A04.4 is a billable and specific ICD-10-CM code. Accurate documentation of A04.4 facilitates proper diagnosis, effective management, and correct reimbursement.
This guide outlines its use, official coding guidelines, and historical background.
ICD-10-CM Code for Other Intestinal E. coli Infection
The ICD-10-CM Diagnosis Code for Other intestinal E. coli infections is A04.4.
Other intestinal E. coli infections are gastrointestinal diseases caused by less common pathogenic Escherichia coli strains.
Depending on the strain and severity, these infections can lead to symptoms such as diarrhea, abdominal pain, and fever.
Unlike more recognized types like ETEC or EHEC, these strains are often grouped due to their varied and less frequent clinical presentations.
Proper documentation using A04.4 ensures patients receive appropriate care and enables accurate healthcare reimbursement.
Synonyms
- E coli enteritis
- Intestinal infection due to e. Coli
History Background of ICD-10-CM Diagnosis Code A04.4
The ICD-9-CM system, first introduced in 1979, provided the initial framework for coding diseases and health-related conditions in the United States.
The ICD-9-CM Diagnosis code for Other intestinal E. coli is 008.09. This coding remained consistent from 1979 to 2015.
While the ICD-9-CM system offered a basic approach to disease classification, modern healthcare needs more detail and specificity.
To address this, the ICD-10-CM system was launched in 2015, introducing a more comprehensive and accurate coding structure.
The transition from ICD-9-CM to ICD-10-CM significantly improved the ability to document and analyze conditions such as Other intestinal Escherichia coli infections.
The 2025 edition of ICD-10-CM A04.4 became effective on October 1, 2024
