California has more than 13,000 physician groups that range from having a single-digit number of physicians to more than 4,000 members. As it stands, California is the state with the greatest number of physician group practices.

Examining data on a physician group can provide powerful insights into its productivity, challenges, and strengths. One important metric is the physician group’s Medicare charges, which can illuminate the group’s overall productivity regarding how many patients they treat and the relative cost of their procedures.

Which California physician group has the most Medicare charges?

The California physician group with the moston Medicare charges, is Prospect Medical Group, which has more than $2.3 billion in total charges. This physician group based in Orange has over 3,800 physicians within its network and coordinates directly with medical groups, physicians, medical labs, urgent care centers, hospitals, and radiology centers.

The second-largest physician group in California is UCLA Health System Physicians, with over $2.27 billion in Medicare charges. They offer an integrated network of both primary and specialty care services, with more than 280 clinics within their network and five medical centers and hospitals. The physicians within this group contribute to the continual ranking of UCLA Health by U.S. News & World Report as the #1 hospital in California for patient care.

Finally, Cedars-Sinai Physicians, located in Beverly Hills, rounds out the top three highest-earning California physician groups with $2.25 billion in Medicare charges. These physicians specialize in various services, including pediatrics, cardiology, oncology, and obstetrics & gynecology.

Physician groups with high Medicare charges likely see more patients or perform more advanced—and therefore more expensive—procedures than others. Looking at a physician group’s Medicare charges can identify the entities that may be wise targets due to their high patient volumes, high revenue, and growing need for quality healthcare services and products.

Why target physician groups with your healthcare sales strategy?

Physician groups are a critical component of the healthcare space because of their ability to bring physicians together, often under one specialty or location. They are typically owned by health networks, but in some cases, they may be owned by academic organizations or be independently owned by the physician members that make up the group.

Bringing together physicians can offer numerous benefits not only for their patients, who see better care, but also for your company should you choose to target them with your sales and marketing.

When targeting physician groups, you can see the rollout of your product, technology, or service at their many locations, allowing your company to have a greater impact on the healthcare industry without having to market to each place and physician separately.
