Using R34 as a principal diagnosis when AKI is present.

Impact

Reimbursement: Incorrect DRG assignment, potentially lower reimbursement., Compliance: Non-compliance with ICD-10 guidelines., Data Quality: Inaccurate clinical data representation.

Mitigation

Code N17.9 first, R34 as secondary.

AKI Coding

Impact
