After requesting--then receiving--a contingency plan from the federal government so health insurers can pay claims that don't follow the ANSI X12 version 5010 transaction standards after the January 1 compliance deadline, the Medical Group Management Association is asking for more leniency. The MGMA asked the Centers for Medicare and Medicaid Services to double its grace period to six months, citing new data showing that few physician practices are ready for the change. The organization, which represents group physician practices, issued data from a survey of members showing that just 13.9% of respondents consider their 5010 preparations "fully complete."
