E83.4Primary Range
Disorders of magnesium metabolism
This range includes codes for both hypomagnesemia and hypermagnesemia, which are primary conditions for magnesium screening.
Chronic kidney disease (CKD) stages 1-5
CKD stages often require magnesium monitoring due to altered renal handling of electrolytes.
Cramps and spasms
Used as an ancillary code when cramps are associated with magnesium deficiency.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| E83.42 | Hypomagnesemia | Use when there is documented low serum magnesium with clinical symptoms. |
|
| N18.3 | Chronic kidney disease, stage 3 | Use when CKD stage 3 is documented and magnesium monitoring is required. |

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

R25.2Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Magnesium Screening to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E83.42.
Impact
Clinical: Leads to incomplete clinical picture., Regulatory: May result in non-compliance with coding standards., Financial: Potential for claim denials.
Mitigation Strategy
Always document symptoms linked to magnesium levels.
Impact
Reimbursement: Incorrect coding may lead to claim denials., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Use E83.42 for hypomagnesemia with documented symptoms.
Impact
Lack of detailed symptom documentation linked to magnesium levels.
Mitigation Strategy
Ensure comprehensive documentation of symptoms and lab results.
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.
