Have you ever wondered what happens after a patient walks out of your clinic and you submit their insurance claim?
Insurance claims processing is the backbone of healthcare revenue, yet it remains one of the most complex and error-prone aspects of running a medical practice. From verifying patient eligibility to receiving payment, each step requires precision, compliance, and persistence.
In this comprehensive guide, you’ll learn exactly how insurance claims processing works, the critical steps involved, common challenges providers face, and practical strategies to streamline your claims workflow. Whether you’re a medical billing professional or a healthcare administrator looking to reduce claim denials and speed up reimbursements, this guide will give you the insights you need.
What Is Insurance Claims Processing?
Insurance claims processing is the systematic procedure of submitting, reviewing, and receiving payment for healthcare services from insurance companies. It bridges the gap between the care you provide and the revenue your practice receives.
When a patient receives medical treatment, someone must pay for it. If the patient has insurance, your practice submits a claim to their insurance company detailing the services provided, diagnosis codes, and charges. The insurer then reviews this claim, determines the covered amount based on the patient’s policy, and issues payment accordingly.
This sounds straightforward, but in reality, insurance claims processing involves multiple parties, strict regulations, detailed documentation, and various checkpoints where claims can be delayed or denied.
Key parties involved:
- Healthcare providers (doctors, hospitals, clinics)
- Medical billers and coders
- Clearinghouses (intermediaries that format and transmit claims)
- Insurance payers (commercial insurers, Medicare, Medicaid)
- Patients (responsible for co-pays, deductibles, and non-covered services)
Why Insurance Claims Processing Matters
Efficient insurance claims processing directly impacts your practice’s financial health. Consider these facts:
Financial impact: The average claim denial rate in healthcare ranges from 5% to 25%, with denied claims costing providers approximately $5 million annually in lost revenue.
Cash flow consequences: Delays in claims processing mean delays in payment, which can strain your operating budget and affect your ability to pay staff and suppliers.
Patient satisfaction: Billing errors and insurance issues are among the top complaints patients have about healthcare. Smooth claims processing leads to clearer billing statements and happier patients.
Compliance requirements: Improper claims submission can result in audits, penalties, and even accusations of fraud. Accurate processing protects your practice legally.
For healthcare providers partnering with revenue cycle management experts like ProMantra, optimizing insurance claims processing becomes a strategic advantage rather than an administrative burden.
The Insurance Claims Processing Workflow: Step-by-Step
Understanding each phase of insurance claims processing helps you identify where bottlenecks occur and how to prevent them.
Step 1: Patient Registration and Eligibility Verification
The claims process actually begins before any medical service is rendered.
What happens: During patient registration, your front desk collects essential information including the patient’s insurance details, policy number, group number, and identification. This information must be accurate and current.
Eligibility verification involves checking with the insurance company to confirm:
- The patient’s coverage is active
- The services planned are covered under their policy
- Any pre-authorization requirements
- Co-pay, deductible, and out-of-pocket maximum amounts
Why it matters: According to industry data, 30% of claim denials stem from eligibility and registration errors. Verifying coverage upfront prevents the frustration of denied claims weeks later.
Best practice: Verify eligibility at every visit, not just the first one. Insurance coverage can change monthly due to policy updates, job changes, or lapses in payment.
Step 2: Medical Coding
Once the patient receives care, medical coding translates the clinical documentation into standardized codes.
What happens: Professional medical coders review the provider’s clinical notes and assign appropriate codes:
- ICD-10 codes (International Classification of Diseases): Describe diagnoses and medical conditions
- CPT codes (Current Procedural Terminology): Identify the services, procedures, and treatments provided
- HCPCS codes (Healthcare Common Procedure Coding System): Cover supplies, equipment, and services not in CPT
Why it matters: Accurate coding is absolutely critical. Even a single incorrect digit can result in claim denial, underpayment, or compliance issues. The code must match the documented diagnosis and justify the medical necessity of the service.
Common coding challenges:
- Incomplete clinical documentation
- Using outdated code sets
- Upcoding (using codes for more expensive services) or downcoding (using codes for less expensive services)
- Lack of specificity in diagnosis codes
Best practice: Regular training for coders on the latest code updates and clear communication between providers and coders ensures accuracy.
Step 3: Charge Entry
After coding, the financial side of the claim begins.
What happens: The charges for services are entered into the practice management system or billing software. Each service code receives a corresponding charge based on your fee schedule.
Why it matters: Incorrect charge entry can lead to underbilling (lost revenue) or overbilling (compliance issues and claim rejections). The charges must align with contracted rates for each payer.
Best practice: Implement automated charge capture systems and conduct regular audits to catch discrepancies early.
Step 4: Claims Submission
Now the claim is ready to go to the insurance company.
What happens: Claims are typically submitted electronically through a clearinghouse, which acts as an intermediary between your practice and insurance companies. The clearinghouse:
- Formats the claim according to each payer’s specific requirements
- Performs initial scrubbing to catch obvious errors
- Transmits the claim securely
- Provides confirmation of receipt
Most claims follow the HIPAA-compliant 837 electronic format, though some smaller payers may still accept paper claims via the CMS-1500 form.
Why it matters: Electronic claims process faster (typically 14-21 days) compared to paper claims (30-45 days). Clean claims—those with no errors—have a 95% first-pass acceptance rate.
Best practice: Use clearinghouses that offer robust editing features and real-time claim status tracking.

Step 5: Claims Adjudication
This is where the insurance company evaluates your claim.
What happens: The payer’s automated systems and claims adjusters review the claim through multiple checkpoints:
- Initial processing check: Verifies patient eligibility and coverage
- Automated review: Checks for coding errors, duplicate claims, and medical necessity
- Medical review: For complex or high-cost claims, clinical staff may review supporting documentation
- Pricing: Determines payment based on contracted rates, allowed amounts, and patient responsibility
The payer then makes one of three decisions:
- Approved: Full or partial payment will be issued
- Denied: The claim is rejected and no payment will be made
- Pending: More information is needed before a decision
Why it matters: This is the stage where most claim problems surface. Understanding payer adjudication patterns helps you submit cleaner claims from the start.
Common reasons for denial:
- Services not covered under the patient’s plan
- Lack of prior authorization
- Missing or incorrect information
- Duplicate claim submission
- Services deemed not medically necessary
Step 6: Payment Posting
When the payer approves a claim, they issue payment along with an Explanation of Benefits (EOB) or Electronic Remittance Advice (ERA).
What happens: Your billing team posts the payment to the patient’s account, which includes:
- The amount paid by insurance
- Any adjustments or contractual write-offs
- The remaining patient responsibility (co-insurance, deductible, co-pay)
Why it matters: Accurate payment posting ensures your accounts receivable stays current and helps you track which payers are your best performers in terms of timely payment and reimbursement rates.
Best practice: Reconcile EOBs/ERAs daily and investigate any discrepancies between expected and actual payments immediately.
Step 7: Patient Billing
After insurance payment, any remaining balance becomes the patient’s responsibility.
What happens: Your practice generates a patient statement showing:
- Total charges
- Insurance payments and adjustments
- Patient responsibility amount
- Payment due date and options
Why it matters: Patient collections have become increasingly important as high-deductible health plans grow more common. In fact, patient responsibility now accounts for approximately 30% of provider revenue.
Best practice: Offer multiple payment options (online portals, payment plans, credit cards) and communicate clearly about patient financial responsibilities upfront.
Step 8: Claims Follow-Up and Denial Management
Not all claims sail through smoothly. Some require follow-up, and denied claims need attention.
What happens: Your billing team monitors outstanding claims and takes action on:
- Claims pending beyond normal processing time
- Denied claims that can be appealed
- Underpaid claims requiring adjustment
- Claims requiring additional documentation
The appeal process involves:
- Reviewing the denial reason
- Gathering supporting documentation
- Writing an appeal letter addressing the specific denial reason
- Resubmitting within the payer’s appeal timeframe (typically 30-180 days)
Why it matters: Successfully appealing denied claims can recover 50-65% of initially denied amounts. However, this requires persistence and expertise.
Best practice: Track denial patterns by payer, denial reason, and provider to identify systemic issues that can be corrected upstream.

Common Challenges in Insurance Claims Processing
Even with the best systems, healthcare providers face persistent challenges:
High denial rates: With claim denial rates averaging 5-25%, many practices lose significant revenue simply because they don’t have the resources to appeal every denial effectively.
Changing payer requirements: Insurance companies frequently update their submission guidelines, coverage policies, and documentation requirements, making it difficult for small practices to stay compliant.
Manual processes: Many practices still rely heavily on manual data entry, paper documentation, and phone calls for verification, which increases errors and slows processing.
Insufficient documentation: Providers often document for clinical purposes but miss the specific details payers need to approve claims, leading to unnecessary denials.
Staff turnover and training: Billing and coding require specialized knowledge. High turnover means constant retraining, which impacts claim quality.
Technology gaps: Outdated practice management systems may lack integration with clearinghouses, payers, and other tools needed for efficient processing.
At ProMantra, we’ve helped numerous healthcare providers overcome these challenges through our comprehensive revenue cycle management approach that combines technology, expertise, and dedicated support.
