E87.1 - Hypo-osmolality and hyponatremia
Use when hyponatremia is the primary condition being treated.
Applicable To
- Hyponatremia
Excludes
- SIADH (E22.2)
Clinical Validation Requirements
- Na+ <135 mEq/L
- Symptoms such as confusion or seizures
Coding Notes
Hyponatremia should be documented with symptoms and lab values.
E87.5 - Hyperkalemia
Use when hyperkalemia is the primary condition being treated.
Applicable To
- Hyperkalemia
Clinical Validation Requirements
- K+ >5.0 mEq/L
- ECG changes such as peaked T waves
Coding Notes
Hyperkalemia should be documented with specific symptoms and lab values.
E87.6 - Hypokalemia
Use when hypokalemia is the primary condition being treated.
Applicable To
- Hypokalemia
Clinical Validation Requirements
- K+ <3.5 mEq/L
- Symptoms such as muscle weakness or cramps
Coding Notes
Hypokalemia should be documented with specific symptoms and lab values.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Abnormal Electrolytes to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E87.0.
Impact
Clinical: Incomplete clinical documentation., Regulatory: Non-compliance with documentation standards., Financial: Potential for claim denials.
Mitigation Strategy
Ensure provider includes a diagnosis with lab results., 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 the provider documents the specific electrolyte disorder.
Impact
Reimbursement: Incorrect DRG assignment affecting reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Misrepresentation of clinical priorities.
Mitigation Strategy
Sequence the underlying condition first, followed by the electrolyte disorder.
Impact
Risk of coding based on lab values without provider documentation.
Mitigation Strategy
Implement regular training on documentation requirements.
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.
