TL;DR

• Monthly Cost: Zion starts at $114 for individuals, while CHM starts at $115. Family costs are nearly identical, ranging from $334 to $899 for Zion and $345 to $897 for CHM.
• Initial Unshareable Amount (IUA): CHM offers a much lower IUA ($300, $500, or $1,000) compared to Zion's minimum of $1,250. This means you pay less out-of-pocket for small claims with CHM.
• Coverage Caps: Zion shares unlimited costs per need without add-ons. CHM has a base cap of $125,000 per illness unless you pay for the CHM Plus add-on ($42/unit/month).
• Faith Requirements: Zion has no faith requirement. CHM requires strict Christian adherence, including active church attendance.
• Pre-existing Conditions: Zion covers high blood pressure, cholesterol, and diabetes from month one (if no prior hospitalization). CHM requires 12 months symptom-free for most conditions, and 5 years for cancer.

The Short Version: Stability vs. Flexibility

You are likely here because you want to avoid traditional insurance premiums, but you still need protection against catastrophic medical bills. You have two heavyweights in your sights: Christian Healthcare Ministries (CHM) and Zion HealthShare. Both operate as medical cost-sharing ministries, but they function differently under the hood.

CHM has been around since 1981. It has over 2,000,000 members. It is the veteran in the space. Zion HealthShare is newer, founded in 2019, with over 75,000 members. It markets itself as a modern alternative.

The choice usually comes down to what you value more: lower upfront costs with stricter rules (CHM), or broader coverage with more flexibility (Zion).

If you need to see a mental health specialist or want HSA compatibility, Zion is your only option between the two. If you are healthy, attend church regularly, and want the lowest possible IUA, CHM might be the better financial fit.

This comparison isn't about which plan is "better." It is about which plan protects your specific situation without breaking the bank.

Monthly Contributions and IUA Structures

Let’s look at the numbers. When you sign up, you are committing to a monthly contribution. For the individual, Zion HealthShare contributions start at $114 and go up to $320 depending on your age band. For a family, the range is $334 to $899.

CHM individual contributions run from $115 to $299. Family contributions sit between $345 and $897.

On the surface, the monthly costs are virtually the same. You will not save hundreds of dollars a year by choosing one over the other based on the monthly bill alone. The real difference appears when you make a claim.

Both plans use an Initial Unshareable Amount (IUA). This is the amount you must pay before the ministry shares the rest of the bill.

• CHM Options: $300, $500, or $1,000.
• Zion Options: $1,250, $2,500, or $5,000.

CHM allows you to choose an IUA as low as $300. Zion's lowest tier starts at $1,250.

Imagine you break your arm and the bill is $4,000.

• With CHM (at the $300 IUA), you pay $300, and the ministry shares the remaining $3,700 (subject to co-share).
• With Zion (at the $1,250 IUA), you pay $1,250, and the ministry shares the remaining $2,750.

CHM wins here on small-to-medium claims. However, Zion includes a co-share percentage between 10-20% on top of the IUA. CHM has a flat 20% co-share on top of the IUA.

If you have a massive bill, say a $150,000 surgery, the IUA matters less than the coverage cap. This is where Zion pulls ahead for those with chronic issues.

Coverage Details: The "Hidden" Exclusions

Coverage lists often look identical on paper. "Surgery," "Emergency," "Preventive." But the devil is in the details.

Prescriptions and Mental Health

Zion HealthShare explicitly covers prescriptions, mental health care, and telehealth. You can submit pharmacy bills for sharing, and you can see therapists through the network.

CHM does not list prescriptions or mental health in its standard coverage summary. It covers maternity, preventive care, emergency services, and surgery. If you require ongoing psychiatric medication or therapy, CHM will not share those costs. You must pay them out of pocket entirely.

Zion also supports HSA-compatible accounts. This means you can use pre-tax dollars from an HSA to pay your monthly contribution or IUA. CHM is not HSA-compatible. If you have an HSA, Zion integrates with it; CHM does not.

Maternity

Both plans cover maternity, but the structures differ. Zion includes it in the standard share. CHM covers it, but you must check the specific guidelines for pregnancy timing and requirements. For those planning a family, verify the current guidelines before conceiving.

The Cap Issue

This is the most critical differentiator.

Zion shares unlimited per need. There is no annual or lifetime cap. If you get sick for a year and the bill is $500,000, Zion shares it (after the IUA and co-share).

CHM has a base sharing cap of $125,000 per illness.

• If your illness costs $100,000, CHM shares it.
• If your illness costs $200,000, CHM shares $125,000. You are responsible for the remaining $75,000.

To fix this, CHM offers the CHM Plus add-on. It costs $42 per unit per month.

• Silver/Bronze Plus extends the cap to $1,000,000 per illness.
• Gold Plus extends the cap to unlimited.

To match Zion's standard coverage, you must pay an extra $42/month for CHM Gold. For a family of four, that is an extra $168/month ($42 x 4 units) just to get unlimited coverage.

Faith Requirements and Lifestyle

You cannot ignore the lifestyle requirements. Health sharing is not just financial; it is often a spiritual commitment.

Zion HealthShare

• Faith Requirement: Any-faith.
• Church Attendance: False.
• Summary: You do not need to be Christian to join. You do not need to attend church.

CHM

• Faith Requirement: Christian-strict.
• Church Attendance: True.
• Summary: You must adhere to a strict Christian faith. You must provide proof of active church attendance.

For secular families or those of other faiths, CHM is not an option. For traditional Christian families who want accountability, CHM's requirements might feel like a feature rather than a bug.

However, be honest with yourself about the church attendance requirement. If you miss services frequently, or if you travel for work constantly, this can become a compliance issue. CHM takes this seriously. Zion does not track your spiritual life.

Pre-existing Conditions: The Waiting Game

If you have a chronic condition, this section decides your choice.

Zion HealthShare Pre-existing Rules

• Lookback: 24 months.
• Phase-in: Any condition diagnosed or treated in the last 24 months is subject to a phase-in period before becoming eligible.
• The Exception: High blood pressure, high cholesterol, and diabetes are covered from month one.
• Condition for Exception: None of these exceptions can have resulted in hospitalization in the prior 12 months.
• Other Conditions: Face a phase-in period. You must check the Member Guidelines PDF for the exact schedule.

CHM Pre-existing Rules

• Standard Rule: A condition is no longer pre-existing after 12 months symptom-free and treatment-free.
• Cancer: Requires 5 years cancer-free.
• Heart/Hereditary: Require 5 years symptom-free (based on general industry standards for similar strict ministries, though CHM specifically notes cancer and diabetes rules). Note: Check the specific member guidelines for the full list of chronic exclusions.

Scenario A: High Blood Pressure

• Zion: Covered immediately (if no hospitalization last 12 months).
• CHM: You must go 12 months without symptoms or treatment. If you take medication, you are treated. If you take medication, the condition is not shared.

Scenario B: Cancer Survivor

• Zion: Subject to the 24-month lookback phase-in.
• CHM: You must be cancer-free for 5 years.

Scenario C: New Diagnosis

• If you join today and are diagnosed tomorrow, Zion phases it in over time. CHM waits 12 months for that new diagnosis to become shareable.

Zion is generally more flexible for common chronic issues like diabetes and hypertension, provided you haven't been hospitalized recently. CHM is stricter on the definition of "pre-existing." If you are healthy and stay that way, CHM is fine. If you manage a chronic condition, Zion's exceptions are valuable.

Network vs. Freedom

Neither plan forces you into a PPO network for basic care.

Zion HealthShare: No provider network. You can see any doctor. CHM: No provider network. You can see any doctor.

This is a massive advantage over traditional insurance. You do not need to worry about "in-network" status. However, you must still submit claims.

Zion uses the PHCS network for discounts sometimes, but they market the freedom to choose any doctor. CHM has the same freedom. The difference is in the administrative side. Zion is newer and has a rating of 4.8/5. CHM is older with a 4.4/5 rating.

Zion has 75,000+ members. CHM has 2,000,000+ members.

More members can mean faster processing times because of economies of scale. However, larger ministries also face higher scrutiny from state regulators. CHM has been around since 1993 (Medi-Share is 1993, CHM is 1981). Zion founded in 2019.

If you value a 40-year track record, CHM wins. If you value a modern interface and newer technology stack, Zion might appeal more.

The CHM Plus Add-On Value Proposition

We touched on this earlier, but it deserves its own section because it changes the math.

Zion costs $114-$320/month. That gets you unlimited sharing. CHM costs $115-$299/month. That gets you $125,000 sharing.

To get unlimited sharing on CHM, you add Gold Plus. That is $42/unit/month. If you are a family of four, that is $168/month extra. Total Family Cost for CHM Gold: $345 + $168 = $513 (minimum). Total Family Cost for Zion: $334 (minimum).

In this specific case, Zion is actually cheaper for a family of four if you need unlimited coverage. You do not pay the $42/unit surcharge.

However, if you are an individual:

• Zion Individual: $114.
• CHM Individual: $115 + $42 = $157.

CHM is more expensive for individuals who need unlimited coverage. CHM is only cheaper if you accept the $125,000 cap on your medical bills. For most healthy people, $125,000 is enough. For people with complex health needs, it is not.

This makes Zion the superior choice for high-risk households unless the CHM monthly rate drops significantly for your age band.

Which Wins in 2026?

There is no single winner. There is only the right fit for your risk profile.

Choose Zion HealthShare if:

1. You need coverage for prescriptions or mental health.
2. You have pre-existing conditions like high blood pressure or diabetes that require medication.
3. You want unlimited coverage without paying an extra add-on fee.
4. You are not Christian or do not want to prove church attendance.
5. You want to use an HSA.

Choose CHM if:

1. You are healthy and have no pre-existing conditions.
2. You want the lowest possible IUA ($300 vs $1,250).
3. You want the longest track record (founded 1981).
4. You are a strict Christian who attends church regularly.
5. You can accept a $125,000 cap per illness (or are willing to pay $42/unit for Plus).

Final Thoughts

Health sharing requires you to be your own advocate. You must understand your IUA, your co-share, and your limits.

If you choose CHM, do not ignore the $125,000 cap. Ask yourself: "If I spend $200,000 on a treatment in a single year, can I afford the $75,000 difference?" If the answer is no, you need the CHM Plus add-on, and Zion becomes a cheaper option.

If you choose Zion, do not ignore the higher IUA. If you visit the ER frequently for minor issues, the $1,250 minimum could add up in out-of-pocket costs before sharing begins.

Visit our advisor page to run a personalized quote for both plans. The numbers change based on your exact age and zip code.

Use the data above to filter out the plans that do not meet your baseline requirements (faith, pre-existing, prescription). Once you narrow it down to two, the choice is purely financial.

Ultimately, Zion offers a modern, flexible safety net with higher deductibles. CHM offers a traditional, lower-deductible safety net with stricter rules and lower base caps. Pick the one that matches your health reality and your budget.
