A bill that makes it harder for insurance companies to deny coverage for mental healthcare passed in the Colorado House on Monday. Under federal law, insurers are required to treat physical and mental health care in the same way, but state Sen. Judy Amabile, the sponsor of the bill, says that many insurers are refusing to cover mental health care based on what their definition of what's medically necessary. The Democrat from Boulder County's bill would establish a standard definition of medical necessity based on criteria developed by mental health professionals.
