What Is Prior Authorization in Medical Billing?
If you have ever wondered what is prior authorization in medical billing, you are not alone. Patients, billing staff and even new coders often get confused about this step in the insurance process. Prior authorization is a conditional approval a healthcare provider receives from the patient's insurance company for a specific treatment, test, procedure or medicine before it is administered.
If the insurance doesn't approve, the insurance company will not cover the claim and the patient may be left with a huge bill. This article will explore pre authorization in medical billing, pre certification in medical billing, referral authorization in medical billing and various types of authorization that are used in medical billing today.
What Is Prior Authorization
Medical billing prior authorization is a procedure that the healthcare provider follows when seeking approval with the insurance provider before providing a certain service to the patient. The insurance company reviews the request, and verifies whether treatment is medically necessary and is covered by the patient's plan. Once this approval is granted, the provider can proceed with billing for the service.
This process is in place because insurance companies want to keep costs under control and ensure that costly treatments are necessary. Many people ask what is prior authorization in medical billing because it has a direct impact on the time they can get their treatment and whether or not the claim will be paid. The approval typically takes the shape of a reference number which the billing team adds to the claim prior to it being sent out.
Why Prior Authorization Is Important in Medical Billing
Prior authorisation is a key part of the efficiency of a medical practice. Failure to do so by the front desk/billing staff can cause the claim to be rejected at a later date and the provider may not be paid for services rendered. That is why it's one of the first things a new biller learns about prior authorization.
There are a few reasons insurance companies require this approval:
- To confirm the treatment is medically necessary
- To control unnecessary or duplicate testing
- To check if a cheaper alternative treatment is available
- To manage the overall cost of patient care
For practices working with a high volume of claims, missing this step even once can lead to lost revenue and unhappy patients.
Types of Authorization in Medical Billing
In medical billing, there are various authorization types, and each will have a slightly different purpose. Medical billing staff can better understand which documents are required before a claim is filed by understanding the types of authorization. The most frequent ones are:
- Prior authorization, also known as approval required before a service is provided
- Pre authorization, which many payers use as their official term for the same approval
- Pre certification, which is approval required mainly for hospital admissions or inpatient stays
- Referral authorization, which is approval needed when a primary doctor sends a patient to a specialist
- Concurrent authorization, which is approval needed to continue an ongoing treatment such as an extended hospital stay
Many practices wonder what is pre authorization in medical billing compared to prior authorization, but in most cases insurers use the two terms interchangeably, and the paperwork is nearly the same. Many billing teams have a specific question about pre certification, particularly in relation to medical billing because it is applied frequently in the context of inpatient admissions and length of stay in hospitals. Billing teams need to understand which type of service goes with each, with different rules, timelines and paperwork.
What Is Referral Authorization in Medical Billing?
When a family doctor tells patients they should see a specialist, many patients wonder about what it is medical billing referring to. A primary care physician's written authorization from the insurance carrier to refer a patient to another physician, typically a specialist. If this is not approved, the visit to the specialist may not be covered by insurance.
This type of authorization is widely used in HMO plans, in which the main practitioner serves as a gatekeeper to every other care. The specialist's office might request payment up front or reschedule the appointment until the paperwork is in order if the referral is not included.
Medical Services That Usually Require Prior Authorization
While some medical services do not require approval, many medical services are almost always required to be approved. These include:
- MRI and CT scans
- Surgeries, such as outpatient surgeries,
- Specialty medications, some prescription medications
- Equipment used for extended periods, such as a wheelchair or an oxygen machine.
- Inpatient hospital admissions
- Physical therapy beyond a set number of visits
- Mental health and substance abuse treatment in some plans
Providers should always check the patient's insurance plan before scheduling any of the above to avoid delays at the front desk and subsequent billing denials.
How Prior Authorization Works in the Medical Billing Process
The process usually starts when a doctor decides a patient needs a certain test, medication, or procedure. The billing or administrative staff then submits a request to the insurance company with details about the diagnosis and treatment plan. The insurance company reviews the request, sometimes asking for more medical records, and gives a decision within a set number of days.
If approved, the provider gets an authorization number that must be included on the claim. If denied, the provider can appeal the decision or look for other covered options. This back and forth is exactly what is prior authorization in medical billing in real practice, and it remains one of the more time consuming parts of the billing cycle.
Common Prior Authorization Challenges in Medical Billing
Even experienced billing teams run into problems with authorization. Some common challenges include:
- Long wait times for insurance company decisions
- Missing or incomplete medical documentation
- Different rules for different insurance plans
- Authorization expiring before the service is completed
- Denials caused by small clerical errors
These issues can delay patient care and create extra work for billing staff. This is exactly why learning what is prior authorization in medical billing matters for every person working in a billing department, not just the senior staff.
How to Improve Your Prior Authorization Process
Here are a few tips and tricks to smooth and quicken the authorization process:
- Check insurance coverage prior to scheduling services
- Keep a checklist of services that commonly need approval
- Submit requests with complete documentation the first time
- Track authorization expiration dates closely
- Follow up regularly with the insurance company on pending requests
Practices that build a strong system around these steps usually see fewer denied claims and faster payments from insurance companies.
