Due to federal Transparency in Coverage rules, HWMG will be required to publish your Tax ID Number (TIN) and National Provider Identifier (NPI) beginning January 1, 2022. If you use your Social Security Number as your TIN, we will be required to publish it unless you obtain an Employer Identification Number (EIN) from the IRS.
If you apply for an EIN, upon receiving it please submit a Provider Add/Delete Change Form and Form W-9 to HWMG so we can update our systems. If you already have an EIN and have not sent it to us, please do so as soon as possible.
