ICD-10 codes for Bronchitis
Bronchitis is coded primarily under J20, J20.9, J40 in the ICD-10-CM (Clinical Modification) classification. Top-level categories include J20 (Acute bronchitis); J40 (Bronchitis, not specified as acute or chronic); J41 (Simple and mucopurulent chronic bronchitis); J42 (Unspecified chronic bronchitis). The 2025 ICD-10-CM code set includes 17 codes related to bronchitis, of which 15 are billable (specific enough to appear on a medical claim).
Bronchitis is inflammation of the bronchial tubes. Acute bronchitis is coded under J20 and J40 (unspecified, acute or chronic), while chronic bronchitis falls under J41 and J42. J44.0 represents COPD with acute lower respiratory infection, often documented during a bronchitis exacerbation.

Common examples include J20.0 (Acute bronchitis due to Mycoplasma pneumoniae); J20.1 (Acute bronchitis due to Hemophilus influenzae); J20.2 (Acute bronchitis due to streptococcus).

Always code to the highest level of specificity supported by the clinical documentation.
Is J20 a billable ICD-10 code?
No, J20 (Acute bronchitis) is a non-billable header code. You need to use a more specific child code for billing purposes.
What are the SNOMED CT concepts for bronchitis?
The ICD-10 codes for bronchitis map to at least 25 SNOMED CT concepts. Examples of SNOMED CT concept IDs in this group include 233598009, 233599001, 95886009, 195721005, 41048006. SNOMED CT is a clinical terminology used in electronic health records; AutoICD's coding API returns SNOMED CT IDs alongside each ICD-10 code via the include_snomed=true flag.
What UMLS Concept Unique Identifiers (CUIs) cover bronchitis?
The ICD-10 codes for bronchitis are linked to at least 25 UMLS CUIs in the National Library of Medicine's Metathesaurus. Sample CUIs include C0149514, C4290186, C4290187, C4290188, C4290189. UMLS CUIs unify the same concept across SNOMED CT, ICD-10, ICD-11, RxNorm, MeSH, and dozens of other source vocabularies.
What are other names for bronchitis in ICD-10?
Bronchitis may also be referred to as: bronchitis, acute bronchitis, chronic bronchitis, bronchitis cough. The same ICD-10-CM codes apply regardless of which term appears in the clinical documentation. Synonyms are surfaced by AutoICD's NER pass and mapped to the canonical ICD-10 family above.
