The published price list a state sets for workers’-comp services. Where one exists, it decides what you are paid. Where it does not, your engagement letter does.
A fee schedule is the rate table a state publishes for services billed to workers’ compensation. For vocational rehabilitation the picture varies more than most people expect:
Current as of July 2026 — verify with the agency before billing from any figure.
Schedules move. Ohio’s changes each October; Minnesota indexes annually. New work bills at the new rate — and work you already performed keeps the rate that applied on the date of service, which is how an audit expects to find it.
That is why a spreadsheet with one hard-coded rate column goes quietly wrong every year, and why a rebill of an old short-paid line should carry the old rate, not today’s.
In a no-schedule state the discipline moves rather than disappears: write the rate, the billing increment, travel, wait time and mileage into the engagement before the first hour, and keep the rate per payer rather than per practice.
The Ohio W-code reference is the worked example, and the state billing guides carry each state’s rate basis with its verification date.
