Prior Authorization in Healthcare and How it Works

Nearly all US healthcare providers have experienced the sinking feeling of encountering a roadblock between themselves and the best course of treatment for their patient. This roadblock, the prior authorization process, often feels like an intricate maze of paperwork and waiting. 

A recent American Medical Association (AMA) survey revealed that a whopping 94% of physicians experience delays in patient care due to prior authorization. This translates to frustration for both you and your patients, hindering the efficiency and quality of care delivery.

Understanding the prior authorization process is crucial for navigating the complexities of US healthcare. This multi-step process requires securing approval from a patient’s health plan before administering specific services or medications. While intended to manage costs, prior authorization can create significant administrative burdens for providers, diverting valuable time and resources from direct patient care.

What is Prior Authorization in healthcare?


Prior authorization in healthcare, often referred to by various terms like precertification, predetermination, or pre-approval, is a multi-step process mandated by many healthcare insurance plans in the US. It requires healthcare providers to obtain written approval from a patient’s insurance company before administering specific services or medications. 

While the concept might seem straightforward, navigating the prior authorization maze can be a time-consuming and complex ordeal for both providers and patients.

Why does Prior Authorization in Healthcare exsits?

The rationale behind prior authorization is multifaceted. Insurance companies utilize it as a cost-containment measure, aiming to achieve several key objectives:

  • Medical Necessity: Prior authorization ensures the prescribed service or medication is truly necessary for the patient’s specific condition. This helps prevent unnecessary healthcare spending on treatments that might not be clinically beneficial.
  • Cost-Effectiveness: Insurance companies use prior authorization to evaluate if there are equally effective yet less expensive alternatives available. This can involve encouraging the use of generic medications or exploring less invasive procedures before resorting to more costly options.
  • Appropriate Utilization: Prior authorization helps ensure services and medications are being used according to established guidelines and best practices. This minimizes the risk of misuse or overuse of certain treatments.

The Importance of Prior Authorization in Healthcare for Patients and Providers

While prior authorization might seem like an administrative burden, it does hold some benefits for both patients and providers:

Importance of Prior Authorization

For Patients:

  • Reduced Out-of-Pocket Costs: By securing prior authorization beforehand, you can ensure the chosen treatment is covered by the patient’s plan. This minimizes the risk of patients facing unexpected out-of-pocket expenses for services or medications they were unaware wouldn’t be covered.


  • Quality of Care: Prior authorization can, in some cases, act as a safeguard against unnecessary or potentially harmful treatments. By requiring justification for certain procedures, it encourages evidence-based medicine and promotes appropriate care.

For Providers:


  • Improved Efficiency: A streamlined prior authorization process can help providers obtain timely approvals for necessary treatments, minimizing delays in patient care.


  • Reduced Liability: By following the prior authorization process, providers can ensure they are adhering to the terms and conditions of the patient’s insurance plan, potentially reducing the risk of denials or liability issues.

Challenges of Prior Authorization


However, the current state of prior authorization can often lead to significant challenges:

  • Administrative Burden: The complex and often lengthy prior authorization process can divert valuable time and resources away from direct patient care. Providers and their staff may spend hours gathering and submitting documentation, leading to frustration and inefficiency.


  • Delays in Care: The time it takes to secure approval through prior authorization can sometimes delay the initiation of necessary treatment. This can be particularly detrimental in cases where timely intervention is crucial for optimal patient outcomes.


  • Lack of Transparency: The criteria used by insurance companies to evaluate prior authorization requests can sometimes be unclear or inconsistent. This lack of transparency can make it difficult for providers to predict approval outcomes and can lead to frustration.


Why Do Health Insurers Require Prior Authorization?


The prior authorization process, while often causing frustration for both providers and patients, serves several key purposes for health insurers. Here’s a breakdown of the primary reason’s health insurers utilize prior authorization:

prior authorization

  1. Ensuring Medical Necessity: At the heart of prior authorization lies the concept of medical necessity. Insurance companies want to ensure the service or medication being requested is truly essential for the patient’s specific condition, based on established medical guidelines and evidence-based practices. They aim to prevent unnecessary healthcare spending on treatments lacking a proven benefit for the patient’s diagnosis.


Example: A patient with a mild backache might be prescribed a powerful pain medication. Prior authorization allows the insurer to assess if less invasive measures like physical therapy or over-the-counter pain medication would be a more appropriate first-line treatment before approving the stronger medication.


  1. Cost Control and Financial Efficiency: Healthcare costs continue to rise, and prior authorization acts as a tool for insurers to manage these costs. By evaluating the necessity and cost-effectiveness of proposed treatments, they can potentially steer patients towards more affordable options when equally effective alternatives exist.


Example: A brand-new, high-cost medication might be prescribed for a particular condition. Prior authorization allows the insurer to explore if a generic medication with a proven track record could achieve the same results at a lower cost for the plan.


  1. Preventing Duplication of Services: With patients potentially seeing multiple healthcare providers, prior authorization helps prevent unnecessary duplication of services.


Example: A patient might be referred to a specialist for a particular condition. Prior authorization allows the insurer to verify if similar tests or procedures haven’t already been performed by another provider within a reasonable timeframe, avoiding unnecessary repetition of services.


  1. Monitoring Ongoing Treatment Effectiveness: In some cases, prior authorization can be used to monitor the effectiveness of ongoing treatment plans. This is particularly relevant for chronic conditions or treatments requiring long-term use of medications.


Example: A patient with a chronic illness might be on a long-term course of medication. Prior authorization for refills can act as a checkpoint for the insurer to assess if the medication continues to be necessary and effective, potentially prompting a review of the treatment plan if needed.


How Does the Prior Authorization Process Work?


Now that we understand the rationale behind prior authorization, let’s delve into the nitty-gritty of the process itself. Buckle up, because navigating this maze can involve several steps and require clear communication between both healthcare providers and insurance companies. Here’s a breakdown of the typical workflow:


  1. Initiating the Process:

The prior authorization process usually starts at the provider’s office. Once a treatment plan is determined and requires prior authorization, the provider’s staff will initiate contact with the patient’s insurance company. This might involve:


  • Electronically submitting a request: Many insurance companies have online portals where providers can submit prior authorization requests electronically.


  • Faxing or mailing a form: In some cases, the insurer might require submitting a paper form outlining the treatment details and justification for medical necessity.


  1. Completing the Paperwork:

The specific information required for prior authorization requests can vary depending on the insurance company and the service or medication being requested.

However, some common elements might include:


  • Patient demographics: Name, date of birth, insurance ID number


  • Diagnosis: A clear and concise diagnosis code for the patient’s condition


  • Treatment plan: Detailed description of the proposed service or medication, including dosage and duration


  • Medical justification: A clear explanation of why the requested treatment is medically necessary and the most appropriate option for the patient’s specific case. This might involve supporting documentation like medical records, test results, or treatment guidelines.


  1. Documentation is Key:

Gathering and organizing supporting documentation is crucial for a successful prior authorization request. This documentation might include:

  • Clinical notes: Detailed notes from the provider outlining the patient’s condition, history, and rationale for the chosen treatment.


  • Test results: Relevant lab results, X-rays, or other diagnostic tests supporting the diagnosis and treatment plan.


  • Treatment guidelines: References to established medical guidelines or protocols supporting the use of the requested service or medication for the patient’s specific condition.


  1. Tracking Deadlines:

Prior authorization requests are subject to deadlines set by the insurance company. These deadlines vary depending on the insurer and the type of service or medication being requested. It’s crucial for the provider’s office to track these deadlines and ensure timely submission to avoid delays in care.


  1. Collaboration is Essential:

While the responsibility for initiating and completing the prior authorization process falls on the provider’s office, clear communication with the patient is also important. Patients should be informed about the request and any potential delays caused by the prior authorization process. Additionally, some insurance companies allow patients to check on the status of their prior authorization requests directly.

The Role of Healthcare Providers:


Healthcare providers play a pivotal role in navigating the prior authorization maze. Their responsibility lies in:


  • Identifying services requiring prior authorization: Understanding which services or medications are subject to prior authorization for specific insurance plans.


  • Completing the necessary paperwork: Accurately and comprehensively filling out prior authorization requests and gathering supporting documentation.


  • Communicating effectively with patients: Keeping patients informed about the process and potential delays caused by prior authorization.


The Role of Insurance Companies:


Insurance companies have the responsibility to:

  • Establish clear and transparent guidelines: Providing clear and readily available information on which services require prior authorization and the criteria used for evaluation.


  • Streamlining the process: Utilizing efficient electronic systems for submitting and tracking prior authorization requests.


  • Providing timely responses: Responding to prior authorization requests within established timeframes to minimize delays in care.


Common Services and Medications Requiring Prior Authorization


Prior Auth specific requirements can vary depending on the insurance plan, some services and medications are more commonly subject to prior authorization than others. Here’s a breakdown of some frequently encountered categories:

Prior Authorization services

Non-Emergency Services:

Many insurance plans require prior authorization for non-emergency services to ensure medical necessity and cost-effectiveness. Some common examples include:


  • Diagnostic Imaging: Advanced imaging tests such as Magnetic Resonance Imaging (MRI), Computed Tomography (CT) scans, and Positron Emission Tomography (PET) scans might require prior authorization, especially if non-invasive alternatives haven’t been explored first.


  • Durable Medical Equipment (DME): Items like wheelchairs, hospital beds, and other assistive equipment might require prior authorization to ensure they are medically necessary and appropriate for the patient’s needs.


  • Rehabilitation Services: Physical therapy, occupational therapy, and speech therapy services often require prior authorization, particularly when ongoing or long-term treatment plans are recommended.


  • Home Health Services: In-home care provided by nurses or other healthcare professionals might require prior authorization, especially if the services are deemed non-essential or custodial in nature.


  • Non-Emergency Surgeries: Elective surgeries for cosmetic procedures or non-critical conditions often require prior authorization to ensure they are medically necessary and not purely for aesthetic purposes.



Certain medications, particularly those deemed high-cost, brand-new, or with potential for misuse, are more likely to be subject to prior authorization. Here are some common examples:

  • Specialty Medications: Drugs used to treat complex or chronic conditions, often carrying a high price tag, might require justification for their use before being approved.


  • Brand-Name Medications: While generic alternatives might be available, prior authorization can act as a gatekeeper to ensure the brand-name medication is truly necessary and cost-effective in the patient’s specific case.


  • Controlled Substances: Medications with a high risk for abuse or dependence, such as opioids or certain pain medications, often require prior authorization to minimize misuse.


Medications with Potentially Severe Side Effects:


Certain medications, while effective for some conditions, can have serious or life-threatening side effects. Prior authorization helps ensure these medications are used only when absolutely necessary and the potential benefits outweigh the risks. Here are some examples:


  • Chemotherapy drugs: Used to treat cancer, these medications can have severe side effects like nausea, hair loss, and damage to healthy cells.


  • Immunosuppressant drugs: These medications suppress the immune system to prevent organ rejection after transplants, but can increase the risk of infections.


Medications with High Misuse or Addiction Potential:


Prior authorization helps regulate access to medications with a high potential for misuse or addiction. Here are some examples:


  • Opioid pain medications: These powerful pain medications can be highly addictive and prior authorization helps ensure they are prescribed appropriately and only for short-term management of severe pain.


  • Stimulants: Used to treat conditions like ADHD, these medications can have side effects like anxiety and insomnia. Prior authorization helps ensure they are prescribed for legitimate medical reasons and not misused.


Cosmetic-Use Drugs:


Many insurance companies exclude coverage for cosmetic procedures and medications used solely for aesthetic purposes. Prior authorization helps ensure these medications are not covered by insurance plans when used for non-medical reasons.


Expensive Drugs with Cheaper Alternatives:


Prior authorization can act as a cost-containment measure by encouraging the use of generic medications or treatments with lower price points. Here are some examples:


  • Brand-name medications: When a generic alternative with the same effectiveness exists, prior authorization can help steer patients towards the more affordable option.


  • New and emerging medications: High-cost, newly developed medications might require prior authorization to assess their effectiveness and ensure they offer a significant advantage over existing treatments before being routinely covered by insurance.


It’s important to remember that these are just some common examples. The specific medications requiring prior authorization will vary depending on the insurance plan and its guidelines. 


Challenges and Controversies in the Prior Authorization Process


Treatment Delays and Patient Impact:


One of the most significant concerns surrounding prior authorization is the potential for treatment delays.

Administrative Burdens on Healthcare Providers:


The prior authorization process can place a significant administrative burden on healthcare providers and their staff. The time and resources spent gathering documentation, completing forms, and following up with insurance companies can detract from the time providers spend directly caring for patients.

Here are some ways the administrative burden affects providers:


  • Reduced Patient Care Time: The time spent navigating prior authorization can take away from providers’ time spent seeing patients and delivering care.


  • Increased Staff Burnout: The additional workload associated with prior authorization can contribute to staff burnout and decreased morale.


  • Higher Costs for Practices: The time and resources dedicated to prior authorization can translate to increased operating costs for healthcare practices.


Controversies and Lack of Transparency:


A major controversy surrounding prior authorization is the lack of clarity and transparency in the criteria used by insurance companies to evaluate requests. This lack of transparency makes it difficult for providers to predict approval outcomes and can lead to frustration and wasted time. Additionally, some argue that the emphasis on cost-containment through prior authorization can sometimes supersede patient needs, leading to denials for essential treatments.
