Cysticercosis

This code represents cysticercosis, a parasitic tissue infection caused by the larval cysts of the pork tapeworm, Taenia solium. The cysts can develop in various tissues, including muscle, subcutaneous tissue, and, most critically, the central nervous system (neurocysticercosis).

Use this code when documentation confirms a diagnosis of cysticercosis, regardless of the affected body system. This includes cases identified through imaging (e.g., CT, MRI showing cysts), serological tests, or biopsy. It is appropriate for both symptomatic and asymptomatic presentations of the infection.

• Always specify the anatomical site of the cysticercosis with an additional code if known (e.g., neurocysticercosis).
• Distinguish from taeniasis, which is the intestinal infection with the adult tapeworm and coded separately.
• Ensure documentation clearly differentiates between active infection and sequelae, as different codes may apply for residual conditions.
