Schistosomiasis [bilharziasis] (B65)

ICD-10 code section B65 covers schistosomiasis, a parasitic infection caused by Schistosoma species. This section is used to classify various types of schistosomiasis infections, including urinary, intestinal, and other less common forms diagnosed in patients.

The ICD-10 code B65 is essential for identifying schistosomiasis and its specific forms such as B65.0 for urinary schistosomiasis caused by Schistosoma haematobium, often referred to by synonyms like genitourinary tract schistosomiasis or urinary calculus in schistosomiasis. For intestinal schistosomiasis due to Schistosoma mansoni, B65.1 applies, covering conditions such as splenitis and hepatic involvement. The code B65.2 is detailed for infections by Schistosoma japonicum, associated with hepatosplenic illness. Skin-related manifestations like cercarial dermatitis, also known as sea bather's eruption or cutaneous schistosomiasis, are coded under B65.3. Other rare species infections fall under B65.8, while B65.9 encompasses unspecified schistosomiasis cases, including various systemic effects like neuroschistosomiasis and pulmonary schistosomiasis. Understanding these codes aids accurate documentation and distinguishes between types of schistosomal infections.

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Neuroschistosomiasis

SCHISTOSOMIASIS of the brain, spinal cord, or meninges caused by infections with trematodes of the genus SCHISTOSOMA (primarily SCHISTOSOMA JAPONICUM; SCHISTOSOMA MANSONI; and SCHISTOSOMA HAEMATOBIUM in humans). S. japonicum infections of the nervous system may cause an acute meningoencephalitis or a chronic encephalopathy. S. mansoni and S. haematobium nervous system infections are associated with acute transverse myelitis involving the lower portions of the spinal cord. (From Joynt, Clinical Neurology, 1998, Ch27, pp61-2)

Schistosomiasis

Infection with flukes (trematodes) of the genus SCHISTOSOMA. Three species produce the most frequent clinical diseases: SCHISTOSOMA HAEMATOBIUM (endemic in Africa and the Middle East), SCHISTOSOMA MANSONI (in Egypt, northern and southern Africa, some West Indies islands, northern 2/3 of South America), and SCHISTOSOMA JAPONICUM (in Japan, China, the Philippines, Celebes, Thailand, Laos). S. mansoni is often seen in Puerto Ricans living in the United States.

Schistosomiasis haematobia

A human disease caused by the infection of parasitic worms SCHISTOSOMA HAEMATOBIUM. It is endemic in AFRICA and parts of the MIDDLE EAST. Tissue damages most often occur in the URINARY TRACT, specifically the URINARY BLADDER.

Schistosomiasis japonica

Schistosomiasis caused by Schistosoma japonicum. It is endemic in the ASIA, EASTERN and affects the bowel, liver, and spleen.

Schistosomiasis mansoni

Schistosomiasis caused by Schistosoma mansoni. It is endemic in Africa, the Middle East, South America, and the Caribbean and affects mainly the bowel, spleen, and liver.
