| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| J43.2 | Centrilobular emphysema | Use when CT confirms centrilobular emphysema, typically in smokers. |
|
| J43.1 | Panlobular emphysema | Use when panlobular emphysema is confirmed, often in genetic cases. |
|
| J43.0 | MacLeod’s syndrome | Use when unilateral hyperlucency is confirmed on imaging. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Essential facts and insights about Emphysema
Primary ICD-10-CM Codes for emphysema
Decision Criteria
clinical Criteria
- CT confirms centrilobular emphysema
documentation Criteria
- Document tobacco use history
Applicable To
- Centrilobular emphysema confirmed by CT
Excludes
- COPD with chronic bronchitis (J44.-)
Clinical Validation Requirements
- CT showing centrilobular destruction
- FEV1/FVC <0.7
Code-Specific Risks
- Misclassification if CT findings are not documented
Coding Notes
- Ensure CT findings are documented to support this code.
J43.1 - Panlobular emphysema
Use when panlobular emphysema is confirmed, often in genetic cases.
Applicable To
- Panlobular emphysema associated with alpha-1 antitrypsin deficiency
Excludes
- Chemical-induced emphysema (J68.4)
Clinical Validation Requirements
- Serum A1AD level <11 µmol/L
- Panlobular pattern on CT
Coding Notes
Document genetic testing results to support this code.
J43.0 - MacLeod’s syndrome
Use when unilateral hyperlucency is confirmed on imaging.
Applicable To
- Unilateral hyperlucency consistent with MacLeod’s syndrome
Excludes
- Mediastinal emphysema (J98.2)
Clinical Validation Requirements
- Unilateral hyperinflation on imaging
- V/Q scan mismatch >20%
Coding Notes
Ensure imaging findings are documented to support this code.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Emphysema to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code J43.2.
Impact
Clinical: May lead to inappropriate treatment plans., Regulatory: Non-compliance with coding guidelines., Financial: Potential for reduced reimbursement.
Mitigation Strategy
Ensure detailed documentation of imaging and clinical findings.
Impact
Reimbursement: Incorrect coding may lead to reduced reimbursement., Compliance: Non-compliance with 2024 Coding Clinic guidelines., Data Quality: Inaccurate data representation of patient conditions.
Mitigation Strategy
Code only emphysema when both COPD and emphysema are present.
Impact
High risk of audit if J43.9 is used without specific documentation.
Mitigation Strategy
Ensure specific emphysema type is documented and coded.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
