What is ICD diagnosis code A01.00

ICD code A01.00 is used to classify a diagnosis of typhoid fever when the specific details or complications of the condition are not specified. This code is part of the International Classification of Diseases (ICD) system, which is used by healthcare providers to standardize the reporting and tracking of diseases and conditions.

1. Fever: Persistent high fever that may fluctuate but generally remains elevated over several days.

2. Abdominal Pain: Generalized or localized abdominal discomfort, often accompanied by tenderness.

3. Headache: Severe headache that is persistent and not relieved by common analgesics.

4. Fatigue and Weakness: Significant fatigue and malaise that affects daily activities and persists over time.

5. Gastrointestinal Symptoms: Nausea, vomiting, and diarrhea or constipation, often with a change in bowel habits.

7. Splenomegaly: Enlargement of the spleen, detectable through physical examination or imaging.

8. Hepatomegaly: Enlargement of the liver, which may be accompanied by jaundice in some cases.

9. Bradycardia: Relative slowing of the heart rate, particularly during fever episodes.

10. Leukopenia: A decrease in white blood cell count, often observed in blood tests.

11. Positive Blood Culture: Isolation of the causative organism from blood cultures, confirming the diagnosis.

12. Travel History: Recent travel to areas where the condition is endemic or exposure to known sources of infection.
