How is Surest different for health care providers and patients?
Surest tries to simplify health care and cut through the confusion by:
- Offering clear, upfront pricing: Members know prices in advance and may be less likely to delay, forego or ration their medical care or medications.
- **Providing options:**Members can see what’s covered and compare costs between providers. They have the ability to see high-value provider options that may not have been visible before.
- Offering the flexibility to activate coverage if the need arises.
More clarity and a better experience for your patients means less ambiguity for you, the provider:
- Members know what they'll owe, improving the collection process.
- Prices that members see are the prices they pay their providers.
- There’s no need to reconcile claims based on deductibles.
