What this means in Hillsborough County
52 plans from 15 insurers makes Hillsborough County one of the most crowded markets in Florida (state county average: 28.7). Cut the list by doctors and prescriptions first, since a plan that leaves out either is not a fit at any premium. More insurers means more provider networks to check against your doctors. Fewer PPO-type plans than usual means network fit matters more here. 90% of the plans (47 of 52) charge no monthly premium, so premium will not separate most of them. The out-of-pocket maximum, $1,000 to $9,850, shows what a bad year could cost. A $0 premium does not remove copays or coinsurance, and your Part B premium is separate.
The list mixes 33 HMO-style and 19 PPO-style plans, so network rules differ from plan to plan; read each plan's provider rules. 39 of the 52 rated plans have 4 or more stars. CMS rates the insurer's contract, so look up the rating of the specific plan you are considering.
How to compare plans in Hillsborough County
- Doctors and hospitals. Ask each plan whether your doctors, your hospital and any specialists are in its network today. 33 of 52 plans here are HMO or HMO-POS and 19 are PPO-type, so the rules differ.
- Prescriptions. 41 of 52 plans include drug coverage. For each drug, check the plan's formulary, the tier it sits on and the pharmacy you would use.
- Out-of-pocket cap. The in-network maximum runs $1,000 to $9,850 a year depending on the plan, a gap of $8,850. The cap is what limits a hospital stay or a run of treatments.
- Extras and cost-sharing. Compare copays for primary care, specialists and the emergency room, and any dental, vision and hearing benefits you would use.
- Star rating. 39 of the 52 rated plans have 4 or more stars. Ask for the rating of the exact plan, then see how it handles the doctors and drugs above.
