Jeffery Majchrzak, BA, CIRCC, RCC, Vice President of Radiology Services for ZHealth Publishing
Jeffery Majchrzak has spent more than 30 years in the healthcare consulting, publishing, education, and training space (including both live seminars and webcast). Jeff served as the primary author and was instrumental in the creation of, as well as annual updating of, numerous publications for services such as interventional radiology, nuclear medicine, PET, CT, MR, ultrasound, general radiology plus cardiac catheterization, as well as other non-invasive vascular services.

From a consulting perspective, Jeff has helped more than 400 clients on both the physician and hospital side to understand the need of complete, compliant dictation and documentation to support appropriate reimbursement for services rendered. Jeff prides himself on being able to draw upon his clinical experience to take complex, payer requirements, marry them to the actual clinical procedures, and distill them to an easier, less intimidating set of instructions and guidelines for facilities and practices.

Prior to embarking on his consulting and publications journey, Jeff worked in both public and private hospitals as a radiologic technologist and department director for nuclear medicine services.
