How Do I Change My Last Name with Medical Staff Services?

If your last name has changed, you must first make this change on all Washington State licenses, your NPI and DEA registration (if applicable).

Once we can verify this has been completed, a name change will be generated within our office and with Cerner.

NOTE: Name changes through Human Resources (for badging, payroll or other employment activities) must be done separately.
