ICD-10 Code B71 – Other cestode infections (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B71 – Other cestode infections
What it is
B71 identifies infections caused by cestodes, or tapeworms, that are not captured by more specific ICD-10 codes. Use it when the record documents an unspecified or other cestode infection.
Clinical signs
Clinical features vary; refer to documentation. Patients may have gastrointestinal complaints, weight loss, or evidence of tapeworm infection, but the exact presentation depends on the species and site involved.
When to use this code
Use B71 when the provider documents a cestode infection and does not name a more specific organism or category. It also fits cases labeled as “other” cestode infection in the chart. If the species is identified, code the more specific option instead.
Do not use for
Do not use B71 for infections already assigned to a more specific cestode code, such as named tapeworm diseases. Check documentation if the record describes a different parasitic infection or a noninfectious intestinal condition.
Coding tip
Look for the parasite name in the assessment, lab report, or problem list before defaulting to B71.
