Workflow Tips to Help Manage Prior Authorization Requirements

Editor’s Note: This blog was originally published on June 26, 2023, and has been updated since. 

Prior authorization (PA) is the process by which pathology groups and clinical laboratories must obtain payer approval before performing certain medical services or procedures. At its core, prior authorization balances medical decision-making with fiscal responsibility by determining whether a proposed test or treatment will be covered. 

However, in practice, PA often creates significant laboratory billing challenges for lab organizations, other healthcare providers, and patients by adding administrative burden, delaying care, and increasing the risk of denials and revenue leakage.

Current Industry Standards and the Steps Associated with Prior Authorization

Prior authorization typically begins when a provider evaluates a patient and determines that a specific service or procedure is medically necessary. If the service is not automatically covered under the patient's insurance plan, the payer must approve it before testing or treatment can proceed.

Beyond this high-level step, the prior authorization process involves several important realities:

• Coverage for medical services and procedures varies widely among payers.
• Documentation requirements are payer-defined and often differ significantly from one insurer to another.
• You may submit requests by telephone, fax, email, or electronic data interchange (EDI).
• Initial response times commonly range from five to ten business days.
• Payers respond with an approval, denial, or a request for additional supporting information.

These complexities directly affect provider reimbursement and patient care. Laboratory testing requirements vary by payer, health plan, and state regulations, adding complexity to the prior authorization process. These requirements can create bottlenecks in laboratory revenue cycle management (RCM), and delay reimbursement, disrupt cash flow, and increase the likelihood of claim denials.

Improving Prior Authorization Workflow Efficiency

So, how can laboratories reduce these bottlenecks and gain greater control over the billing process?

The key is to reduce labor-intensive tasks and unnecessary administrative steps while implementing a structured, end-to-end workflow that integrates prior authorization into routine pathology and clinical laboratory operations.

An effective lab workflow should include:

• Clearly defined front-end and back-end process ownership.
• The ability to identify operational gaps and improvement opportunities.
• Compartmentalized tracking of prior authorization, denials, and related claim transactions.
• Standardized task workflows for repeatable lab RCM activities.

This level of process discipline enables consistent productivity measurement and creates the foundation for scalable laboratory operations and sustainable laboratory revenue cycle management performance.

Specialized Laboratory Billing Workflow Queues

Efficiency Opportunity

As concerns about the administrative burden, costs, and inefficiencies of prior authorization mount, the healthcare industry is exploring new laboratory billing approaches to reduce them.

Professional healthcare organizations like the American Medical Association (AMA) promote an automated prior authorization laboratory billing process that uses standard electronic transactions to increase uniformity across health plans and streamline workflows.

Initiatives involving electronic prior authorization systems, standardized protocols, and improved communication among all involved entities are additional ways to reduce inefficiency.

Operational Impact

Configurable laboratory billing workflow queues, such as those available in the LigoLab platform, allow testing organizations to streamline workflows effortlessly.

Users can also combine these lab workflow queues with the platform's innovative rules engine to automate certain aspects.

The queues are designed for data organization and validation, helping prevent overlooked claims and freeing resources for more complex lab RCM processes.

LigoLab’s Rules Engine

Efficiency Opportunity:

In 2021, Medicare Advantage insurers overturned more than 80 percent of their initial prior authorization denials after reconsideration with the necessary documentation.

For the 2021 plan year, 114 contracts failed data validation, including all contracts for Anthem Blue Cross Blue Shield plans.

Operational Impact:

LigoLab’s rules engine lets users configure operational settings for a laboratory billing workflow task, data-entity-driven reminders ("ticklers"/"tags"), and data validation without manual intervention.

Additionally, rules and conditions can respond to specific laboratory billing workflow triggers, automatically initiating a cascade of data updates and actions based on the selected configuration. 

This combination of conditions will reduce prior authorization denials caused by inaccurate or missing data related to payer documentation requirements.

LigoLab’s Reporting Module

Efficiency Opportunity:

In Experian Health’s State of Claims 2022 survey, 62 percent of healthcare executives said they lack sufficient data and analytics to identify issues as lab billing claims are submitted.

The same survey also reported that failure to verify provider eligibility and code inaccuracies are two of the top three reasons for denials.

Operational Impact:

LigoLab's robust reporting module retrieves real-time claim-related and analytics data.

Configurable data entity filters isolate virtually any type of data involved in processing a laboratory billing transaction.

Combining the rules engine and reporting module within lab billing workflows can help reduce the multi-million-dollar revenue losses reported by 35 percent of hospitals and health systems in fiscal year 2022.

Account-Based Transactions

Efficiency Opportunity:

Payers often change prior authorization requirements within the same fiscal year, causing delays and sometimes resulting in rejections (here’s an example of a notification and requirements from a payer).

Changes to requirements can vary and, in certain cases, can be significant, so having a central outline of all the relevant data along with any data modifications made to a claim can be the difference between potential rejections and efficient processing.

Operational Impact:

LigoLab’s account-based transactions link all claim-related data and transactions within a single account, represented via data rows. 

User-friendly, intuitive navigation provides open yet secure access to all claim data within a single user interface, significantly improving laboratory workflow management efficiency.

Retrieving the relevant data needed to meet payer documentation requirements for appeal or prior authorization packages becomes a standardized laboratory billing process.

Overall, transparency, accuracy, and secure access to claim-related data reduce prior authorization denials and increase cash flow.

The Future of Laboratory Revenue Cycle Management

Healthcare is consistently in demand, yet it can be unpredictable. So, proactively improving laboratory workflow management and efficiency should be at the top of any executive's checklist.

More specifically, incorporating advanced laboratory billing solutions, such as those offered by LigoLab, can stabilize an organization's fiscal health and growth potential.

Although prior authorization can significantly hamper lab workflow efficiency, it is far from the only factor plaguing laboratory operations in today's industry landscape.

Modern laboratory billing features in LigoLab's "Single Source of Truth" Informatics Platform put laboratories in the driver's seat to streamline, standardize, and track lab workflow processes, such as prior authorization.
