What Are the Two Most Common Claim Submission Errors?

The two most common medical claim submission errors are incorrect patient or insurance information and medical coding errors. For healthcare practices, these mistakes can lead to rejected claims, delayed insurance payments, preventable denials, and additional billing work. Accurate claim preparation, eligibility verification, and pre-submission reviews can help identify problems before claims reach the payer.

If your practice is experiencing recurring claim rejections, rising accounts receivable, or repeated coding corrections, professional medical billing services can help identify process gaps and improve claim accuracy. The Medicator’s supports healthcare practices with medical billing, coding, claim review, denial prevention, and revenue cycle management services.

What Are the Two Most Common Medical Claim Submission Errors?

The two major categories are inaccurate patient or insurance information and medical coding errors. Both can prevent an otherwise legitimate claim from being processed correctly.

1. Incorrect Patient and Insurance Information

Incorrect demographic or insurance information can cause a claim to fail payer identification and eligibility checks. A claim may contain the correct services and diagnosis but still encounter processing problems if the patient’s information does not match the payer’s records.

Common claim submission data errors include:

• Misspelled patient names or incorrect dates of birth
• Incorrect member ID or insurance policy numbers
• Outdated insurance coverage information
• Incorrect payer selection or billing order
• Missing subscriber details or incorrect patient relationships
• Mismatched patient, policyholder, or insurance records
• Incorrect billing or rendering provider identifiers

How to prevent these errors: Verify patient demographics and active coverage, confirm the correct payer, and review the information before submitting the claim. Practices can strengthen this process through insurance eligibility verification services.

For clinics managing a high volume of claims, outsourcing medical billing support may help establish consistent verification and claim-review workflows. Eligibility verification does not guarantee payment, so coverage, authorization, documentation, coding, and payer requirements must also be reviewed.

2. Medical Coding and Claim Detail Errors

Medical coding errors occur when the codes or other billing details submitted do not accurately represent the services documented in the medical record or do not meet applicable payer requirements.

Common coding and claim detail errors include:

• Incorrect or insufficiently specific ICD-10-CM diagnosis codes
• Incorrect CPT or HCPCS procedure codes
• Missing or unsupported modifiers
• Diagnosis and procedure code mismatches
• Incorrect units, dates of service, or place-of-service details
• Missing documentation or required signatures
• Incorrect bundling or unbundling of services
• Coding that is not supported by the clinical record

How to prevent these errors: Compare the reported codes with the medical record, check modifier and payer-specific requirements, and use a structured claim-scrubbing process before submission. A professional medical billing audit can help identify repeated coding and billing issues across a sample of claims.

Coding accuracy is not simply about choosing a code. The claim must reflect the services actually provided, be supported by documentation, and comply with the applicable coding and payer rules.

What Other Medical Claim Submission Errors Cause Rejections and Denials?

Patient information and coding are two major error categories, but other problems can also interrupt reimbursement. Practices seeking medical claim error prevention services should review the entire submission process, not just the diagnosis and procedure codes.

The exact outcome depends on the payer, claim type, and circumstances. A clearinghouse rejection is not the same as a payer denial: a rejection often means a claim failed an initial format or data validation check, while a denial generally means the payer processed the claim and determined that payment would not be made as billed.

For practices facing repeated issues, medical billing services can support claim preparation and follow-up, while revenue cycle management services can help connect front-end verification, coding, submission, denial follow-up, and accounts receivable workflows.

How Do Claim Submission Errors Affect Practice Revenue?

An isolated error may be easy to correct. Repeated errors across hundreds of claims can create a much larger operational and financial problem.

Common consequences include:

• Delayed reimbursement and unpredictable cash flow
• More rejected and denied claims requiring staff attention
• Growing accounts receivable and unresolved balances
• Additional work to correct, resubmit, or appeal claims
• Missed filing deadlines while claims are being investigated
• Underpayments or missed reimbursement opportunities
• Reduced visibility into the actual causes of billing problems

When the same error keeps appearing, correcting each claim individually may not solve the underlying issue. Practices need to identify whether the root cause is patient registration, eligibility verification, documentation, coding, payer setup, or the claim submission workflow.

This is where medical billing audit services can help. An audit can review claim samples, coding accuracy, documentation, denials, and payment activity to identify recurring patterns and recommend corrective action.

How Can Healthcare Practices Prevent Claim Submission Errors Before Billing?

A reliable process combines front-end verification, accurate coding, documentation checks, and ongoing review. Practices looking for medical billing claim review services can use the following checklist to strengthen quality control.

1. Verify Patient Demographics and Insurance

Confirm the patient’s name, date of birth, member ID, payer, coverage dates, and other relevant policy details. Recheck information when coverage changes or the eligibility response is unclear.

2. Confirm Authorization and Referral Requirements

Check whether the planned service requires authorization or a referral. Confirm that any approval matches the service, provider, location, and applicable dates.

3. Validate Medical Coding and Documentation

Review CPT, ICD-10-CM, and HCPCS codes as applicable. Confirm that the documentation supports the billed service, diagnosis specificity, modifiers, units, and other required details.

4. Scrub Claims Before Submission

Use claim edits and manual review to identify missing fields, inconsistent information, invalid codes, and potential payer-specific errors. Automated edits are useful, but exceptions may still require a knowledgeable billing professional.

5. Submit Claims to the Correct Payer

Confirm payer routing, billing order, provider identifiers, and submission requirements. Maintain a record of claim transmission and acceptance so rejected claims can be identified promptly.

6. Monitor Rejections and Denials

Review clearinghouse rejections and payer responses regularly. Correct the original issue, follow the payer’s requirements for corrected claims or appeals, and monitor filing deadlines.

7. Track Repeated Error Patterns

Group errors by root cause, payer, service type, provider, and workflow stage. Use the results to update staff procedures, training, and pre-submission checks.

8. Schedule Regular Billing Audits

Review a representative sample of claims and compare billed services, supporting documentation, payer responses, and payments. A recurring audit can help identify errors that are difficult to see when each claim is handled separately.

For practices that need ongoing support, The Medicator’s medical billing services can help manage claim preparation and submission workflows, while billing audits can identify areas for improvement.

When Should a Practice Outsource Medical Billing and Claim Submission?

Outsourcing may be worth evaluating when internal staff spend excessive time correcting claims, coding issues recur, denial follow-up falls behind, or accounts receivable continues to age without clear explanations.

Consider professional medical billing and claim submission support if your practice:

• Experiences recurring claim rejections or preventable denials
• Needs more consistent eligibility verification and coding reviews
• Has limited staff capacity for claim submission and payer follow-up
• Cannot identify the main causes of lost or delayed reimbursement
• Needs an independent review of its billing workflow
• Wants to improve visibility into claims, payments, and outstanding A/R

The right service depends on the underlying problem. A practice with isolated coding issues may benefit from a focused billing audit, while a practice struggling across registration, submission, denials, and A/R may need broader revenue cycle management support.

Before choosing a service, ask for a review of your current process, the scope of work, reporting methods, and how recurring errors will be identified and addressed.

Frequently Asked Questions About Medical Claim Submission Errors

What are the two most common claim submission errors?

The two most common categories are incorrect patient or insurance information and medical coding errors. Practices can reduce these problems by verifying demographics and coverage, checking coding and documentation, and reviewing claims before submission. Professional medical billing services can help establish a consistent workflow.

How can medical billing services help reduce claim submission errors?

Medical billing services can support claim preparation, coding review, eligibility checks, claim scrubbing, submission tracking, and follow-up. The appropriate scope depends on the practice’s workflow and the source of its errors. A medical billing audit can help identify recurring issues before selecting a solution.

What is the difference between a claim rejection and a claim denial?

A rejection commonly occurs when a claim fails an initial data or format check and cannot proceed as submitted. A denial generally occurs after payer processing, when the payer determines that the claim is not payable as billed. The correction process depends on the reason and the payer’s instructions. Ongoing revenue cycle management support can help practices track and address both types of problems.

Can a medical billing audit identify recurring claim submission errors?

Yes. A well-designed audit can examine claim data, documentation, coding, payer responses, and payment activity to identify patterns such as repeated demographic errors, coding inconsistencies, or missed workflow checks. Explore medical billing audit services to discuss a review of your practice’s billing process.

How can a practice reduce claim denials before submission?

Start with accurate patient registration, eligibility verification, authorization checks, complete documentation, correct coding, and pre-submission claim review. Track rejections and denials by root cause so the practice can correct the underlying process rather than repeatedly fixing individual claims. Practices can request a Free Practice Billing Analysis to discuss potential improvements.

When should a healthcare practice consider outsourced medical billing?

Consider outsourced medical billing when internal resources are stretched, claim corrections are recurring, denial follow-up is delayed, or the practice lacks clear reporting on unpaid claims. A review of the current workflow can help determine whether targeted coding support, a billing audit, or broader medical billing services are the best fit.

Final Takeaway

Incorrect patient or insurance information and medical coding errors are two major sources of medical claim submission problems. Preventing them requires a repeatable process for verifying coverage, reviewing documentation, validating codes, checking claim details, and monitoring payer responses.

If your practice continues to experience avoidable rejections, delayed reimbursement, or unresolved billing issues, investigate the root causes rather than treating each claim as an isolated problem. The Medicator’s can help you evaluate your billing workflow and identify opportunities for more consistent claim processing.
