ICD-10 · PDGM grouping
R70-R79 — Abnormal findings on examination of blood, 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.
Codes in range

No clinical group
45
A period cannot be grouped from these.

CMS rejects these in the primary position.
Where these codes group
None of the 45 codes in R70-R79 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.
