Other intestinal helminthiases, not elsewhere classified (B81)

ICD-10 code section B81 covers various intestinal helminth infections that are not classified elsewhere, identifying specific parasitic worm diseases of the intestines beyond the common types. These codes help pinpoint diagnoses like anisakiasis and other rare worm infections.

This section includes codes such as B81.0 for Anisakiasis, a parasitic infection caused by larvae of the Anisakis family, which might also be called infections by Pseudoterranova or other Anisakidae larvae. B81.1intestinal capillariasis, linked to Capillaria species infections. The B81.2 code captures trichostrongyliasis, caused by several Trichostrongylus parasites. B81.3 stands for intestinal angiostrongyliasis, a condition caused by Angiostrongylus larvae. Mixed infections from different helminths fall under B81.4, while B81.8 records other specific intestinal helminthiasis infections with various parasites. Recognizing these specific ICD-10 codes is essential for accurate diagnosis and treatment documentation of these less common but distinct parasitic intestinal diseases.

Instructional Notations

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

  • angiostrongyliasis due to:
  • Angiostrongylus cantonensis B83.2
  • Parastrongylus cantonensis B83.2

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.

Anisakiasis

Infection with roundworms of the genus ANISAKIS. Human infection results from the consumption of fish harboring roundworm larvae. The worms may cause acute NAUSEA; VOMITING; or penetrate into the wall of the DIGESTIVE TRACT where they give rise to EOSINOPHILIC GRANULOMA in the STOMACH; INTESTINES; or the OMENTUM.
