Credentialing in managed care.

Through the use of managed care techniques in recent years, the insurance industry has tried to bring the runaway costs of medical care under control. The result of this control effort is system access limitations, compared to the full choice indemnity plans of the past. This limited system access has now clearly moved HMOs and other managed care organizations into the category of "potentially liable health care entities," based on patient steerage, economic disincentives, and limited choices of the plan's participating providers and facilities. Just as hospitals have had to exercise rigorous care in the credentialing of members of their medical staffs, managed care organizations will have to ensure that the providers they use meet acceptable standards of competence.
