For pulmonologists, practice managers, and medical coders, bronchitis cases can be tricky when it comes to accurate coding. Missteps in ICD-10 or CPT selection can lead to claim denials, delayed reimbursements, and audit risks. At DigitixMD RCM, we help practices streamline coding for both acute and chronic bronchitis, ensuring claims are accurate, compliant, and timely.
Understanding Bronchitis in Clinical and Billing Contexts
Bronchitis is the inflammation of the bronchial tubes, which carry air in and out of the lungs. Patients often experience persistent cough, mucus production, and difficulty breathing.
- Acute Bronchitis: Typically caused by viral or bacterial infections, it is short-lived and usually resolves within days to a week.
- Chronic Bronchitis: A long-term condition often linked to smoking, environmental irritants, or COPD. Chronic bronchitis requires ongoing management and documentation for accurate coding.
Using proper ICD-10-CM codes ensures your documentation aligns with payer requirements and HIPAA regulations.
Why Precise Bronchitis Coding Matters
- Revenue Protection: Inaccurate codes can result in rejected claims or underpayment.
- Audit Defense: Unspecified or vague codes are often targeted in payer audits.
- Clinical Reporting: Correct coding supports public health monitoring and research.
At DigitixMD RCM, our certified coders prioritize accuracy and compliance, helping you reduce denials and optimize reimbursements.
ICD-10 Codes for Acute Bronchitis
When a patient presents with sudden-onset bronchitis, the coding depends on whether a pathogen has been identified. The default code is J20.9 (Acute bronchitis, unspecified) if no specific cause is documented.
Here’s a simplified guide for common pathogen-specific codes:
| ICD-10 Code | Description | Documentation Notes |
|---|---|---|
| J20.0 | Acute bronchitis due to Mycoplasma pneumoniae | Requires lab confirmation or physician documentation |
| J20.1 | Acute bronchitis due to Haemophilus influenzae | Must have confirmed bacterial etiology |
| J20.2 | Acute bronchitis due to Streptococcus | Only code if bacterial infection is documented |
| J20.4 | Acute bronchitis due to parainfluenza virus | Confirmed via lab or provider notes |
| J20.5 | Acute bronchitis due to RSV | Valid for billing 2025 cases |
| J20.6 | Acute bronchitis due to rhinovirus | Document onset and lab confirmation if available |
| J20.7 | Acute bronchitis due to echovirus | Rare; only when confirmed |
| J20.9 | Acute bronchitis, unspecified | Use when etiology is unknown; safest choice for compliance |
Tip: Only assign pathogen-specific codes if documentation supports it. Otherwise, unspecified coding is the most defensible option.
Coding Chronic Bronchitis
Chronic bronchitis is characterized by a productive cough lasting at least three months over two consecutive years.
- ICD-10 Code: J42 (Unspecified chronic bronchitis)
- Comorbid COPD: Report J44.9 as primary and J42 secondary if bronchitis exacerbates COPD symptoms.
- Asthma Overlap: Use J45.901 for asthma with exacerbation; avoid dual coding unless explicitly documented.
Accurate documentation—spirometry results, symptom history, and onset dates—helps reduce denials and ensures correct reimbursement.
Documentation Essentials
Successful billing starts with thorough clinical documentation:
- Patient History: Onset, duration, exposures (smoke, occupational hazards)
- Physical Exam: Breath sounds, wheezes, crackles
- Diagnostics: Labs, viral panels, chest X-rays
- Assessment & Plan: Etiology, treatment plan, follow-up care
- Secondary Codes: Tobacco history (Z87.891), other relevant comorbidities
- Time Documentation: Critical for E/M coding
Proper documentation safeguards claims against audits and ensures compliance with CMS and AAPC standards.
CPT & HCPCS Codes Relevant to Bronchitis
While ICD-10 codes cover the diagnosis, treatments and procedures require CPT/HCPCS codes:
- Evaluation & Management (E/M): 99213, 99214
- Pulmonary Tests/Spirometry: 94010, 94060
- Imaging: Chest X-ray (71046)
- Therapies: Nebulization (94640), oxygen therapy
- Medications (HCPCS): J7613 (albuterol), J1100 (steroids)
Always ensure proper modifiers, place-of-service codes, and correct diagnosis pointers for seamless claim submission.
2025 Coding Updates
- No significant changes to bronchitis-specific ICD-10 codes for 2025.
- Minor clarifications for inhalation-related bronchitis (J68.0) and respiratory exposures.
- Stay updated with CMS and AAPC releases to avoid compliance issues.
Common Billing Pitfalls
Frequent errors in bronchitis coding include:
- Using unspecified codes when specificity is documented
- Failing to include secondary codes (e.g., tobacco exposure)
- Overcoding unsupported pathogens
- Incorrect modifier or diagnosis pointer use
- Omitting documentation for comorbidities like COPD or asthma
DigitixMD RCM conducts pre-claim audits and denial management to address these errors, protecting your revenue and compliance.

Frequently Asked Questions
-
Which ICD-10 code should I use for acute bronchitis without a confirmed pathogen?
If the cause of acute bronchitis is not identified, the correct ICD-10 code is J20.9 (Acute bronchitis, unspecified). This is the safest and most defensible choice to avoid audit or denial risks. Only use pathogen-specific codes if lab confirmation or provider documentation supports it.
-
How do I code chronic bronchitis with coexisting COPD?
For patients with chronic bronchitis and COPD, report J44.9 (COPD, unspecified) as the primary diagnosis and J42 (Chronic bronchitis, unspecified) as a secondary diagnosis if bronchitis is contributing to symptoms. Ensure documentation supports the chronicity and severity to avoid claim issues.
-
Can acute bronchitis codes be applied without lab confirmation?
Yes, but only when coding the unspecified type (J20.9). Using pathogen-specific codes (like J20.0–J20.8) requires confirmed lab results or clear provider documentation. Assigning a specific pathogen without documentation may trigger denials or audits.
-
Are there any major changes to bronchitis coding in 2025?
There are no significant bronchitis-specific changes in 2025. Minor clarifications, such as coding bronchitis caused by inhalation of harmful gases (J68.0), may apply. Providers should monitor CMS and AAPC updates for upcoming FY 2026 changes.
-
What documentation is essential for defensible bronchitis coding?
Key documentation includes:
Onset and duration of symptoms
Patient history, including exposure to smoke or irritants
Physical exam findings (wheezing, crackles, breath sounds)
Lab tests, viral panels, imaging studies
Assessment, treatment plan, and follow-up
Secondary codes (e.g., tobacco history Z87.891) -
Which CPT or HCPCS codes are commonly paired with bronchitis visits?
Common codes include:
E/M codes: 99213, 99214
