The evidence is adequate to conclude that screening for chlamydia, gonorrhea, syphilis and hepatitis B, as well as high intensity behavioral counseling (HIBC) to prevent STIs is reasonable and necessary for the prevention or early detection of an illness or disability. Therefore, CMS will cover screening for these indicated STIs with the appropriate laboratory tests when ordered by the primary care physician or practitioner. In accordance with CMS guidance, Humana will now allow for these preventive services.
