10 Essential Steps in the Laboratory Billing Process

In healthcare billing, preventing reimbursement delays is a top priority, but it’s an issue that many healthcare providers continue to struggle with. According to the American Medical Association (AMA), denials of processed claims—claims that are never paid—have risen to 11% of all claims. This translates into 110,000 unpaid claims for an average-sized health system, creating significant financial strain and operational bottlenecks. These reimbursement delays don’t just impact the bottom line; they also affect the cash flow and overall financial health of healthcare providers. However, by mastering the essential steps in the laboratory billing process, providers can reduce billing errors, avoid claim denials, and ensure timely reimbursements. 

In this blog, we will explore practical strategies to minimize claim denials and optimize your revenue cycle management.

What is the Laboratory Billing Process?

The laboratory billing process involves a series of steps where a physician orders a lab test, the lab performs the test, and the payer (like an insurance company) reimburses the lab for the services provided. This process can take days or even months, and often requires multiple interactions between the physician, lab, and payer.

Laboratories typically have dedicated teams to handle billing and coding. These teams ensure that lab tests are properly coded, claims are submitted to the payer, and any denials are addressed. It begins with accurate coding of laboratory tests and services, followed by claim submission, verification of insurance coverage, and processing by payers. 

Key Roles in the Laboratory Billing Process

• Physicians: Physicians order the necessary laboratory tests based on a patient's medical needs, ensuring that the tests performed are medically necessary.
• Laboratory Staff: Laboratory staff are responsible for conducting the tests accurately, and the results are crucial for the patient's diagnosis and treatment. These results also contribute to 70-80% of the content in Electronic Health Records (EHRs).
• Lab Billers and Coders: Lab billers and coders play a critical role in optimizing the billing process. They translate the laboratory services into the appropriate CPT codes, ensuring accuracy and compliance in claims.
• Insurance Companies: Insurance companies receive the claims submitted by the laboratory, reviewing them to determine the appropriate reimbursement based on the lab’s CPT codes and the patient’s insurance coverage.

These key players collaborate to ensure the smooth operation of the laboratory billing process, reducing errors and improving the efficiency of revenue cycle management.

Why the Laboratory Billing Process is Important

The laboratory billing process plays a vital role in ensuring smooth financial operations for healthcare facilities. Here’s why:

• Timely Payments: Accurate billing ensures timely payments and reduces delays in reimbursements, preventing disruptions to cash flow.
• Compliance: Adhering to payer guidelines and coding standards protects labs from penalties and audits, ensuring they remain compliant and maintain their reputation.
• Improved Cash Flow: Efficient billing reduces bottlenecks in the revenue cycle, promoting steady and predictable financial health for healthcare facilities.
• Reduced Claim Denials: Submitting accurate claims minimizes the chances of rejections, rework, and appeals, saving time and resources for the laboratory.

10 Essential Steps in the Laboratory Billing Process

Successfully managing the laboratory billing process requires a clear understanding of each key step, ensuring accuracy and efficiency from patient registration to final payment.

Step 1: Patient Registration and Information Gathering

The first step in the laboratory billing process begins even before the patient’s test is ordered. Accurate patient registration is crucial for smooth billing. This involves collecting and verifying demographic and insurance information. The patient’s full name, address, phone number, date of birth, and primary insurance details should be correctly entered into the system.

To prevent billing errors, healthcare providers must double-check that the patient’s insurance information is up-to-date and matches the coverage information. Any discrepancies at this stage can lead to denials later in the process.

Step 2: Verify Patient Eligibility and Benefits

Before any laboratory services are performed, verifying patient eligibility and benefits is vital. By confirming that the patient’s insurance is active and that the services are covered, you can avoid costly billing mistakes. This step helps determine whether the patient’s insurance will cover the tests and services, and if there will be any co-pays, deductibles, or out-of-pocket expenses.

Using automated eligibility verification tools integrated with the practice management system can save time and reduce the risk of human error. These systems provide real-time information about coverage, ensuring that all services rendered are covered by the patient's plan.

Step 3: Order and Perform Laboratory Tests

Once the patient’s insurance eligibility is confirmed, the laboratory tests can be ordered and performed. Accurate documentation of the tests ordered by the physician is crucial for ensuring that the right tests are billed correctly.

Each test must be properly documented, including the type of test, reason for the test, and any special instructions. Incomplete or inaccurate test orders can result in claims being rejected or denied, leading to unnecessary delays in reimbursement.

Step 4: Proper Coding of Laboratory Services

Coding is one of the most crucial steps in the laboratory billing process. Accurate coding ensures that the correct procedure is linked to the patient’s diagnosis and that the insurance company can process the claim. Laboratory billing uses a combination of ICD-10 (diagnosis codes) and CPT (procedure codes) to describe the patient’s condition and the tests performed.

CPT codes identify the laboratory tests and procedures, while ICD-10 codes are used to document the medical reason for the tests. Both sets of codes must be accurate to avoid denials. Inaccurate or outdated codes may lead to payment delays or claims rejection.

Step 5: Documentation of Test Results

Once the laboratory tests have been completed, it is essential to document and report the results clearly and accurately. This includes providing detailed information about the findings, any abnormalities, and the interpretation of the results by the physician or healthcare provider.

Proper documentation of test results is critical for supporting the diagnosis and demonstrating the medical necessity of the tests. Lack of sufficient documentation can lead to denials from insurance companies, as they may consider the services unnecessary or unsupported.

Step 6: Review of Test Results for Medical Necessity

Before submitting a claim, it’s essential to review the laboratory results and ensure they align with medical necessity guidelines. Insurance companies require that the tests be medically necessary, and they may deny claims for tests that aren’t supported by clinical evidence.

By ensuring that the laboratory tests performed are necessary based on the patient’s condition, you can reduce the chances of denials. This may involve additional clinical documentation or clarifications to confirm the necessity of the tests.

Step 7: Preparation of Billing Information

Once all the test results and necessary documentation are gathered, the next step is to prepare the billing information. This involves compiling all the relevant codes, patient details, insurance information, and any additional documentation required by the payer.

Accuracy is crucial at this stage to ensure that the claim is processed without errors. Any mistakes in the preparation can result in delays, rejections, or incorrect reimbursements.

Step 8: Submit the Claim

The next step is to submit the claim to the insurance company or third-party payer. This can be done electronically via an EDI (Electronic Data Interchange) system or manually by paper submission. Electronic claims are faster and less prone to errors, so healthcare providers should prioritize electronic submissions where possible.

Ensure that the claim includes all relevant information, including patient details, test results, and supporting documentation. The more complete the claim, the less likely it is to be rejected or delayed.

Step 9: Payment Posting and Tracking

Once the claim is submitted, the next step is to track the payment. This involves posting payments as they are received from the payer and reconciling them with the original claim. If the payment is less than expected, it’s crucial to identify the discrepancy and address it promptly.

Healthcare providers should also keep track of partial payments or denials, as these may require follow-up action.

Step 10: Denial Management and Appeals

Despite careful planning, some claims may still be denied. This is where an effective denial management process comes into play. When a claim is denied, healthcare providers must quickly analyze the reason for the denial, correct any errors, and submit an appeal.

The appeals process should be structured, with clear steps to ensure that all necessary documentation is included. Promptly addressing denied claims reduces the administrative burden and helps ensure that healthcare providers are reimbursed in a timely manner.
