Prescription Drug Coverage

If you expect any significant extended health or dental expenses, it is advisable to submit a cost estimate/predetermination to GS to confirm how much you can expect to be reimbursed.

To determine if a specific medication/treatment will be covered by our plan, we advise you to contact GS directly at 1-888-711-1119 or, you can submit a request online with GreenShield +  to check your coverage.

Once you are registered and logged into your member site, select the button “check your coverage” (bottom left screen).

Once selected, you’ll be brought to the following window, and all you need to do is now provide information that is required to see if you are eligible for a service.

If you require any assistance during this process, please contact GreenShield.

For a compound to be eligible with GreenShield, it needs to have the following characteristics:

• Contains an active ingredient in a therapeutic concentration that is considered an eligible benefit
• Is not a duplication of a formulation of a manufactured pharmaceutical product
• Not experimental or cosmetic

GreenShield will guide you through the eligibility of Compound Drugs.

For more information, please review GreenShield's plan member compound policy (PDF).

Prior authorization is a program where certain drugs require pre-approval before payment for the claim is made.

Prior authorization drugs tend to be expensive and/or have the potential to be used inappropriately, either through excessive use or for unapproved medical conditions. For each prior authorization drug, GS establishes medical criteria that you must meet before approval of coverage is granted.

The prior authorization program works for you by ensuring that drugs are taken for the approved medical conditions, treatment follows established guidelines, and that standard first-course drug therapies are tried before second-course treatments are approved. The prior authorization program ensures you receive the best drug options possible.

How to apply for prior authorization

1. Get a Prescription Drug Special Authorization Form and/or the GreenShield Eligible Criteria Sheet for the prescribed drug. There are three ways to do this:

GreenShield along with NKS Assist, have developed a Preferred Pharmacy Network (PPN) to help limit the high cost of specialty drugs for you and your benefits plan and ensures that you get the treatment support you need.

GreenShield’s cross-Canada preferred pharmacy network includes chain pharmacies such as Shoppers Drug Mart, Loblaws, Safeway, Lawton’s Drugs, Sobeys along with NKS Health pharmacies and a few independent pharmacies, mostly in rural or remote areas. Some outpatient pharmacies in select regional cancer centers, which are centers of excellence in the treatment of cancer are also included. In addition, all of the network pharmacies that are part of PPN offer medication delivery to your home or clinic.

The specialty drugs included in the PPN program are available from approved pharmacies at a reduced cost, which may reduce your out-of-pocket expenses. Refer to Preferred Pharmacy Network for further details. 

GreenShield Pharmacy (previously Digital Pharmacy) provides you convenient and affordable access to the medications and pharmacy services you need – from the comfort of your home.

Skip the line to drop off your prescriptions or pick them up – your medications will come to you instead. Plus, you get lower prescription costs and free delivery.

Have a question about your medication? You can call, send an email, or book a virtual appointment – a team of licensed pharmacists is available to answer your questions and provide clinical expertise.

Even better, it’s available to all GreenShield plan members at no additional cost.

For more information, please visit GreenShield’s Pharmacy Services link.

If you must take the brand name version of a drug due to an adverse reaction to the generic version, your pharmacist or physician will complete a Health Canada adverse drug reaction exception form to be submitted to both GreenShield and Health Canada. 

The brand name drug approval form can be found on the Health Canada website or your doctor’s office, or your pharmacy may be able to provide it for you. Once completed by the medical doctor, the original form is sent to Health Canada Vigilance and the manufacturer, and a copy must be sent to GreenShield for assessment.

Contact GreenShield if you have questions regarding this process.

GreenShield along with NKS Assist, have developed a Specialty Care Program, a preferred pharmacy network to help limit the high cost of specialty drugs for you and your benefits plan and ensure that you get the treatment support you need.

The Specialty Care Program offers you…

• Potential savings on any out-of-pocket expenses you may be paying for your medication
• Coordinating any applicable patient assistance programs with your GS plan
• Free delivery of your medication, if applicable, directly to your treatment location or any other address of your choice

• Dispensing of the medication to coordinate with your treatment appointments and communicating with your prescribers if needed

• Adherence support services to help ensure you take your medication as prescribed

Certain drugs require prior authorization from GreenShield before your drug claim can be reimbursed. Further, certain drugs defined by GreenShield as specialty drugs may be required to be purchased from an approved pharmacy that is a member of GreenShield’s Specialty Care Program before your claim can be reimbursed.

You can find out if your drug requires prior authorization or is included in GreenShield’s Specialty Care Program, either by checking your coverage under “Your Health Benefits” on GreenShield + or by contacting GreenShield’s Customer Service Centre.

For those who are newly starting biologic therapy, GreenShield covers only biosimilars (if one exists) and allows originator products only in exceptional circumstances (i.e. the prescriber must submit a clinical rationale for why the plan member is not able to use a biosimilar product).  

If a member receives a prescription for an originator biologic, the pharmacist will advise that there is coverage up to the cost of the biosimilar only (while dispensing the originator biologic); alternatively, they can pursue prior authorization through GreenShield for the originator biologic to determine if exceptional circumstances exist which would allow for full coverage of the originator biologic.   

GreenShield’s biosimilar programs and approaches include a number of high- and low-cost biologic drugs (e.g., Remicade®, Humira®, Enbrel®, Lantus®, etc.) which are used to treat a number of conditions (e.g., rheumatic, dermatologic, inflammatory bowel conditions; diabetes; multiple sclerosis, etc.). The number of drugs and eligible indications will continue to grow over time as more indications for the existing biosimilars are approved and new biosimilars enter the market.

As of January 2025, the following biologics have biosimilars available: 

If you have any questions regarding the biosimilar new start program, please reach out to GreenShield

As announced last fall, the University has amended the extended health benefit to adopt GreenShield’s biosimilar transition program. For those benefit members who are receiving biologic therapy, please be aware that starting April 8, 2025, the extended health benefit will no longer fully reimburse originator drugs where a biosimilar drug which provides comparable health outcomes is available, except in exceptional cases.  

This program impacts a very limited number of benefit members initially, but the program will continue to impact members as new biosimilars enter the market. If you are impacted now or in the future, you will receive a letter of notification from GreenShield detailing the steps you need to take. On January 8, 2025, GreenShield issued 52 personalized notification letters to impacted benefit members via Canada Post, which includes instructions and actions to take in the next three months.  

What is a Biosimilar Drug?

A “biosimilar” is a Health Canada-approved biologic drug that has comparable health outcomes for patients as the originator biologic, but at a significantly lower cost. Unlike conventional generic drug products, which can be interchanged at the pharmacy, a biosimilar is treated like a new drug due to the complicated development and manufacturing process, meaning a new prescription is required.

What this means to benefit members?

To avoid additional out-of-pocket costs, members should work with their prescriber (and NKS Assist where appliable) to transition to the biosimilar drug.  If a member chooses to maintain their prescription for an originator biologic instead of the biosimilar drug, reimbursement through the benefits plan will be limited to the biosimilar cost as of April 8th, with members responsible for the additional cost.If you and your dependents are covered for extended health benefits by more than one plan, you can also explore coordinating your benefits.  

If it's medically necessary to stay on the originator drug, an impacted member’s prescriber can submit a Biosimilar Exception Request Form to GreenShield to determine if exceptional circumstances exist for continued coverage.  If approved, the originator biologic will continue to be covered under the extended health benefit.

We understand that a change in medication may raise questions.  Benefit members who receive the notification letter should speak with their prescriber about the change to a biosimilar drug.

Biologic medications currently in the program:

Initially, this change applies to the following originator biologics where biosimilars with comparable health outcomes are available.

* GreenShield has partnered with NKS Assist to support members with the transition from these originator biologics to ensure there is no disruption in treatment.

Note: This list is not exhaustive.  As new biosimilars are approved by Health Canada, these drugs will be reviewed by GreenShield for the possibility of being added to the program. If a new biosimilar becomes available, impacted members will receive a notification letter that allows for 90 days (3 months) transition time.

Please contact GreenShield with any questions about the biosimilar transition program.
