Blue Cross to cover annual mental health wellness exam
February 15, 2024

This article is for the mental health and primary care providers who care for our members

Starting March 31, 2024, Blue Cross will cover an annual mental health wellness exam as required by the Addressing Barriers to Care Act (ABC Act) to improve mental health care across Massachusetts. This exam may be conducted as part of the annual preventive visit with a primary care provider (PCP), or as a standalone visit with a primary care provider or licensed mental health professional.

Because the mental health wellness exam is considered preventive care, there is no out-of-pocket cost for members in most plans.

What is the mental health wellness exam?

The exam includes taking the patient’s mental health history, appropriate screening tests, shared decision-making (that could include lifestyle education and counseling) and a discussion about next steps such as referrals for treatments and medication options. The mental health wellness exam may or may not result in a diagnosis.  

Who may administer the exam

  • A Massachusetts licensed mental health professional
  • A Massachusetts primary care provider, including OB/GYNs, as a separate exam or as part of the annual wellness visit.

How to bill for the exam

We will reimburse claims submitted with dates of service on or after March 31, 2024 that contain the following procedure and diagnosis codes. To ensure that members are not subject to out-of-pocket cost, bill with modifier 33 in the first modifier field on your claim to indicate that the evaluation is for preventive purposes.
