Georgia HFMA Summer Scroll, Georgia HFMA, 2007 – This is Part 1 of a 2 Part series that discusses the increasingly complex efforts of insurers to manage their exposure to changes in hospital charge masters. What used to be a fairly anonymous line item in a compensation schedule is now two or three pages of protective language that covers everything from allowable increases to adjustment formulas and take-back provisions. While creating adequate explanations of a complex contractual issue is laudable,many of the techniques and provisions contained in such language are mathematically misunderstood and can be slanted in favor of the insurer. With most managed care contracts containing multiple items that are paid as a percentage of billed charges (stop-loss,implants, outpatient default are some common entries), it is now more important than ever that hospitals understand the impact of such language, as well as the perspective from which managed care companies are approaching this important issue., Author, Negotiating Charge Master Protective Language with Managed Care Companies.
