Disorders of kidney and ureter not elsewhere classified
This range includes codes for renal-related disorders, including secondary hyperparathyroidism due to renal origin.
Chronic kidney disease (CKD)
This range is used to specify the stage of CKD, which is essential for coding hyperparathyroidism due to renal insufficiency.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| N25.81 | Secondary hyperparathyroidism of renal origin | Use when hyperparathyroidism is directly linked to CKD stages 3-5. |
|
| N18.3 | Chronic kidney disease, stage 3 | Use to specify CKD stage when coding N25.81. |

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

Decision Criteria
clinical Criteria

documentation Criteria
- Explicit mention of 'secondary to CKD'
Applicable To
- Hyperparathyroidism due to chronic kidney disease
Excludes
- Primary hyperparathyroidism (E21.0)
Clinical Validation Requirements
- Elevated PTH levels >300 pg/mL

- Explicit link between CKD and hyperparathyroidism
Code-Specific Risks
- Incorrectly coding as primary hyperparathyroidism
- Omitting CKD stage documentation
Coding Notes
- Ensure documentation explicitly links hyperparathyroidism to CKD.
N18.3 - Chronic kidney disease, stage 3
Use to specify CKD stage when coding N25.81.
Applicable To
- Moderate CKD
Excludes
- Acute kidney failure (N17.-)
Clinical Validation Requirements
- eGFR 30-59 mL/min/1.73 m²
Coding Notes
Ensure CKD stage is documented by the provider.
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 Hyperparathyroidism due to Renal Insufficiency to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code N25.81.
Impact
Clinical: Inaccurate clinical picture of patient's condition., Regulatory: Non-compliance with coding standards., Financial: Potential for denied claims.
Mitigation Strategy
Ensure CKD stage is documented in every encounter., Educate providers on importance of CKD staging.
Impact
Reimbursement: Incorrect DRG assignment leading to potential underpayment., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Ensure documentation specifies renal origin to use N25.81.
Impact
Inadequate documentation of CKD stage can lead to audit findings.
Mitigation Strategy
Implement regular training on CKD documentation.
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.
