| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| Z87.19 | Personal history of other diseases of the genitourinary system | Use when AKI is fully resolved with normal renal function and no CKD. |
|
| N17.9 | Acute kidney failure, unspecified | Use for active AKI episodes. |

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 history of acute kidney injury
Decision Criteria
clinical Criteria
- Resolved AKI with baseline creatinine restored
documentation Criteria
- Absence of CKD documentation
Applicable To
- Resolved acute kidney injury
Clinical Validation Requirements
- Documentation of resolved AKI with creatinine returning to baseline
- Absence of current CKD (GFR ≥60 for ≥3 months)
Code-Specific Risks
- Incorrectly coding resolved AKI when CKD is present
Coding Notes
- Ensure documentation clearly states resolution of AKI and absence of CKD.
N17.9 - Acute kidney failure, unspecified
Use for active AKI episodes.
Applicable To
- Active acute kidney injury
Excludes
- Resolved AKI (Z87.19)
Clinical Validation Requirements
- Serum creatinine increase ≥0.3 mg/dL in 48h or ≥1.5x baseline
Coding Notes
Ensure KDIGO criteria are met for active AKI coding.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting History of Acute Kidney Injury to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code Z87.19.
Impact
Clinical: Inadequate clinical understanding of patient's history., Regulatory: Potential audit issues due to vague documentation., Financial: Possible reimbursement denials.
Mitigation Strategy
Always document the cause of AKI if known, Include resolution status and baseline labs
Impact
Reimbursement: Incorrect DRG assignment may affect reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate patient records and data reporting.
Mitigation Strategy
Code N18.x for CKD and add Z87.19 for resolved AKI context.
Impact
Coding Z87.19 without proper documentation of AKI resolution.
Mitigation Strategy
Ensure documentation includes baseline creatinine and resolution status.
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.
