# Horizon Patient Services: A Complete Guide to Getting Tepezza at No Cost
Who Qualifies for the Horizon Patient Services?
If you have been prescribed Tepezza (teprotumumab) for Thyroid Eye Disease, you may qualify to receive it at no cost through the Horizon Patient Services patient assistance program. To be eligible, your household income must generally fall at or below $75,300 per year if you live alone. Larger households may qualify at higher income levels. On the insurance side, you must either be uninsured or have commercial (private) insurance that has denied coverage or does not cover Tepezza. Patients with Medicare, Medicaid, or other government-funded insurance are typically not eligible for the free drug program, though other forms of help may be available to you.

About Tepezza (teprotumumab)
Tepezza (teprotumumab) is a prescription biologic medication manufactured by Amgen (formerly Horizon Therapeutics). It belongs to a drug class called insulin-like growth factor-1 receptor (IGF-1R) inhibitors and is FDA-approved specifically for the treatment of Thyroid Eye Disease (TED), a serious condition that affects the muscles and tissues around the eyes. As a biologic infusion therapy, Tepezza requires specialized manufacturing, which makes it one of the more expensive medications available. Without insurance or financial assistance, the cost of a full course of treatment can be substantial, placing it out of reach for many patients. The Horizon Patient Services program exists to help eligible patients access this medication at no cost.

Income Eligibility: Full Breakdown
Horizon Patient Services uses income thresholds based on 500% of the Federal Poverty Level (FPL) for 2025. Your eligibility depends on both your household size and your total annual income. The limits are as follows:
| Household Size | Maximum Annual Income |
|---|---|
| 1 person | $75,300 |
| 2 persons | $102,200 |
| 3 persons | $129,100 |
| 4 persons | $156,000 |
Income is typically verified using your most recent federal tax return, a W-2 form, or three months of recent pay stubs. If your income is above these limits, you may not automatically be disqualified. Many patient assistance programs take medical expenses and financial hardship into account when reviewing applications. It is worth applying even if your income is slightly over the threshold, or speaking with a program representative directly. Household size is also a flexible factor — be sure you are counting all members of your household accurately, as a larger household size raises the qualifying income ceiling.

Step-by-Step: How to Apply
Follow these steps to apply for Tepezza through Horizon Patient Services:
1. Gather your documents. You will need: a completed enrollment form, proof of household income (tax return, W-2, or three months of pay stubs), a physician's prescription for Tepezza, documentation of medical necessity from your doctor, and your signed patient authorization.
2. Download or request the enrollment form. Visit the official support page at https://www.tepezza.com/tepezza-patient-support/ to access the form online. You can also call (833) 483-7399 to request that forms be sent to you or your doctor's office.
3. Have your prescriber complete their section. Your doctor or their office staff will need to fill out the medical necessity portion and provide a valid prescription. Many offices are familiar with this process and can assist.
4. Submit your application. You may apply using multiple methods:
- Online: through the patient support portal at the URL above
- Phone: call (833) 483-7399 for assistance
- Fax: send completed documents to (833) 483-7398
5. Wait for confirmation. After submission, allow 7 to 10 business days for processing. A program representative will contact you or your prescriber with a decision.
6. Follow up if needed. If you have not heard back after 10 business days, call the program directly to check your application status.

What to Expect: Timeline and Delivery
Once your application is approved, processing typically takes 7 to 10 business days. You or your prescriber's office will be notified of the decision. If approved, Tepezza will be shipped directly to your prescriber's office or infusion center, not to your home. This is standard for infusion biologics, which require clinical administration. You do not need to pick up or handle the medication yourself. Your care team will coordinate the infusion appointment. Because this is an annual program, your eligibility will need to be reauthorized once per year. Your prescriber's office or the program will typically prompt you when reauthorization is due, but it is a good idea to track your enrollment date.

Alternatives If You Don't Qualify
If you do not meet the income or insurance requirements for the free drug program, other options may still be available.
1. Biosimilars: There are currently no FDA-approved biosimilar alternatives to Tepezza. This means there is no lower-cost substitution option at this time.
2. Tepezza Savings Card: If you have commercial insurance that covers Tepezza, you may qualify for a co-pay savings card that reduces your out-of-pocket costs. You can learn more and enroll at https://www.tepezza.com/tepezza-patient-support/savings-card.
3. State Pharmaceutical Assistance Programs (SPAPs): Many states offer their own programs to help residents afford prescription medications. Eligibility and benefits vary by state. Contact your state's health department or benefits office to ask what is available in your area.
4. NeedyMeds.org: This free, independent database lists hundreds of patient assistance programs, co-pay cards, and disease-specific funds. Visit www.needymeds.org to search for additional resources by drug name or condition.

Common Questions

You or your prescriber's office will be notified of the decision. Incomplete applications may take longer, so make sure all documents are included when you apply.
No. Because Tepezza is an infusion medication that must be given by a healthcare provider, approved medication is shipped directly to your prescriber's office or infusion center. Your care team will schedule your infusion appointments and handle the medication on your behalf.
It may still be worth applying. Horizon Patient Services, like many patient assistance programs, may consider medical expenses and overall financial hardship when reviewing applications. If you are close to the income limit, contact the program at (833) 483-7399 to discuss your situation before assuming you are ineligible.
Medicare patients are generally not eligible for the manufacturer's free drug program due to federal regulations. However, Horizon Patient Services may be able to refer you to independent charitable foundations that provide financial assistance to Medicare beneficiaries. You can also search for foundation support at NeedyMeds.org or call (833) 483-7399 for guidance.
Yes. The Horizon Patient Services program requires annual reauthorization. You will need to confirm that you still meet the eligibility requirements each year to continue receiving assistance. Your prescriber's office or the program will typically notify you when your reauthorization period approaches, but you should keep track of your enrollment date as well.
