Changes in Ownership:

Changes of Ownership (CHOW) typically occur when a Medicaid provider has been purchased by another organization. If this is a CHOW, please attach the purchase/sale contract and a letter that explains this is a CHOW and includes the old owner’s NPI, Medicaid ID, and effective date of the new ownership.
