| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| N14.11 | Contrast-induced nephropathy | Use when nephropathy is directly linked to contrast media exposure. |
|
| N14.19 | Other drug-induced nephropathy | Use for nephropathy linked to drugs other than contrast media. |
|
| N18.3 | Chronic kidney disease, stage 3 | Use for patients with moderate CKD, often associated with nephropathy. |

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

Essential facts and insights about Nephropathy
Primary ICD-10-CM Codes for nephropathy
Decision Criteria
clinical Criteria
- Documented contrast media exposure and subsequent creatinine elevation.
Applicable To
- Acute kidney injury due to contrast media
Excludes
- Acute kidney failure (N17.-)
Clinical Validation Requirements
- Elevated serum creatinine within 48-72 hours post-contrast administration
- Documented use of contrast media
Code-Specific Risks
- Incorrectly coding as acute kidney failure
Coding Notes
- Ensure documentation specifies contrast media use and timing of creatinine rise.
N14.19 - Other drug-induced nephropathy
Use for nephropathy linked to drugs other than contrast media.
Applicable To
- Nephropathy due to antibiotics, NSAIDs
Excludes
- Nephropathy due to contrast media (N14.11)
Clinical Validation Requirements
- Recent use of nephrotoxic drugs
- Presence of proteinuria or granular casts
Coding Notes
Ensure documentation specifies the drug and clinical signs of nephropathy.
N18.3 - Chronic kidney disease, stage 3
Use for patients with moderate CKD, often associated with nephropathy.
Applicable To
- Moderate CKD
Excludes
- Acute kidney failure (N17.-)
Clinical Validation Requirements
- eGFR between 30-59 mL/min/1.73m2
Coding Notes
Ensure accurate staging based on eGFR.
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 Nephropathy to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code N14.11.
Impact
Clinical: Leads to vague clinical data., Regulatory: Non-compliance with coding standards., Financial: Potential for denied claims.
Mitigation Strategy
Always specify the cause of nephropathy., Use specific ICD-10 codes.
Impact
Reimbursement: May lead to incorrect billing and reimbursement issues., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Reduces accuracy of clinical data.
Mitigation Strategy
Always document and code the specific cause of nephropathy, such as drug or contrast-induced.
Impact
Risk of audits due to incorrect or unspecified nephropathy coding.
Mitigation Strategy
Ensure detailed documentation and use of specific ICD-10 codes.
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.
