What to Do When Express Scripts Says Your Medication Needs Prior Authorization

When Express Scripts flags your prescription for prior authorization, it means your medication cannot be dispensed until your provider submits clinical justification. The process is common—and usually solvable—if you act quickly and follow the right steps.

You go to fill your prescription.

Then you see:

“Coverage review required.”

That’s Express Scripts’ way of saying:

👉 Your medication needs prior authorization before insurance will approve it.

This can delay treatment—but it does not mean your medication is denied.

Why Express Scripts requests prior authorization

Express Scripts manages pharmacy benefits for many insurers and employers.

When a medication is flagged, it’s usually because of one of these reasons:

Common medications affected include:

• • testosterone cypionate
  • estradiol patches and gels
  • Ozempic
  • Wegovy
  • Mounjaro
  • Zepbound

Step 1: Find out what’s flagged

Log in to your Express Scripts account and go to:

👉 Prescriptions → Prior Authorizations

You’ll usually see:

• • medication name
  • status of request
  • sometimes the reason coverage review was triggered
  • PA reference number

Write these down before contacting your doctor.

Step 2: Contact your provider immediately

You cannot submit the PA yourself.

Your doctor’s office must send it in.

Give them:

• • medication name + dosage
  • Express Scripts member ID
  • PA reference number
  • phone number listed on your notice

👉 Delays often happen because providers don’t receive complete details early enough.

What your provider usually needs to submit

The required documentation depends on the medication.

For Testosterone Therapy

Most plans require:

• • two early-morning testosterone lab results
  • diagnosis of hypogonadism
  • documented symptoms
  • confirmation of medical evaluation

This testosterone PA checklist guide explains these requirements in more detail.

For Estradiol / HRT

Usually includes:

• • diagnosis documentation
  • symptom severity notes
  • formulary compliance history

For GLP-1 Medications

Most plans require:

• • BMI documentation
  • obesity or diabetes diagnosis
  • previous treatment attempts
  • HbA1c if diabetes applies

If your medication is denied later, this insurance denial guide explains what happens next.

Step 3: Track the status

Once submitted, Express Scripts usually processes:

If there’s no update after 3 business days:

👉 Call member services and confirm:

• • PA was received
  • all documents are complete
  • nothing else is missing

Do not assume “pending” means everything is moving.

Step 4: If your PA is denied

A denial is not final.

You have options.

Option 1: First-level appeal

Your provider can submit:

• • stronger medical necessity letter
  • updated labs
  • added clinical notes

Option 2: Peer-to-peer review

This is often the fastest path.

Your doctor speaks directly with:

👉 Express Scripts reviewing pharmacist or medical director

This is especially effective in borderline cases.

Option 3: External review

If appeals fail:

You may request independent review through your state insurance process.

What you can do while waiting

If your medication is urgent:

Temporary options:

• • pay cash temporarily
  • use manufacturer coupons
  • request bridge supply (7–14 days)
  • ask provider for expedited review

👉 Some medications have strong savings programs while waiting.

Why Express Scripts denials happen so often

Many denials are not true denials.

They happen because:

• • missing documentation
  • incomplete forms
  • incorrect diagnosis codes
  • missing lab data

👉 Most are preventable when submitted correctly the first time.
