ICD-10 Code B96.29 – Other Escherichia coli [E. coli] as the cause of diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B96.29 – Other Escherichia coli [E. coli] as the cause of diseases classified elsewhere
What it is
This code identifies E. coli as the infectious cause of another condition classified elsewhere. Use it when documentation links “other E. coli” to the underlying disease, not as the primary diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Findings usually reflect the related infection site, such as urinary, abdominal, or wound involvement, with E. coli named as the causative organism.
When to use this code
Use B96.29 when the provider documents other E. coli as the cause of a condition coded elsewhere, such as an infection, inflammation, or complication. Pair it with the code for the underlying disease. Do not use it alone to describe the illness.
Do not use for
Do not use this code for unspecified E. coli, E. coli sepsis, or a primary diagnosis of E. coli infection. Check documentation if the organism is not clearly identified as “other” E. coli.
Coding tip
Confirm the linked condition first, then add B96.29 only when the record explicitly names other E. coli as the cause.
