Fill out insurance authorization forms
with AI.
Insurance authorization forms are documents required by insurers before they approve coverage, process claims, or authorize specific medical treatments and services. These forms serve as the formal bridge between patients, healthcare providers, and insurance companies — ensuring that care is medically necessary, properly documented, and eligible for reimbursement. Whether it's a critical illness claim packet or a prior authorization request for specialized therapy, getting these forms right the first time can mean the difference between prompt payment and costly delays.

About insurance authorization forms
The people who typically need these forms span a wide range: patients filing claims after a serious diagnosis, healthcare providers seeking approval for treatments like Applied Behavior Analysis (ABA) therapy, and administrative staff managing insurance workflows on behalf of their clients. For example, a provider submitting a BCBSIL ABA authorization request must document everything from diagnostic details to weekly therapy schedules, while a patient filing a critical illness claim through CAIC/Aflac must coordinate physician statements, HIPAA releases, and payment preferences — all in one submission.
These forms are often multi-page, detail-heavy, and easy to get wrong under time pressure. Tools like Instafill.ai use AI to fill these forms accurately in under 30 seconds, handling the data securely so providers and patients can focus on care rather than paperwork.

How to Choose the Right Form
Are You Filing a Claim or Requesting Prior Authorization?
These two forms serve very different purposes — choosing the wrong one can delay your benefits or treatment approval. Here's how to quickly identify which form you need:
Filing a Critical Illness Insurance Claim
If you or a covered family member has been diagnosed with a qualifying critical illness (such as cancer, heart attack, or stroke) and you need to submit a claim for benefits, you want the:
- Continental American Insurance Company (CAIC) / Aflac Group Critical Illness Claim Form — Use this if you hold a CAIC or Aflac Group critical illness policy. This packet covers everything in one place:
- Policyholder and patient information
- Diagnosis and qualifying event details
- Attending Physician's Statement (required for medical substantiation)
- HIPAA Authorization for records release
- Optional direct deposit (EFT) setup for faster payment
Requesting Authorization for ABA Therapy Services
If you are a healthcare provider seeking approval for Applied Behavior Analysis (ABA) therapy for a patient with an ASD diagnosis covered under a BCBSIL plan, you need the:
- ABA Initial Assessment Request and Clinical Service Request Form (BCBSIL) — This is a provider-submitted prior authorization form, *not* a claim form. Use it to request approval for:
- Initial ABA assessments
- Ongoing direct treatment or group therapy
- Family training services
This form requires detailed clinical documentation, including treatment history, behavioral assessments, and weekly therapy schedules.

Tips for insurance authorization forms
Before starting any insurance authorization or claim form, collect all required supporting materials — such as diagnosis records, physician statements, and policy numbers. Having everything on hand prevents you from abandoning a partially completed form and reduces the chance of submission errors caused by missing information.
Leaving fields blank — even those marked optional — can trigger manual review or requests for additional information, slowing down your claim or authorization. For forms like the CAIC Critical Illness packet, filling out the Electronic Funds Transaction section upfront means faster payment if your claim is approved.
Authorization forms like the BCBSIL ABA request require specific diagnostic codes (e.g., ASD diagnosis) and verified provider credentials. A single incorrect or outdated code can result in denial, so confirm these details directly with the treating provider before submitting.
AI-powered tools like Instafill.ai can complete complex insurance authorization forms — including multi-page documents like the BCBSIL ABA request — in under 30 seconds with high accuracy. Your data stays secure throughout the process, making it a practical time-saver whether you're a provider handling multiple authorizations or a patient filing a single claim.
Many insurance claim packets, including the CAIC/Aflac Critical Illness form, include a HIPAA Authorization that permits the insurer to access your medical records. Read this section carefully so you understand what information will be shared, with whom, and for how long — it's a legally significant part of the packet.
Always save a complete copy of your filled-out form and any attachments before submitting. If a claim is delayed or denied, having your original submission on hand makes it much easier to identify discrepancies, respond to follow-up requests, or file an appeal.
Name spellings, dates of birth, member ID numbers, and group policy numbers must match exactly what the insurer has on file. Even minor discrepancies can cause a claim to be flagged or rejected, requiring time-consuming corrections and resubmission.
For behavioral health authorizations like ABA therapy requests, vague or incomplete treatment plans are a leading cause of denial. Include specific behavioral goals, measurable outcomes, weekly hour breakdowns, and fade/discharge criteria to give reviewers everything they need to approve services without follow-up.
Frequently Asked Questions
Insurance authorization forms are used to request approval for medical services, file claims for covered benefits, or authorize insurers to access medical records needed to process a claim. They serve as the official documentation bridge between policyholders, healthcare providers, and insurance companies to ensure that treatments and reimbursements are properly reviewed and approved.
Depending on the form, either the policyholder/patient or a licensed healthcare provider may be responsible for completing it. For example, a Critical Illness claim form is typically completed by the policyholder and their attending physician, while an ABA therapy authorization request must be submitted by a qualified provider on behalf of the patient.
A prior authorization form is submitted before services are rendered to obtain insurer approval, while a claim form is submitted after services have been provided to request reimbursement or benefit payment. Both types may require supporting clinical documentation, but prior authorization forms focus on medical necessity, whereas claim forms focus on documenting the event or treatment that occurred.
Use the Continental American Insurance Company (CAIC) / Aflac Group Critical Illness Claim Form if you are filing a claim for a qualifying critical illness diagnosis under a CAIC or Aflac Group policy. Use the BCBSIL ABA Initial Assessment and Clinical Service Request Form if you are a healthcare provider seeking authorization for Applied Behavior Analysis therapy for a Blue Cross Blue Shield of Illinois member diagnosed with ASD.
Most insurance authorization forms require supporting clinical documentation such as physician statements, diagnosis codes, medical records, and treatment plans. For critical illness claims, an Attending Physician's Statement and relevant diagnostic test results are commonly required, while ABA authorization requests typically need behavioral assessments, treatment plans, and provider credentials.

Using an AI-assisted service like Instafill.ai, the same forms can be filled out in under 30 seconds, with data accurately extracted and placed into the correct fields.
Submission methods vary by insurer and form type. Critical illness claim forms for CAIC/Aflac are typically mailed or submitted to the address or contact specified in the policy documents, while BCBSIL ABA authorization requests are submitted directly by the provider to Blue Cross and Blue Shield of Illinois through their designated provider portal or fax line. Always verify the current submission instructions with the insurer before sending.
Incomplete forms are a leading cause of processing delays, requests for additional information, or outright denial of claims and authorizations. Insurers typically require all mandatory fields to be filled in and all supporting documentation to be attached before they will begin reviewing a submission.
Many insurance claim packets, such as the CAIC/Aflac Critical Illness Claim Form, include a HIPAA Authorization as a required component. This authorization gives the insurer legal permission to obtain medical records and information from healthcare providers necessary to evaluate and process the claim.
Yes — the CAIC/Aflac Critical Illness Claim Form includes an optional Electronic Funds Transaction (EFT) authorization section that allows claimants to set up direct deposit for their benefit payments. Completing this section can speed up payment delivery compared to receiving a paper check.
Yes — the BCBSIL ABA Initial Assessment and Clinical Service Request Form requires detailed provider credential information, and submissions must come from qualified healthcare professionals authorized to diagnose and treat Autism Spectrum Disorder (ASD). Providers should ensure their credentials and NPI information are current and accurately reflected on the form to avoid authorization delays.
