Not many people think about what happens after a doctor sends a claim to the insurance company, but it\u2019s a big deal for practices trying to get paid on time. This is exactly where the assignment of benefits (AOB) gets involved. This simple agreement lets providers get paid directly from insurers, so they don’t have to deal with each patient individually.<\/span><\/p>\n

For practices that use medical billing services<\/span>, this small detail makes a big difference in keeping the money coming in and the administrative team sane. Keep reading as we break down how the assignment of benefits (AOB) works and why it is absolutely necessary nowadays for medical practices.<\/span>\u00a0<\/span><\/p>\n

Understanding How Assignment of Benefits Works<\/span><\/b>\u00a0<\/span><\/h2>\n

Let\u2019s first understand the \u2018How\u2019 behind the AOB. Whenever a patient needs medical services, they generally have their health insurance coverage. This coverage helps them pay the cost of their healthcare.<\/span>\u00a0<\/span><\/p>\n

In general, or everyday scenarios, the patient has to pay the deductible or copayment, which is basically a portion of their full bill; their insurance company pays the remaining portion.\u00a0<\/span>\u00a0<\/span><\/p>\n

But some situations are different. Sometimes, the patient assigns their benefits to the healthcare provider; when this happens, the provider can bill the insurer directly for the healthcare services.<\/span>\u00a0<\/span><\/p>\n

In layman’s terms, the <\/span>Assignment of Benefits (AOB)<\/strong> is nothing but a legal agreement between the healthcare provider and the patient. When a patient signs this agreement, they are giving full authority to the healthcare provider to receive payment from the insurance company directly.\u00a0<\/span>\u00a0<\/span><\/p>\n

This ensures two things:<\/span>\u00a0<\/span><\/p>\n

    \n
  1. Eases out-of-pocket pressure for the patient<\/span>\u00a0<\/span><\/li>\n
  2. Revenue protection for the healthcare provider<\/span><\/span><\/li>\n<\/ol>\n


    \nThe End-To-End Process of Assignment of Benefits<\/span><\/b>\u00a0<\/span><\/h2>\n

    The payment journey for healthcare providers becomes simple and straightforward as soon as the patient signs an AOB. Let’s show you what this process looks like from start to finish.\u00a0<\/span>\u00a0<\/span><\/p>\n

    Step 1: Patient Authorization<\/span><\/b>\u00a0<\/span><\/h3>\n

    So, at the time of the patient\u2019s check-in or registration, they are always asked to complete the intake form. This is where the AOB form makes its first appearance. Once the patient signs it, they permit the provider to receive the bill payment from the insurance company directly. A lot of <\/span>medical billing companies<\/a> tend to include this step in their onboarding protocols to simply avoid delays in reimbursements later on.\u00a0<\/span>\u00a0<\/span><\/p>\n

    Step 2: Claim Submission by the Provider<\/span><\/b>\u00a0<\/span><\/h3>\n

    After the patient has received care from the provider and has been discharged, the practice or their medical billing partner goes ahead and submits a claim to the insurance company of the patient. Now, since the patient\u2019s AOB is already on file, the submitted claim has clear instructions for the payment to go straight to the provider, not to the patient. Many practices love to speed this up, so you\u2019ll notice that their whole process is fully automated.<\/span>\u00a0<\/span><\/p>\n

    Step 3: <\/span><\/b>Insurance Review and Payout<\/span><\/b>\u00a0<\/span><\/h3>\n

    Once the insurer receives the submitted claim, they review it, check it against the insurance plan of the patient, and finally process it for further payment. If everything checks out and is good to go, the insurance company sends the reimbursement to the healthcare provider directly. You see, this direct payment is the main factor of having AOB in place. It basically removes the need for providers to chase payments from patients.\u00a0<\/span>\u00a0<\/span><\/p>\n

    Step 4: Explanation of Benefits (EOB) Sent To Patient<\/span><\/b>\u00a0<\/span><\/h3>\n

    So, the final step is the <\/span>EOB in medical billing<\/span><\/a>. Even though the provider has received the funds, the patient still gets an Explanation of Benefits from their insurance company. This document basically tells what was covered in terms of insurance, how much was paid, and whether the patient still owes anything. Keep in mind that while AOB permits direct payment, patients may still be liable for stuff like deductibles, copays, or non-covered services.<\/span>\u00a0<\/span><\/p>\n

    What Should Be Included in an AOB?<\/span><\/b>\u00a0<\/span><\/h2>\n

    To make sure that the AOB is legally compliant and valid, the form should have the following key components:<\/span>\u00a0<\/span><\/p>\n
