E87.5-E87.6Primary Range
Disorders of potassium balance
This range includes codes for hyperkalemia and hypokalemia, which are primary conditions related to abnormal potassium levels.
Hypertensive chronic kidney disease with stage 5 chronic kidney disease or end stage renal disease
This code is used when hyperkalemia is associated with hypertensive chronic kidney disease.
Chronic kidney disease, stage 3 (moderate)
This code is relevant when chronic kidney disease stage 3 is present with electrolyte imbalances.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| E87.5 | Hyperkalemia | Use when lab tests confirm hyperkalemia and clinical symptoms are present. |

Primary ICD-10-CM Codes for potassium level
Decision Criteria
clinical Criteria
- Potassium level >5.0 mmol/L with clinical symptoms
documentation Criteria
- Provider documentation explicitly states hyperkalemia
Applicable To
- Elevated potassium level
Excludes
- Pseudohyperkalemia
Clinical Validation Requirements
- Potassium level >5.0 mmol/L
- Clinical symptoms such as muscle weakness or ECG changes
Code-Specific Risks
- Misdiagnosis if pseudohyperkalemia is not ruled out
Coding Notes
- Ensure provider documentation supports hyperkalemia diagnosis.
E87.6 - Hypokalemia
Use when lab tests confirm hypokalemia and treatment is required.
Applicable To
- Low potassium level
Excludes
- Hypokalemia due to diuretics without symptoms
Clinical Validation Requirements
- Potassium level <3.5 mmol/L
- Symptoms such as muscle cramps or ECG changes
Coding Notes
Document any treatment or supplementation required for hypokalemia.
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.

R79.89Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Potassium Level Disorders to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E87.5.
Impact
Clinical: May lead to inappropriate treatment decisions., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims.
Mitigation Strategy
Ensure all lab results are accompanied by clinical interpretation., Train staff on documentation standards.
Impact
Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Ensure provider explicitly documents hyperkalemia diagnosis.
Impact
Reimbursement: Potential for claim rejections., Compliance: Violation of coding standards., Data Quality: Misleading clinical records.
Mitigation Strategy
Verify if treatment or supplementation is documented.
Impact
Inadequate documentation of potassium levels and related symptoms.
Mitigation Strategy
Implement regular documentation audits and training.
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.
