| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| E83.50 | Calciphylaxis | Use when calciphylaxis is confirmed by biopsy and associated with CKD or dialysis. |

| N18.6 | End-stage renal disease | Use in conjunction with E83.50 when calciphylaxis is present. |

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
- Biopsy shows calcification in dermal arterioles.
documentation Criteria
- Patient has documented end-stage renal disease or is on dialysis.
Applicable To
- Calcific uremic arteriolopathy
Excludes
- Other disorders of calcium metabolism (E83.59)
Clinical Validation Requirements
- Biopsy confirmation of calcification in dermal arterioles
- Presence of end-stage renal disease or dialysis
Code-Specific Risks
- Misclassification if biopsy is not performed
- Omission of CKD stage coding
Coding Notes
- Ensure biopsy confirmation is documented before using E83.50.
N18.6 - End-stage renal disease
Use in conjunction with E83.50 when calciphylaxis is present.
Clinical Validation Requirements
- Documentation of chronic kidney disease stage 5
- Patient on dialysis
Coding Notes
Ensure CKD stage is documented.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Calciphylaxis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E83.50.
Impact
Clinical: Incomplete clinical picture., Regulatory: Non-compliance with coding standards., Financial: Potential reimbursement issues.
Mitigation Strategy
Always document CKD stage when coding calciphylaxis., Verify dialysis status is included in the documentation.
Impact
Reimbursement: Incorrect DRG assignment may affect reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Ensure biopsy confirms calciphylaxis before coding E83.50.
Impact
Coding E83.50 without biopsy confirmation.
Mitigation Strategy
Ensure biopsy results are documented before coding.
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.
