Check your drug: what each 2027 FEHB and PSHB plan charges by tier
Federal Benefits Open Season for plan year 2027 runs November 9 to December 14, 2026.
* Nine FEHB plans end after 2026. If you are in one and do not pick a new plan by December 14, OPM enrolls you in Compass Rose Standard. See the nine- Look up your drug in a plan’s drug list (the button on each plan) and note its tier.
- Pick that tier here. Every plan shows what one fill costs on it, and the brochure’s own words if it names your drug.
A drug can sit on a different tier in each plan. Change the tier on any plan below to match that plan’s list. The drug name and price you type stay on this device; nothing is saved or sent.

How the figures are built
From OPM’s 2027 plan files: each plan’s summary for Tier 1 to Tier 4. Where we read the plan’s brochure for a per-fill limit (a percent up to a dollar cap), the brochure’s figure is shown with its page. Where a brochure states no limit, the page says so. In a high-deductible plan the deductible comes first.
Searched in each 2027 brochure’s changes for 2027, its prescription drug benefits, and its exclusions, quoted word for word with the page. Brochures name kinds of drugs (insulin, inhalers, biologics, contraceptives) far more often than brand names, so a brand you take may not appear. That says nothing about coverage: the drug list decides.
A plan’s Medicare drug plan has its own prices and list. This page reads the plan’s regular drug benefit only. The GLP-1 pages show each brochure’s Medicare drug plan passages for weight-loss drugs.
Before you decide
The plan decides coverage and claims under its brochure, and your employing office handles eligibility and enrollment. If a plan denies a claim, the brochure’s disputed claims section shows how to ask the plan to reconsider and then ask OPM to review it. Every brochure says it: “This brochure is the official statement of benefits.”
A drug’s tier, prior approval, step therapy, and quantity limits are set by each plan’s drug list, which can change during the year. The per-fill figures here are estimates from the plan’s own summary; your pharmacy and the plan’s drug price lookup give the real price. StandWatch is independent, does not act for OPM or any agency, and is not paid by any plan or drug maker. Full disclosures
