Codes in range

No clinical group

A period cannot be grouped from these.

Barred as primary

0

CMS rejects these in the primary position.

Where these codes group

None of the 26 codes in R20-R23 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.
