Unbiased Philosophy

Tiber Creek Rx approaches the audit process from an unbiased perspective. Sarbanes-Oxley auditor independence standards restrict auditing firms from providing non-audit consulting services for the same clients. Tiber Creek Rx adheres to these standards as we do not provide conflicting consulting services, such as PBM sourcing (RFPs for PBM services). Many consulting firms offering PBM sourcing services are paid fees by the PBMs their clients select. We do not need to generate additional business for a consulting division.

Our objectives remain focused on quality audit results rather than our compensation. Therefore, our fees are never based on contingencies, eliminating any unsupportable and unrecoverable findings that drag-out the audit time-frame and frustrate both our clients and the PBMs.

The Process

Our audit process was developed based on the lessons learned over nine years of auditing PBMs. The approach is engineered to make the process clear and focused, eliminating wasted time for all parties. Tiber Creek Rx works with each client to develop an agreed upon audit scope and time-frame. We tailor the audit to meet the unique needs of each client.

Obtaining accurate information and data is essential to producing a quality audit result. Our auditors do not work in a vacuum; they engage the client and the PBM throughout the process to ensure correct parameters are applied and tested.
