Healthcare practices can check on the coverage provided by the health plans in addition to the deductibles, co-insurance, and copayments. The entire process can be carried out with the patient eligibility process and VOB in medical billing.

Eligibility verification in healthcare RCM encourages collecting coverage status and minimizes the risk of claim denials. Furthermore, verification of benefits and patient eligibility enables providers to get payments in advance, avoiding delays in cash realization.

VOB in Medical Billing

VOB, or verification of benefits, is an essential step in the insurance claims and medical billing process. The step involves verifying a patient’s health insurance coverage and the benefits they receive for specific treatment or services.
The process involves checking with a patient’s insurance provider to determine the following:

Eligibility Verification
– verify whether or not a patient’s insurance plan is active or whether it covers the medical treatment/services they are seeking.
Coverage Verification – here, providers determine the extent of coverage for specific medical services; such coverage may or may not include:

  • Deductibles
  • Co-pays
  • Co-insurance

Pre-authorization – is also essential to ensure that pre-authorization is not needed for a particular planned medical procedure.
Let’s explore VOB in medical billing in depth:

The VOB Process in Medical Billing

The process of VOB in medical billing comprises the following steps, including:

Patient Information Collection

Healthcare providers collect patient information, which includes their insurance details, before scheduling the medical treatment/service.

Getting in touch with Insurance Provider

Ideally, a healthcare provider’s administrative and billing staff contacts the patient’s insurance provider to verify their benefits. The process might involve using an online portal or calling the insurance company.

Verifying Specifics

During the verification process, the following information is verified:

  • A patient’s policy status to see whether it is active or inactive
  • Checking patient’s coverage for a specific medical service
  • Co-pays, deductibles, and co-insurance amounts
  • The requirements of pre-authorization – if any


The results of the entire verification process are then documented in a patient’s medical record, with the estimated patient responsibility recorded.

Patient Communication

Patient communication is yet another important step of the VOB in medical billing. Here, patients are informed about their financial responsibility and pre-authorization requirements, if any. Further, the patient may also pay applicable co-pays or any upfront deductibles.

Importance of VOB in Medical Billing

VOB has an essential role in medical billing, and that is for several reasons, including:

– by verifying patient insurance benefits, medical providers can estimate a patient’s financial responsibility. That alone helps minimize billing errors and also avoid surprise-unexpected costs for patients.
Transparency in Costs – Patients can make informed decisions about their medical care and treatment by ensuring cost transparency. Especially when patient know and understand their financial responsibility upfront. Here, VOB in medical billing helps provide cost transparency.
Claim Rejections – If left unverified, insurance information can lead to claim rejections, resulting in reimbursement delays. VOB can help reduce claim denials and ensure fast payments.
Compliance – VOB in the medical billing process ensures provider compliance with the insurance guidelines and policies. Ensuring healthcare providers’ compliance can minimize legal and compliance risks.

Timelines of VOB in Medical Billing

Healthcare providers must check a patient’s eligibility 48 hours before their appointment. If this is not possible, it must be done in real-time before the treatment – during patient check-in. On-time eligibility checks help in reducing the number of claim denials.
Moreover, electronic eligibility verification or checking is available in most EHRs. Following the timelines of eligibility verification, your practice can reduce denials. Additionally, your practice can boost revenue realization through timely verification of patient coverage before delivering treatment.

Challenges in Verification of Benefits in Medical Billing

While determining how to verify insurance benefits and coverage, healthcare providers may encounter many challenges, including the following:

Long Process

Verifying and learning how to verify insurance benefits and eligibility takes more time if the process is done manually via email or phone. The process can be specifically challenging for providers who need to check insurance information immediately to minimize delays in patient care.

Restricted Access to Insurance Information

Care providers may have limited access to patient’s coverage and benefits information, making it more difficult for healthcare providers to verify insurance eligibility.

Complexity of Insurance Plans

Some health insurance plans can be complex and even challenging to understand. This further complicates healthcare providers’ ability to assess what services are covered and how much a patient would have to pay.

Erroneous Information

The insurance benefits and eligibility data can be obsolete or faulty, which in turn causes confusion and billing concerns.

Changes in Insurance Coverage

Insurance coverage may vary from instance to instance and patient to patient. Consequently, healthcare providers might sometimes be unaware of such differences and changes. Such instances result in patients receiving services that are no longer covered by their insurance plans. It results in claim denials, which lead to patient discontent.

Insurance Fraud

Instances of fraud are also one of the challenges for VOB in medical billing. Some patients purposefully offer healthcare professionals outdated or fraudulent insurance information, resulting in potential fraud and claim denials.

Electronic Remittance Advice and VOB in Medical Billing

ERA is a vital element in the post-service phase of medical billing. It provides healthcare providers with detailed and standardized information about the adjudication of a healthcare claim. When linked to the Verification of Benefits process, ERA helps streamline the financial aspects of healthcare services. Before a medical procedure, VOB involves checking and confirming a patient’s insurance coverage and benefits. Once the service is provided and a claim is submitted, ERA electronically delivers comprehensive information on how the claim was processed. This includes details such as:

  • Payment amounts
  • Adjustments
  • Reasons for denials

By integrating ERA into the medical billing workflow, providers can reconcile the payment received with the expected reimbursement based on the verified benefits. This synchronization helps reduce errors, enhance accuracy, and expedite reimbursement.

Explanation of Benefits or Explanation of Remittance and VOB in Medical Billing

EOR is another essential component in the medical billing process, providing a detailed breakdown of a healthcare claim’s processing. For VOBs, EOR complements the pre-service verification. Before rendering medical services, the Verification of Benefits process allows healthcare providers to understand the patient’s insurance coverage, copayments, and deductibles. After the service is provided, the subsequent EOR delivers a comprehensive statement explaining the adjudication of the claim. This includes details such as:

  • Services billed
  • Allowed amounts
  • Patient responsibilities
  • Any amounts paid or denied by the insurance company

By linking VOB with EOR, healthcare providers can ensure that the expected coverage aligns with the actual reimbursements. This connection reduces billing discrepancies, improving transparency and facilitating patient communication regarding financial responsibilities.
ERA and EOR are integral to the post-service phase of medical billing, providing electronic documentation of claim adjudication and explanations of benefits. When linked to the pre-service verification of benefits process, these components contribute to an accurate financial workflow, enhancing the overall efficiency of healthcare billing practices.

Best Practices for Verification of Benefits in Medical Billing

Incorporating best practices for insurance verification and eligibility criteria helps create positive patient experiences. It simultaneously lowers the administrative load and reduces the number of claim denials. Furthermore, it can boost patient satisfaction levels while ensuring that physicians receive adequate payments for their services.
Some of the best practices include:

  • Checking the patient’s insurance coverage before the appointment/treatment. This ensures patients qualify for coverage and that the treatments are covered by their insurance plan.
  • Requesting necessary insurance information from the patients right away. These include insurance carrier, plan type, and policy number. Such information can help during the VOB, coverage, and claims submission.
  • It is beneficial to use real-time eligibility verification tools to check a patient’s coverage, co-pays, or deductibles for which a patient may be responsible. Doing that might help physicians reduce the administrative load.

Final Word

Third-party medical billing companies can explicitly assist medical providers, hospitals, clinicians, and other healthcare facilities with VOB in medical billing. Verification of benefits helps ensure financial transparency and reduce the number of claims. Whether it is insurance, billing, services, payments, or patient care services, the VOB plays an essential role in the healthcare billing process, benefiting both healthcare providers and patients.
