💡 Key insight most patients don't know
For common generics — metformin, lisinopril, atorvastatin, sertraline, omeprazole — the cash price via pharmacy bidding is often lower than your insurance copay would have been. If your prior auth was denied for one of these drugs, the denial may have actually saved you money. Upload your Rx to Script Unlock and see what pharmacies offer.
What is prior authorization?
Prior authorization (also called prior approval or pre-auth) is a requirement where your insurance company must approve a medication before they'll cover it. Your doctor submits clinical information to justify the prescription is medically necessary. Insurers then approve, deny, or request more information — a process that can take days or weeks.
Why prior auth gets denied (4 common reasons)
Not on formulary
Your plan doesn't cover that specific drug. Fix: ask for a formulary exception or therapeutic alternative.
Step therapy required
Your insurer wants you to try a cheaper drug first. Fix: document that step drugs failed or are contraindicated.
Quantity limit exceeded
You're requesting more doses than your plan allows. Fix: submit clinical documentation of medical necessity for higher quantity.
Missing clinical documentation
The PA request lacked required clinical information. Fix: your doctor resubmits with diagnosis codes, lab results, and treatment history.
5 options when prior auth is denied — ranked by speed
Start with option 1 while you pursue options 2-4 in parallel.
Cash pay via pharmacy bidding
Same dayUpload your prescription to Script Unlock. Verified pharmacies bid against each other for the lowest cash price. First bids typically arrive within 1–4 hours. No insurance needed — and for many common generics, the cash price is lower than your copay would have been.
Best for: generic drugs, urgent need, when cash price < copay
Ask prescriber to resubmit PA with clinical notes
3–14 daysYour doctor can resubmit the prior authorization request with detailed clinical documentation: why this specific medication is medically necessary, what alternatives you've tried and failed, and any relevant lab results. Success rate: 40–60% on resubmission.
Best for: specialty drugs, brand-name medications, high-cost biologics
File an internal appeal
30 daysSubmit a formal written appeal to your insurance company. Include your doctor's letter explaining medical necessity, supporting clinical evidence, and the exact denial reason. By law, insurers must respond within 30 days (72 hours for urgent requests).
Best for: when initial PA resubmission fails, documented medical necessity
Request an external independent review
45–60 daysIf internal appeal fails, request an external review by an independent organization. Insurers must accept the decision. This is your legal right under ACA. For urgent/life-threatening situations, request expedited external review (72-hour turnaround).
Best for: urgent/life-threatening conditions, after internal appeal fails
Manufacturer patient assistance programs
Weeks to monthsMost major drug manufacturers offer free or discounted medication to patients who can't afford their drugs. Income-based. Application process takes several weeks. Best for expensive brand-name drugs where cash price is also unaffordable.
Best for: high-cost brand drugs, income-qualifying patients
Step therapy: "try this cheaper drug first"
Step therapy (fail-first) requires you to try a cheaper medication before your insurer covers the prescribed drug. To get an exception, your doctor must document:
- You tried the required step drugs and they failed (adverse effects, no efficacy)
- The required step drugs are medically contraindicated for you
- You are stable on the current drug and changing would cause harm
- The prescribed drug is clinically superior for your specific condition
Most states have step therapy exception laws. Ask your doctor to explicitly request a step therapy exception by name.
Frequently asked questions
What is prior authorization?
Prior authorization (PA) is a requirement from your insurance company that your doctor must get approval before they will cover a specific medication, procedure, or service. Your insurer reviews medical records and clinical justification before deciding whether to approve the coverage.
How do I appeal a denied prior authorization?
First, request the denial reason in writing. Then ask your prescriber to submit a PA with detailed clinical notes explaining medical necessity. If that fails, file an internal appeal with your insurer (30-day window). For urgent needs, request an expedited review. If still denied, you have the right to an independent external review.
How long does prior authorization take?
Standard prior authorizations take 3-14 business days. Expedited/urgent requests must be processed within 72 hours (3 business days) by law. Appeals take 30 days for standard and 72 hours for expedited. External appeals take up to 45 days.
Can I pay cash instead of waiting for prior auth?
Yes — and for many common generic drugs, the cash price via pharmacy bidding is actually LOWER than your copay, making prior auth irrelevant. Upload your prescription to Script Unlock and verified pharmacies will bid on it within hours. No insurance needed.
What is step therapy and how do I get an exception?
Step therapy (also called fail-first) requires you to try cheaper medications before your insurer covers the preferred drug. To request an exception, your doctor must document that: (1) you tried and failed the required step drugs, (2) the required drug would be harmful to you, or (3) the prescribed drug is needed for a specific medical condition. Most states have step therapy exception laws.
