M63.1: Myositis in protozoal and parasitic infections classified elsewhere

Myositis in protozoal and parasitic infections classified elsewhere, as noted by the ICD-10 code M63.1, is a specific type of muscle inflammation. In this case, myositis is caused by protozoa or parasites that have infected the body through different means like ingestion, skin contact or through insect bites. Once these organisms are inside the body, they can travel to various organs, including muscles, to cause inflammation. Symptoms can vary depending on the parasite or protozoa causing the infection, but they commonly include muscle pain, aches, and weakness. Often, this condition might be accompanied by other symptoms of general infection such as fever, chills, and fatigue. The progression of these conditions largely depends on the type of parasite or protozoa causing the infection. It's also important to remember that these infections need to be classified elsewhere before being directly linked to myositis.
