PBMs commonly handling Texas WC claims

The pharmacy benefit manager handling your claim depends on which insurance carrier (or third-party administrator) your employer uses. The major WC PBMs operating in Texas include:

• Optum Workers' Comp (formerly Helios) — Largest WC-only PBM by claim volume.
• myMatrixx (formerly Express Scripts) — Long-tenured WC PBM, owned by Cigna/Express Scripts.
• Mitchell ScriptAdvisor — Integrated with Mitchell's claims/medical bill platform.
• Healthesystems — WC-specific PBM with strong utilization review.

Your claim paperwork lists the PBM by name. If you can’t find it, ask your claims adjuster directly.

Frequently asked questions

How do I get a workers' comp prescription filled in Texas?

Bring your WC claim number, the claims adjuster's contact, and your prescription. Tell the pharmacist it's a workers' comp prescription — they'll bill the carrier's pharmacy benefit manager (PBM) directly. You should not be asked to pay at the counter. If the pharmacy isn't a contracted WC pharmacy or the drug requires prior authorization, the script may go on hold. Call your adjuster.

Which pharmacy benefit manager does my Texas carrier use?

Your claim paperwork or the adjuster will identify the PBM. The major WC PBMs operating in Texas include Optum Workers' Comp (formerly Helios), myMatrixx, Mitchell ScriptAdvisor, and Healthesystems. The PBM determines which pharmacies are in network and runs the utilization-review/prior-authorization process.

What if my drug isn't on the DWC Closed Formulary?

Your prescriber has to submit a prior authorization request explaining medical necessity. The carrier (through its PBM) has a statutory window to decide. If denied, the denial can usually be appealed through the state's utilization-review dispute process. See your claims adjuster or a workers' comp attorney for the appeal mechanics.
