What are medical cost‑sharing programs?

Understanding alternatives to traditional health insurance.

Page last updated on: 5/15/26

Medical cost‑sharing programs – sometimes called health care sharing ministries or cost‑sharing organizations – are an alternative approach some individuals explore instead of traditional health insurance coverage.

While they may sound similar to health insurance, cost‑sharing programs operate differently from Affordable Care Act (ACA) health plans and may involve important tradeoffs.

One well‑known example is Medi‑Share, though there are multiple organizations that offer similar models.

How do medical cost‑sharing programs work?

Members typically contribute a monthly payment – often called a “share” – into a collective pool. These funds may be used to help pay eligible medical expenses submitted by other members.

To participate, individuals usually must meet and maintain specific membership guidelines, which may include lifestyle expectations or behavioral standards set by the organization.

Because these programs rely on voluntary sharing rather than insurance contracts, payment of medical bills is not guaranteed.

Are medical cost‑sharing programs insurance?

No. Medical cost‑sharing organizations are not health insurance plans.

They are typically not regulated in the same way as ACA‑compliant plans, which means they do not provide the same legal protections, consumer safeguards or guarantees of payment.

How do costs compare?

Monthly contributions for cost‑sharing programs may be lower than traditional insurance premiums.

However, these programs generally:

  • Do not include an annual out‑of‑pocket maximum
  • Do not guarantee that large or ongoing medical claims will be shared

This means individuals could be responsible for significant or unlimited costs if expenses are not shared.

Financial assistance and savings

ACA‑compliant health plans may offer financial assistance, like premium tax credits, that can reduce monthly costs and out‑of‑pocket expenses.

Cost‑sharing programs generally do not provide this type of financial help.

What might not be covered?

Coverage varies by organization, but medical cost‑sharing programs may limit or exclude services that are typically covered by traditional insurance, such as:

  • Doctor visits
  • Emergency care
  • Hospitalizations
  • Maternity services
  • Mental health care
  • Prescription medications
  • Preventive services

When might traditional insurance be a better fit?

An ACA health plan may be a more predictable option if you:

  • Need ongoing medical care
  • Want consistent coverage for major health needs
  • Rely on prescription medications
  • Value access to preventive and mental health services
  • Qualify for premium tax credits or other savings

Final thoughts

Medical cost‑sharing organizations, such as Medi‑Share, can appeal to some individuals due to lower monthly contributions and community‑based cost sharing. However, they differ significantly from ACA health plans in terms of regulation, coverage guarantees and financial protection. Carefully evaluating your health care needs, financial situation and risk tolerance can help you determine which option is the best fit.
