Clinical: Inadequate pain management, Regulatory: Non-compliance with documentation standards, Financial: Potential claim denials

Mitigation Strategy

Always assess and document pain level, Use pain scales consistently

Impact

Reimbursement: Incorrect sequencing can lead to claim denials., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate representation of patient's condition.

Mitigation Strategy

Sequence E11.51 → L84 → M79.67-

Impact

Using incorrect modifiers for Medicare claims can lead to audits.

Mitigation Strategy

Ensure documentation supports the use of each modifier.
