Routine HIV Screening Coverage Act of 2009 - Amends the Public Health Service Act, the Employee Retirement Income Security Act (ERISA), and the Internal Revenue Code to require a group health plan to provide coverage for routine HIV screening under terms and conditions no less favorable than for other routine screenings. Prohibits such a plan from taking specified actions to avoid the requirements of this Act. Applies such requirements to health insurance coverage offered in the individual market and coverage offered under the Federal Employees Health Benefits Program (FEHBP).
