Reimbursement: Potential underpayment due to incomplete coding, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate clinical data representation
Mitigation Strategy
Ensure both acute and chronic components are documented and coded.
Impact
Risk of audits due to missing chronic component documentation.
Mitigation Strategy
