Ensure lab results are reviewed and documented, Use queries to clarify unspecified infections

Using unspecified codes when specific organism is identified

Impact

Reimbursement: May lead to incorrect DRG assignment and affect reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases accuracy of clinical data.

Mitigation

Ensure documentation specifies the organism and use the corresponding specific code.

Organism specificity

Impact

Risk of audits if organism is not specified in documentation

Mitigation

Implement regular training for clinicians on documentation requirements.
