If you’ve been diagnosed with Diabetes, Cardiovascular Disorders and/or Chronic Heart Failure, you’re eligible to join the Central Health Focus Plan (HMO C-SNP).

If you’re enrolled in Medi-Cal icn-material-info-outline, you may be eligible for our Medi-Medi Plan HMO D-SNP or Ventura Medi-Medi Plan HMO D-SNP.

If you meet the eligibility requirements above, you can enroll in one of our plans:

Important Information

To enroll in any Central Health Plan, you will need to provide your current Medicare Member Number (on your Medicare card) and your permanent address and phone number. Please note that you must complete all items in sections marked “Required.” All other sections are optional and you cannot be denied coverage because you don’t fill those out.

Once you’re enrolled, we will send you a bill for the plan’s premium. You may also choose to have your premium payments deducted from your bank account or your monthly Social Security (or Railroad Retirement Board) benefit.
