How to Help Your Patients Save Money on Thyrogen Kit: A Provider's Guide to Savings Programs

For endocrinologists, nuclear medicine physicians, and oncologists who prescribe Thyrogen Kit (thyrotropin alfa), cost-related barriers are a real clinical obstacle. The retail cash price of a complete two-injection Thyrogen treatment exceeds $4,000, and even insured patients can face significant out-of-pocket exposure. Understanding the financial support landscape — and proactively connecting your patients with the right programs — is as much a part of Thyrogen care as the clinical protocol itself. This guide covers every major savings mechanism available to your patients in 2026.

Understanding the Thyrogen Billing Landscape

Before reviewing patient assistance programs, it is important to understand how Thyrogen Kit is billed — because the billing pathway affects which savings programs apply.

Thyrogen Kit is typically billed as a medical benefit (not a pharmacy benefit) because it is administered in a clinical setting by a healthcare provider. This means:

Medicare: Billed under Medicare Part B (outpatient medical), not Part D (pharmacy). Part B pays 80% of the Medicare-approved amount after the annual deductible. Supplement (Medigap) plans may cover the remaining 20%.

Commercial insurance: Coverage varies by plan. Some plans cover Thyrogen under the medical benefit; others require it to be billed through the specialty pharmacy benefit. Prior authorization is almost universally required.

Medicaid: Coverage varies by state. Medical necessity documentation and prior authorization are typically required.

Understanding which benefit category Thyrogen falls under for each patient is the first step in helping them access the right financial assistance programs.

Program 1: Thyrogen Co-Pay Assistance Program

The Thyrogen Co-Pay Assistance Program is the primary financial support mechanism for commercially insured patients. Your practice can help eligible patients enroll through ThyrogenONE.

Key Details for Providers

Benefit: Covers up to $1,000 of the patient's out-of-pocket drug costs per calendar year

Eligibility: Must have commercial (private) insurance; must have out-of-pocket costs exceeding $100; NOT available to patients with Medicare, Medicaid, TRICARE, or other government insurance

Exclusions: Does not cover injection or administration charges. Patients in MA, MI, or RI have limitations per state law.

Program period: January 1–December 31 annually; re-enrollment may be needed each year

How to enroll: Call ThyrogenONE at 1-888-497-6436 or download the Co-Pay Self Application Form from thyrogen.com. Enrollment can also happen retroactively if the patient has already been billed.

Best practice: Initiate Co-Pay Program enrollment at the same time you initiate prior authorization. This minimizes the time between insurance approval and patient out-of-pocket resolution, preventing "sticker shock" at billing.

Program 2: Sanofi Patient Connection Patient Assistance Program

For patients who are uninsured, underinsured, or whose insurance does not cover Thyrogen, the Sanofi Patient Connection program can provide Thyrogen at no cost or at a substantially reduced cost based on income eligibility.

Key Details for Providers

Benefit: Thyrogen provided at no cost or subsidized cost for eligible patients

Eligibility: Income-based; evaluated case by case. Patients must be uninsured, underinsured, or have insurance that does not cover Thyrogen.

Application: Download from thyrogen.com or via ThyrogenONE. Requires prescriber signature. Both patient and physician complete the form.

Timeline: Allow adequate lead time — application processing may take 2 or more weeks. Factor this into your procedure scheduling.

Program 3: Medicare Part B — What Providers Need to Know

For your Medicare patients, Thyrogen Kit is covered under Part B when administered in a physician office or outpatient hospital setting. Medicare pays 80% of the approved amount after the annual Part B deductible. Key points for billing:

Submit the claim under the appropriate J-code (thyrotropin alfa) for Medicare Part B reimbursement

Ensure the setting of service is correctly documented as physician office or hospital outpatient for Part B eligibility

Patients with Medicare Advantage plans: confirm the plan's specific Thyrogen coverage terms with the plan before scheduling

For Medicare patients facing cost-sharing burden: ThyrogenONE can help connect them with independent charitable foundations (the manufacturer's own Co-Pay Program does not apply to Medicare patients)

Program 4: ThyrogenONE — Your Central Resource

ThyrogenONE (1-888-497-6436) is Sanofi Genzyme's dedicated hub for Thyrogen support. For providers, it functions as a one-stop resource for:

Patient eligibility verification for Co-Pay and Patient Assistance programs

Prior authorization support and appeal navigation

Specialty pharmacy identification and supply navigation

Connecting patients with independent co-pay assistance foundations when manufacturer programs don't apply (e.g., Medicare patients)

Recommendation: Provide the ThyrogenONE number (1-888-497-6436) to every patient being scheduled for Thyrogen. Include it in your patient education materials, appointment reminder letters, and discharge summaries after the procedure.

Helping Patients Who Fall Through the Cracks

Some patients will not qualify for any of the above programs — for example, Medicare patients with high cost-sharing and no supplement plan, or patients who exceed income limits for PAP. For these patients, ThyrogenONE case managers will work to identify independent non-profit co-pay assistance foundations that may be able to help regardless of insurance type. Document in the chart that financial assistance navigation was attempted, with the outcome.

Using medfinder to Support Your Patients

Once financial barriers are addressed, access barriers remain. For patients who have coverage but struggle to locate a facility or specialty pharmacy with Thyrogen in stock, direct them to medfinder for providers. medfinder contacts specialty pharmacies and facilities on the patient's behalf to locate available Thyrogen Kit, reducing administrative burden on your team and getting patients to their procedures faster.
