Other bacterial agents as the cause of diseases classified elsewhere (B96)

The ICD-10 code section B96 covers infections caused by various bacterial agents that lead to diseases primarily classified elsewhere in the ICD system. These codes specify the bacterial culprit behind conditions such as respiratory infections, urinary tract infections, or skin infections, providing precise identification when the disease is coded under another main diagnosis.

This section includes detailed codes like B96.0 for Mycoplasma pneumoniae infections, which encompass conditions referred to as mycoplasma-induced rash and mucositis or erythema multiforme due to bacterial infection. Codes B96.1 and B96.2 specify infections caused by Klebsiella pneumoniae and Escherichia coli (E. coli), respectively, common causes of urinary tract infections and neonatal infections. Notably, B96.81 identifies Helicobacter pylori as the cause of gastritis and ulcers. The use of these codes, such as the ICD-10 code for Klebsiella infections or E. coli infections, helps clarify the bacterial source when recorded diseases are originally classified elsewhere, aiding in comprehensive clinical documentation and treatment planning.

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.

Chorioamnionitis

INFLAMMATION of the placental membranes (CHORION; AMNION) and connected tissues such as fetal BLOOD VESSELS and UMBILICAL CORD. It is often associated with intrauterine ascending infections during PREGNANCY.
