| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| N25.0 | Renal osteodystrophy | Use when renal osteodystrophy is confirmed by bone biopsy in CKD patients. |
|
| E21.1 | Secondary hyperparathyroidism, not elsewhere classified | Use when secondary hyperparathyroidism is documented in CKD patients. |
|
| M85.8 | Other specified disorders of bone density and structure | Use when bone disorder is documented without specific mention of renal osteodystrophy. |

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

- Osteoporosis (M81.0)
Clinical Validation Requirements
- Bone biopsy report showing TMV classification
- CKD stage documentation
Code-Specific Risks

Coding Notes
- Ensure biopsy confirmation for accurate coding.
E21.1 - Secondary hyperparathyroidism, not elsewhere classified
Use when secondary hyperparathyroidism is documented in CKD patients.
Applicable To
- Secondary hyperparathyroidism due to CKD
Excludes
- Primary hyperparathyroidism (E21.0)
Clinical Validation Requirements
- PTH >300 pg/mL
- CKD stage documentation
Coding Notes
Ensure documentation specifies secondary hyperparathyroidism.
M85.8 - Other specified disorders of bone density and structure
Use when bone disorder is documented without specific mention of renal osteodystrophy.
Applicable To
- Bone density disorder not specified as renal osteodystrophy
Excludes
- Osteoporosis (M81.0)
Clinical Validation Requirements
- DXA Z-score <-2.0
- Normal PTH/phosphorus levels
Coding Notes
Use only when no specific renal-related bone disorder is documented.
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 Mineral Bone Disease to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code N25.0.
Impact
Clinical: Leads to incomplete clinical picture., Regulatory: May result in coding audits., Financial: Potential for lower reimbursement.
Mitigation Strategy
Educate providers on documentation requirements., Use templates to ensure complete documentation.
Impact
Reimbursement: May lead to lower DRG weight and reimbursement., Compliance: Risk of audit failure due to lack of specificity., Data Quality: Decreases accuracy of clinical data.
Mitigation Strategy
Query for specific conditions like secondary hyperparathyroidism or renal osteodystrophy.
Impact
Risk of audits due to lack of specificity in coding CKD-MBD.
Mitigation Strategy
Ensure documentation specifies underlying conditions and confirmatory tests.
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.
