| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| E87.5 | Hyperphosphatemia | Use when hyperphosphatemia is confirmed by lab tests and is the primary focus of care. |
|
| E83.39 | Other disorders of phosphorus metabolism | Use when hyperphosphatemia is part of a broader metabolic disorder. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Primary ICD-10-CM Codes for hyperphosphatemia
Decision Criteria
clinical Criteria
- Serum phosphate >5.5 mg/dL with symptoms
Applicable To
- Standalone hyperphosphatemia with lab confirmation
Excludes
- Hyperphosphatemia due to chronic kidney disease (use N18.x first)
Clinical Validation Requirements
- Serum phosphate >5.5 mg/dL
- Presence of symptoms such as muscle cramps or arrhythmias
Code-Specific Risks
- Incorrectly using this code for asymptomatic cases without lab confirmation
Coding Notes
- Ensure lab values and symptoms are documented to support the use of E87.5.
E83.39 - Other disorders of phosphorus metabolism
Use when hyperphosphatemia is part of a broader metabolic disorder.
Applicable To
- Hyperphosphatemia as part of broader metabolic disorders
Excludes
- Standalone hyperphosphatemia (use E87.5)
Clinical Validation Requirements
- Serum phosphate >5.5 mg/dL
- Presence of a broader metabolic disorder
Coding Notes
Document the underlying metabolic disorder to support the use of E83.39.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Chronic kidney disease (CKD)
N18.xDifferential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Hyperphosphatemia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E87.5.
Impact
Clinical: Leads to incorrect diagnosis coding., Regulatory: Potential for audit issues., Financial: May result in denied claims.
Mitigation Strategy
Ensure clear documentation of the underlying cause.
Impact
Reimbursement: Incorrect code may lead to denied claims., Compliance: Non-compliance with ICD-10 guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Use E87.5 for standalone hyperphosphatemia confirmed by labs.
Impact
Using E83.39 instead of E87.5 for standalone cases.
Mitigation Strategy
Educate coders on proper code selection criteria.
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.
