Usually yes for maintenance medications - Medicare's guidance confirms plans may offer 2- or 3-month supplies at retail and up to 3 months through mail order, and commercial plans mirror the pattern.
The wins: money (90-day fills often price below three monthly copays), friction (four fills a year instead of twelve - adherence quietly improves), and resilience (a buffer against refill hiccups, travel, shortages). Expect exceptions: controlled substances stay short-capped, new prescriptions start with 30-day trial fills, and refrigerated or specialty drugs have their own rules. Setup: prescriber writes for 90-day quantity with refills, then ask the plan whether mail order or a preferred retail pharmacy prices it better - five minutes, real money.

What to do
Common questions
Can I get a 90-day supply of my medication?
Usually yes - if your medication is a maintenance drug (something you take daily for months or years: blood pressure, cholesterol, thyroid, antidepressants, birth control), most insurance plans offer 90-day fills, and the route matters less than asking. Medicare's own guidance confirms plans may offer 2- or 3-month supplies at retail pharmacies and up to a 3-month supply through their mail-order programs; commercial plans mirror the pattern. The three wins: money - many plans price a 90-day fill at two or two-and-a-half copays instead of three; friction - four pharmacy trips a year instead of twelve, which quietly improves adherence; and resilience - a buffer stock when refills, travel, or shortages hit. The exceptions to expect: controlled substances are capped shorter by law and plan rules, new prescriptions usually start with a 30-day trial fill (plans will not fund three months of a drug you might not tolerate), and refrigerated or specialty drugs follow their own rules. How to set it up: ask your prescriber to write the prescription for a 90-day quantity with refills, then ask your plan whether the cheaper route is its mail-order service or a preferred retail pharmacy - the answer varies and is worth the five-minute call.
