2025 ICD-10-CM code A32.9
(Active) Effective Date: N/A Bacterial infections - Other bacterial diseases Certain infectious and parasitic diseases Feed
Listeriosis, unspecified.
Medical necessity for treatment of listeriosis is established by the confirmed presence of Listeria infection, as this can lead to serious complications if left untreated, especially in high-risk individuals.
Clinicians diagnose listeriosis based on patient symptoms (e.g., fever, muscle aches, diarrhea, headache, confusion, loss of balance, convulsions), exposure history, and physical examination. Laboratory tests of blood, spinal fluid, or placenta can confirm the presence of *Listeria monocytogenes*. Treatment typically involves antibiotics and rehydration therapy.
In simple words: This code represents listeriosis, a bacterial infection caused by eating contaminated food or contact with infected animals or environments.It's especially dangerous for pregnant women, babies, the elderly, and those with weakened immune systems.
This code indicates a listeriosis infection where the specific type is not documented.Listeriosis is a serious infection typically caused by ingesting food contaminated with the bacterium *Listeria monocytogenes*. It can also be contracted through contact with infected animals, soil, or vegetation. Pregnant women, newborns, older adults, and individuals with weakened immune systems are particularly vulnerable.
Example 1: A 70-year-old man presents with fever, muscle aches, and diarrhea after consuming contaminated deli meat.Laboratory tests confirm Listeria monocytogenes, and he is diagnosed with listeriosis (A32.9)., A pregnant woman experiences fever, fatigue, and muscle pain.Tests reveal Listeria monocytogenes, indicating listeriosis (A32.9), which poses a risk to both the mother and the fetus., A newborn develops fever, irritability, and poor feeding shortly after birth.The infant is diagnosed with listeriosis (A32.9), likely contracted from the mother during pregnancy or delivery.
Documentation should include signs and symptoms, patient history (including recent food intake and potential exposures), laboratory results confirming Listeria infection, and treatment plan.
