Using unspecified codes when specificity is available

Impact

Reimbursement: Potential for lower reimbursement rates, Compliance: Non-compliance with coding guidelines, Data Quality: Decreased accuracy in health data

Mitigation

Document specific details such as severity and laterality.

Asthma Coding Specificity

Impact

Risk of audits due to unspecified asthma coding

Mitigation

Implement regular documentation reviews and training sessions.
