558. Why Your Claims Are Being Denied: Common Coding Errors

Would you rather read the transcript? Click here. In this episode, I break down the essential components of the “core stack” for psychological and neuropsychological testing billing. Many clinicians leave significant revenue on the table by skipping the diagnostic interview code or miscategorizing professional integration time as simple test administration. I explain the critical differences between the 60-minute professional work codes and the 30-minute administration codes, while highlighting the “half plus one” rule that can legitimately maximize your reimbursement. We also touch on specialized codes for developmental and neurobehavioral screens and the absolute necessity of maintaining an audit-ready log to protect your practice.
