The physicians survey is nonrepresentative but offers insight into areas for improvement

• The physician survey in spring 2017 yielded a low response rate and a sample of 225 WC providers.
• The most common reasons for limiting new WC patients were (1) issues with authorizations and utilization review (UR) denials (46 percent), (2) paperwork and/or administrative issues (39 percent), and (3) payment levels (23 percent).
• The majority of physicians reported requesting authorization for treatment, but most reported lacking easy access to the medical treatment guidelines.

Medical Provider Networks (MPNs) include many of the same physicians

• An analysis of 146 MPNs participating in the California WC system found an average network size of 6,317 providers in 4,176 locations.
• Provider participation in an MPN does not necessarily increase the underlying supply of providers available to injured workers.

Trends in providers, utilization, and payments remain relatively stable

• The number of providers and the number of total claims filed each year was relatively stable: 69,728 providers and 846,649 medical claims in 2012 relative to 72,790 providers and 843,162 medical claims in 2015.
• Utilization and payments were relatively stable across most provider types, except acupuncturists, occupational medicine physicians, and physical therapists, all of whom experienced statistically significant increases in the number of claims per provider, the number of services per claim, and the total annual WC reimbursements.
• WC bills decreased for prescription drugs, medicine, surgery and durable medical equipment, while the bills for "other or unknown" service types increased.
