There can be confusion regarding billing in healthcare for both the provider and the patient. A significant part of this process is the assignment of benefit (AOB) form, which determines how an insurer will pay a provider and how soon they will get paid for the services rendered.
Many healthcare organisations include the use of an AOB form at the time of registration. The AOB form provides the insurance company with the ability to send the payment directly to the provider rather than to the individual patient.

AOB Medical Abbreviation Explained
The acronym AOB in the medical field stands for assignment of benefits or authorization to send payment from you or your insurer directly to your provider.
In healthcare, this means that a patient has authorized the insurer to pay their health care provider directly for the services received.
AOB is most often associated with the following:
- Insurance verification
- Benefit Authorization
- Claims processing
- Medical assignments
- Revenue cycle
What Is Assignment of Benefits (AOB)?
Wondering what the assignment of benefits is? It’s very straightforward!
AOB is an agreement between a patient and a medical treatment facility stating that the facility can access payment through the patient’s insurance company.
Without an assignment of benefits, payments go directly to the patient first; therefore, payment to the facility will be delayed. As a result, the facility must do additional billing work because reimbursement takes longer.
By signing an assignment of benefits, the medical treatment facility is able to:
- Receive payments much faster.
- Process claims much easier.
- Decrease the number of errors in their billing.
- Simplify patient collections.
How AOB Works in Medical Billing
Demystifying an Assignment of Benefits AOB in Medical Billing is critical to the success of all health care organizations. The steps to completing this process are as follows:
Step One – The Patient Signs the Assignment of Benefits Form
The patient will need to sign a form assigning their benefit to the health care provider prior to receiving services (registration or check-in).
The assignment provides the provider with permission to:
- Submit Insurance Claims (Bill)
- Receive Direct Payment
- Share Any Required Medical Information with the Insurance Company (payer)
Step Two – Verifying Insurance Benefits
The billing department determines whether the patient has active insurance coverage and verifies several areas of eligibility.
Insurance Verification Includes:
- Eligibility
- Active Coverage
- Co-Pays
- Deductibles
- Prior Authorization Requirements
Verifying the patient’s insurance coverage prior to providing services will have an impact on preventing claim denials.
3rd Step – Providing Medical Services
The healthcare provider provides services, and then documents these services provided.
When documenting services performed, accurate documentation supports coding and claims submissions.
4th Step – Submitting Claims
The medical billing department electronically submits the claim to the insurance carrier.The signed assignment of benefits (AOB) provides support for the claim and is necessary for processing the payment to the healthcare provider.
5th step – Receiving Payments from the Insurance Carrier
Once the insurance carrier processes the claim, they send the reimbursement to the healthcare provider. This practice of sending the payment to the healthcare provider immediately will decrease the time between submitting the claim and receiving the reimbursement, thus improving revenue cycle performance.
When Should You Sign an Assignment of Benefits Form?
Patients should typically complete a form called an assignment of benefits (AOB) before receiving medical care. An AOB form is typically necessary in the following situations:
Routine Doctor Visits
Most medical practices require patients to complete an AOB prior to their visit so that they may expedite the processing of claims to payers.
Long-Term Care
Generally speaking, patients who are receiving long-term medical care for example, physical therapy, behavioral health, chiropractic services, dialysis, rehabilitation services usually complete one AOB for the duration of their care.
Insurance Billing
AOB forms are very important for ensuring that an insurance company will reimburse providers directly instead of sending reimbursement to a patient.
Speed of Claims Processing
Completing an AOB allows providers to streamline their processes related to the billing and payment of claims therefore avoiding delays in payment and any confusion about payments or billing to a patient.
