Work Comp Prescription
A workers’ compensation drug formulary is a list that determines which medications can be dispensed on a work injury claim without additional approval. It exists to steer prescribing toward evidence-based, lower-risk options, and in practice it is the single most common reason an injured worker’s prescription gets held up.

Closed and open formularies
The distinction matters more than any other detail on this page.
- A closed formulary lists the medications that are approved, and anything outside the list needs preauthorisation before it will be paid. In states with a closed formulary, prescribing off-list without submitting justification reliably produces a rejection.
- An open formulary places fewer restrictions up front, with control applied through treatment guidelines and utilisation review after the fact.
- Some states operate neither, and rely on treatment guidelines and utilisation review alone.
Most closed formularies are built on published evidence-based treatment guidelines rather than written from scratch, and most flag certain drug classes, commonly opioids, compounds and some psychotropics, for additional scrutiny regardless of where they sit on the list.
The exception process is the important part
A medication being outside the formulary is not a refusal. Every closed formulary system has a route to approve an off-list drug when the prescriber can justify it. What varies is what the submission must contain, how long the carrier has to respond, and what happens if they do not respond in time.
That pathway is where prescriptions are won or lost.
What this means in practice
For prescribers
Check the formulary position before prescribing rather than after the rejection, and if an off-list medication is genuinely the right choice, submit the justification with the prescription instead of waiting for the refusal.
For adjusters
A formulary rejection is usually a documentation gap rather than a clinical dispute, and the fastest resolution is normally a direct conversation with the prescribing office.
For injured workers
If you have been told your medication is not covered, it does not mean you cannot have it. It usually means your doctor needs to submit a short justification. Our team identifies this and starts that process rather than handing the prescription back.
FAQ
What is a workers’ comp drug formulary?
A list determining which medications can be dispensed on a work injury claim without extra approval. Medications outside it typically require preauthorisation with clinical justification.
What is the difference between a closed and an open formulary?
A closed formulary approves only listed drugs and requires preauthorisation for anything else. An open formulary restricts less up front and controls through treatment guidelines and utilisation review instead.
My medication is not on the formulary. Can I still get it?
Usually yes. Every formulary system has an exception route where your prescriber submits justification. We identify when this is needed and start the request.
Does every state have a workers’ comp formulary?
No. Some states operate a closed formulary, some an open one, and some rely on treatment guidelines and utilisation review. Check your state’s page.
