Prior Authorization Best Practices: Reducing Denials and Patient Access Delays

Prior authorization continues to create challenges for patient access teams, particularly as payer requirements become more complex and documentation requirements vary across plans. For specialty and rare disease therapies, those challenges can become even more pronounced, with offices often responsible for gathering detailed clinical information while navigating different requirements across payers and plans.

Earlier this month at Informa’s Hub West 2026, SuperDial’s Vice President of Product, Entela Duka, moderated a discussion on how healthcare teams can make the prior authorization process more efficient and reduce avoidable delays in access to treatment. She was joined by Ellis Wheby, Director of Patient Services & Distribution at Tarsus Pharmaceuticals, and Melissa Polvi, Field Access Manager at Insmed. The conversation explored the operational challenges surrounding prior authorization, from documentation and staff training to specialty pharmacy coordination and the role of automation.

Across the discussion, one idea came up repeatedly: the more that can be done to make the initial submission complete and accurate, the less time teams have to spend correcting problems later.

Prior authorization is increasingly documentation-driven

For specialty and rare disease therapies, completing a prior authorization can require a detailed clinical picture. Depending on the therapy and the payer, an office may need to provide a confirmed diagnosis, genetic testing, lab values, previous treatment history, documentation of tried and failed therapies, and evidence of specialist involvement. Requirements can also vary significantly from one health plan to another, which means staff need to understand both the therapy-specific criteria and the details of the patient’s coverage.

That complexity creates a persistent source of avoidable delays: missing information. An office may have the clinical information needed to support an authorization but fail to attach a lab result, imaging report, or other supporting record. When the payer cannot readily determine that its criteria have been met, the request may be denied and require additional follow-up or an appeal.

One practical way to address this is through a prior authorization checklist. A checklist gives staff a clear reference for the information and attachments required before submission, creating a more consistent process and making it easier to identify gaps before the request reaches the payer. During the panel, the importance of this kind of upfront preparation came up repeatedly as a way to reduce rework later in the process.

Training needs to reflect how each office actually works

A consistent PA process also depends on how well the people responsible for it understand their roles. In many practices, prior authorization touches several members of the office. Front desk staff may collect insurance information, clinical teams may coordinate testing and documentation, and another employee may ultimately complete and submit the authorization. If those responsibilities are not clearly understood across the office, information can easily be missed or delayed before the PA ever reaches the payer.

Training therefore needs to account for the full office workflow rather than focusing only on the person who ultimately submits the request. If a payer requires a particular test within a certain timeframe, for example, the office needs a reliable way to make sure the test is completed, documented correctly, and available to the person handling the authorization.

Staffing changes make this even more important. Some practices have a dedicated prior authorization or biologics coordinator, while others distribute the work across several employees. Turnover can create another point of failure when knowledge about a particular therapy or payer requirement sits with only one person. Building repeatable processes and training backup staff can help practices maintain continuity when responsibilities change, while concise, therapy-specific guidance can make it easier for new staff to get up to speed.

Better specialty pharmacy coordination can reduce friction

The PA process also depends on coordination beyond the provider’s office. Specialty pharmacies can support benefits investigations, identify payer requirements, initiate or support prior authorizations, and surface recurring problems with documentation. Because they see these processes across many patients and practices, they can also provide useful visibility into patterns that might be harder for an individual office to recognize.

That visibility is particularly valuable when the same issue appears repeatedly. If a practice regularly submits a request without a required piece of documentation, for instance, that pattern can be addressed through training or process changes rather than being handled as a one-off problem each time.

At the same time, adding more organizations to the process can introduce its own coordination challenges. Different teams may have their own outreach schedules and escalation procedures, which can result in an office receiving multiple calls about the same authorization. Coordinating those efforts, defining who owns each step, and establishing clear escalation paths can reduce unnecessary outreach and make the overall process easier for provider offices to manage.

The goal is to make each handoff move the request forward rather than create another layer of administrative work.

Where automation can improve the PA process

Many of the repetitive and rules-based parts of prior authorization are well suited to automation. Technology can help flag missing information, support benefits investigations, identify relevant requirements, and prevent incomplete authorizations from moving forward. When those checks happen before submission, staff have an opportunity to fix the problem while it is still relatively simple to resolve.

That can matter because the cost of an incomplete submission is often much higher after the authorization has already been denied. Staff may need to determine why the request was rejected, gather additional documentation, contact the payer, and prepare an appeal. Building checks into the workflow can help prevent some of that downstream work by identifying common issues before the request is submitted.

The difficulty is that payer requirements are not uniform. Different plans can require different forms, tests, documentation, and processes, and even patients covered through the same employer may have different plan-specific requirements. Medical exceptions, letters of medical necessity, and step edits can introduce additional variation. Any technology used in this part of the process therefore needs to account for those differences rather than assuming that every prior authorization follows the same path.

Human judgment still matters

Automation can remove repetitive work from the process, but it does not eliminate the need for human judgment. This is particularly true in rare disease, where understanding whether a patient meets a payer’s criteria can require a broader view of the patient’s clinical history.

A prior authorization may need to reflect several conditions, previous treatments, test results, and other factors that together explain why a particular therapy is appropriate. Capturing that context requires more than simply checking whether a field has been completed. The people preparing the authorization need to understand the patient’s situation and how the available documentation supports the request.

The same principle applies after a PA is approved. Approval is an important step, but it does not guarantee that the patient immediately starts therapy. Provider offices and specialty pharmacies still need to communicate with patients about what to expect during the access process and what happens next. Automation can support those administrative workflows, while people remain responsible for the conversations and decisions that require context.

Connecting payer automation to the broader access process

Prior authorization is one part of a much larger set of interactions between healthcare organizations and payers. Teams may need to determine whether authorization is required, check the status of an existing request, confirm the appropriate submission method, identify missing documentation, or determine what action is needed after speaking with a payer.

SuperDial’s voice and multimodal AI agents automate these types of payer interactions across phone, portals, APIs, and EDI. For prior authorization workflows, SuperDial can retrieve information such as authorization requirements and status, submission methods, effective and expiration dates, missing documentation, and next steps. The information is returned as structured data that can be used by teams and their existing systems, helping reduce the amount of manual work involved in navigating payer workflows.

The broader opportunity is to connect those individual administrative tasks into a more consistent process. When information can be retrieved and organized automatically, staff can spend less time tracking down routine answers and more time handling the cases where their knowledge and judgment make the biggest difference.

Getting the first submission right

Improving prior authorization does not always mean adding another layer to the process. In many cases, it means making the existing process more reliable from the start.

Before submitting a PA, teams should understand the payer’s requirements, gather the appropriate clinical information, and confirm that all required documentation is attached. When a denial does occur, the stated denial reason should guide the response. If the payer identifies a missing lab value, for example, the appeal should directly address that issue rather than simply repeating the broader rationale for why the patient needs the medication.

The underlying principle is simple: prior authorization is part of the patient access process, not a separate administrative task that happens around it. For specialty and rare disease therapies, the quality and efficiency of that process can directly affect how quickly a patient moves from prescription to treatment.

Clearer requirements, complete documentation, coordinated handoffs, and automation that catches preventable issues earlier can all help reduce friction. The more teams can resolve upstream, the less time they need to spend revisiting the same authorization later.
