Definition:

In case mix classification systems, patients are categorized as typical or atypical based on several criteria. An atypical patient is one where the hospitalization involves a transfer, sign-out against medical advice, ends in death, includes non-acute days, or has a length of stay beyond the trim point (outlier). An atypical patient has a different resource use within the hospital relative to a typical patient. Both the DRG™ and CMG™ patient case mix classification systems distinguish between typical and atypical patients. For more information please see the term typical patient .
