His clients have successfully helped recover hundreds of millions of dollars at the state and federal level.

Highly sought after for his subject matter knowledge, Tim is a frequent author and speaker on issues related to health care reimbursement and coding, provider contracting, commercial and government managed care programs (including Medicare Advantage risk adjustment fraud), the Stark and Anti-Kickback laws, and the use of data and analytics in the detection and remediation of fraud. He is a pioneer in identifying fraud in the Medicare Managed Care/Medicare Advantage program involving upcoding of patient diagnoses in the risk adjustment/risk scoring program.
