What type of audit was performed when a professional was hired to review claims at Dr. Oppenheim's office?

In this scenario, the audit being referred to is classified as an internal audit. An internal audit typically involves a review conducted by professionals within the organization or those hired specifically to evaluate the operations of the organization from a compliance perspective. In the context of Dr. Oppenheim's office, having a professional assess the claims indicates that the review was conducted internally, with the aim of ensuring proper compliance and identifying any areas that may need improvement or correction.

Internal audits are essential for healthcare practices as they help practitioners stay in line with regulatory standards and improve efficiencies. They also serve to prepare for any potential external audits, ensuring that the organization's processes are robust and compliant with necessary regulations. By hiring a professional, Dr. Oppenheim's office demonstrates a commitment to internal quality assurance and adherence to healthcare compliance guidelines.

In contrast to internal audits, external audits would involve outside parties scrutinizing the organization's claims, which is not the case here. Multi-focused audits typically address various areas simultaneously rather than a focused review of claims. Retrospective audits analyze past claims for compliance but don’t necessarily indicate who conducted the audit. Thus, the choice of an internal audit directly reflects the nature of the review being done at Dr. Oppenheim's office.
