| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| E83.39 | Other disorders of phosphorus metabolism | Use for acquired or idiopathic hyperphosphatemia or hypophosphatemia with documented etiology. |
|
| E83.31 | Familial hypophosphatemia | Use only for genetic disorders confirmed by genetic testing or family history. |

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

Essential facts and insights about Phosphorus Metabolism Disorders
Primary ICD-10-CM Codes for phosphorus
Decision Criteria
clinical Criteria
- Serum phosphate levels and underlying cause documentation
coding Criteria
- Sequence underlying condition first
Applicable To
- Hyperphosphatemia
- Hypophosphatemia
Excludes
- Familial hypophosphatemia (E83.31)
Clinical Validation Requirements
- Serum phosphate level >4.5 mg/dL for hyperphosphatemia
- Serum phosphate level <2.5 mg/dL for hypophosphatemia
- Documentation of underlying cause such as CKD or drug-induced
Code-Specific Risks
- Incorrect sequencing if underlying cause is not coded first
- Use of unspecified codes when specific etiology is known
Coding Notes
- Ensure documentation specifies the type and cause of phosphorus disorder.
E83.31 - Familial hypophosphatemia
Use only for genetic disorders confirmed by genetic testing or family history.
Applicable To
- X-linked hypophosphatemic rickets
Excludes
- Other disorders of phosphorus metabolism (E83.39)
Clinical Validation Requirements
- Genetic test report or family history
- Radiographic evidence of rickets/osteomalacia
Coding Notes
Ensure genetic confirmation is documented.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Chronic kidney disease, stage 5
N18.5Differential 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 Phosphorus Metabolism Disorders to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E83.39.
Impact
Clinical: May lead to inappropriate treatment decisions., Regulatory: Non-compliance with documentation standards., Financial: Potential denial of claims due to insufficient documentation.
Mitigation Strategy
Always document specific phosphate levels and related conditions.
Impact
Reimbursement: May lead to incorrect DRG assignment affecting reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Reduces accuracy of clinical data.
Mitigation Strategy
Always document and code the specific cause of the phosphorus disorder.
Impact
Failure to sequence underlying conditions first.
Mitigation Strategy
Educate coders on proper sequencing rules.
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.
