Credentialing & Compliance

Delta Dental's Medicare Advantage membership is growing, and your participation in this network is a great opportunity to increase the number of patients choosing your practice as their dental home. If your office is considering joining our Medicare Advantage network or is already participating, you'll need to ensure compliance with the Centers for Medicaid and Medicare Services (CMS) requirements for Medicare Advantage providers. The Compliance Attestation and the information on this page will help you understand what you need to do to adhere to those requirements. If you need any assistance, you can contact our provider relations team at

Offshore Subcontracting Attestation

Contracted Medicare Advantage dental offices that subcontract with any offshore entities to process or have access to protected health information (PHI) are required by CMS to complete this attestation within 10 calendar days from the date a contract is signed or immediately upon knowledge of this requirement.

Exclusion Screening: Office of Inspector General (OIG) List of Excluded Individuals and Entities (LEIE)

OIG's LEIE provides information regarding individuals and entities currently excluded from participation in Medicare, Medicaid, and all other federal health care programs. You should check the list monthly to ensure that new hires and current employees are not on it.

General Services Administration (GSA) or System for Award Management (SAM) List

The GSA similarly maintains several exclusion lists, managed through the System for Award Management (SAM). You should routinely check SAM to ensure that excluded individuals and/or entities are not involved in provision of care services on behalf of your office.

CMS Preclusion List

CMS maintains a list of providers and prescribers who are precluded from receiving payment for Medicare Advantage items or services or Part D drugs furnished or prescribed to Medicare beneficiaries. You will receive an email and a letter from CMS/Medicare Administrative Contractors in advance of your inclusion on the preclusion list. The email and letter will be sent to your Provider Enrollment Chain and Ownership System (PECOS) address or National Plan and Provider Enumeration System (NPPES) mailing. The letter will contain the reason you are precluded, the effective date of your preclusion, and your applicable rights to appeal. Medicare Advantage plans are required to deny payment for a health care item or service furnished by an individual or entity on the preclusion list.
