It is your employer's goal to provide you a safe working environment. Keeping you well and fully employed is the first priority. However, should you become injured at work, your employer and MEDEX will work with you to remedy your injury or illness so that you can return to your job as soon as possible. California law requires employers to pay for all appropriate medical treatment for on-the-job injuries. MEDEX will be there for you to make sure that you receive the appropriate medical treatment.

MEDEX will assist you and your claims examiner in assigning a Primary Treating Physician (PTP) to treat your work place injury or illness. If a specialist is needed, your Primary Treating Physician will send you to an appropriate specialist and continue to coordinate your medical care.

What is an HCO and MPN?

An HCO (Health Care Organization) and MPN (Medical Provider Network) are networks of quality medical providers who are proficient in working with work-related injuries or illnesses. Based on our years of experience in the Workers’ Compensation healthcare field, MEDEX has identified the best physicians who are properly licensed, credentialed, and experienced in the Workers’ Compensation system so injured workers get prompt, quality care. Your employer has worked with MEDEX to identify a clinic or urgent care facility location that can provide initial medical care should you be injured at your workplace. Your supervisor or manager must be notified of any workplace injury or illness and will provide you with the designated clinic location(s) where you should go for medical treatment.

Did you experience a work-related injury or illness?

In the event you experience a work-related injury or illness, follow these steps:

Step 1 - Notify Your Employer

Report any work-related injury or illness to your supervisor right away.

Step 2 – Find Your Network

Ask your employer for the designated clinic location and/or your HCO/MPN network name. This is often posted on the employee breakroom wall along with other HR-related postings.

Step 3 – Find Your Provider

Click your employer’s link or your designated HCO/MPN network for your place of work and search for a provider within that medical provider network (MPN).

For Urgent Care

For urgent problems such as fractures, cuts, or minor allergic reactions go directly to your MEDEX medical provider or to an urgent care facility.

For Emergency Care

In the case of emergency, which is defined as a need for those health care services provided to evaluate and treat serious medical conditions of recent onset and severity that would lead a prudent layperson, possessing an average knowledge of medicine, to believe that emergency care is required, go to the nearest healthcare provider regardless of whether they are a participating provider with MEDEX. Once your condition is stable, contact your employer or MEDEX to assure your continued care.

For Non-Emergency Specialty Care

All non-emergencies that require in-depth medical testing or a rehabilitation program must be authorized by your MEDEX medical provider.
