List of key terms in the ExxonMobil Employee Medical Plan - POS II A and POS II B options

Barred employee

An employee who is covered by a collective bargaining agreement except to the extent participation is provided under such agreement.


The person or entity that receives benefits when you die. The Plan provides a standard list of beneficiaries but you may name another beneficiary if you wish.

Benefit service

Generally, all the time from the first day of employment until you leave the company's employment. Excluded are:

  • Unauthorized absences,
  • Leaves of absence of over 30 days (except military leaves or leave under the Federal Family and Medical Leave Act),
  • Certain absences from which you do not return,
  • Periods when you work as a non-regular employee, as a special agreement person, in a service station, car wash, or car-care center operations, or
  • When you are covered by a contract that requires the company to contribute to a different benefit program, unless a special authorization credits the service.

Benefit predetermination

The review of proposed treatment or services before the expense is incurred to determine if, and to what extent, charges will be covered by the Plan. 

Case management

Review provided by medical professionals who consult with the patient and/or care providers to determine effective, cost-efficient ways to treat illnesses and utilize plan benefits.

Change in status

Life or work event that allows you to make changes to your elections during the plan year and outside of annual enrollment.


A person under age 26 who is:

  • A natural or legally adopted child of an employee,
  • A grandchild, niece, nephew, cousin, or other child related by blood or marriage to an employee, or the spouse of an employee (separately or together) is the sole court appointed legal guardian or sole managing conservator,
  • A child for whom the employee has assumed a legal obligation for support immediately prior to the child's adoption by the employee or,
  • A stepchild of an employee.

Child does not include a foster child.

Claims administrator / processor 

Aetna Life Insurance Company, or affiliates, for claims other than outpatient prescription drugs, and Express Scripts for retail and home delivery of outpatient prescription drugs.

Copayments and coinsurance

Your share of covered services (including out-patient prescription drugs) and mental health and substance abuse expenses. For some services, such as hospital stays, the coinsurance will be a percentage of the cost of the service once the deductible has been satisfied. For other services, such as office visits to a POS II provider, the copayment will be a fixed amount. For outpatient prescription drugs there is a percentage copayment up to a per-prescription maximum.

Covered medical expense

  • For treatment of injury or sickness — a medically necessary expense incurred by a covered person that is not excluded from coverage, and
  • For treatment of mental health or substance abuse — a medically necessary expense that is certified in advance of actual treatment or an out-of-network inpatient treatment, that is provided according to the terms of the Plan, and that is not otherwise excluded from coverage.

Covered person 

Any person identified on the books of the employer as an employee, extended part-time employee, eligible family member, or survivor who:

  • Complies with the established enrollment requirements and makes any required contributions, and
  • Is not eligible for any other medical plan to which ExxonMobil contributes on their behalf.

Custodial care

Care that helps meet personal needs and daily living activities. Such care, even if ordered by a doctor and performed by a licensed medical professional such as a nurse, is not covered by the Plan.


The amount of covered expenses you must pay each calendar year before the Plan begins sharing the cost. Fixed amount copayments do not apply toward this amount. Outpatient prescription drug copayments are not subject to nor do they count toward the annual deductible. The deductible is applied to your claims in the order Aetna processes them, not when the provider collects the money from you. This means if you pay your deductible to one provider, it may not be applied to your annual deductible if Aetna has received and processed other claims first. Please be sure to always get an itemized bill and retain proof of your payment, should you need to recover money from your provider.

Eligible employees

Most U.S. dollar-paid employees of Exxon Mobil Corporation and participating affiliates are eligible. The person must be classified on the employer's books and records as an employee.

The following are not eligible to participate in the Plan: leased employees as defined in the Internal Revenue Code, 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:

  • Spouse,
  • 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:
    (a) meets the Internal Revenue Service's definition of a dependent, and
    (b) 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    
    (c) 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 paragraphs two (2) above, ceases to be an eligible family member 60 days following the date on which the applicable requirement is not met.

Please note: An eligible employee'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.

Experimental or investigational

A medical treatment or procedure, or a drug, device, or biological product, is experimental or investigational if any of the following apply:

  • The drug, device, or biological product cannot be lawfully marketed without approval of the U.S. Food and Drug Administration (FDA), and approval for marketing has not been given at the time it is furnished; [Note: Approval means all forms of acceptance by the FDA].

Reliable evidence shall mean only:
  • Peer reviewed, published reports and articles in the authoritative medical and scientific literature,
  • The written protocol or protocols used by the treating facility or the protocol(s) of another facility studying substantially the same drug, device, or biological product or medical treatment or procedure, or

CPBs are based on objective, credible sources, such as the scientific literature, guidelines, consensus statements and expert opinions. These CPBs may be found on the Aetna website at

Medical pre-certification 

Certification obtained prior to a hospital inpatient stay (including mental health and substance abuse) to give notice of inpatient admission and the proposed care. If you do not pre-certify a non-POS II provider or non-Mental Health PPO hospital stay, you will be responsible for the first $500 of eligible expenses. Refer to the Aetna National Precertification list for details of services requiring precertification.

Out-of-pocket limit 

The amount of covered medical expenses you pay in one year before the Plan begins paying 100%. The EMMP POS II A and B options have different out-of-pocket limits. The out-of-pocket limit is accumulated in the order Aetna processes the claims. After the out-of-pocket limit is reached, the Plan pays 100% of most covered expenses for the remainder of that  Calendar year. Certain expenses that you pay do not apply to the out-of-pocket limit. The annual deductible and your percentage copayments for eligible expenses apply to the out-of-pocket limit. The following charges do not apply to the out-of-pocket limit:

  • Charges above reasonable and customary limits.
  • Charges not covered by the Plan.

  • Charges for a private hospital room above the cost of the hospital's most common rate for a semiprivate room.

Outpatient prescription drug

Primary Care Physician means a Physician engaged in general practice, family practice, internal medicine, pediatrics or obstetrics/gynecology who provides basic health services to covered persons.


A written pre-determination request will result in a detailed response as to whether a treatment or service is covered under the 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.

Primary participant 

The term primary participant refers to the participant whose identification number is used. The primary participant is the employee, retiree, survivor or an individual who elected COBRA coverage. Covered family members use the primary participant's identification number to access all medical benefits.

Private duty nursing

Continuous, substantial and complex in-home nursing care requiring services that can only be provided by a licensed medical professional, has been prescribed by a treating physician, provided on an hourly basis and is determined to be medically necessary. Private duty nursing provides more individual and continuous skilled care than the care that can be provided in a skilled nurse visit through a home health agency.

Qualified Medical Child Support Order

Reasonable and customary limits

Aetna’s network is based on a percentage of the Medicare allowable rate or on reasonable & customary limits for the geographical area as determined by Aetna.

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.

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


An employee who is classified as a non-regular employee, but who has been characterized as a Trainee and has graduated from high school.  This definition does not apply to individuals not on the U.S. payroll who are in the U.S. on a trainee assignment and are not on an expatriate assignment into the U.S. 

Urgent care 

Conditions or services that are non-preventative or non-routine and needed in order to prevent the serious deterioration of a person's health following an unforeseen illness, injury or condition.
