Ensure DXA scan is performed and documented., Exclude secondary causes before coding.

Impact

Reimbursement: Incorrect coding can lead to claim denials., Compliance: May result in non-compliance with coding guidelines., Data Quality: Affects the accuracy of patient records.

Mitigation Strategy

Verify T-score and ensure correct code selection based on clinical criteria.

Impact

High risk of audit if unspecified codes are used without proper documentation.

Mitigation Strategy

Ensure complete documentation of DXA results and exclusion of secondary causes.

Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
