Covered charges 

Charges by a dentist or physician for services and supplies required for dental care and treatment. Charges in excess of the reasonable and customary charge made for similar services and supplies by dentists or physicians in the same area are not covered. Where alternative services or supplies are customarily available for such treatment, reimbursement will be based on the least expensive service or supply resulting in professionally adequate treatment.

Eligible employees

Most U.S. dollar-paid employees of ExxonMobil and participating affiliates are eligible. Full-time employees not hired on a temporary basis (also called regular employees) are eligible.

The following are not eligible to participate in the Plan: leased employees as defined in the Internal Revenue Code, barred employees, or special agreement persons as defined in the Plan document. Generally, special-agreement persons are persons paid by the company on a commission basis, persons working for an unaffiliated company that provides services to the company, and persons working for the company pursuant to a contract that excludes coverage of benefits.

Eligible family members 

Eligible family members are generally your:

  • Your spouse. When you enroll your spouse for coverage, you may be required to provide proof that you are legally married. 
  • A child who is described in any one of the following paragraphs (1) through (3):
    1. has not reached the end of the month during which age 26 is attained, or
    2. is totally and continuously disabled and incapable of self-sustaining employment by reason of mental or physical disability, provided the child:
      • meets the Internal Revenue Service's definition of a dependent, and
      • was covered as an eligible family member under this Plan immediately prior to age 26 when the child's eligibility would have otherwise ceased, and
      • met the clinical definition of totally and continuously disabled before age 26 and continues to meet the clinical definition through subsequent periodic reassessment reviews, or
    3. is recognized under a qualified medical child support order as having a right to coverage under this Plan.

A child aged 26 or over who was disabled but who no longer meets the requirements of paragraph two (2) above, ceases to be an eligible family member at the end of the month in which the applicable requirement is not met

Please note: An eligible employee or retiree's parents are not eligible to be covered.

Expatriate employees

Expatriate employees include service-oriented employees employed by non-U.S., non-participating employers who are temporarily working in the United States either under a visa that requires coverage by an ExxonMobil plan of such employee while in the United States or in an assignment in the United States and the terms of the assignment require proof of adequate medical coverage. Expatriate employees include regular employees working on an assignment outside the United States where the terms of the assignment require proof of adequate medical coverage.

Medically necessary

A service or supply that is:

  • Legal,
  • Ordered by a dentist or physician,
  • Reasonably required for the treatment or management of the condition for which it is ordered, and
  • Commonly and customarily recognized by the United States dental community as appropriate in the treatment or management of the condition for which it is ordered. The Administrator-Benefits has the exclusive and final authority to determine if a service or supply is medically necessary as used in the Plan. In making this determination, the findings and assessments of the United States dental community and the experience and expertise of the claims administrator shall be considered along with evaluation from independent professionals. As used herein, the United States dental community shall include national dental associations, societies and organizations including, but not limited to, the American Dental Association. The Administrator-Benefits may apply different standards to different services or supplies in determining medical necessity. Additionally, the Administrator-Benefits may consider the Dental Clinical Policy Bulletins (CPBs) published by Aetna, the claims administrator. Dental CPBs are based on established, nationally accepted governmental and/or professional society recommendations, as well as other recognized sources. These Dental CPBs may be found on the Aetna website at


A written pre-determination request will result in a detailed response as to whether a treatment or service is covered under the Dental Plan and whether the proposed cost is within reasonable and customary limits, thus ensuring all parties are aware of the financial consequences, providing all circumstances described in the request remain unchanged. Please note that a pre-determination, either verbal or written, is not a guarantee of payment, as claims are paid based on the actual services rendered and in accordance with Plan provisions.

Qualified Medical Child Support Order 

A Qualified Medical Child Support Order (QMCSO) is a court decree under which a court order mandates health coverage for a child. A QMCSO must include, at a minimum:

  • Name and address of the employee covered by the health plan.
  • The name and address of each child for whom coverage is mandated.
  • A reasonable description for the coverage to be provided.
  • The time period of coverage.
  • The name of each health plan to which the order applies.

You may obtain, without charge, a copy of the Plan's procedures governing QMCSO determinations by written request to the Administrator-Benefits.

Regular employee

An employee of a participating employer, whether or not the person is a director, who, as determined by the participating employer, regularly works a full-time schedule, and is not employed on a temporary basis.  The definition includes a person who regularly works a full-time schedule but who, for a limited period of time, is approved for a part-time regular work arrangement under the participating employer’s work rules relating to part-time work for regular employees.


Generally, a person at least 55 years old who retires as a regular employee with 15 or more years of benefit  service and who has not thereafter recommenced employment as a covered employee or a non-regular employee. Retiree status may also be attained by someone who is retired by the company and entitled to long-term disability benefits under the ExxonMobil Disability Plan after 15 or more years of benefit service, regardless of age.

Employees who terminate while non-regular are not eligible for retiree status regardless of age or service.

Special-agreement person

Spouse; marriage

All references to marriage shall mean a marriage that is legally recognized under the laws of the state or other jurisdiction in which the marriage takes place, consistent with U.S. federal tax law. All references to a spouse or a married person shall refer to individuals who have such a marriage.

Survivor/surviving spouse

A surviving unmarried spouse or child of a deceased ExxonMobil regular employee or retiree.

Suspended retiree

A person who becomes a retiree due to incapacity within the meaning of the ExxonMobil Disability Plan and who begins long-term disability benefits under that plan, but whose benefits stop because the person is no longer incapacitated. A person remains a suspended retiree until the earlier of the date the person:

  • Reaches age 55, or
  • Begins his or her retirement benefit under the ExxonMobil Pension Plan, at which time the person is again considered a retiree.

The family members of a deceased suspended retiree will be eligible for coverage under this Plan only after the occurrence of the earlier of the following:

  • The date the suspended retiree would have attained age 55, or
  • The date a survivor begins receiving a benefit due to the suspended retiree's accrued benefit from the ExxonMobil Pension Plan.
