Our Services

Participation in a California medical provider network (MPN) is an important component of a medical cost containment strategy as it allows employers better control over the care of the injured worker. For any insurer in California, care for the injured worker, control for the duration of the claim, access to quality medical services, and medical provider discounted rates are all important to decrease employee downtime and return back to work at a financially advantageous amount to the company. 

An MPN is a group of health care providers used by employers to treat employees injured on the job. In California, the MPN must meet certain requirements including being able to treat injuries in a timely manner, having close access to care, providing an adequate mix of physicians and medical facilities specializing in workers' compensation cases, and for the in-network providers to offer treatment at reasonable times to all employees. 

Prime Health Services currently offers its clients access to California medical provider networks (MPNs).
