ICD-10 Code B95.3 – Streptococcus pneumoniae as the cause of diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B95.3 – Streptococcus pneumoniae as the cause of diseases classified elsewhere
What it is
B95.3 identifies Streptococcus pneumoniae when it is documented as the infectious cause of another condition. Use it as an additional code, not as the main diagnosis.
Clinical signs
Clinical features vary; refer to documentation. The record should show pneumococcal infection linked to a separate disease process, such as pneumonia, meningitis, or otitis media.
When to use this code
Use B95.3 when the provider states Streptococcus pneumoniae is the causative organism for a condition classified elsewhere. Pair it with the code for the underlying disease, and code the infection source only when documented. If the organism is not specified, check documentation.
Do not use for
Do not use this code as the principal diagnosis or for pneumococcal disease itself. If another organism or an unspecified pathogen is documented, select the appropriate code instead.
Coding tip
Always confirm that Streptococcus pneumoniae is explicitly named as the cause before assigning B95.3.
