ICD-10 Code J20.2 – Acute bronchitis due to streptococcus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J20.2 – Acute bronchitis due to streptococcus
What it is
J20.2 identifies acute bronchitis caused by streptococcal infection. Use it when the provider documents acute bronchitis and specifically names streptococcus as the cause.
Clinical signs
Typical findings include an acute cough with bronchial inflammation, often with sputum production or chest discomfort. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly links acute bronchitis to streptococcus, such as “streptococcal bronchitis” or “acute bronchitis due to strep.” It may also apply when the clinician confirms streptococcal etiology in the assessment. If the organism is not specified, check documentation.
Do not use for
Do not use J20.2 for bronchitis caused by another organism or for acute bronchitis with no documented streptococcal cause. Do not assign it when the note only says upper respiratory infection or pharyngitis.
Coding tip
Confirm that both the acute bronchitis diagnosis and streptococcal cause are documented before assigning J20.2.
