| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| E83.52 | Hypercalcemia | Use when hypercalcemia is the primary focus of treatment or a significant condition. |

Primary ICD-10-CM Codes for high calcium
Decision Criteria
clinical Criteria
- Serum calcium level >10.5 mg/dL with symptoms
coding Criteria
- Documented underlying cause of hypercalcemia
Clinical Validation Requirements
- Serum calcium level >10.5 mg/dL
- Symptoms such as confusion, bone pain, or polyuria
Code-Specific Risks
- Incorrectly coding without documented serum calcium levels
- Omitting underlying cause if known
Coding Notes
- Ensure documentation of serum calcium levels and any related symptoms.
E21.3 - Secondary hyperparathyroidism of renal origin
Use when hypercalcemia is secondary to renal-related hyperparathyroidism.
Applicable To
- Renal-related hyperparathyroidism
Excludes
- Primary hyperparathyroidism (E21.0)
Clinical Validation Requirements
- Elevated PTH levels
- Renal impairment indicators
Coding Notes
Ensure documentation of renal function and PTH levels.
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.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting High Calcium to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E83.52.
Impact
Clinical: Inadequate treatment planning, Regulatory: Non-compliance with coding standards, Financial: Potential claim denials
Mitigation Strategy
Always investigate and document underlying causes, Use additional codes for specific etiologies
Impact
Reimbursement: May lead to denial of claims due to lack of evidence., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Always document serum calcium levels when coding E83.52.
Impact
Failure to document serum calcium levels and symptoms.
Mitigation Strategy
Implement checklist for required documentation elements.
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.
