Vague documentation of asthma severity
Impact
Clinical: Leads to inappropriate treatment plans., Regulatory: Non-compliance with coding standards., Financial: Potential for denied claims.
Mitigation
Use specific terms like 'mild persistent', Include objective measures like PEF
Using unspecified codes when severity is documented
Impact
Reimbursement: May result in lower reimbursement rates., Compliance: Increases risk of audits., Data Quality: Reduces accuracy of clinical data.
Mitigation

Documenting 'history of asthma' for active cases
Impact
Reimbursement: Incorrect coding can affect payment., Compliance: Non-compliance with coding guidelines., Data Quality: Misrepresents patient condition.
Mitigation
Use current asthma codes with appropriate severity.
Use of unspecified codes
Impact
High risk of audit if unspecified codes are used frequently.
Mitigation
Train staff on specific coding requirements.
