“My letters come from CorVel. Who are they?”

Who CorVel is

A workers’ comp claims management company. CorVel’s website lists workers’ compensation claims management among its services, and its California page says CorVel received certification for its California medical provider networkMPN Medical Provider Network. Your employer’s list of physicians. After the first visit you may switch within it without permission. in January 2005.

It is on the state’s list. The Office of Self-Insurance Plans’ list of third-party administrators, dated July 31, 2026, includes CorVel Enterprise Claims, Inc., with California locations in Rancho Cucamonga, Irvine, San Diego and Folsom. A company that administers or adjusts self-insured employers’ claims must hold a Certificate to Administer, with listed exceptions.

What that means for your claim

CorVel runs the claim. It does not fund it. A third-party administrator is an agent under contract to administer the claims of an insurer, a self-insured employer, a legally uninsured employer or a self-insured joint powers authority. The benefits are paid with the money of whoever hired it.

The examiner works for the payer, not for you. Every benefit notice must tell you that you have a right to disagree with decisions affecting your claim and a right to be represented by an attorney of your choice.

Your benefits do not change. The Labor Code’s benefits and deadlines apply the same way whoever administers the claim. Who is handling my claim?

How to reach your adjuster

Start with the notice. Every benefit notice must show your claim number and the name, telephone number and mailing address of the individual claims examiner responsible for your claim. Write to that person, and put the claim number on everything you send.

Which medical network applies

DWCDWC Division of Workers’ Compensation, part of the Department of Industrial Relations. Administers the system. Information Services Center: 1-800-736-7401.’s list names five CorVel networks. DWC’s list of active Medical Provider Networks, as of July 8, 2026, shows CorVel Healthcare Corporation as the applicant for the CorVel MPN (MPN ID 3130), the CorVel Kaiser Select MPN (3145), the Cast & Crew MPN (3216), the Stater Brothers MPN (3226) and the Sharp MPN (3229).

Other networks carry CorVel’s name but belong to someone else. The County of Los Angeles, listed as a self-insured employer, is the applicant for the County Of Los Angeles/CorVel MPN (0060). Travelers Property Casualty Company of America, listed as an insurer, is the applicant for the CorVel/Express MPN (3039).

So the name does not tell you which network is yours. An insurer, an employer, or a company that provides physician networks may set up an MPN. Yours is the one your employer or its insurer uses.

Your MPN notice tells you. When an injury covered by an MPN is reported, the employer or its insurer must give you a complete written MPN notification, in Spanish as well if you primarily speak Spanish, with the MPN’s identification number, toll-free telephone access to the MPN contact, and the MPN website. If you never received one, ask for it in writing. How the MPN works
