| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| E58 | Dietary calcium deficiency | Use when calcium deficiency is confirmed to be due to dietary insufficiency. |
|
| E83.51 | Hypocalcemia | Use for hypocalcemia related to metabolic or endocrine disorders. |
|
| E20.810 | Autosomal dominant hypocalcemia | Use when genetic testing confirms autosomal dominant hypocalcemia. |

Decision Criteria
clinical Criteria
- Dietary intake assessment confirms insufficient calcium intake.
coding Criteria
- Exclude metabolic causes before using E58.
Applicable To
- Calcium deficiency due to inadequate dietary intake
Excludes
- Hypocalcemia (E83.51)
Clinical Validation Requirements
- Serum calcium <8.5 mg/dL
- Dietary intake <600 mg/day
Code-Specific Risks
- Misclassification if metabolic cause is present
Coding Notes
- Ensure dietary cause is documented before using E58.
E83.51 - Hypocalcemia
Use for hypocalcemia related to metabolic or endocrine disorders.
Applicable To
- Hypocalcemia due to metabolic or endocrine disorders
Excludes
- Dietary calcium deficiency (E58)
Clinical Validation Requirements
- Ionized calcium <1.0 mmol/L
- PTH <15 pg/mL
Coding Notes
Always document the underlying cause of hypocalcemia.
E20.810 - Autosomal dominant hypocalcemia
Use when genetic testing confirms autosomal dominant hypocalcemia.
Applicable To
- Genetic hypoparathyroidism
Clinical Validation Requirements
- Genetic testing confirming CASR mutation
Coding Notes
Ensure genetic confirmation is documented.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Calcium Deficiency to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E58.
Impact
Clinical: Inadequate treatment planning, Regulatory: Potential audit issues, Financial: Incorrect billing
Mitigation Strategy
Include specific lab results and clinical signs.
Impact
Reimbursement: Incorrect DRG assignment, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate clinical data
Mitigation Strategy
Use E83.51 with CKD code.
Impact
Using E58 for metabolic causes of hypocalcemia.
Mitigation Strategy
Educate coders on the difference between dietary and metabolic causes.
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.
