CMS Pub. 100-08, ch. 10, § 10.3.2.2

A. Correspondence Address and Telephone Number

Regarding the Correspondence Address section of the Form CMS-20134, the

correspondence address must be one where the contractor can directly contact the applicant

to resolve any issues once the supplier is enrolled in Medicare. Although the contractor

need not verify the correspondence address, the latter cannot be the address of a billing

agency, management services organization, chain home office, or the supplier’s

representative (e.g., attorney, financial advisor). It can, however, be a P.O. Box or, in the

case of an individual practitioner, the person’s home address.

Concerning the telephone number in the Correspondence Address section of the Form

CMS-20134, the supplier may list any telephone number it wishes as the correspondence

phone number. The number need not link to the listed correspondence address. If the

supplier fails to list a correspondence telephone number and the latter is required for the

application submission, the contractor shall develop for this information using the

procedures outlined in this chapter (e.g., the PCV for PECOS applications). The contractor

shall accept a particular phone number if it has no reason to suspect that it does not belong

to or is not somehow associated with the supplier. The contractor is not required to verify

the telephone number.

B. E-mail Addresses

An e-mail address listed on the application can be a generic e-mail address. It need not be

that of a specific individual. The contractor may accept a particular e-mail address if it has

no reason to suspect that it does not belong to or is not somehow associated with the

supplier.

Regarding unavoidable phone number or address changes (and unless CMS specifies

otherwise), any change in the supplier’s phone number or address that the supplier did not

cause (e.g., area code change, municipality renames the supplier’s street) must still be

updated via the Form CMS-20134.

C. Supplier Identification Information

Regarding Supplier Identification Information – Business Information, the contractor may

capture all information in the Identifying Information (Business Information) section (with

the exception of the TIN and legal business name (LBN) by telephone, fax, the PCV, e-mail, or a review of the supplier’s Web site.
