Does Blue Cross Blue Shield of Illinois cover ABA therapy in Illinois?

Illinois's autism insurance mandate (215 ILCS 5/356z.15, 2011) requires state-regulated fully-insured commercial plans to cover autism diagnosis and treatment, including ABA, for individuals under 21, with benefits up to $36,000/year (inflation-adjusted) at parity with other medical benefits. Blue Cross Blue Shield of Illinois covers ABA therapy under this mandate for its state-regulated plans. If your BCBS plan is employer-based, it may be self-funded, in which case the state mandate may not apply — call BCBS Illinois directly to confirm your plan type. Note on Medicaid: BCBS Community Health Plan is BCBS Illinois's Medicaid managed care plan and covers Adaptive Behavior Support (ABS) services for individuals under 21 with an ASD diagnosis. This is a separate product from the commercial BCBS Illinois plans covered on this page.

What does Blue Cross Blue Shield of Illinois require before ABA therapy starts in Illinois?

Prior authorization is typically required before ABA services begin:

  • DSM diagnosis of F84.0

    A DSM diagnosis of F84.0 (autism spectrum disorder) is a prerequisite — without it, ABA assessment or service authorizations cannot be granted.

  • Prior authorization process

    Prior authorization typically involves a diagnosis, physician referral, and a BCBA-developed treatment plan. Approval commonly takes up to 14 business days for the initial assessment, plus another 14 days for authorization of ongoing direct services.

  • Assessment codes (reduced prior auth)

    As of September 1, 2022, BCBS Illinois eliminated the prior authorization requirement for CPT codes 97151 and 97152 for some commercial members, depending on individual claim history.
