Coding from unsigned lab reports
Impact
Reimbursement: Claims may be denied if unsupported by signed documentation., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate data representation in patient records.
Mitigation
Ensure provider attestation and clinical significance are documented.
Unsupported abnormal lab findings
Impact
Coding without physician documentation increases audit risk.
Mitigation
Ensure all lab findings are documented with clinical significance.
