ICD-10 Code B95.0 – Streptococcus, group A, as the cause of diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B95.0 – Streptococcus, group A, as the cause of diseases classified elsewhere
What it is
B95.0 identifies group A Streptococcus as the organism causing another condition. You use it to show the infectious agent, not the primary disease itself.
Clinical signs
Clinical features vary; refer to documentation. The record should clearly link group A Streptococcus to the associated infection or disease being treated.
When to use this code
Use B95.0 when the provider documents group A Streptococcus as the cause of a separate diagnosed condition, such as a streptococcal infection classified elsewhere. Pair it with the code for the underlying disease. Do not use it alone as the primary diagnosis.
Do not use for
Do not use this code for nonspecific “strep” documentation without confirmation of group A, or when streptococcal disease is already captured by the main diagnosis code. Check documentation.
Coding tip
Assign B95.0 only after you confirm the organism and the related condition are both documented.
