Claim Rejections vs. Claim Denials: Why Understanding the Difference Matters And How PayrHealth Helps You Manage Both

In a complex healthcare landscape, few issues impact your bottom line more than unresolved medical claims. Medical billing is a critical component of revenue cycle management, and while both claim rejections and claim denials disrupt cash flow, understanding the key differences between the two, and how to respond strategically, can make or break your revenue cycle performance.

At PayrHealth, we help providers streamline their billing operations. Our billing team plays a vital role in managing claim rejections and denials, reducing reimbursement delays, and strengthening their payer relationships. Below, we explore the differences between claim rejections and denials, and how our strategic guidance helps providers overcome both.

What Is a Claim Rejection?

A claim rejection occurs when a medical claim is not accepted for processing by the payer due to formatting errors, incomplete information, or noncompliance with X12 standards. Claim rejections often occur when errors found or one or more errors are present in the claim submissions, such as incorrect information or missing data. Rejected claims are returned without being entered into the payer’s adjudication system, meaning they were never truly “submitted” in the first place.

Common causes include:

·       Missing or incorrect patient data

·       Invalid or outdated CPT/ICD-10 codes

·       Incomplete documentation orattachments

·       Submission to the wrong payer

·       Lack of necessary information

·       Incorrect information

A submitted claim may be rejected if it does not contain the correct information or if it is a duplicate claim.

How PayrHealth Helps: We work with healthcare organizations to audit their submission workflows, implement front-end claim scrubbing protocols, and train staff on the most common rejection triggers, ensuring clean claims from the start. We also monitor for rejection notices and implement strategies to avoid rejections through accurate and complete claims submissions.

What Is a Claim Denial?

In contrast, a claim denial occurs after the payer has processed the claim and determined that it does not qualify for reimbursement. A denied claim means the insurance company has reviewed the claim and decided not to pay, often because the claim is deemed unpayable due to policy limits, lack of coverage for a specific service, or not meeting payer guidelines. Denials are often tied to medical necessity, policy limitations, or eligibility conflicts.

Typical denial reasons include:

·       Services not covered under thepatient’s plan

·       Lack of prior authorization

·       Timely filing violations

·       Coding discrepancies or conflicting diagnoses

·       Payer reviews found the claim did not meet guidelines

·       Services not considered a covered specific service

The insurance company may deny a claim after a thorough process involves reviewing the claim details, and providers receive an explanation or electronic remittance advice outlining the denial reasons.

Unlike rejections, denials cannot simply be resubmitted; they require an appeals process with supporting documentation, sometimes involving direct patient follow-up or clinical justification. To address a denied claim, providers may need to submit a corrected claim or a new claim with the necessary changes, and it is important to follow up to ensure the claim is paid.

PayrHealth’s Approach: Our team helps providers implement denial management workflows that prioritize root-cause identification, appeal readiness, and ongoing payer communication, turning more denials into recoverable revenue. We help providers address denied claims by interpreting payer reviews and explanations, and guide them through the corrected claim process.

Strategies to Prevent Rejected Claims

1.Validate Patient Data Early 

Ensure accuracy at intake, name, DOB, policy numbers, and insurance verification must be double-checked. Use integrated EHR or practice management systems to maintain up-to-date patient records. Verifying patient information and including all necessary information in claim submissions is essential to prevent rejections and ensure smooth processing.

2.Verify Eligibility Before Service 

PayrHealth helps clients implement real-time eligibility checks at both scheduling and check-in to prevent rejections tied to coverage lapses or plan mismatches.

3.Submit Complete, Accurate Claims 

Use automated tools to ensure all required documentation, such as referrals or test results, is attached. We also help optimize coding accuracy through team education and template management. Accurate documentation and providing correct information are essential for successful claims submissions and minimizing denials.

4.Avoid Duplicate Submissions 

Establish tracking protocols through clearinghouse portals to prevent accidental resubmission of the same claim. Duplicate claim errors are common, so tracking and monitoring are critical to avoid submitting claims more than once.

5.Manage Coordination of Benefits (COB) 

Train front-office teams on COB processes and ensure the correct primary payer is always identified.

Conducting regular audits of claim submissions helps ensure accuracy, compliance, and early identification of issues in the claims process.
