2025 ICD-10-CM code A07
(Active) Effective Date: N/A Certain infectious and parasitic diseases - Intestinal infectious diseases A00-B99 Feed
Other protozoal intestinal diseases.
Medical necessity is established by the presence of signs and symptoms of protozoal intestinal infection, confirmed by laboratory findings.
Clinicians diagnose based on symptoms (e.g., diarrhea, abdominal cramps, fatigue, gas, rectal pain, weight loss; in severe cases, bloody stools, fever, vomiting, abdominal tenderness), travel history, and physical exam. Lab tests of blood and stool confirm the diagnosis. Treatment includes antiprotozoal drugs (like metronidazole) and rehydration.
In simple words: This code refers to intestinal infections caused by parasites other than those specifically listed in other codes, like amebiasis or giardiasis. These infections are typically acquired by consuming contaminated food or water.
This code encompasses protozoal intestinal diseases not specifically classified elsewhere.It includes infections caused by various parasites, often ingested through contaminated food or water, leading to intestinal infection.
Example 1: A patient presents with chronic diarrhea, abdominal pain, and weight loss after returning from a trip overseas. Stool examination reveals the presence of Blastocystis hominis, a protozoan parasite. A07 is used for the diagnosis., A child experiences persistent watery diarrhea, gas, and abdominal discomfort.Microscopic examination of a stool sample identifies Dientamoeba fragilis. The diagnosis is coded as A07., An individual complains of recurring episodes of foul-smelling diarrhea and bloating. After ruling out other causes, a healthcare provider diagnoses the patient with intestinal protozoiasis caused by an unspecified organism, using code A07.
Documentation should include symptoms, travel history, physical exam findings, and laboratory results confirming the presence of the protozoan parasite.
** Excludes certain localized infections (see body system chapters), carrier status (Z22.-), infections complicating pregnancy, childbirth, and the puerperium (O98.-), and perinatal infections (P35-P39).
