Permits payment of only one co-payment or deductible for follow-up care or treatment after surgery or illness under certain health benefits plans.

This bill (S 4187) requires health insurance plans to allow patients to pay only **one co-payment or deductible** for all follow-up care visits related to surgery, illness, or other covered services within an **180-day period**. It directly affects **patients enrolled in managed care health plans** who need ongoing treatment after an initial procedure or diagnosis. The key provision prevents healthcare providers from charging additional co-pays or deductibles during that 180-day window, regardless of how many follow-up visits occur. The rule applies only if patients follow their plan’s preauthorization rules for in-network care.
