of tularemia presenting with both an ulcer and regional lymph node enlargement. This is often seen following direct contact with infected animal tissue or a bite from an infected arthropod. Supporting documentation would include physician notes detailing the characteristic ulcer and palpable lymphadenopathy, along with positive diagnostic tests for F. tularensis.
