ICD-10 Code B95.5 – Unspecified streptococcus as the cause of diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B95.5 – Unspecified streptococcus as the cause of diseases classified elsewhere
What it is
Code B95.5 identifies unspecified streptococcus as the organism causing another condition classified elsewhere. You use it to name the bacterial cause, not the primary disease.
Clinical signs
Clinical features vary; refer to documentation. The record should indicate a streptococcal organism is implicated, but the species is not specified or is otherwise unspecified.
When to use this code
Use this code when the provider documents streptococcus as the cause of a separate infection or disease and does not identify the species. It is an additional code, so you must also code the underlying condition. Check documentation for the site and primary diagnosis.
Do not use for
Do not use B95.5 as the principal diagnosis. Do not use it when the organism is fully identified by another streptococcal code or when streptococcus is not documented as the cause.
Coding tip
Pair B95.5 with the documented primary condition and confirm the provider’s wording before assigning it.
