Introduction

Keytruda (pembrolizumab) is one of the most widely used immunotherapy drugs for cancer treatment in the U.S. But one question haunts many patients: how much will I really pay if I have insurance? The short answer is: it depends — on your insurance plan, dosage schedule, and assistance programs. In this article, we'll break down the latest list prices, average out-of-pocket costs, compare what uninsured patients pay, and provide strategies to reduce your expenses. We’ll also include tables, comparisons, FAQs, and references to trusted sources to make this article compete for top ranking in Google.

Latest List Prices & Dosing (2025 Data)

Keytruda’s manufacturer provides “list prices” (also called wholesale acquisition cost, WAC) that are often far higher than what insured patients actually pay. Keytruda+1

Below is a summary of the list prices for standard dosing regimens as of 2025:

Dosing regimen	List price per infusion / dose	Notes
200 mg every 3 weeks	≈ $12,031.36	This is a manufacturer-listed price. Keytruda
400 mg every 6 weeks	≈ $24,062.72	Equivalent to two doses every 3 weeks. Keytruda
Alternative list (GoodRx)	200 mg dose ~ $11,337.36	Reflects published list pricing on GoodRx site. GoodRx

Important caveats:

These are list prices before insurance discounts, rebates, or negotiated rates.

They typically exclude infusion center fees, administration costs, facility fees, lab tests, etc.

Many patients will never pay these full amounts.

Estimated Cycle / Monthly Cost (with & without Insurance)

To give context, researchers often model Keytruda cost per “cycle” or per “28-day period.” One source estimates:

$11,733 per 28-day cycle (for monotherapy) NCBI
In combination therapies, cost per 28-day cycle may rise to $14,107–$17,133 depending on adjunctive chemotherapy. NCBI

If a patient receives infusions every 3 weeks, the cost accumulates over time significantly.

With insurance, a substantial proportion of patients may pay nothing or small copays (after deductibles are met). According to Keytruda’s own published data:

59% of commercially insured patients paid $0 out-of-pocket for a 200 mg dose. Keytruda
For those paying something, ~80% paid between $0.01 and $375 per infusion (after deductible). Keytruda
In Medicare populations: 39% of Medicare Advantage patients paid $0; for those paying, costs ranged up to ~$1,325 per infusion. Keytruda+1

Table: What Insured Patients Actually Pay (Estimated)

Patient type / insurance	% who pay $0	Typical paid range per infusion	Notes
Commercial / private insurance	~59%	$0 to $375	After deductible, before copay assistance Keytruda
Medicare Advantage	~39%	$0 to ~$925	After deductible, coinsurance Healthline
Traditional Medicare (Part B)	—	~20% of Medicare-approved amount + deductible	Also pay Part B deductible, coinsurance Healthline
Medicaid	—	$4–$8 per infusion	In many states, patients with Medicaid pay a nominal amount. Drugs.com

Comparison: Insurance vs No Insurance

Scenario	What you might pay	Explanation
Uninsured / cash pay	~$11,300+ per 200 mg infusion	Based on list pricing for 200 mg (e.g. $11,337.36) Healthline
With insurance (commercial)	Often $0, or up to a few hundred dollars	Copays or coinsurances apply; many pay nothing due to assistance Keytruda
With Medicare	Deductible + 20% coinsurance	Medicare Part B covers many infusions, but you still pay out-of-pocket. Healthline+1
With Medicaid	Typically $4–$8	State programs often subsidize or cover nearly all costs for low-income patients. Drugs.com

How Insurance Plans Affect Your Cost

Your actual out-of-pocket cost depends on many variables:

Deductible — Until you hit your deductible, you may pay more.
Coinsurance / copay — After deductible, you pay your plan’s share.
Prior authorization — Many plans require approval before covering Keytruda.
In-network vs out-of-network — Facility or hospital network matters.
Additional coverage / supplemental insurance — e.g. Medigap for Medicare, secondary insurers.
Drug assistance / copay assistance programs — see next section.

Financial Assistance & Copay Support

To reduce patient burden:

Merck Co-pay Assistance Program: Eligible privately insured patients may pay as little as $25 per infusion (with caps). Merck Access Program
This program does not apply to patients on government insurance (Medicare or Medicaid). Merck Access Program
Merck Patient Assistance Program: Provides Keytruda free (or at reduced cost) to eligible uninsured or underinsured patients. Merck Access Program
Nonprofits and independent copay foundations may also help. Healthline+1

Emerging Developments & Price Pressures
