| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| E87.5 | Hyperkalemia | Use as primary when hyperkalemia is the main reason for admission or treatment. |

E87.6Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Elevated Potassium to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E87.5.
Impact
Clinical: Inaccurate representation of patient's condition., Regulatory: Potential audit issues., Financial: Incorrect DRG assignment.
Mitigation Strategy
Always specify CKD stage if known.
Impact
Reimbursement: May result in denied claims if not properly documented., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Ensure documentation includes clinical symptoms or ECG findings.
Impact
Coding hyperkalemia without symptoms or ECG changes.
Mitigation Strategy
Ensure all documentation includes clinical correlation.
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.
