What lands a period in this group

The clinical group is set by the diagnosis reported in the primary position, and it is one of the five things that decide a 30-day period’s payment group — alongside admission source, timing, functional impairment level and comorbidity adjustment. CMS maps 855 ICD-10-CM codes to Behavioral Health, spread across 14 ICD-10-CM ranges.

Those ranges are not always the ones you would expect from the chapter. Cerebrovascular disease sits in the circulatory chapter alongside heart failure, but CMS groups strokes as neurological rehabilitation — which is why the chapter a code lives in is a poor guide to how it pays.

Functional impairment thresholds for Behavioral Health

The same OASIS point total means different things in different groups. In this group a patient scoring 31 or fewer points is low functional impairment, 32 to 46 is medium, and 47 or more is high. CMS sets the bands so roughly a third of periods in each group land in each level, which is why the same documentation can produce a different level in a different group.
