Do most health insurance plans include BIMZELX in their formulary, and what are the typical requirements?

Summary: Navigating BIMZELX Insurance Coverage—What Actually Works and What Trips You Up Ever tried to get a new prescription covered—especially one like BIMZELX, a biologic for plaque psoriasis—and felt like you entered a labyrinth? I’ve been through that maze, and, frankly, the process is less about “is it covered?” and more about figuring out how it gets covered, what hoops you jump through, and what’s hiding in the fine print. In this guide, I’ll break down what I learned (with some detours), show exactly what steps I took (screenshots included), and flag those weird insurance requirements that aren’t always obvious at first glance. Plus, I’ll bring in some real-world data, expert commentary, and regulatory tidbits that actually matter for your wallet. If you want to skip the “should I bother?” phase and move straight to action, you’re in the right place. How BIMZELX Shows Up on Insurance Formularies: The Reality First, let’s set expectations. BIMZELX (bimekizumab) is one of the newer biologics approved for moderate-to-severe plaque psoriasis (FDA approval: October 2023). Its clinical effectiveness has made it a candidate for inclusion on many insurance formularies, but being “on the list” doesn’t guarantee hassle-free access. I checked three major PBMs (pharmacy benefit managers) via their public formulary lookup tools: CVS Caremark, Express Scripts, and OptumRx. Here’s what I found: CVS Caremark: BIMZELX is listed as a specialty-tier drug, prior authorization required. Express Scripts: Covered, but with step therapy (prove you tried and failed other treatments first). OptumRx: Also covered, but again, requires prior authorization and, in some plans, a copay assistance program is suggested. So, most commercial plans do cover BIMZELX, but you’ll almost always face hurdles like prior authorization or mandatory step therapy. Medicare coverage is spottier—Medicare Part D plans can include it, but not universally. Medicaid coverage varies by state (see Medicaid Drug Utilization Data). The Actual Steps: How I (Eventually) Got BIMZELX Approved Here’s my real-world process—messy, with a few wrong turns. I’ll drop screenshots and redacted docs where allowed. (If you want to see a sample prior authorization form, check this CVS PA Criteria PDF.) Step 1: Confirm Formulary Inclusion Before bugging your doctor, check your plan’s online formulary. I went to my insurer’s portal, searched “Bimzelx,” and—yes—found it listed, but with a big red “PA” (prior authorization). Screenshot below: Sample formulary lookup: BIMZELX listed, prior authorization required Step 2: Doctor’s Office—The Real Gatekeeper This is where I hit my first snag. My dermatologist’s nurse said, “Most plans need proof you’ve tried at least two other systemic treatments first.” She pulled up a form (looked just like the CVS PA Criteria linked above) and started filling out dates and doses of my previous meds. She also had to attach my recent lab work showing my diagnosis. Step 3: Prior Authorization Submission (And Rejection… Then Approval) First try? Rejected. Turns out, my previous biologic trial was less than three months—insurance wanted “adequate duration.” Had to wait, get another month in, then resubmit. Second time, it was approved—but only after my doctor included a “Letter of Medical Necessity” explaining why BIMZELX was the preferred option for my stubborn case.

My plan required using a specialty pharmacy (home delivery). The copay? Initially $1,200/month. Luckily, BIMZELX offers a copay card (details here), which brought my out-of-pocket down to $0. I had to enroll online and upload proof of insurance. Common Insurance Requirements for BIMZELX Insurers have some patterns when it comes to biologics like BIMZELX. Here's what I gathered from payer policy summaries (Aetna clinical policy, for example): Diagnosis confirmation: Chart notes, lab results, and sometimes photographs. Step therapy: Must have tried at least two other approved treatments (often methotrexate or another biologic). Prior authorization: This is almost universal for BIMZELX, as with most high-cost specialty drugs. Specialty pharmacy requirement: Drug shipped from a designated pharmacy, not your local store. Periodic reauthorization: Every 6-12 months, you’ll need to show continued medical necessity. Official Guidance and Regulatory Framework Under the Centers for Medicare & Medicaid Services (CMS) regulations, Medicare plans can include (but are not required to include) new specialty drugs like BIMZELX. Each state Medicaid program decides coverage under its own Preferred Drug List (see official data). Commercial insurers, meanwhile, follow their own Pharmacy & Therapeutics (P&T) committee decisions, often referencing national guidelines from organizations like the National Comprehensive Cancer Network (NCCN).

She navigates prior authorization, copay cards, and specialty pharmacy coordination. Time from prescription to first dose: 6 weeks. Ben (UK): NHS England follows NICE guidance. BIMZELX is covered only if specific clinical criteria are met (see NICE TA723). Ben’s dermatologist files an application; approval is straightforward if criteria are met, but access is restricted to specialized NHS centers. Time from prescription to first dose: 4 weeks. Difference? The US system is more fragmented, with more paperwork and variability between insurers. The UK is stricter about indications, but less variable once you meet the guidelines. Expert Insights: “The Real Challenge Is Navigating the Payer’s Maze” I had a chance to talk to Dr. Rachel F., a pharmacy benefit consultant, who put it bluntly: “The real challenge for patients isn’t whether BIMZELX is technically covered—it’s whether they can clear all the administrative hurdles. Prior auths, step edits, documentation, and appeals are the real gatekeepers.” She recommends always asking your provider’s office for a copy of the authorization submission and following up every few days.

Even if BIMZELX is on your plan’s formulary, expect paperwork, delays, and sometimes denials before approval.

If you’re just starting the process, here’s what I’d do differently: Check your own plan’s formulary (not just a general one) before seeing your doctor.

Sign up for copay assistance as soon as you get the prescription.

Common Insurance Requirements for BIMZELX

Insurers have some patterns when it comes to biologics like BIMZELX. Here's what I gathered from payer policy summaries (Aetna clinical policy, for example):

Diagnosis confirmation: Chart notes, lab results, and sometimes photographs.
Step therapy: Must have tried at least two other approved treatments (often methotrexate or another biologic).
Prior authorization: This is almost universal for BIMZELX, as with most high-cost specialty drugs.
Specialty pharmacy requirement: Drug shipped from a designated pharmacy, not your local store.
Periodic reauthorization: Every 6-12 months, you’ll need to show continued medical necessity.

Official Guidance and Regulatory Framework

Under the Centers for Medicare & Medicaid Services (CMS) regulations, Medicare plans can include (but are not required to include) new specialty drugs like BIMZELX. Each state Medicaid program decides coverage under its own Preferred Drug List (see official data). Commercial insurers, meanwhile, follow their own Pharmacy & Therapeutics (P&T) committee decisions, often referencing national guidelines from organizations like the National Comprehensive Cancer Network (NCCN).

Here’s a comparison table for “verified trade” standards for specialty drug coverage across several countries, just to highlight the differences:

Country	Program Name	Legal Basis	Enforcement Agency	Specialty Drug Standard
USA	Medicare, Medicaid, Commercial Insurance	Affordable Care Act, CMS Regulations	CMS, State Medicaid Agencies, PBMs	Step therapy, PA, formulary status
Canada	CADTH, Provincial Plans	Canada Health Act	Health Canada, Provincial Authorities	Health technology assessment, prior approval
UK	NHS England	National Health Service Act	NHS England, NICE	NICE guidelines, restricted access
Australia	PBS (Pharmaceutical Benefits Scheme)	National Health Act	Department of Health	PBS listing, specialist approval

Case Study: A Tale of Two Countries

Let’s play out a scenario: Anna in the US and Ben in the UK both need BIMZELX for severe psoriasis.

Anna (US): Her commercial insurance lists BIMZELX, but she must prove she failed Humira and Stelara, with months of documentation. She navigates prior authorization, copay cards, and specialty pharmacy coordination. Time from prescription to first dose: 6 weeks.
Ben (UK): NHS England follows NICE guidance. BIMZELX is covered only if specific clinical criteria are met (see NICE TA723).
