| 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 documenting hypertension with CKD stages 1-4 without heart failure. |
|
| I12.0 | Hypertensive chronic kidney disease with stage 5 chronic kidney disease or end stage renal disease | Use when documenting hypertension with CKD stage 5 or ESRD. |

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 hypertension with chronic kidney disease
Decision Criteria
clinical Criteria
- Presence of hypertension with CKD stages 1-4
Applicable To
- Hypertension with CKD stage 1-4
Excludes
- Hypertensive heart AND chronic kidney disease (I13.-)
Clinical Validation Requirements
- eGFR 15-89 mL/min
- Urine albumin ≥30 mg/g
Code-Specific Risks
- Ensure CKD stage is documented to avoid unspecified coding.
Coding Notes
- Always document the stage of CKD when using I12.9.
I12.0 - Hypertensive chronic kidney disease with stage 5 chronic kidney disease or end stage renal disease
Use when documenting hypertension with CKD stage 5 or ESRD.
Applicable To
- Hypertension with CKD stage 5 or ESRD
Excludes
- Hypertensive heart AND chronic kidney disease (I13.-)
Clinical Validation Requirements
- eGFR <15 mL/min
- Dialysis dependency
Coding Notes
Document dialysis status or eGFR to support coding.
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 Hypertension with Chronic Kidney Disease 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 clinical data representation., Regulatory: Non-compliance with ICD-10 guidelines., Financial: Potential for reduced reimbursement.
Mitigation Strategy
Always document the relationship between hypertension and CKD., Use specific ICD-10 codes for hypertensive CKD.
Impact
Reimbursement: Incorrect coding may lead to lower reimbursement rates., Compliance: Non-compliance with ICD-10 guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Use I12.9 or I12.0 to reflect the causal relationship between hypertension and CKD.
Impact
Failure to document or code the correct CKD stage.
Mitigation Strategy
Implement regular training on CKD staging and 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.
