Physician Medical Coding Expertise

Founded by David Zielske (“Dr. Z”), MD, ZHealth Publishing is built on the premise that the best coding expertise comes from skilled physicians who are familiar with both the clinical aspects of these procedures as well as the most current coding rules. Dr. Zielske and ZHealth physicians have performed the procedures discussed in our medical coding books, coding seminars, audio webinars, and eLearning, self-study online courses. Plus, they have had extensive training and expertise in medical coding rules and regulations…and make it their business to be up-to-speed on all the latest developments.
