- Serum sodium <135 mEq/L confirmed by lab tests
documentation Criteria
- Absence of specific etiology documented
Applicable To
- Generalized hypo-osmolality
- Hyponatremia NOS
Excludes
- Hyponatremia due to specific conditions like SIADH (E22.2)
Clinical Validation Requirements

- Omitting documentation of serum sodium levels
Coding Notes
- Ensure documentation includes serum sodium levels and osmolality.
Ancillary Codes

E22.2Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Hyponatremia Unspecified to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E87.1.
Impact
Clinical: Inadequate assessment of hyponatremia severity, Regulatory: Non-compliance with coding standards, Financial: Potential claim denials
Mitigation Strategy
Include osmolality in lab results, Cross-check documentation before submission
Impact
Reimbursement: Potential claim denials due to lack of evidence, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate clinical data representation
Mitigation Strategy
Ensure lab results confirm sodium levels before coding.
Impact
Failure to document all necessary clinical indicators for hyponatremia
Mitigation Strategy
Implement a checklist for required documentation elements
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.
