Code-Specific Risks
- Incorrectly coding as primary hyperparathyroidism
Coding Notes
- Ensure documentation specifies 'of renal origin' to use this code.
E21.1 - Secondary hyperparathyroidism, not elsewhere classified
Use when secondary hyperparathyroidism is due to non-renal causes.
Applicable To
- Secondary hyperparathyroidism due to vitamin D deficiency
Excludes
- Secondary hyperparathyroidism of renal origin (N25.81)
Clinical Validation Requirements
- Normal renal function
- Low vitamin D levels
- Elevated PTH
Coding Notes
Document the specific non-renal cause to use this code.
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 Secondary Hyperparathyroidism to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code N25.81.
Impact
Clinical: Leads to incorrect treatment plans., Regulatory: Non-compliance with coding standards., Financial: Potential for denied claims.
Mitigation Strategy
Always specify the cause of SHPT., Include relevant lab values in documentation.
Impact
Reimbursement: Incorrect coding can lead to reimbursement issues., Compliance: Non-compliance with coding guidelines., Data Quality: Affects accuracy of patient records.
Mitigation Strategy
Use N25.81 for SHPT due to CKD.
Impact
Risk of coding SHPT without specifying the cause.
Mitigation Strategy
Implement documentation checks for cause specification.
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.
