Pharmacy & Formulary

EHP provides prescription drug benefits for several EHP employer groups. However, these benefits may not be applicable to certain employers. Please refer to your patient’s schedule of benefits for detailed information about employer coverage.

Pharmacy Formulary

The EHP Formulary, called the Advanced Control Formulary (effective 01/01/2023), is a useful reference and informational tool. It can assist practitioners in selecting clinically appropriate and cost-effective products for their patients. The formulary is updated on a quarterly basis or as needed and when a new generic or brand-name medication becomes available, and as discontinued drugs are removed from the marketplace.

If a formulary medication is not appropriate, medical necessity prior authorization may be obtained. To do this, you may submit a prior authorization request along with clinical documentation, including treatment failure of covered drugs. Without a prior authorization for medical necessity, the member may be required to pay the full cost of the medication.

The EHP Advanced Control Formulary is subject to change at any time. The formulary is updated on a regular basis, including when new generic or brand-name medications become available and as discontinued drugs are removed from the marketplace. You can review additions/removals to the Advanced Control Formulary:

See if the medication is subject to Utilization Management edits (prior authorization, quantity limit, or step therapy). Registration is required for first-time use.

Prior Authorization

Certain medications require prior authorization before coverage is approved to assure medical necessity, clinical appropriateness, and/or cost effectiveness. Coverage of these drugs is subject to specific criteria approved by physicians and pharmacists on the Pharmacy and Therapeutics Committee. Established criteria are based on medical literature, physician expert opinion, and Food and Drug Administration (FDA) approved labeling information.

Providers may request prior authorization electronically or by calling CVS/caremark's Prior Authorization department at 1-800-294-5979.

Quantity Limits

Certain prescription medications have specific dispensing limitations for quantity and maximum dose. These dispensing limitations are based on generally accepted guidelines, drug label information approved by the FDA, current medical literature, and input from a committee of physicians and pharmacists.

The three types of quantity limits include the following:

Coverage limited to one dose per day for drugs that are approved for once daily dosing
Coverage limited to specific number of units over a defined time frame
Coverage limited to approve maximum daily dosage

When medically necessary, an exception to quantity limits can be requested. If your patient's medical condition warrants use of quantities greater than listed quantities for each drug, you may request prior authorization for a higher quantity. Providers may request prior authorization electronically or by calling CVS/caremark's Prior Authorization department at 1-800-294-5979.

Step Therapy

Certain covered medications are required to satisfy specific step therapy criteria. Step therapy criteria simply means that for certain drug products, members must first have tried one or more prerequisite medications to treat their condition before other medications are covered through their benefit.

When medically necessary, providers may request an exception to the step therapy requirement and ask for prior authorization. Providers may request prior authorization electronically or by calling CVS/caremark's Prior Authorization department at 1-800-294-5979.

Printed copies of EHP's pharmaceutical management procedures are available to providers upon request. Please call (888) 819-1043 and select option 4 to request this information.

Copay Tiers

EHP members covered by the EHP pharmacy benefit have a three-tier drug benefit. Each tier has a different copay or out-of-pocket expense. The EHP Advanced Control Formulary™ consists of the following tiers:

Tier One: Generic
Generic drugs have the lowest out-of-pocket cost for members and are usually placed on Tier 1. Generic products are displayed in the formulary in lowercase italics.
Tier Two: Preferred Brand
Preferred brand-name drugs have a significant safety or efficacy advantage compared to similar agents. These agents have an intermediate out-of-pocket cost for members. These products are usually placed on Tier 2 and displayed in the formulary in CAPS.
Tier Three: Non-preferred Brand
Non-preferred brand-name drugs do not have a significant, clinical advantage in terms of effectiveness, safety, and clinical outcomes compared to similar agents. These drugs have higher out-of-pocket cost for members. In most cases, there will be Tier 1 or Tier 2 alternatives for products found in this tier. Non-preferred brand-name drugs covered under the pharmacy benefit are not displayed in the formulary and may process in Tier 3.

If a member or a provider requests a brand-name drug for which a generic equivalent is available, the member may pay the Tier 3 copay plus the difference between the brand and generic cost.

Retail Pharmacy Network

The retail pharmacy network includes over 64,000 pharmacies nationwide. The network includes most chain retailers and independent pharmacies. Search for a participating network pharmacy.

Generic Substitution

EHP encourages the use and prescribing of generic medications. If the prescriber or member chooses a brand-name drug with a generic equivalent, the member may be required to pay a higher cost share. Cost share for members covered under the EHP pharmacy benefit vary by employer plan design. Cost share for brand-name drugs with a generic equivalent available is determined by the employer's Summary Plan Description (SPD).

Drug Safety Information

Pharmacy Compounded Drugs

To ensure safety and effectiveness of compound drug claims and to manage cost, some compound medications, when rejected at the pharmacy, may require prior authorization. Providers may request prior authorization electronically or by calling CVS/caremark's Prior Authorization department at 1-800-294-5979. The provider must provide clinical documentation to support the request and demonstrate that an FDA approved commercially-available product is not clinically appropriate for the member.

Specialty Medications

Specialty medications are usually high-cost prescription medications used to treat complex chronic conditions. These drugs typically require special storage and handling, and may not be readily available at a local pharmacy. Specialty medications may also have side effects that require pharmacist and/or provider monitoring.

Specialty Medications - Pharmacy Benefit These medications are self-administered and processed through a member’s pharmacy benefit. These medications are available at a local retail or specialty pharmacy and may require prior authorization. Providers may request prior authorization electronically or by calling CVS Caremark's Prior Authorization department at 1-800-294-5979.

Specialty Medications – Medical Benefit These medications are administered by a provider or under supervision of a provider and processed through a member’s medical benefit. Providers may supply these medications and bill the health plan for the medication and related administration using HCPCS Codes or J codes.

View the HCPCS Codes that require prior authorization for medical necessity, and the criteria for these medications.

Note: Johns Hopkins University EHP members are not subject to these prior authorization requirements.
