CMS is seeking comments on new forms it intends to require suppliers to use to report changes of ownership (CHOW) involving contract suppliers under the Medicare durable medical equipment, prosthetics, orthotics and supplies (DMEPOS) competitive bidding program. CMS will evaluate the information in the forms to determine if a supplier that merges with or acquires a contract supplier meets the conditions for awarding a competitive bidding contract as specified in regulations. The proposed Change of Ownership Purchaser Form and Contract Supplier Notification Form will be used in all rounds of competition. CMS will accept comments on the forms through April 30, 2013.
