What Happens After a Claim Is Submitted? Understanding the Medical Billing Process
When a medical claim is submitted to an insurance company, many healthcare providers assume the process is mostly complete. In reality, submitting the claim is only the beginning of a much larger process. What happens afterward determines whether the provider receives timely and accurate payment.
Understanding the steps that follow claim submission can help practices identify where delays, denials, and revenue loss often occur.
Claim Transmission and Initial Processing
Once a claim is submitted, it is typically sent electronically through a clearinghouse before reaching the insurance payer. The clearinghouse performs an initial review to check for formatting errors, missing information, or incorrect codes. If issues are detected, the claim may be rejected and returned to the provider for correction before it ever reaches the insurance company.
If the claim passes this stage, it is transmitted to the payer for review.
Insurance Adjudication
After the claim reaches the insurance company, it enters the adjudication process. During this stage, the payer reviews the claim to determine several key factors:
- Whether the patient was eligible for coverage on the date of service
- Whether the service is covered under the patient’s policy
- Whether the coding and documentation support the billed service
- Whether prior authorization was required and obtained
- Whether the provider is credentialed and in network
Based on this review, the insurance company determines the amount they will pay, if any.
Payment or Denial Determination
Following adjudication, the payer issues an Explanation of Benefits (EOB) or Electronic Remittance Advice (ERA). This document explains how the claim was processed and details:
- The amount billed by the provider
- The allowed amount under the payer’s contract
- The portion paid by the insurance company
- Any adjustments or contractual write-offs
- The remaining patient responsibility
If the claim is denied, the EOB or ERA will include a denial reason code explaining why the claim was not paid.
Posting Payments and Patient Billing
Once payment is received, the billing team posts the payment into the practice management system. Adjustments are applied according to the insurance contract, and any remaining balance becomes the patient’s responsibility.
At this point, a patient statement may be generated if a balance remains after insurance payment.
Denial Management and Follow-Up
Not all claims are paid on the first submission. Claims may be denied for reasons such as missing information, coding errors, lack of prior authorization, or credentialing issues.
A strong medical billing process includes consistent follow-up to:
- Correct and resubmit denied claims
- File appeals when appropriate
- Monitor aging accounts receivable
- Ensure claims are paid according to payer contracts
Without proper follow-up, unpaid claims can quickly become lost revenue.
Why the Post-Submission Process Matters
Many revenue challenges for healthcare practices occur after the claim is submitted. Delayed payments, unresolved denials, and missed follow-ups can significantly affect cash flow.
This is why an organized billing workflow, regular claim monitoring, and proactive follow-up are essential to maintaining a healthy revenue cycle.
