Health Shares and Pre-Existing Conditions: How the Rules Usually Work
How health sharing ministries treat pre-existing conditions: look-back periods, phase-in limits and a real example from published sharing guidelines.
If you have a health condition, the pre-existing condition section of a health share's guidelines is the most important part to read. Unlike ACA-compliant insurance, health care sharing ministries don't have to share costs for conditions you had before joining (NAIC (opens in new tab)). Nebraska's regulator also warns that pre-existing condition restrictions may disqualify you from having a bill shared (Nebraska DOI (opens in new tab)).
The three parts of a pre-existing condition rule
Most rules have three pieces. Find each one in the guidelines:
- The definition. What counts as pre-existing? Usually any condition with signs, symptoms or treatment within a "look-back" window before you joined.
- The look-back window. How far back do they look? It may be different for cancer.
- The phase-in. How much, if anything, is shared in year one, year two and after?
A real example: America's HealthShare
Here's how America's HealthShare's sharing guidelines (opens in new tab) handle it, as published when we checked:
Definition. A pre-existing condition is (a) a condition with signs, symptoms or treatment in the 24 months before applying, (b) any cancer with signs, symptoms or evidence of disease in the 60 months before applying, or (c) a condition reasonably expected to need medical intervention in the future.
Phase-in:
| Membership period | Sharing for pre-existing conditions |
|---|---|
| Months 1–12 | Not eligible |
| Months 13–24 | Eligible up to $25,000 |
| Months 25–36 | An additional $25,000 may be eligible |
| Month 37 onward | No longer treated as pre-existing |
The same guidelines say the ministry may decline applicants with active, pre-existing medical needs, and that for the first 60 days of membership sharing is limited to accidents, emergencies and acute illness.
The exception is America's HealthShare's COMPANION program for people 65 and older on Medicare Parts A and B, where the guidelines say pre-existing condition limitations don't apply. See our COMPANION guide.
How to compare programs on this point
- Ask for the exact definition, not a summary.
- Note whether maintenance care such as prescriptions for a controlled condition is treated differently.
- Check whether the phase-in resets if you change programs or sharing levels.
- Answer the medical history questionnaire completely and honestly. Leaving things out can cause bills to be ruled ineligible later.
When insurance is probably the better choice
If you need care soon, read how fast a health share can start for Marketplace and Medicaid start dates.
If you're managing a chronic condition, expecting surgery or in active treatment, a year-one exclusion can mean paying every related bill yourself. In that case, compare ACA plans and any subsidies on HealthCare.gov (opens in new tab) before choosing a health share.
Frequently asked questions
Do health shares cover pre-existing conditions?
Health shares don't provide coverage, and they aren't required to share pre-existing conditions the way ACA insurance must cover them (NAIC (opens in new tab)). Many phase in limited sharing over several years of membership.
How long is the look-back period?
It varies. America's HealthShare's guidelines use 24 months for most conditions and 60 months for cancers (guidelines (opens in new tab)). Check each program's definition.
Can a health share turn me down because of my health?
Yes, it can. America's HealthShare's guidelines say the ministry may decline applicants who present active, pre-existing medical needs (guidelines (opens in new tab)).
Should I leave insurance for a health share if I have a chronic condition?
Be very careful. Because sharing for pre-existing conditions is usually limited, people with ongoing care needs may face large unshared bills. Compare ACA plans, including any subsidies, on HealthCare.gov first.
Is there a health share with no waiting period for pre-existing conditions?
Among America's HealthShare programs, only COMPANION (65+ on Medicare Parts A and B) has no pre-existing condition limitation (guidelines (opens in new tab)). Its main programs don't share pre-existing conditions in year one.
