Ridgeline Family Medicine-Castle Pines

Primary Care First

We are Participating in a New Program to Enhance Your Care: Primary Care First

Primary Care First is an innovative healthcare payment program that aims to improve our patients’ care experience by reducing administrative burdens, so our team can spend more time with you.

Giving doctors extra support to help you get better care

Our goal has always been to provide you with the highest quality of care. Through Primary Care First, we will receive additional resources from Medicare and other health insurance companies to help us enhance our work and provide you the best quality, patient-centered care.

More information for patients with original Medicare

As part of this program, Medicare will start sharing some of your personal health information with us, such as when you receive care at hospitals, emergency departments, and specialist offices. This will help provide us with a more complete picture of your health and allow us to better coordinate your care.

If you want to stop Medicare from sharing this information, you should call
1-800-MEDICARE (1-800-633-4227). TTY users should call 1-877-486-2048.

Your Medicare benefits are not changing, and this program is only intended to enhance the healthcare you receive at our location You still have the right to use or visit any doctor or hospital that accepts Medicare, at any time. Your doctor may continue to recommend that you see particular doctors for your specific health needs, but it is always your choice which doctors you use or hospital you visit.


If you have questions or concerns, you can call your doctor, or bring it up at your next appointment.
