Understanding the common causes of claim rejections is essential for reducing revenue loss. Claim Rejections remain one of the most frustrating challenges for healthcare providers. They slow down the revenue cycle, increase administrative burden, and negatively affect cash flow. According to the American Medical Association, nearly 1 in 10 medical claims face issues at the first submission stage. While some of these problems arise from payer-specific rules, the majority of rejections occur due to preventable mistakes such as incorrect patient data, insurance errors, or coding inconsistencies.
May Medical Solutions specializes in addressing these issues through advanced technology, systematic workflows, and experienced billing experts. By understanding the most common causes of claim rejections, providers can implement preventive strategies that ensure clean claim submissions, reduced revenue leakage, and faster reimbursements.
This blog highlights the most frequent reasons for claim rejections in healthcare billing and outlines how May Medical Solutions helps providers overcome these challenges with long-term solutions.
Cause 1: Incorrect Patient Details
One of the simplest yet most frequent errors in medical billing is inaccurate patient information. Something as small as a misspelled name, incorrect birthdate, or mismatched policy number can lead to instant claim rejection. Since clearinghouses and payers rely on accurate demographic data to validate claims, even a single character error may cause mismatches in payer databases.
Solution:
At May Medical Solutions, we use real-time patient data verification tools that cross-check demographics and insurance information before claims are submitted. By validating patient details early in the process, providers avoid unnecessary rejections and speed up their revenue cycle.

Cause 2: Invalid Insurance Information
Submitting claims with outdated, incorrect, or expired insurance details is another major cause of rejection. Claims often bounce back when practices fail to update payer information or confirm eligibility before appointments.
Solution:
Our team ensures insurance verification prior to every visit, confirming coverage status, payer ID, and coordination of benefits. By verifying active coverage and ensuring the correct payer is billed, May Medical Solutions helps reduce rejections due to insurance errors.

Cause 3: A Leading Example of Common Causes of Claim Rejections
Among the common causes of claim rejections, invalid insurance information remains one of the top issues. Medical coding errors are consistently ranked among the top reasons for claim rejections. Incorrect CPT, ICD-10, or HCPCS codes, outdated code sets, or improper modifier usage can immediately disqualify a claim.
Solution:
We employ certified medical coders who stay updated with the latest coding guidelines and payer-specific rules. In addition, our AI-powered claim scrubbing tools detect potential coding errors before submission, significantly improving first-pass acceptance rates.

Cause 4: Missing Required Documentation
Some medical procedures require prior authorization, referral notes, or detailed clinical documentation. If these records are missing, the claim is often rejected.
Solution:
We integrate directly with EHR systems to maintain payer-specific documentation checklists. This ensures that prior authorizations, clinical notes, and referral letters are always attached to the claim, minimizing rejection risks.
Cause 5: Filing Claims After Deadlines
Every payer sets strict deadlines for claim submissions, often between 30 to 365 days. Claims filed after the deadline are automatically rejected and usually non-recoverable.
Solution:
May Medical Solutions tracks payer-specific deadlines using automated claim tracking systems. This allows us to prioritize claims nearing their filing limits and prevent denials related to untimely filing.
Cause 6: Provider Credentialing and NPI Mismatches
Claims get rejected if the provider is not properly credentialed with the payer or if the National Provider Identifier (NPI) does not match payer records.
Solution:
We offer full credentialing and enrollment support, ensuring NPIs, taxonomy codes, and provider records remain updated with payers. This proactive approach prevents rejections due to mismatched or incomplete provider information.
Cause 7: Duplicate Submissions
Duplicate claim submissions often occur when claim status is unclear or when practices lack tracking systems. Payers reject duplicates even if the original claim is still under review.
Solution:
Our centralized claims management dashboard tracks submission status and payment updates in real-time. This prevents duplicate claim submissions and ensures transparency in the billing process.
Cause 8: Incomplete Service-Level Data
Missing or incorrect entries for dates of service, billed units, or place of service codes often cause rejections, particularly with strict commercial payers.
Solution:
We use pre-submission validation tools to check service-level data before sending claims. This ensures accuracy in dates, units, and codes, reducing the likelihood of rejection.

FAQ
1. What is a clean claim rate and why does it matter?
A clean claim rate measures the percentage of claims accepted and paid by insurers on the first submission without edits. A higher rate means faster reimbursements, less rework, and improved practice cash flow.
At May Medical Solutions, our processes consistently achieve a clean claim rate of over 98%.
2. What is the difference between a claim rejection and a claim denial?
- A claim rejection occurs when a payer refuses a claim due to data entry, formatting, or coding errors before it enters adjudication.
- A claim denial occurs when the claim is reviewed but refused for coverage reasons.
May Medical Solutions focuses on preventing rejections at the source while also managing denials effectively.
3. What KPIs should practices track to reduce claim rejections?
Key metrics include:
- First-pass resolution rate
- Rejection and denial rate by payer
- Days in Accounts Receivable (A/R)
- Average reimbursement per claim
- Timely filing compliance
May Medical Solutions provides custom KPI dashboards and reporting for continuous improvement.
4. How do No Surprises Act rules affect claim submissions?
The No Surprises Act requires accurate provider status, cost estimates for self-pay patients, and documentation of patient consent for certain services. Missing this information can cause claim rejections.
May Medical Solutions ensures full compliance with these regulations to protect both providers and patients.
