Enter a Los Angeles County ZIP to see medical groups and IPAs people in that area may hear at the doctor’s office. Use it as a starting list, not a final answer.

Write down the names that look familiar. Take them to your doctor’s front desk and ask: “Is this doctor in this medical group this year, and which Medicare plans do you accept at this location?” Then confirm those same names with the plan and on Medicare.gov before you change coverage.

After you have a few names, take them to My Medicare Checkup. The questions there are for the doctor’s office and the insurance carrier.
