| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I31.31 | Malignant pericardial effusion | Use when the effusion is confirmed as malignant, secondary to a neoplasm. |
|
| I31.39 | Other noninflammatory pericardial effusion | Use for non-malignant, non-inflammatory effusions. |
|
| I31.4 | Cardiac tamponade | Use when effusion results in cardiac tamponade. |

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

Primary ICD-10-CM Codes for pericardial effusion
Decision Criteria
clinical Criteria
- Presence of malignant cells in pericardial fluid
Applicable To
- Malignant pericardial effusion due to cancer
Excludes
- Non-malignant pericardial effusion
Clinical Validation Requirements
- Cytology/pathology report stating 'malignant cells'
Code-Specific Risks
- Incorrect sequencing without primary neoplasm code
Coding Notes
- Ensure documentation specifies 'malignant' and links to primary cancer.
I31.39 - Other noninflammatory pericardial effusion
Use for non-malignant, non-inflammatory effusions.
Applicable To
- Noninflammatory effusion post-MI or uremic
Excludes
- Malignant pericardial effusion
Clinical Validation Requirements
- CRP <10 mg/L, absence of fever, non-purulent fluid
Coding Notes
Document absence of infection or malignancy.
I31.4 - Cardiac tamponade
Use when effusion results in cardiac tamponade.
Applicable To
- Pericardial effusion causing hemodynamic compromise
Excludes
- Non-tamponade pericardial effusion
Clinical Validation Requirements
- Echo showing ≥10mm effusion + right atrial collapse
Coding Notes
Ensure documentation of hemodynamic compromise.
Ancillary Codes

C78.2Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Pericardial Effusion to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I31.31.
Impact
Clinical: May lead to inappropriate treatment decisions., Regulatory: Non-compliance with coding guidelines., Financial: Potential for claim denials.
Mitigation Strategy
Ensure detailed documentation of effusion type and cause.
Impact
Reimbursement: May lead to claim denials or incorrect DRG assignment., Compliance: Non-compliance with ICD-10 specificity requirements., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Require specificity: Document ‘malignant’ or ‘other noninflammatory’ effusion.
Impact
Failure to sequence primary neoplasm code before I31.31.
Mitigation Strategy
Educate coding staff on proper sequencing rules.
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.
