Steven Conway, D.C., DABCOH, Esq., is a 1983 graduate of Logan Chiropractic College.  Dr. Conway (along with his father Dr. Richard and his wife Dr. Cindy) successfully provided chiropractic services to Southern Wisconsin. Dr. Conway entered the legal profession in 1996 after graduating from Stetson University, College of Law. He has since combined both legal and chiropractic backgrounds to successfully defend chiropractors with Medicare audits and state board complaints. His work with Medicare has transformed the chiropractic profession.  Together with Dr. Michael Jacklitch, Dr. Conway personally met and worked with the Centers for Medicare and Medicaid Services (CMS) and all Chief Medical Directors of the national Medicare Administrative Contractors (MACs) to update the review process for chiropractic documentation.  His experience with chiropractic Medicare audit defense led to a universal interpretation and subsequent harmonization of review criteria for chiropractic documentation.  Drs. Conway and Jacklitch trained the MAC reviewers on the process creating a level playing field for chiropractic.   They are now training chiropractors across the United States on the new Medicare documentation interpretation.  Doctors of chiropractic are now universally accepting this training and implementing the process learned, providing them the tools to successfully navigate audits.
