Complete code families applicable to Renal Disorder
I12-I13Primary Range
Hypertensive heart and chronic kidney disease
This range includes codes for hypertensive heart disease with chronic kidney disease, which is a common cause of renal disorders.
Chronic kidney disease (CKD)
This range specifically categorizes the stages of chronic kidney disease, crucial for accurate coding and documentation.
Type 2 diabetes mellitus with diabetic chronic kidney disease
This code is used when diabetes is a contributing factor to chronic kidney disease.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I12.9 | Hypertensive chronic kidney disease with stage 1 through stage 4 chronic kidney disease, or unspecified chronic kidney disease | Use when hypertension is present with CKD stages 1-4 without ESRD. |
|
| N18.6 | End stage renal disease | Use when the patient has ESRD and is on dialysis. |

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

Primary ICD-10-CM Codes for renal disorder
Decision Criteria
clinical Criteria
- Presence of hypertension and CKD stages 1-4
documentation Criteria
- Explicit documentation linking hypertension to CKD
Applicable To
- Hypertensive CKD stages 1-4
Excludes
- Hypertensive heart AND chronic kidney disease (I13.-)
Clinical Validation Requirements
- Documentation of hypertension and CKD stages 1-4
Code-Specific Risks
- Incorrectly coding as I10 when CKD is present
Coding Notes
- Ensure hypertension and CKD are linked in documentation.
N18.6 - End stage renal disease
Use when the patient has ESRD and is on dialysis.
Applicable To
- ESRD
Excludes
- Acute renal failure (N17.-)
Clinical Validation Requirements
- eGFR <15 mL/min
- Documentation of dialysis dependence
Coding Notes
Ensure ESRD and dialysis are 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 Renal Disorder to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I12.9.
Impact
Clinical: Inaccurate assessment of disease severity., Regulatory: Non-compliance with coding standards., Financial: Potential underbilling for services.
Mitigation Strategy
Always document the CKD stage with eGFR values.
Impact
Reimbursement: Incorrect reimbursement due to improper coding., Compliance: Non-compliance with ICD-10 guidelines., Data Quality: Inaccurate data affecting patient records.
Mitigation Strategy
Use I12.9 or I12.0 depending on CKD stage.
Impact
Failure to document the causal relationship can lead to audit issues.
Mitigation Strategy
Ensure all documentation explicitly links hypertension to CKD.
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.
