Prior Authorization for Replacement of Power Mobility Devices (PMDs) – Effective June 2, 2024
Starting June 2, 2024, CGS will require prior authorization on all replacement PMDs on the Required Prior Authorization List
. This includes lost, stolen, or irreparably damaged items. CGS will deny claims for replacement PMDs with the RA modifier that did not receive prior authorization.

- A physician's Written Order Prior to Delivery (WOPD). The DME MACs require a new order for replacement items.
