Our Story

Gold Kidney Health Plan was created by nephrologists to improve health outcomes for those with End Stage Renal Disease or conditions that lead to chronic kidney disease.

Our Team

Gold Kidney leaders are passionate about what they do and committed to creating a better standard of quality care for patients with chronic health conditions.  


Our employees are a vital part of delivering on our promise to provide a gold standard of care by providing a more personalized and holistic approach to healthcare.  

Our Story

Our story began by listening to patients with chronic diseases. Patients have been telling their doctors that they cannot afford necessary treatments for their chronic conditions due to the limited availability of Chronic-Special Needs Plans in the market. Over 100 nephrologists decided to take actions and started Gold Kidney Health Plan.

The goal is to provide the needed coverage for patients with chronic diseases. Gold Kidney reduces patients’ cost share by offering Chronic-Special Needs Plans that offer low to no member costs for select treatments for chronic conditions.

Our care model is simple: removing patients’ barriers to care by empowering our physician partners to have full authority to direct the care for our chronically ill members.

Gold Kidney’s patient-centric care approach integrates payor, provider, and care management technology to effectively improve patient outcomes and quality. At Gold Kidney, the patient’s well-being is our number one focus and priority.
