ICD-10 Code B75 – Trichinellosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B75 – Trichinellosis
What it is
B75 identifies trichinellosis, a parasitic infection caused by Trichinella larvae. You use it when the record documents this specific helminth infection.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include fever, muscle pain, swelling, and gastrointestinal symptoms after exposure to undercooked meat.
When to use this code
Use B75 when the clinician diagnoses trichinellosis or trichinosis and the chart supports that diagnosis. It may be documented after ingestion of contaminated pork, wild game, or another Trichinella source. Code the condition only when it is clearly stated or confirmed in the record.
Do not use for
Do not use B75 for nonspecific foodborne illness, undifferentiated parasitic infection, or muscle pain without a documented Trichinella diagnosis. Check documentation if the organism is not identified.
Coding tip
Look for the exact parasite name in the assessment, problem list, or discharge diagnosis before assigning B75.
