Specific coverage

Infertility services

Comprehensive Infertility services, such as artificial insemination and ovulation induction, as well as Advanced Reproductive Technologies (ART), including in-vitro fertilization (IVF), gamete intra-fallopian transfer (GIFT), zygote intra-fallopian transfer (ZIFT) and frozen embryo transfer (FET), will be covered if obtained at Aetna-designated Institutes of Excellence (IOEs) and pre-certified by calling the National Infertility Unit at 1-800-575-5999.  Coverage for this benefit is subject to a $10,000 lifetime limit for each covered person.  Comprehensive infertility services are limited to six cycles of each per lifetime; charges for these cycles do not count toward the $10,000 lifetime limit.

Dental treatment

Certain dental expenses are covered under the EMMP POS II "A" and "B" options. These include charges by a dentist or oral surgeon for treating fractures or dislocations of the jaw or for treating teeth and surrounding tissue damaged because of an injury sustained. Also covered are certain cutting procedures in the mouth, including:

  • Impacted and unerupted teeth.
  • Removing a tumor.
  • Removing or draining an abcess or cyst.
  • The alveolar process (alveoplasty and vestibuloplasty).
  • Gingivectomy.

Oral surgery and related procedures covered under the POS II plan are reimbursed at 75% for the POS II “A” and 80% for the POS II “B”, regardless of the provider’s network participation.

For a complete list of oral surgery procedures which may also be considered for payment under the ExxonMobil Dental Plan, consult the ExxonMobil Dental Plan SPD. If you incur dental expenses that may be covered under this option, submit your claim to Aetna Member Services.

After determining benefits payable under this option, the claim will be processed as a dental claim (for coordination of benefits) for participants in the ExxonMobil Dental Plan. If you are not a participant in the ExxonMobil Dental Plan, when you receive an explanation of benefits, send the explanation and a copy of your bills along with a claim form to your other dental plan claims office.

Extended-care facilities

An extended-care facility provides skilled-nursing services and rehabilitation care. Extended-care facility charges are covered expenses if these conditions are met:

Reimbursement is based on the facility charge or daily room and board rate of the hospital from which the patient transferred, whichever is less.

Skilled-nursing care

Skilled-nursing care is covered if medically necessary and pre-certified. Nursing care that helps a person meet personal needs and daily living activities, such as bathing, dressing, eating or administering oral medication, even if ordered by a physician and performed by a licensed medical professional, is considered custodial and is not a covered expense eligible for benefits. Also, charges for a private-duty nurse in a hospital or an extended-care facility are not covered.

Skilled care

Skilled care involves nursing or rehabilitation services that can be provided only by licensed medical professionals. For example, intravenous feeding is a skilled service.

Hearing aids

Benefits are provided up to a maximum of $2,500 after the deductible and co-insurance are paid for one or more medically necessary hearing aids every rolling five year period, which also includes the repair of a hearing aid. However, shipping and handling charges and routine maintenance such as battery replacement are not covered. The amount allowed is subject to reasonable and customary limits but not negotiated rates. There are no Medical POS II preferred providers for hearing aids and related materials. The member will be responsible for the difference between the billed and allowable amount regardless of provider participation.

You may be able to maximize your benefit through the Amplifon Hearing Health Care (formerly HearPo) or the Hearing Care Solutions Discount Program. These programs are available to Aetna participants and offer discounts on hearing exams, services and hearing aids. If you go to a participating hearing discount center, your out-of pocket expenses could be lower. To find a participating hearing discount center location, you can visit and search DocFind®, or you can log in to Aetna Navigator® and click on “Find a Doctor, Facility or Pharmacy” and then select “Hearing Discount Locations”. To compare costs, please call Amplifon Hearing Health Care at 1-888-HEARING (1-888-432-7464) or Hearing Care Solutions at 1-866-344-7756 and identify yourself as an Aetna member.

Organ, tissue and bone marrow transplants

Aetna's National Medical Excellence® Program (NME Program) coordinates all aspects of organ, tissue, and bone marrow transplants and other complex specialized care. Providers in this program are recognized as centers of excellence with demonstrated improved outcomes in their area of expertise. In addition, if travel over 100 miles is required, lodging and meals for the patient and a traveling companion will be covered.  The NME Program is separate and distinct from the Centers of Excellence described in the Culture of Health section of this SPD.

The NME Program is available on a voluntary basis. Contact Aetna Member Services for information.

Case management alternative treatment program 

If as a result of a catastrophic or chronic illness or injury or in conjunction with certain organ transplant procedures, a participant proposes an alternative course of treatment, the Administrator-Benefits may waive any exclusion or limitation under the Plan which would otherwise apply to covered medical expenses, the reimbursable portions of covered medical expenses or out of pocket limits if such waiver would result in overall cost savings to the Plan. The review will include factors such as the efficacy of the proposed treatment, the patient's condition, availability and efficacy of other treatments that are approved for the patient's diagnosis, and the prior use of appropriate treatments for the condition. Such approval must be prior to the participant commencing the alternative course of treatment.

Treatment of last resort

In life-threatening situations, experimental or investigational treatment may be considered a covered expense as a treatment of last resort. A person's condition is considered life-threatening if there is a reasonable likelihood that death will result in a matter of months without treatment or that premature death will occur without early treatment. In this case, proposed experimental or investigational treatments will be reviewed by a panel of specialty-matched experts. The review will include factors such as the efficacy of the proposed treatment, the patient's condition, availability and efficacy of other treatments that are approved for the patient's diagnosis, and the prior use of appropriate treatments for the condition.

Treatment of last resort must be authorized by the Administrator-Benefits, and will be based on the fact that the covered person's condition is life-threatening and the treatment is recommended by a panel of specialty-matched physicians chosen to review the treatment.
