Healthcare insurance, if you’re lucky to have it, only covers a subset of conditions in the United States. As a result, patients can often get burdened with horror story charges, like huge deductibles, out-of-network costs and expensive co-pays. So for the uninsured and insured alike, innovative ways of managing big bills are in high demand — especially as uncertainty remains around how COVID-19 and long-haul symptoms will be handled by patients and payers.

Walnut, founded by Roshan Patel, is a point-of-sale lending company with a healthcare twist. Walnut uses a “buy now, pay later” model, popularized by Affirm and Klarna, to help patients pay for healthcare over a period of time, instead of in one $3,000 chunk. Walnut works with healthcare providers so that a patient’s bill can be paid back through $100-a-month increments for 30 months, instead of one aggressive credit card swipe.
