Failure to document underlying cause.

Impact

Clinical: Misleading clinical picture., Regulatory: Non-compliance with coding standards., Financial: Potential for incorrect billing.

Impact

Reimbursement: Incorrect DRG assignment leading to potential revenue loss., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.

Mitigation

Query for clarification and use N17.9 if tubular necrosis is confirmed.

Incorrect code sequencing

Impact

Improper sequencing of primary and secondary codes.

Mitigation

Educate coders on correct sequencing rules.
