R90-R94 — Abnormal findings on diagnostic imaging and in function studies, without diagnosis
Every ICD-10-CM code in this range and the PDGM clinical group CMS assigns to it, read from the CMS grouper crosswalk v07.2.26.

Where these codes group
None of the 64 codes in R90-R94 is assigned a PDGM clinical group. A 30-day period cannot be grouped from any of them, so none can hold the primary position on a home health claim.
