Applicable To
- Chronic hyponatremia
Excludes
- SIADH (E22.2)
Clinical Validation Requirements
- Sodium level <135 mmol/L on ≥2 tests >48h apart
- Documentation of volume status and etiology
Code-Specific Risks
- Denials if sodium isn't low enough
- Insufficient documentation of chronicity
Coding Notes
- Ensure documentation specifies chronicity and underlying causes.
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.

E22.2Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Chronic Hyponatremia 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 patient condition, Regulatory: Non-compliance with coding standards, Financial: Potential for claim denials
Mitigation Strategy
Include volume status in all documentation, Use specific terms like 'euvolemic' or 'hypovolemic'
Impact
Reimbursement: Potential denials due to lack of clinical validation, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate representation of patient condition
Mitigation Strategy
Ensure sodium levels <135 mmol/L are documented on multiple occasions.
Impact
Coding E87.1 without sufficient clinical documentation
Mitigation Strategy
Ensure all documentation includes sodium levels and chronicity
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.
