Your Rx benefit


How it works | Costs | Express Scripts

CHPW Individual & Family Plans cover prescription drugs based on medical science and the needs of our members. We manage this benefit for you with the help of our pharmacy benefit partner, Express Scripts.

How it works

✔ To get the most out of your Prescription Drug Coverage benefit, fill your prescriptions at an in-network pharmacy.

✔ After you’ve paid your share of the cost, we pay the pharmacy the rest if:

  • The pharmacy is in-network
  • Covered by your plan
  • Prescribed and medically necessary
  • Prior authorization is approved if required*

*If you have an urgent medical need, based on what your pharmacy provider decides, an Emergency Fill up to one 30-day supply may be covered with cost-shares from an in-network pharmacy. See your plan’s Evidence of Coverage for details.

Reimbursement

If you paid full price for a prescription at an in-network pharmacy, you can ask to be paid back (reimbursement) if you find out it can be covered.

To request reimbursement, contact our benefit manager, Express Scripts online or by mail and submit a Prescription Reimbursement Claim Form.

Tip: Before you ask to be reimbursed, check the drug list (formulary) to make sure there are no restrictions on your medication.

How do I request reimbursement for OTC?

You will need to request reimbursement by fax or mail using different forms if you paid:

Out-of-pocket for OTC birth control (contraceptives)

A cost-share for a prescribed OTC preventive medication

For more information about your plan’s benefits, review your Evidence of Coverage (EOC) and drug list (formulary). If you have questions or need a printed copy of a plan document, call us at 1-866-907-1906 (TTY:711), from 8 a.m. to 5 p.m., Monday through Friday, or email [email protected].

Costs

Your cost for prescription medication depends on your plan and the type of drug or tier (Generic, Preferred Brand, Non-Preferred Brand, Specialty). Find cost-share details in your plan’s Schedule of Benefits or the drug list (formulary).

Tip: Ask your provider or pharmacist about generic options for your medication, for the lowest cost.

To only see plan documents for your specific plan, login to your myCHPW member portal.

How do I find out how much a medication costs?

To know what you will pay for a medication you were prescribed, call your in-network pharmacy directly. They will need your CHPW Member ID number and the prescription from your provider.

If the medication has not been prescribed yet:

Prescription medications have a cost-share based on the tier and your plan.

  1. Know which plan you have, by checking your CHPW Member ID or login to your myCHPW account.
  2. To see the drug type (tier), search our online drug list (formulary) for your plan metal level. In this search tool, you can also see the cost for each tier.
  3. Select the drug and check the tier level. Then scroll down to see what the cost is for that tier under your plan type.
Tip: Double check if the copay or coinsurance is before or after the deductible. If it is labeled “after deductible”, the cost-share amount is what you will pay only after your deductible is met that year.

The formulary is updated throughout the year and may change.

Tip: If a medication you were prescribed shows “PA” next to it in the formulary, you need prior authorization (pre-approval). If you can’t wait, try an Emergency Fill.

Need medication that isn’t listed on our formulary? You or your provider can request a Formulary Exception.

Pre-approval

For certain medications, you will need pre-approval also known as prior authorization before you can fill the prescription.

Most authorizations are good for one year. If a medication you need is not in the formulary, a different type of approval called a formulary exception can be requested.

How do I request Prior Authorization or a Formulary Exception?

You or your provider can send prior authorizations and formulary exceptions through Express Script’s website, by phone, fax, or mail.

Phone: 1-800-753-2851
Fax: 1- 877-328-9660
Mail: Express Scripts
Attn: Benefit Coverage Review Department
PO Box 66587
St Louis, MO 63166-6587

Before requesting a formulary exception or prior authorization, you can also search the Clinical Review Criteria* for Prescription Drugs to confirm what’s needed for approval and check coverage restrictions.

Tip: If your prior authorization request is denied by Express Scripts, you or your provider can request an appeal.

*Not all medications listed in the Clinical Review Criteria will be covered on the formulary. Non-formulary medications are subject to the Medical Necessity for Non-Formulary Medications policy. To verify coverage, review your plan documents and formulary.

Which medications require Prior Authorization?

To check if your medication needs prior authorization or has any coverage restrictions:

  • Ask your provider or pharmacist, or contact us.

Frequently asked questions


What can I do if I need my medication right away, but the pharmacy says it needs approval first?

If you have an urgent medical need and can’t wait for pre-approval or prior authorization, ask your in-network pharmacy for an Emergency Fill. This will allow you to get a one-time fill of your prescription without waiting for prior authorization from your health plan.

The pharmacist will use their best judgment to decide if you have an urgent medical need and if you should get a short supply right away.

CHPW covers Emergency Fills for the drugs on our formulary with the following limitations:

  • Emergency Fills are not available for certain Specialty Drugs: Oncology drugs, hepatitis C, biologics, multiple sclerosis treatments, and enzyme replacements, which do not meet the criteria for “urgent therapeutic need”
  • Not covered at pharmacies that are not in-network, or non-participating.

Only one Emergency Fill, up to a 30-day supply, is covered for a Prescription Drug. If you need another refill of the same medication, you will need to get prior authorization first (or pay full price out of pocket) and follow any other requirements based on your plan.

You will still pay your cost share for the Emergency Fill supply, including applicable deductibles, coinsurance, and copays.

Please refer to your plan’s Schedule of Benefits for details. The cost share is based on the tier, shown in your plan’s drug list (formulary).

My Prior Authorization request was not approved. What now?

Talk to your provider about prescribing you a similar drug that is covered, or about providing us with additional information to show you need it.

You or your provider can also appeal the decision. If you appeal, you are asking us to review our decision to cover the medication again.

How to appeal a coverage decision

You can also get the original prescription filled at your pharmacy, but will be paying the full price if it’s not approved to be covered.

How do I change pharmacies or transfer a prescription?

There’s a few ways to do it:

  • Ask your new pharmacy to contact your old pharmacy to get the prescription transferred. You’ll need your old pharmacy’s contact information, your prescription details, name of the medication, and the dosage.
  • Ask your doctor for a new prescription, and give them your new pharmacy’s name and address. Call your clinic or send a message through your patient portal.

We’re here to help too. We can walk you through the steps, and help you get this done, contact us.
