If a patient is receiving treatment for Type 2 diabetes and has frequent routine checkups, they may find that their insurance claim is denied after a few visits. This could be due to a medical coder accidentally using the wrong diagnostic code or incorrect patient information. Such a small mistake can cause a significant delay in reimbursement.

Therefore, understanding the claim submission process is like threading a needle—it often requires expertise, patience, and careful attention to detail. Tools like Practice Management Software (PMS) and Electronic Health Records (EHR) help healthcare providers reduce human errors and manage the claim submission workflow more easily. Whether you run a large healthcare practice, a clinic, or a small practice, understanding the claim submission process is key to keeping everything running smoothly.

Understanding Claim Submission

Claim submission is the core of the medical billing process, ensuring that healthcare practices receive timely reimbursement for the services provided to their patients. Any errors or misinformation in the claim submission process can lead to payment delays or even claim denials.

As a healthcare provider, do you know why “clean claims” matter so much? What happens when you submit claims with a First Pass Resolution Rate (FPRR) over 97%? Think about how it could transform your practice’s efficiency and revenue.

This blog will guide you toward achieving “Claim Submission Excellence” by improving your FPRR.

Important Components of Medical Claim

Understanding the important components of a medical claim is essential for accurate and timely reimbursement. These components form the foundation of medical claims, with each conveying necessary information to insurance providers. Therefore, a well-structured claim not only ensures smooth processing but also reduces the likelihood of denials, providing healthcare providers with prompt compensation.

Claim Header Information

Complete Guide to the 7-Step Claim Submission Process

The claim submission process for medical billing involves multiple steps to ensure healthcare providers receive payment for the services they provide to patients. This process requires accuracy and attention to detail to minimize claim rejections, while also considering the experience of both healthcare providers and patients.

1). Patient Registration

The initial and important step in claim submission is patient registration. It involves collecting all relevant information about the patient, such as personal details, medical history, and insurance coverage. During this step, staff must cross-verify patient information, including name, address, contact details, and insurance policy number. Any errors in patient registration can lead to claim denials or delays later in the process.

Additionally, it is important to obtain the patient’s consent for treatment and acknowledgment of privacy policies. Ensuring that all details are accurately recorded during patient registration helps pave the way for smooth claim submission processing.

2). Insurance Eligibility Verification

Insurance eligibility verification is an important process for confirming a patient’s insurance coverage before any services are provided. This step involves contacting insurance providers to verify coverage limits, patient benefits, and co-payments or deductibles (if applicable). Upfront eligibility verification can prevent the provision of services that are not covered under the policy, avoiding potential financial losses. This verification is typically done through electronic methods, which can speed up the process and reduce errors.

According to the Healthcare Information and Management Systems Society (HIMSS), eligibility criteria and verification are effective ways to reduce claim denials.

3). Coding of Diagnosis and Procedures

The assignment of medical codes is a highly detailed task that involves translating medical diagnoses and services into standardized codes, such as ICD, CPT, or HCPCS. Correct coding is crucial because these codes determine the reimbursement amount from insurance providers. Incomplete or incorrect coding can lead to claim denials and payment delays. According to the Health Financial Management Association (HFMA), 42% of claims are denied due to incorrect coding.

4). Charge Capture and Entry

Charge capture and entry involve making a record of all billable services provided to patients- such as; documentation of procedures, consultations, lab tests and other healthcare services. Inaccurate charge capture, no services are overlooked, which is important for an increase in revenue. This step can be done through an EHR system that can make the process error-free and smooth. Charge capture not only impacts the revenue cycle but also ensures compliance with healthcare regulations by providing a complete detail of services rendered.

5). Claim Generation

Claim generation is a critical step because it includes compilation of all important information like insurance details, demographics and coded medical services into a formal claim. The data should be in a format that meets all requirements of insurance providers. Proper claim generation ensures that all information is in the right format as per insurance provider guidelines to avoid rejections. It’s important to use EHR and PMS that can meet industry standards like the Health Insurance Portability and Accountability Act (HIPAA) to facilitate secure transmission of medical claims.

6). Claim Scrubbing

The claim scrubbing is an important step in terms of finalization of medical claim- a thorough review of claim can be done to mark red flags or any inconsistency before submission. You can scrub your claims through AAPC CMS 1500 Real-Time Scrubber that can pinpoint and fix those issues before claim submission. Errors that can commonly identify during claim scrubbing are spotted in ; patient information, medical codes, super bills and claim form. The AAPC and AMA put more emphasis on claim scrubbing, which can reduce claim denials and improve the overall efficiency of the claim submission process.

7). Claim Submission

Claim submission is the final step, where the finalized claim is sent either electronically or through paper submission. Claims can be submitted using standardized electronic formats, such as HIPAA-compliant 837 files, which ensure secure data transfer. Timely submission of claims is important to maintain cash flow and avoid payment delays.

According to the Workgroup for Electronic Data Interchange (WEDI), e-claim submission helps healthcare providers reduce administrative burdens and increase the speed of claim processing, ensuring timely reimbursement.

What Happens After Claim Submission?

The process doesn’t end with claim submission. After submission, the process continues to ensure that the claim is properly processed, paid, and reconciled correctly.

Follow-up and Reconciliation

Follow-up and reconciliation is an ongoing process that involves tracking the status of submitted claims and addressing any issues that arise. This step includes checking the payment status, processing timeline, and claim acceptance. Effective follow-up takes immediate action to resolve claim denials, which is crucial for maintaining steady cash flow. Reconciliation helps track the healthcare provider’s financial records and identify outstanding payments or errors.

Claim Payment Posting

Claim payment posting is the “happy ending” for healthcare providers. Once the insurance provider processes the claim and issues payment, the payment is deposited. This includes posting payment details, reconciling the amount with the expected reimbursement rate, and addressing any discrepancies. Accurate payment posting ensures that the healthcare provider’s accounts are balanced and patient bills are correctly paid. This step marks the conclusion of the claim submission process.

Error-Free Claim Submission Methods

For healthcare providers, it’s vital to ensure that all medical bills are processed effectively. There are different claim submission methods to meet the needs of various healthcare practitioners. Healthcare providers can process claim submissions through Electronic Data Interchange (EDI), Direct Data Entry (DDE), or traditional paper submission. Below is an overview of these methods to help you submit bills successfully.

✅️ Electronic Data Interchange (EDI) Submission

Electronic Data Interchange (EDI) X12 is a standardized data format that allows healthcare practices to exchange patient data electronically. This method eliminates the need for paper submissions and reduces workload. The advantages of EDI submission include:

• Faster and more accurate submissions, reducing claim processing delays.
• Lower administrative costs by saving on materials, management, and postage.
• Faster payments by speeding up the reimbursement process.
• Immediate error detection, enabling quick identification and resolution of issues.

The Workers’ Compensation Medical Bill Processing (WCMBP) system can process various EDI transaction files, such as:

• 837 Inbound File: Contains complete patient information sent to insurance payers.
• 835 Outbound File: Contains Electronic Remittance Vouchers (RV) or Explanation of Benefits (EOB) sent to healthcare providers.
• TA1 Outbound Acknowledgement: Confirms receipt and status of claim processing.
• 999 Outbound Acknowledgement: Confirms proper receipt of the file.

Outpatient bills with types 13x or 14x require a Medicare number. To avoid claim rejection, always cross-verify the case ID and Date of Birth (DOB).

✅️ Direct Data Entry Submission

Direct Data Entry (DDE) allows healthcare providers to submit bills directly into the Workers’ Compensation Medical Bill Processing (WCMBP) system. This method supports institutional, dental, and professional bills. By entering bills directly into the system, healthcare providers can quickly receive error notifications and make corrections. The benefits of using DDE for claim submission include:

• Instant identification of red flags, allowing healthcare providers to make immediate corrections and avoid delays.
• Easy access to payment amounts, denial reasons, and Remittance Voucher (RV) details.
• The ability to attach supporting documentation to prevent duplicate service denials. For outpatient bills with types 13x or 14x, include the Medicare number in block 51B on the UB-04 form.

Timely claim submission is important, so ensure all documentation, like the EOB or RTP letter, is attached.

✅️ Paper Submission

Healthcare providers can also choose paper submission as an alternative to EDI and DDE methods. Paper claims can be submitted through the WCMBP portal, printed, and mailed to the Office of Workers’ Compensation Programs (OWCP) mailroom. After submission, the claims can be:

• Scanned for conversion into digital format.
• Imaged for easy access and review.
• Reviewed for accuracy and completeness.

Once processed at the mailroom, these claims are entered into the WCMBP system for evaluation and payment. If the claim form is incomplete or contains errors, it will be returned to the healthcare provider with a Return to Provider (RTP) notice, explaining the reason for the return.

To avoid RTP notices:

• Ensure all fields on the form are filled out correctly.
• Verify that the OWCP provider ID is active.
• Complete the ICD indicator field properly.
• Cross-check information such as DOB, case ID, and other details for accuracy.
