Institutional providers and/or suppliers may want to follow-up on information they

receive, usually to contact the primary agency on file to bill under arrangement. The

provider or supplier may determine the HHA’s A/B MAC (HHH) from the CMS Web

site which has a list of A/B MACs (HHH) that process HH claims by State. The provider

or supplier also may ask its own MAC through existing provider inquiry channels. That

MAC will instruct the provider regarding which A/B MAC (HHH) that processes HH

claims to contact to learn which HHA is involved.

A/B MACs (HHH) that process HH claims may provide information on either the

provider or A/B MAC (HHH) that these providers may request. Information released

will be determined by each MAC, such as HHA name and address, but must be enough

for the inquiring provider/supplier to contact either the primary HHA, if under that A/B

MAC (HHH)’s jurisdiction, or another A/B MAC (HHH), if the provider number is

attached to another A/B MAC (HHH). If an instance ever exists where a provider is an

individual, such as a provider doing business using a Social Security Number as a tax

identification number, information cannot be released, since it would violate the

individual’s right to privacy.
