Generally Accepted Standards of Medical Practice are standards that are based on credible scientific evidence published in peer-reviewed medical literature generally recognized by the relevant medical community, relying primarily on controlled clinical trials, or, if not available, observational studies from more than one institution that suggest a causal relationship between the service or treatment and health outcomes. If no credible scientific evidence is available, then standards that are based on Physician specialty society recommendations or professional standards of care may be considered. We reserve the right to consult expert opinion in determining whether health care services are Medically Necessary. The decision to apply Physician specialty society recommendations, the choice of expert, and the determination of when to use any such expert opinion will be within our sole discretion. UnitedHealthcare Clinical Services develops and maintains clinical policies that describe the Generally Accepted Standards of Medical Practice scientific evidence, prevailing medical standards, and clinical guidelines supporting our determinations regarding specific services. These clinical policies (as developed by UnitedHealthcare Clinical Services and revised from time to time), are available to Covered Persons by calling UMR at the telephone number on the Plan ID card, and to Physicians and other health care professionals on UnitedHealthcareOnline.com.
