B · Neuro Rehabilitation
One of the twelve PDGM clinical groups. CMS maps 2115 ICD-10-CM codes to it in grouper v07.2.26.
Group B
ICD-10-CM codes
2,115
Across 54 ICD-10-CM ranges, in grouper v07.2.26.
Functional bands
≤34 · 35–52 · 53+
OASIS points for low, medium and high functional impairment in this group.
LUPA thresholds
2 to 5 visits
Across the group’s 36 case-mix codes. Fewer visits than the threshold pays per visit.

What lands a period in this group
The clinical group is set by the principal diagnosis on the claim, and it is one of the five things that decide a 30-day period’s case-mix group, alongside admission source, timing, functional impairment level and comorbidity adjustment. CMS maps 2115 ICD-10-CM codes to Neuro Rehabilitation, spread across 54 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.
