Impact
Clinical: Inaccurate treatment plans, Regulatory: Non-compliance with coding standards, Financial: Potential denial of claims
Mitigation
Ensure lab results are reviewed and documented, Query providers for missing information

Impact
Reimbursement: Potential underpayment due to lack of specificity., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate data affecting clinical statistics.
Mitigation

Use of unspecified codes
Impact
High risk of audit if unspecified codes are used without supporting documentation.
Mitigation
Ensure all documentation supports the specificity of the code used.
