Medicare Part D and CalOptima Health OneCare (HMO D-SNP)
With CalOptima Health OneCare (HMO D-SNP), the costs of your Medicare Part D medicines stay low. We created our full list of medicines (or “formulary) to meet your health care needs. With no or a very low copay from you, we’ll cover the rest of the cost of your medicines as long as:
- The medicine is medically necessary
- The prescription is filled at a network pharmacy
- Other plan rules are followed
Some of your medicines might need to be approved before you can get them (called “prior authorization”). You might also need to do “step therapy,” or try certain medicines to treat your condition before we cover another medicine for it.
Medicines We Cover
Our OneCare Complete and OneCare Flex Plus options each have their own formularies with all the medicines you need as well as clear guidelines for prior authorization and step therapy:
