ICD-10-CM Code For Trichinellosis: Group Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group B75 includes diagnoses for infections caused by Trichinella species, such as trichinellosis and related parasitic invasions that primarily affect muscle and systemic organs. These ICD-10-CM diagnosis codes are used to document confirmed or suspected parasitic infection, with details that capture severity, organ involvement, and complications such as myositis or systemic manifestations. Accurate coding within the ICD-10-CM B75 group supports complete clinical documentation, proper claim adjudication, and appropriate reimbursement.

ICD-10-CM B75: Trichinellosis Overview

The ICD-10-CM B75 group represents infections caused by Trichinella species, a parasitic roundworm acquired most commonly from undercooked meat. These diagnoses primarily affect the muscular and systemic systems due to larval encystment and inflammatory response. Accurate coding matters for correct case classification, surveillance, and reimbursement related to infectious disease treatment.

When to Use

Use a code from this group when clinical assessment, laboratory testing, or epidemiologic evidence indicates infection with Trichinella species. Assign codes that reflect the stage, organ involvement, and any documented complications to ensure specificity.

Typical Clinical Scenarios

An adult presents to the emergency department with fever, myalgias, periorbital edema, and new-onset muscle tenderness after recently eating undercooked wild boar meat. Laboratory testing shows eosinophilia and positive serology for Trichinella; the clinician documents an acute parasitic infection responsible for the patient’s systemic and muscular symptoms. Typical codes: B75
A middle-aged patient is evaluated in infectious disease clinic months after a documented Trichinella infection who continues to report chronic myalgia and persistent fatigue interfering with daily activities; follow-up serology remains positive and the care team documents ongoing sequelae of the prior helminthic infection. Typical codes: B75
An inpatient admission for cardiac arrhythmia and respiratory compromise in a patient who recently had a confirmed Trichinella exposure; workup attributes myocarditis and severe respiratory muscle weakness as complications of the parasitic infection and the diagnosis is recorded as a contributing infectious etiology. Typical codes: B75
