How much does a medical bill advocacy benefit cost?

It depends on the pricing model. The common ones are a flat per employee per month fee, a fee per case, a percentage of the savings paid by the employee, and models that are free to the employer because the employee pays a fee. Ask each vendor what the person pays, what the organization pays, and what counts as a saving.

Is medical bill advocacy the same as health navigation?

No, though they overlap. Navigation mostly helps people get care and understand coverage. Medical bill advocacy starts from a bill the person already has and works it until it is resolved. Many navigation vendors take billing questions, so check how far yours goes before adding a bill advocacy benefit.

Does a medical bill advocacy benefit lower health plan costs?

Not directly, and be wary of a vendor that says it does without a defined measurement. Bill advocacy works the bill the employee is left holding, after the plan has paid its share. The benefit is financial relief for the employee and less bill casework reaching HR.

What Is a Medical Bill Advocacy Benefit? How It Works and What It Costs

Q: What is a medical bill advocacy benefit?

A medical bill advocacy benefit is a service an employer or other organization offers so its employees or members have someone to work a medical bill for them. The service checks the bill for errors, applies for hospital financial assistance, helps with insurance appeals and talks to the provider. The person works with the service directly and the organization gets aggregate reporting.

Most benefits help before or during care: the plan pays the claim, the navigator finds the doctor. A medical bill advocacy benefit is for afterwards, when the bill arrives and the employee is on their own with it.

Quick answer

A medical bill advocacy benefit is a service an organization offers so its employees or members have someone to work a medical bill for them. It checks the bill for errors, applies for hospital financial assistance, helps with insurance appeals and talks to the provider. The person works with the service directly, and the organization gets aggregate reporting, never the bills themselves.

The short definition

A medical bill advocacy benefit is an employee or member benefit that resolves medical bills after care. It sits after the claim: the plan has paid what it is going to pay, and what is left is a bill with the person's name on it.

That layer has grown. In KFF's 2025 employer survey, 53% of covered workers at firms with 10 to 199 workers had a general single deductible of $2,000 or more. In KFF's health care debt survey, 41% of US adults said they were carrying medical or dental debt.

What it covers

A good service works whichever route fits the bill, not just one:

Billing errors: checking the bill against the EOB and the itemized charges and getting wrong charges corrected. See billing error review.
Hospital financial assistance: every nonprofit hospital has to have a financial assistance policy, and most people never apply. See financial assistance support.
Surprise and balance bills: using No Surprises Act protections and good faith estimate disputes. See surprise bill support.
Insurance denials: helping the person appeal inside the plan's deadlines. See denial appeals.
Discounts and payment plans: self-pay and prompt-pay discounts, and interest-free terms on what is left.

How it works

The organization launches access. Usually a pilot with an agreed population, scope and reporting, and launch materials for employees.
The person sends their bill. Directly to the service, with their own authorization. HR doesn't collect or forward anything.
The service investigates and acts. At mediloop, AI-powered investigation reads the bill and checks every charge, then a human advocate, who is on every case, contacts the provider or insurer.
The organization gets totals. Use, cases worked and outcomes, in aggregate. Under HIPAA, a group health plan can give the employer summary health information, and the service doesn't need to show HR anything more.

How it is priced

There are four common models. None is right in every case, but each one rewards something different, so it is worth knowing which you are buying:

Per employee per month (PEPM): the organization pays a fixed fee for everyone eligible. Easy to budget, and employees pay nothing.
Per case: the organization pays for each case worked, often with an agreed allowance. Cost follows use.
Percentage of savings: the employee pays a share of what is saved. Free to the organization, but it matters a lot how a saving is counted, and small bills may not be worth the vendor's time.
Free to the employer, employee pays a fee: the organization offers access and the employee pays per bill. Ask whether the fee is flat or a percentage, and whether there is a guarantee.

mediloop prices partnerships per organization, based on the eligible population, scope and case allowance, and agrees it before launch. Individuals can also use mediloop directly for a flat $129 per bill, refunded if the bill isn't lowered by at least that much.

Who offers it

Employers are the obvious buyer, but the same benefit reaches people through benefits brokers, TPAs and health plans, health shares, unions and benefit funds, benefits and ICHRA platforms, financial wellbeing apps and PEOs.

Is it worth adding?

Start with what you already have. An EAP usually won't work a bill, because to stay an excepted benefit it can't provide significant medical care or be coordinated with the health plan. A navigation vendor might, so ask how far it goes. Our comparison of advocacy, navigation and EAPs has the four questions to ask.

If there is a gap, the case for adding one is simple: asking works more often than people expect. In a 2023 national survey in JAMA Health Forum, about a quarter of people who contacted the billing office about a bill had it corrected. Most people never ask. Before you pick a vendor, run them through our 12 question checklist.

A group health plan may give the plan sponsor summary health information (for premium bids or amending the plan) and enrollment information. Disclosing other protected health information requires plan documents that restrict the sponsor's use and a certification from the sponsor.
eCFR, 29 CFR 2590.732(c)(3)(vi), employee assistance programs as excepted benefits
An EAP is an excepted benefit only if it does not provide significant benefits in the nature of medical care, is not coordinated with another group health plan (no requirement to use the EAP first, no eligibility tied to the plan), and requires no employee premiums, contributions or cost sharing.
IRS, Financial assistance policy, section 501(r)(4)
Charitable hospitals must have a written financial assistance policy and an emergency medical care policy, and must publicise them widely.
