Typhoid and paratyphoid fevers (A01)

ICD-10 codes A01 cover typhoid and paratyphoid fevers, which are bacterial infections primarily affecting the intestines. These codes are used to document specific types and complications of infections caused by different Salmonella bacteria strains.

The ICD-10 code for typhoid fever includes A01.00 for unspecified cases and extends to various complications such as typhoid meningitis (A01.01), heart involvement (A01.02), pneumonia (A01.03), arthritis (A01.04), and osteomyelitis (A01.05). These distinguish severe manifestations of Salmonella Typhi infection. The section also covers paratyphoid fevers caused by Salmonella Paratyphi groups A, B, and C, each assigned unique codes A01.1, A01.2, and A01.3. The unspecified paratyphoid fever is coded as A01.4. Coders can rely on these to specify the type of Salmonella infection and any related complications.

Including synonyms like "infection of intestine caused by Salmonella group D" or "typhoid fever" linked to A01.00, or "Salmonella paratyphi colitis" for paratyphoid codes helps clarify proper coding. These distinctions support accurate reporting and treatment tracking of typhoid and paratyphoid conditions.

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.

Paratyphoid Fever

A prolonged febrile illness commonly caused by several Paratyphi serotypes of SALMONELLA ENTERICA. It is similar to TYPHOID FEVER but less severe.

Typhoid Fever

An acute systemic febrile infection caused by SALMONELLA TYPHI, a serotype of SALMONELLA ENTERICA.
