A transplant will be covered only if performed in a facility that has been designated as an IOE facility for the type of transplant in question. Any facility that is not specified as an Institute of Excellence network facility is considered as an out-of-network facility for transplant-related services, even if the facility is considered as a participating facility for other types of services.

Maternity care

The Plan covers physician and hospital care for mother and baby, including prenatal care, delivery and postpartum care. In accordance with the Newborn and Mothers Healthcare Protection Act, you and your newly born child are covered for a minimum of 48 hours of inpatient care following a vaginal delivery (96 hours following a cesarean section). However, your provider may after consulting with you discharge you earlier than 48 hours after a vaginal delivery (96 hours following a cesarean section).

You do not need a referral from your PCP for visits to your participating obstetrician. A list of participating obstetricians can be found in your provider directory or on DocFind® (see Provider Information).

Note: Your participating obstetrician is responsible for obtaining precertification from Aetna for all obstetrical care after your first visit. They must request approval (precertification or referral) for any tests performed outside of their office and for visits to other specialists. Please verify that the necessary referral or precertification has been obtained before receiving such services.

If you are pregnant at the time you join the Plan, you receive coverage for authorized care from participating providers on and after your effective date. There is no waiting period. Coverage for services incurred prior to your effective date with the Plan is your responsibility or that of your previous plan.

Behavioral health

Your mental health/substance abuse benefits will be administered by Magellan Healthcare. The Aetna network is not used for mental health or substance abuse care. Magellan Healthcare provides precertification of inpatient (which may be required) treatment, provider referral, ongoing consultation and review, and case management for mental health and substance abuse treatment. You do not need a referral from your PCP to obtain care from participating mental health and substance abuse providers. Instead, when you need mental health or substance abuse treatment, call the Magellan Healthcare telephone number shown on your ID card. A clinical care manager will assess your situation and refer you to participating providers, as needed.

  • Inpatient medical, nursing, counseling and therapeutic services in a hospital or non-hospital residential facility, appropriately licensed by the Department of Health or its equivalent.

The Aetna Select option includes a number of provisions specific to mental health and substance abuse treatment. When determining whether a service or supply is medically necessary, Magellan utilizes written medical necessity criteria. Those criteria are available upon request, consistent with applicable law. You and your providers may contact Magellan at 800-442-4123 to request the medical necessity criteria applicable to a treatment or visit their website at Magellan Ascend.

Prescription drugs

The Plan pays, subject to any limitations specified under Your Benefits, the cost incurred for outpatient prescription drugs that are obtained from a participating pharmacy. Express Scripts is the pharmacy benefit manager for your prescription drugs.  You must present your Express Scripts or Medco ID card and make the copayment shown in the Benefits summary for each prescription at the time the prescription is dispensed.

The Plan covers the costs of prescription drugs, in excess of the copayment, that are:

  • Medically necessary for the care and treatment of an illness or injury, as determined by Express Scripts;
  • Prescribed in writing by a physician who is licensed to prescribe federal legend prescription drugs or medicines, and
  • Not listed under Prescription Drug Exclusions and Limitations, below.

Non-emergency prescriptions must be filled at a participating pharmacy. Generic drugs may be substituted for brand-name products where permitted by law.

Coverage is based upon Express Scripts’ formulary. A formulary is a list of commonly prescribed medications within particular therapeutic categories. The drugs on the list have been selected based on their effectiveness and cost. To be included in the formulary list, a drug must meet rigorous standards of approval by the Express Scripts Pharmacy and Therapeutic Committee — a group of nationally recognized medical professionals. The formulary includes both brand-name and generic drugs and is designed to provide access to quality, affordable outpatient prescription drug benefits. You can reduce your copayment by using a covered generic or brand-name drug that appears on the formulary. Your copayment will be highest if your physician prescribes a covered drug that does not appear on the formulary. It is always up to your doctor to decide which medications to prescribe. If you have questions about the Express Scripts formulary, you should contact Express Scripts directly.

Long-term or maintenance medications

A long-term or maintenance medication is a drug you take for an extended period of time, such as for the ongoing treatment of diabetes, arthritis, a heart condition, or blood pressure. After the third short-term fill of a maintenance medication, subsequent refills must be purchased as a 90-day supply at a Smart90 retail pharmacy (Walgreens, CVS) or Express Scripts home delivery pharmacy. If you continue to purchase short-term fills of a long-term or maintenance medication after the third fill, you will be responsible for 100% of the cost.

You may order refills by calling Express Scripts or sending in the refill label provided with your previous order. You may also order refills through Express Scripts’ website. You should order a refill about three weeks before your current supply will be exhausted, but remember that you must have generally used 75% of the previous prescription based on the prescribed dosage. During natural disasters, you may be able to replace lost or damaged medications without having used 75% of the previous prescription.

Specialty medications

Specialty medications, including injectables and infusions for rheumatoid arthritis and other inflammatory conditions, require special handling and may be administered in a hospital, clinic, doctor’s office, or in your home. Some specialty medications, like most oncology drugs administered in a hospital setting, are covered under the medical benefit administered by Aetna. Other specialty medications are covered under the prescription drug program administered by Express Scripts. If you have questions about starting a specialty medication, call Aetna member services and ask to speak to a Health Advocate nurse.

Specialty medications administered by Express Scripts are filled through their specialty pharmacy, Accredo, and can be delivered to hospitals, clinics, doctor’s offices, or to a home health care provider. Although the percentage copayments and maximum per prescription for specialty drugs are generally the same as for brand name drugs, higher copayments may be charged for certain preferred specialty medications determined to be non-essential health benefits. However, many of these medications may be available at no cost when purchased through the Plan’s copay assistance program. If the specialty medication being purchased qualifies for copay assistance, you will be contacted by a pharmacist from the Accredo specialty pharmacy and asked to enroll in the program. If you choose not to enroll in the program, you will be responsible for the higher copayment.

Emergency prescriptions

You may not have access to a participating pharmacy in an emergency or urgent care situation, or if you are traveling outside of the Plan’s service area. If you must have a prescription filled in such situations, the Plan will reimburse you as follows:

Advanced Utilization Management (AUM)

In some cases, you may be required to try one or more specified drugs to treat a particular medical condition before the Plan will cover another (usually more expensive) drug. Prior authorization and preferred drug step therapy rules are designed to encourage the use of effective, lower-cost drugs.

As part of Express Scripts’ Advanced Utilization Management (AUM) program, certain drugs will not be covered unless pre-certified by Express Scripts, based on medical evidence submitted by your physician. In addition, some therapies will be monitored for appropriate pharmacogenomic parameters, and oral oncology medications will be limited to ensure appropriate use.  Please visit to obtain more information about your medications and if they require a coverage review. If you have a question regarding a drug on the AUM program list, contact Express Scripts at the number listed in the Information Sources section of this SPD.

Preferred drug step therapy rules

Preferred drug step therapy rules are used for certain therapeutic classes of drugs, to encourage the use of effective, lower-cost drugs by initially excluding some targeted medications from coverage, unless prior authorization is provided by Express Scripts. Therapeutic classes include: proton pump inhibitors, sleep agents, depression, osteoporosis, respiratory, cardiovascular, triptans, glaucoma, diabetes, respiratory allergy/asthma, anti-inflammatory and rheumatoid arthritis, growth hormone, stimulants for Attention Deficit Hyperactivity Disorder (ADHD), prostate therapy drugs, topical steroids, and stroke prevention. Non-targeted drugs will be covered without such authorization and will continue to be dispensed with no further action by either you or the prescribing physician. If you have a question regarding a drug in any of these therapeutic classes, contact Express Scripts to determine whether your drug is covered. You will be notified directly by Express Scripts if you are affected by these rules.

Prior authorization rules

Prior authorization rules apply to certain therapeutic classes of drugs; therapies in this section will be monitored for appropriate use, including pharmacogenomics parameters in some cases.  These classes include miscellaneous immunological agents, central nervous system/miscellaneous neurological therapy, biotechnology/adjunctive cancer therapy, central nervous system/headache therapy, central nervous system/analgesics, neurology/miscellaneous psychotherapeutic agents, and miscellaneous pulmonary agents. In addition, anabolic steroids, high cost antibiotics, anti-emetics, antivirals, narcotics, acne dermatologicals and topical pain medications may trigger a prior authorization.  Oral oncology medications will also be limited to ensure appropriate use. Certain drugs within each classes as determined by Express Scripts will only be covered to the extent they are authorized by Express Scripts. If you have a question regarding coverage for a drug in any of these therapeutic classes, contact Express Scripts. You will be notified directly by Express Scripts if you are affected by these rules. 

Split-fill program

Express Scripts’ split fill program applies to certain select specialty conditions where participants often stop or change therapy early in treatment due to side effects or their ability to tolerate treatment. This program will provide smaller initial fills (15-day supply) and clinical support to participants as they begin their therapy. Coinsurance and the per prescription maximum will be applied on a prorated basis so that the participant will not be disadvantaged financially. This program is designed to help manage side-effects, eliminate wasted medications and manage specialty drug costs.

Therapeutic Resource Center

Plan participants and their physicians may receive outreach calls from Express Scripts Therapeutic Resource Center (TRC) pharmacists or healthcare specialists to offer personal over-the-phone guidance as well as other health management tools. You can also ask to speak to a TRC pharmacy specialist when you call Express Scripts.
