After a claim is submitted to insurance, the claim is checked for errors, accepted or rejected, reviewed by the payer, adjudicated for payment or denial, and returned with claim status, remittance, and patient responsibility details.
In healthcare, this is part of the health insurance claim process. A medical claim submitted to insurance does not go straight to payment. It moves through clearinghouse validation, payer adjudication, claim status tracking, ERA or EOB delivery, payment posting, denial management, and AR follow-up.
For healthcare providers, this process affects provider reimbursement, cash flow, claim resubmission, patient billing, and revenue cycle performance. A clean claim can move faster through payer review. A claim with missing patient data, coding errors, invalid insurance, or payer-specific issues can be rejected, denied, or delayed.
This guide explains what happens after an insurance claim is filed, how the claim submission process works, and what each insurance claim status means.
What Are the Main Stages After Claim Submission?
The main stages after claim submission are clearinghouse review, payer acceptance, payer adjudication, claim decision, remittance, payment posting, and follow-up.
| Stage | What Happens |
| Claim submission | Provider sends the claim through a billing system, clearinghouse, or payer portal |
| Clearinghouse review | Claim is checked for formatting, missing fields, and payer edits |
| Payer acceptance | Payer accepts the claim for review or rejects it for correction |
| Payer adjudication | Payer reviews eligibility, benefits, coding, authorization, and medical necessity |
| Claim decision | Claim is paid, denied, adjusted, pended, or assigned to patient responsibility |
| Remittance | Payer sends ERA, EOB, or payment details |
| Payment posting | Billing team records payment, denial, adjustment, and patient balance |
| AR follow-up | Unpaid, denied, underpaid, or pending claims are tracked until resolved |
What Is the Claim Submission Process?
The claim submission process is the workflow used to send a healthcare claim from the provider to the insurance payer for review and reimbursement.
A provider usually submits a claim after the patient visit has been documented, coded, and reviewed for billing accuracy.
A medical claim includes:
- Patient demographics
- Insurance information
- Provider NPI and tax ID
- Date of service
- CPT, ICD-10-CM, HCPCS, and modifier codes
- Billed charges
- Place of service
- Prior authorization when required
- Supporting documentation when needed
Most medical claims are submitted electronically. CMS explains that electronic claims can be submitted to Medicare Administrative Contractors using software that meets HIPAA claim standards and CMS requirements.
How Is a Medical Claim Sent to Insurance?
A medical claim is usually sent to insurance through a billing system, clearinghouse, or payer portal using an electronic claim transaction.
The main electronic claim transaction is EDI 837. The payment and remittance response is commonly sent through EDI 835.
| Transaction | Purpose | Direction |
| EDI 837P | Professional claim submission | Provider to payer |
| EDI 837I | Institutional claim submission | Facility to payer |
| EDI 835 | Payment and remittance response | Payer to provider |
CMS lists institutional, professional, and dental health claims under the ASC X12N 837 standard, while health care payment and remittance advice uses the 835 standard.
What Does a Clearinghouse Do After Claim Submission?
A clearinghouse checks the claim for formatting, missing data, payer rules, and basic billing errors before sending it to the insurance payer.
The clearinghouse acts as a bridge between the provider and payer. It reviews the claim before payer adjudication begins.
A clearinghouse may check:
- Patient name and date of birth
- Insurance member ID
- Payer ID
- Provider NPI
- Diagnosis and procedure code logic
- Modifier rules
- Duplicate claims
- Required authorization fields
- Payer-specific edits
If the claim passes clearinghouse edits, it moves to the payer. If it fails, the claim may be rejected and returned to the billing team for correction.
What Happens Immediately After a Claim Is Submitted?
After a claim is submitted, the clearinghouse or payer validates the claim and decides whether it can enter the claim adjudication process.
| Claim Status | Meaning | Next Action |
| Accepted | Claim passed initial validation | Wait for payer adjudication |
| Rejected | Claim failed basic validation | Correct and resubmit |
| Pending | Claim is under payer review | Monitor claim status |
| Denied | Payer reviewed and refused payment | Review denial and appeal if needed |
| Paid | Payer approved payment | Post payment and bill patient if needed |
A claim can appear submitted but still need correction before full payer review. This is why insurance claim status tracking is important.
What Is Payer Adjudication?
Payer adjudication is the insurance company’s review process that determines whether a claim is paid, denied, adjusted, pended, or assigned to patient responsibility.
During payer adjudication, the insurance payer compares the claim against the patient’s plan, payer rules, and provider contract.
| Review Area | What the Payer Checks |
| Eligibility | Was coverage active on the date of service? |
| Benefits | Is the service covered by the plan? |
| Coding | Do diagnosis and procedure codes match? |
| Medical necessity | Does documentation support the service? |
| Authorization | Was prior authorization required and approved? |
| Contract terms | What is the allowed amount? |
| Patient responsibility | What applies to deductible, copay, or coinsurance? |
The claim adjudication process decides how much the payer will pay, what will be adjusted, and what the patient may owe.
What Is the Difference Between Claim Accepted vs Rejected?
A claim accepted by insurance has passed initial validation, while a rejected claim failed before full payer adjudication.
| Factor | Accepted Claim | Rejected Claim |
| Meaning | Claim entered payer workflow | Claim failed validation |
| Timing | Before adjudication continues | Before full payer review |
| Common cause | Valid claim format | Missing or incorrect data |
| Next step | Wait for payer decision | Correct and resubmit |
| Revenue impact | Payment process continues | Payment is delayed |
A rejected claim is often caused by preventable errors, such as an invalid member ID, missing diagnosis code, wrong payer ID, or incorrect provider details.
What Is the Difference Between Claim Rejection and Claim Denial?
A claim rejection happens before payer adjudication, while a claim denial happens after payer review and refusal of payment.
| Factor | Claim Rejection | Claim Denial |
| Timing | Before adjudication | After adjudication |
| Main cause | Missing data or invalid format | Coverage, coding, authorization, or medical necessity issue |
| Fix | Correct and resubmit | Appeal, correct, or send documentation |
| Revenue risk | Payment delay | Possible revenue loss |
| Billing action | Claim resubmission | Denial management |
Rejected claims usually need correction. Denied claims may need medical records, appeal letters, payer calls, or formal dispute steps.
Why Is an Insurance Claim Pending?
An insurance claim is pending when the payer has received the claim but has not made a final payment, denial, or adjustment decision.
A pending insurance claim can happen because of:
- Manual payer review
- Medical necessity review
- Missing documentation
- Prior authorization review
- Coordination of benefits
- Duplicate claim check
- Payer system delay
- Additional records request
- Provider contract review
A pending status does not always mean the claim is denied. It means the payer has not completed adjudication yet.
What Happens After the Payer Makes a Decision?
After the payer makes a claim decision, it sends payment, denial, adjustment, or patient responsibility details through an ERA, EOB, or remittance document.
For providers, the payer response often appears as an ERA in medical billing through an EDI 835 transaction. CMS states that after Medicare processes a claim, an Electronic Remittance Advice or Standard Paper Remittance provides final claim adjudication and payment information.
The payer response may include:
- Allowed amount
- Paid amount
- Contractual adjustment
- Denial code
- Remark code
- Deductible
- Copay
- Coinsurance
- Patient responsibility
- Secondary payer information
This payer decision controls payment posting, patient billing, denial management, and AR follow-up.
What Is an EOB After Claim Submitted?
An EOB after claim submitted is an Explanation of Benefits that tells the patient how the insurance company processed the claim.
An EOB is not always a bill. It shows what the provider charged, what insurance allowed, what insurance paid, and what the patient may owe.
| Item | EOB | ERA |
| Full Name | Explanation of Benefits | Electronic Remittance Advice |
| Main User | Patient | Provider or billing team |
| Purpose | Explains claim result | Supports payment posting |
| Includes | Allowed amount, paid amount, patient responsibility | Payments, adjustments, denial and remark codes |
| Format | Paper or digital notice | Electronic 835 transaction |
CMS describes an ERA as an explanation from a health plan to a provider about a claim payment, including claim charge adjustments related to contract agreements, secondary payers, coverage, copays, and coinsurance.
How Does Payment Posting Work After Claim Adjudication?
Payment posting records the payer’s payment, adjustment, denial, and patient responsibility in the provider’s billing system.
The payment posting team reviews ERA, EOB, and payer remittance information. Then it posts the correct amounts to the patient account.
Payment posting includes:
- Insurance payment
- Contractual adjustment
- Denial code
- Remark code
- Deductible
- Copay
- Coinsurance
- Patient balance
- Underpayment
- Secondary insurance balance
Accurate payment posting prevents incorrect patient bills, missed underpayments, unresolved denials, and inaccurate AR reports.
What Is 276 277 Claim Status?
276 277 claim status refers to electronic claim status request and response transactions used to check where a submitted claim stands.
A 276 transaction is a claim status request. A 277 transaction is the payer’s claim status response. CMS includes claim status request and response under its electronic billing and EDI transaction resources.
These transactions help providers track:
- Accepted claims
- Pending claims
- Paid claims
- Denied claims
- Claims needing more information
- Claims not found in payer records
This process supports AR follow-up and reduces unnecessary payer calls.
Practical Example: What Happens After a Claim Is Filed?
A submitted medical claim moves from clearinghouse validation to payer adjudication, remittance, payment posting, and follow-up.
Example:
A provider submits a clean 837P claim for an office visit through a clearinghouse. The clearinghouse checks the claim for missing data, payer ID, provider NPI, diagnosis codes, CPT codes, and modifier rules. The claim passes validation and moves to the payer.
The payer reviews eligibility, benefits, coding, medical necessity, and patient responsibility. After adjudication, the payer sends an 835 remittance with the paid amount, contractual adjustment, and deductible balance. The billing team posts the payment and bills the patient for the remaining deductible.
If the payer denies the claim instead, the billing team reviews the denial reason, corrects the issue, sends documentation, files an appeal, or submits a corrected claim.
What Happens If the Claim Is Denied?
If the claim is denied, the provider or patient must review the denial reason, correct the issue, submit documentation, file an appeal, or send a corrected claim.
Common denial reasons include:
- Inactive insurance
- Missing authorization
- Non-covered service
- Medical necessity issue
- Coding error
- Missing modifier
- Duplicate claim
- Timely filing issue
- Coordination of benefits problem
Healthcare.gov explains that consumers can appeal insurance company decisions, and internal appeals generally must be filed within 180 days of receiving notice that a claim was denied.
For providers, denial management includes reviewing denial codes, gathering medical records, submitting corrected claims, filing appeals, and tracking payer responses.
What Happens If the Claim Needs Resubmission?
Claim resubmission happens when a rejected, corrected, or denied claim must be sent back to the payer with updated information.
A claim may need resubmission when:
- Patient data was wrong
- Insurance information changed
- CPT or ICD-10-CM codes were corrected
- Modifier details were missing
- Authorization information was added
- Documentation was attached
- The payer requested a corrected claim
A resubmitted claim must be tracked carefully. If the same error repeats, the claim may delay payment again or miss payer filing deadlines.
How Does AR Follow-Up Work After Claim Submission?
AR follow-up tracks unpaid, pending, denied, underpaid, and delayed claims until the account is resolved.
The AR team reviews claim status, payer responses, aging reports, and payment posting records.
AR follow-up includes:
- Checking insurance claim status
- Reviewing 276/277 responses
- Calling payer representatives
- Sending medical records
- Filing appeals
- Submitting corrected claims
- Reviewing underpayments
- Billing secondary insurance
- Moving balances to patient responsibility
Strong AR follow-up protects provider reimbursement because it prevents submitted claims from sitting unpaid without action.
How Can Providers Speed Up the Insurance Payment Process?
Providers speed up the insurance payment process by submitting clean claims, verifying eligibility, coding accurately, using clearinghouse edits, tracking claim status, and following up on unpaid claims.
Use this checklist:
- Verify eligibility before service.
- Confirm prior authorization.
- Use accurate CPT, ICD-10-CM, HCPCS, and modifiers.
- Submit claims electronically.
- Review clearinghouse rejections daily.
- Apply payer-specific edits.
- Track accepted, rejected, pending, paid, and denied claims.
- Post ERA and EOB data accurately.
- Appeal denied claims on time.
- Follow unpaid claims through AR follow-up.
