Overview

Medical Provider Overview

Am I Covered?

You are automatically covered by the MPNs if your date of injury or illness is on or after the County’s implementation date; and, if you have not pre-designated a personal physician prior to your injury or illness.

The County has elected to provide you with the choice of a broad range of medical services for work-related injuries and illnesses by implementing three MPNs. You may choose a provider from any of the three MPNs.

The MPNs are ready to provide quality medical care through your choice of a provider who is part of a pre-qualified network of physicians, each possessing a clear understanding of the State of California Workers’ Compensation system and its decision-making impact on you.

The County has received approval from the State of California to provide your Workers’ Compensation medical care needs through its MPNs.

In Case of Injury

When an occupational injury occurs, contact your supervisor immediately, and if you are not pre-designated, ask for assistance to access an initial treatment center.

For Emergency Treatment

If you have an emergency, which is defined as a medical condition starting with a sudden onset of severe symptoms that without immediate attention could place your health in serious jeopardy, go to the nearest healthcare provider regardless of whether or not it is in the County’s MPNs.

If your emergency injury is work related, advise your emergency care provider to contact your supervisor to arrange for a transfer of care to a provider in the County’s MPNs.

For Hospital and Specialty Care

If necessary, your primary treating physician in the MPNs will make all of the arrangements and referrals for specialists, inpatient hospital, outpatient surgery center services and ancillary care services.

The MPNs have specialty care providers within 30 miles or 60 minutes from your work or residence, pursuant to Section 9767.5.

For Appointments

If you have any difficulty scheduling an appointment with your initial provider or subsequent provider, please contact your supervisor or your department’s return to work coordinator.

Frequently Asked Questions

What is a Medical Provider Network (MPN)?

An MPN is a network of medical providers such as physicians and hospitals that have been certified by the State of California Division of Workers’ Compensation, to provide health care to injured workers. It mandates treatment by those providers unless an employee has pre-designated their treating physician prior to a work related injury. In the case of an emergency, employees are encouraged to seek the nearest medical emergency services.

Why do I have to go to a County Doctor?

As referenced in the answer portion of # 11 above, the purpose of the MPNs is to provide the same quality care and help contain overcharging in the Workers’ Compensation system. The MPNs are not made up of “County Doctors”, but professional health care providers who also provide their services to the public and other entities.

Why are the procedures for workers’ compensation being changed?

The passage of SB899 allows self-insured employers like Los Angeles County to offer MPNs. Labor Code section 4600 provides that medical provider networks may be established by employers or insurers on or after Jan. 1, 2005. The standards must also include a process for allowing employees a choice of medical provider in the networks (after the first visit) and for getting second and third opinions.

If an employer or insurer uses medical provider networks, covered employees would receive their medical care in those networks, unless a predesignated physician is chosen prior to an injury. Medical provider networks must be approved by DWC before they can be used.

How do I access a list of the MPN providers?

You can access the County’s MPNs to choose an initial and/or on-going treatment provider within the MPNs by clicking the “Initial Treatment Centers” or “Provider Network” in the navigation section of this website (to the left of your screen).

I live in a rural area outside of Los Angeles County. How do I get treatment?

The County is required to provide occupational health providers within 30 minutes or 15 miles of an employee’s residence or workplace. If you live outside of that service area, a provider will be found for you, so that the required treatment guidelines are followed. If you need assistance, please contact your Third Party Administrator (TPA), Return-To-Work (RTW) Coordinator, or the Chief Executive Office (CAO) Disability Management Unit, for assistance.

How do I change physicians?

After your initial referral, you can change treating medical providers within the MPNs. If you have a recurring treatment, a letter should have been provided to you that explained the process for changing physicians.

This process is available online at the County of Los Angeles MPNs website (this website) or you may go through your department’s RTW Coordinator.

Can I choose a physician that I have not treated with to be my predesignated doctor?

No, your predesignated physician must have treated you before your work related injury or illness and must maintain your medical records.

What if I don’t agree with the treatment recommended by the medical provider on the County’s MPNs?

If you dispute treatment or diagnosis, you can request a change of medical provider during the course of your medical treatment. Your request must be made to your TPA.

What if I need immediate non-emergency treatment?

The County is required to provide an appointment for initial treatment within three days of receipt of the claim for non-emergency treatment. Therefore, for non-emergency treatment, you must wait until business hours to receive your initial treatment and initial referral to the County’s MPNs.

I don’t trust the County, how can I be sure they are not going to send me to a biased medical provider?

The State of California has formulated strict rules per the California Labor Code that the County must abide by for setting-up and maintaining it’s MPNs. Specifically, the County cannot offer the doctor any compensation to delay or deny a claim.

Since all treatment must be compliant with the ACOEM guidelines, the treatment standards are built into the County’s MPNs to assure employees quality medical care. There are over 40,000 medical providers in the County’s MPNs and all are certified based upon California State standards.
