It often provides more coverage than a health insurance policy.
With medical payments coverage, you are only covered for medical bills and funeral expenses. If you have both medical payments coverage and personal injury protection, your PIP would act as primary coverage and your medical payments would be secondary.
In most states, you won’t be required to carry both nor have the option to. Most no-fault states require that you carry PIP and typically won’t give you an option for medical payments coverage. Other states may only offer medical payments as an additional coverage.”
