ICD-10 Code B82.0 – Intestinal helminthiasis, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B82.0 – Intestinal helminthiasis, unspecified
What it is
B82.0 identifies an intestinal helminth infection when the parasite is known to be a worm but the specific species is not documented. Use it for nonspecific intestinal worm disease when the chart does not name the organism.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include abdominal discomfort, diarrhea, nausea, or visible worms in stool, but the diagnosis should be supported by a documented intestinal helminth infection.
When to use this code
Use B82.0 when the provider documents intestinal helminthiasis without identifying the worm species. It also fits cases where the record confirms an intestinal helminth infection, but the exact parasite is not available in the final note. Check documentation if a more specific organism is named elsewhere.
Do not use for
Do not use this code for helminth infections outside the intestine or for parasitic infections identified to a more specific ICD-10 code. If the organism is specified, code the more exact diagnosis instead.
Coding tip
Look for the organism name in the assessment, laboratory report, or discharge summary before defaulting to B82.0.
