The American Medical Association\u2019s (<a href=\"https:\/\/www.ama-assn.org\/press-center\/ama-press-releases\/ama-survey-indicates-prior-authorization-wreaks-havoc-patient-care\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">AMA\u2019s) 2024 prior authorization physician survey<\/a>, involving 1,000 practicing physicians, showed that more than nine in ten physicians believe that obtaining prior authorization delays access to necessary patient care.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Additionally, more than three-fourths of physicians claim authorization problems with health insurers cause patients to abandon treatment.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Administrative Burden<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In terms of ABA specifically, these authorization-related therapy abandonments showcase a much more severe concern. Children with autism spectrum disorder may lose valuable intervention time during critical developmental periods.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to the same AMA survey, physicians and their staff complete an average of 43 prior authorization requests per physician each week. What does this mean? A serious administrative burden across practices.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The ABA pre-authorization process is often more complex compared to other medical specialties because it requires both an initial authorization and periodic reauthorizations throughout the treatment period.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Each ABA authorization renewal window requires:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Updated clinical data<\/li>\n\n\n\n<li>Renewed medical necessity justification<\/li>\n\n\n\n<li>Progress documentation<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Compliance Complexity<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">ABA pre-authorization also carries significant compliance implications. The Department of Human Health Services\u2019 Office of Inspector General (<a href=\"https:\/\/oig.hhs.gov\/documents\/audit\/10497\/A-06-23-01002.pdf\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">HHS OIG) Medicaid audit<\/a> findings indicate that ABA services require intensive post-payment review.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Recoupments frequently occur because of:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Hour-limit violations\u00a0<\/li>\n\n\n\n<li>Authorization gaps<\/li>\n\n\n\n<li>Documentation deficiencies<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, pre-authorization serves as the first compliance checkpoint in ABA clinics.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>ABA Pre-Authorization Process<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The ABA pre-authorization process closely aligns with the clinical workflow of ABA service delivery. Each step generates documentation that supports the next stage of the process; therefore, a breakdown at any point can delay authorization for subsequent services.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The following is a comprehensive breakdown of the ABA pre-authorization process.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Step 1: Diagnosis and Insurance Coverage Confirmation<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Before a patient undergoes an initial behavior identification assessment, the billing team should confirm two things:&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The patient must have a diagnosis of autism spectrum disorder or any other developmental delay based on DSM-5-TR criteria. Secondly, the patient\u2019s insurance plan must include coverage for ABA services.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Note that patients may not always have insurance coverage for ABA services. In some cases, insurance plans provide coverage for certain diagnosis codes, whereas others might not cover them at all.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Step 2: Behavior Identification Assessment (97151) Completion<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The adaptive or maladaptive behavior assessment (represented with <a href=\"https:\/\/www.aapc.com\/codes\/cpt-codes\/97151?srsltid=AfmBOopEb22MlH5d2B1j_nqEljJQn2LisUw1aTzBRLSyRO5R0IrIm0oH\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">CPT code 97151<\/a>) is crucial for any ABA authorization request. It is used to develop the patient\u2019s Plan of Care (POC).\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Most payers require a comprehensive diagnostic evaluation or assessment to support ABA authorization requests. This evaluation should be completed and signed by a qualified healthcare professional within the payer&#8217;s required lookback period, which is often 12 months.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Additionally, credentialing should be done according to the payer\u2019s requirements, since many times, insurers credential BCBAs independently.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Step 3: Delivery Model Determination and Correct Hours Request<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">ABA services are usually authorized based on the delivery models or treatment intensity levels. In cases where expected therapy sessions are more frequent than the model\u2019s standard limits, the ABA pre-authorization request must be supported by additional medical necessity documentation.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Step 4: Authorization Request Submission with Complete Documentation<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">An ABA prior authorization request for an insurer must include, at a minimum:<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">1. <strong>Current Diagnosis Documentation<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">A signed autism spectrum disorder diagnosis from a:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Pediatrician<\/li>\n\n\n\n<li>Psychologist<\/li>\n\n\n\n<li>Psychiatrist<\/li>\n\n\n\n<li>Other qualified evaluator<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The diagnosis should fall within the insurer&#8217;s required lookback period, which is commonly 12 months but may vary by payer.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>2. Plan of Care<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The treatment plan should be signed by the supervising BCBA and include the following:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Specific CPT codes to be delivered\u00a0<\/li>\n\n\n\n<li>Treatment goals<\/li>\n\n\n\n<li>Weekly hours<\/li>\n\n\n\n<li>Anticipated duration<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">3. <strong>Medical Necessity Statement<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">ABA pre-authorization requires a detailed medical necessity narrative. It should explain the requested service hours and delivery model based on the patient&#8217;s assessed needs.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">4. <strong>Behavior Identification Assessment Report<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">As mentioned before, a complete assessment (CPT code 97151) report is mandatory for ABA pre-authorization. Ideally, it should include the baseline data, target behaviors, and clinical rationale for the hours of therapy requested in the application.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">5. <strong>BCBA Credentials<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The latest BCBA certification and state licensure that an insurer may require.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Step 5: Authorization Tracking and Setting a Reauthorization Calendar<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Once a request has been submitted, it should be tracked daily. Many commercial insurers issue authorization determinations within several business days, although response times vary by payer.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, if your ABA pre-authorization request is urgent, it may fall under an expedited review (which is typically 24-72 hours).&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Once approved, the authorization should specify:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Approved CPT codes<\/li>\n\n\n\n<li>Weekly hour limits per code<\/li>\n\n\n\n<li>Authorization period (commonly 3, 6, or 12 months)<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">As soon as an authorization period is set, the billing teams should calendar the reauthorization deadline. The reauthorization process should typically begin 30 to 60 days before the current authorization expires.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the billing team submits the renewal request after this period (even by one day), it may result in a gap period.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">During this gap period, services may continue, but they may not be covered by an active authorization. Therefore, every claim submitted during that period is at a higher risk of denial.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Common Reasons for<\/strong><strong> ABA Pre-authorization<\/strong><strong> Delays &amp; Denials<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Delays and denials are common prior authorization challenges for ABA providers, and many can be prevented or successfully appealed. It depends on how well the billing team understands the requirements and the ABA pre-authorization itself. The following table covers the most common authorization challenges for ABA practices:<\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table><thead><tr><th class=\"has-text-align-center\" data-align=\"center\"><strong>Denial \/ Delay Reason<\/strong><\/th><th class=\"has-text-align-center\" data-align=\"center\"><strong>What It Means<\/strong><\/th><th class=\"has-text-align-center\" data-align=\"center\"><strong>How to Address It<\/strong><\/th><\/tr><\/thead><tbody><tr><td class=\"has-text-align-center\" data-align=\"center\"><em>Insufficient proof of medical necessity&nbsp;<\/em><\/td><td class=\"has-text-align-center\" data-align=\"center\">The treatment plan does not justify the requested service.
