Under the ACA, many people are now able to access preventive health services without any cost-sharing. This means that you can get these services without having to pay a co-payment, coinsurance, or a deductible (when you see an in-network provider).
If you receive preventive services as part of an office visit, the primary purpose of which is not the preventive service, you might still have to pay some of the cost of the office visit. This is also true if your doctor bills the office visit and the preventive service separately.
Please note that this rule applies to non-grandfathered plans (“grandfathered” plans are plans that have existed since before March 23, 2010 without changing significantly).
