Code Description

ICD-10 A32.89 is a billable code used to indicate a diagnosis of other forms of listeriosis.

Key Diagnostic Point:

Listeriosis is an infection caused by the bacterium Listeria monocytogenes, which can lead to severe illness, particularly in vulnerable populations such as pregnant women, newborns, the elderly, and immunocompromised individuals. While the most common form of listeriosis presents as meningitis or septicemia, other forms can manifest as localized infections, including abscesses, endocarditis, and gastrointestinal infections. The clinical presentation may vary widely, with symptoms ranging from mild flu-like signs to severe neurological deficits. Diagnosis typically involves culture of the organism from blood, cerebrospinal fluid, or other sterile sites. Treatment usually consists of antibiotics, with ampicillin being the first-line agent. In cases of resistance or allergy, alternatives such as gentamicin may be used. The emergence of antibiotic-resistant strains of Listeria is a growing concern, necessitating careful monitoring and adherence to treatment protocols. Understanding the various forms of listeriosis is crucial for accurate diagnosis and effective management.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of listeriosis, enabling better tracking of epidemiological trends and treatment outcomes. A32.89 provides a means to capture cases that do not fit neatly into other categories, enhancing the granularity of data collection.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of listeriosis, enabling better tracking of epidemiological trends and treatment outcomes. A32.89 provides a means to capture cases that do not fit neatly into other categories, enhancing the granularity of data collection.

Frequently Asked Questions

What are the common symptoms of listeriosis?

Common symptoms include fever, muscle aches, nausea, diarrhea, and in severe cases, meningitis or septicemia.

How is listeriosis diagnosed?

Diagnosis is typically made through culture of Listeria monocytogenes from blood, cerebrospinal fluid, or other sterile sites.

What is the treatment for listeriosis?

Treatment usually involves antibiotics, with ampicillin being the first-line agent. In cases of resistance, alternatives like gentamicin may be used.
