Young men who aren’t insured through their employers may end up bearing the brunt of new costs under the Affordable Care Act (ACA) due to policy changes.

Here are four provisions of the ACA that may be responsible for premium increases for young men:

Age Limits for Health Costs Will be Removed

Currently, older Americans who are more likely to suffer health issues are charged up to five times more than young adults. The ACA will limit the amount insurers can charge older enrollees up to three times the amount being charged to younger enrollees. This change will result for higher premiums for some young adults and lower premiums for some older adults.

Insurers Cannot Charge More for Pre-Existing Conditions

Individuals with pre-existing conditions can no longer be excluded or charged higher rates for insurance coverage. While those who have been sick now have access to more affordable plans, the overall cost of coverage could become more expensive for healthy people.

Gender Price Differences Will be Erased

Previously, insurers could charge individuals based on their gender. Since women tend to visit the doctor more frequently than men, men typically enjoyed lower premiums than women. But, with the ACA comes a change that requires health insurers to charge men and women the same amount.

Additional Benefits for Women in Health Plans

The ACA also requires the additional of new essential benefits and maternity benefits in all health plans. For example, all health plans will now require maternity benefits even though men will not utilize those benefits, they will be paying for those benefits.

The exact change in health plans costs for young males will not be known until the summer or during open enrollment in the fall.
