Online Provider Directory Requirements
110.2.4 – Online Provider Directory Requirements
(Rev. 121, Issued: 04-22-16, Effective: 04-22-16, Implementation: 04-22-16)
MAOs must post a provider directory for all products offered by service areas or by
general geographic area. The provision of accurate provider information and ensuring
adequate access to covered services are essential protections for enrollees. Accurate
provider directories are critical to helping enrollees make educated decisions about their
MA plan choices.
The following formats for the online provider directory are acceptable:
• A searchable “master” provider directory that represents the complete network
for the MAO;
• Individual provider directories by plan product and/or service area (e.g.,
mirroring those that will be printed for the MAO membership); and
• A search engine. If an MAO uses only a search engine on its website, it must meet
all the requirements for the model Directory.
MAOs must also provide the option on their websites for users to request a hard copy
provider directory, as applicable. MAOs are expected to mail the requested hard copy
directory within three (3) business days of the request.
