Following up a February study, which showed that people needing drugs on the highest formulary tier will pay much higher out-of-pocket costs than other ObamaCare enrollees, consultants at Avalere have released another study, which shows that the low-income ObamaCare enrollees will suffer this effect even more than middle-class ones.
A formulary is a list of drugs that a health plan covers. It can be divided into up to four tiers. Drugs on the lowest tier (usually generic medicines) cost the least out of pocket, while those on the highest tier cost the most. However, those on the highest tier are the most expensive, and often indicated for those suffering the worst diseases.
