2. Insurance Verification: Ensuring Eligibility in the Workflow

Insurance verification confirms whether a patient’s health plan covers the services they will receive. Failure to verify can result in denied claims or unexpected patient costs.

Insurance Verification Process

Real-Time Eligibility Checks: Verifies coverage using automated verification tools.
Coverage Details: Confirms deductibles, copays, coinsurance, and policy limitations.
Network Status: Identifies if the provider is in-network or out-of-network.
Pre-existing Conditions & Exclusions: Ensures the procedure is covered.

Common Issues in Insurance Verification

Issue	Impact	Solution
Expired Insurance	Claim rejection	Verify insurance before the visit
Incorrect Policy Details	Delayed reimbursement	Cross-check patient-provided info
Out-of-Network Provider	Higher patient costs	Notify patients in advance

3. Pre-Authorization: Avoiding Denials in the Medical Billing Process

Specific procedures require prior authorization before they can be performed. This step ensures that the insurance company agrees to cover the service.

When is Pre-Authorization Required?

Advanced Diagnostics: MRI, CT scans, PET scans
Surgical Procedures: Both inpatient and outpatient surgeries
Specialist Care: Referrals under managed care plans (e.g., HMOs)
Specialty Medications: High-cost or non-formulary drugs

Pre-Authorization Workflow

Submit a Request: Provider sends diagnosis, procedure codes, and medical necessity documentation.
Payer Review: The insurance company evaluates the request based on coverage policies.
Approval or Denial: If denied, the provider can submit an appeal with additional documentation.

How to Reduce Pre-Authorization Delays

Use electronic prior authorization (ePA) tools.
Verify requirements for each payer.
Submit complete and accurate documentation.

Medical Billing Process Post-Visit: Steps include charge entry, claim submission (EDI vs. paper), payer adjudication, payment posting, and A/R follow-up for outstanding accounts. — A step-by-step guide to the medical billing process after a patient visit, covering charge entry, claim submission, denial management, payment posting, and accounts receivable follow-up.

Phase 2: Medical Billing Workflow During the Patient Visit

The medical billing process continues during the patient visit. Accurate documentation and coding are crucial for claim approval and timely reimbursement. Mistakes at this stage can result in claim denials, compliance issues, and lost revenue.

4. Clinical Documentation: Backbone of the Medical Billing Process

Clinical documentation records patient visits, diagnoses, and treatments. Thus forming the basis for accurate coding and successful claims.

Key Components of Clinical Documentation

EHR Integration: Provides instant access to patient data for seamless billing.
SOAP Notes: A structured format (Subjective, Objective, Assessment, Plan) for precise documentation.
Avoiding Gaps: Incomplete or unclear details can lead to claim denials.

Best Practices for Error-Free Documentation

Use EHR Templates: Reduces manual errors and improves consistency.
Document Thoroughly: Include all diagnoses, procedures, and provider notes.
Maintain Compliance: Follow CMS and HIPAA rules to prevent audits and penalties.

5. Medical Coding: The Heart of the Billing Workflow

Medical coding converts clinical notes into standardized codes for accurate billing and insurance claims.

Key Coding Systems

System	Purpose	Example
ICD-10-CM	Diagnoses	Diabetes: E11.9
CPT	Procedures	Office visit: 99213
HCPCS Level II	Supplies, drugs, & non-MD services	Ambulance transport: `A0425`

Avoiding Costly Coding Errors

Upcoding (Billing for a higher service than provided) → Risk: Fraud fines.
Downcoding (Billing for a lower service) → Risk: Lost revenue.
Unbundling (Splitting bundled services) → Risk: Denied claims.

✅ Solution: Regular coding audits, AI-powered coding tools, and ongoing staff training.

6. Superbill Creation: Bridging Care and the Billing Process

A superbill is a detailed invoice that captures all services provided during a patient visit. It serves as the foundation for claim generation.

Key Components of a Superbill

Provider Info: Name, NPI number, specialty
Patient Details: Name, DOB, insurance ID
Services Rendered: ICD-10/CPT codes (with modifiers)
Validation Requirements: Service date & provider signature

Why Superbills Matter

Minimizes coding mistakes and claim disputes
Guarantees proper reimbursement matching documentation
Bridges clinical care and revenue cycle efficiency

Phase 3: Post-Visit Medical Billing Workflow

The post-visit phase ensures that claims are processed correctly, payments are received, and outstanding balances are managed efficiently. A structured approach to claim scrubbing, submission, adjudication, and payment posting prevents revenue loss and compliance issues.

7. Charge Entry & Claim Scrubbing: Streamlining the Billing Process

Charge Entry converts medical services into billable claims, while Claim Scrubbing detects and corrects errors before submission.

Key Steps in Charge Entry

Assign ICD-10, CPT, and HCPCS codes based on documentation.
Apply modifiers when needed for precise billing.
Verify units of service to ensure accurate charges.

Claim Scrubbing: Catching Errors Early

Automated scrubbers flag issues like:

NPI/Taxonomy Errors (Wrong provider details)
Coding Mistakes (Upcoding, down coding, or missing codes)
Payer-Specific Rule Violations (Insurers have unique requirements)

✅ Best Practice: Use AI-powered claim scrubbers + manual audits before submission.

8. Claim Submission: Electronic (EDI) vs. Paper in the Workflow

Once the claim is scrubbed, it is submitted to the payer via electronic data interchange (EDI) or paper forms.

Claim Submission Methods

Submission Type	Use Case	Forms Used
Electronic (EDI)	Faster processing, lower rejection rates	837P (Professional) / 837I (Institutional)
Paper Submission	Used if payers don’t accept EDI	CMS-1500 (Physicians) / UB-04 (Hospitals)

✅ Tip: Most payers prefer EDI for faster reimbursements and fewer errors.

For a complete breakdown of modern submission methods, see our Medical Claims Processing Guide covering everything from clearinghouses to direct payer APIs.

9. Payer Adjudication: Decoding the Medical Billing Process

Payers review submitted claims through adjudication, where they approve, deny, or adjust payments.

Key Steps in Payer Adjudication

1. Initial Review: Checks for eligibility, correct coding, and service necessity.

2. Claim Decision:

Accepted: Approved for payment.
Denied: Requires correction and resubmission.
Reduced Payment: Adjusted based on policy coverage.

3. Explanation of Benefits (EOB) or Electronic Remittance Advice (ERA): Details claim decisions.

Common Claim Denial Reasons

Missing Modifiers – Required procedure details not included
Lack of Medical Necessity – Service not covered under policy guidelines
Duplicate Claims – The same claim submitted multiple times

✅ Solution: Implement denial management strategies to appeal and correct errors.

Payers may deny AOB claims if the agreement isn’t properly documented. Learn how to avoid this in our AOB Legal Insights guide.

10. Payment Posting: Finalizing the Workflow

Once adjudication is complete, payments are posted to patient accounts and financial records.

Steps in Payment Posting

ERA/EOB Reconciliation: Matches payer payments with billed charges.
Patient Statements: Sends bills for any remaining balance.
Adjustments & Write-Offs: Handles contractual reductions or uncollectible amounts.

✅ Tip: Automate payment posting to improve cash flow and financial accuracy.

11. A/R Follow-Up: Closing Gaps in the Medical Billing Process

Accounts Receivable (A/R) follow-up ensures outstanding balances are collected efficiently.

A/R Management Best Practices

Aging Reports: Track unpaid claims over 30, 60, and 90+ days.
Ethical Collections: Offer payment plans, financial counseling, and digital payment options.
Bad Debt Management: Write off balances when collections are no longer feasible.

✅ Strategy: Use automated A/R tracking and proactive patient communication to reduce outstanding balances.

Key strategies include:
1. Verifying insurance eligibility in real-time,
2. Using automated claim scrubbers to reduce errors,
3. Training staff on compliance updates,
4. Tracking and analyzing denial patterns,
5. Integrating EHRs, AI tools, and patient payment portals for efficiency.
6. Regular audits and performance reviews ensure sustained improvements.

What are the 10 steps in the medical billing process?

1. Patient registration (collecting demographics/insurance).
2. Insurance verification (confirming coverage).
3. Pre-authorization (for specific services).
4. Clinical documentation (recording diagnoses/treatments).
5. Medical coding (assigning ICD-10, CPT, or HCPCS codes).
6. Charge entry (linking codes to billing systems).
7. Claim scrubbing (error-checking before submission).
8. Claim submission (sending to payers electronically/paper).
9. Payer adjudication (insurer’s approval/denial).
10. Payment posting & A/R follow-up (reconciling payments/appealing denials).
