Hymenolepiasis

Hymenolepiasis is an intestinal parasitic infection caused by tapeworms of the genus Hymenolepis, primarily Hymenolepis nana (dwarf tapeworm) or Hymenolepis diminuta (rat tapeworm). Infection typically occurs through ingestion of eggs or infected arthropods, leading to symptoms such as abdominal pain, diarrhea, anorexia, and weight loss, though many cases are asymptomatic.

This code is used when documentation confirms a diagnosis of hymenolepiasis based on laboratory identification of Hymenolepis eggs or proglottids in stool samples. It applies to both symptomatic and asymptomatic infections. Ensure the physician's diagnosis explicitly states hymenolepiasis.

• Do not confuse with other helminthic infections; confirm the specific Hymenolepis species if documented, but this code covers both.
• Code any associated symptoms (e.g., abdominal pain, diarrhea) separately if they are significant and documented as such.
• Documentation should clearly state the diagnosis of hymenolepiasis, ideally supported by laboratory findings.
