What Is the Medical Billing Cycle?
The medical billing cycle includes all the administrative and financial steps required to collect payments from patients and insurance companies. It begins before a patient walks into the clinic and ends only when the practice receives all outstanding payments.
A complete billing cycle typically includes 10 steps, each contributing to clean claim submission and timely reimbursement.
The 10 Steps of the Medical Billing Cycle
1. Patient Registration
This step starts even before the appointment.
The front desk collects basic patient information.
Name, date of birth, contact details
Insurance information
Reason for visit
Accurate registration is crucial—any errors here can lead to claim denials later.
2. Insurance Eligibility & Benefits Verification
Once patient details are entered, medical billers verify:
Coverage status
Co-pays, deductibles, co-insurance
Prior authorization requirements
Plan limitations
This step ensures the patient is financially cleared before receiving treatment.
3. Patient Check-In & Check-Out
During check-in:
Insurance cards and IDs are scanned
Patient forms are completed
Co-pays may be collected
During check-out:
Services are recorded
Follow-up appointments are scheduled
Outstanding patient balances may be discusse
4. Medical Coding of Services
The services provided by the healthcare professional are translated into:
ICD-10 codes (diagnoses)
CPT/HCPCS codes (procedures & services)
Accurate coding ensures correct reimbursement and minimizes audit risk.
5. Charge Entry
The coded services are entered into the billing system.
Billers assign:
The correct fees
Provider information
Place of service
Modifiers (if needed)
Charge entry ensures claims reflect the true cost of care.
6. Claim Creation
A claim is generated—either CMS-1500 (for professional services) or UB-04 (for facilities).
This step ensures:
All details are present
Payer rules are followed
Coding is compliant
7. Claim Scrubbing & Submission
Before sending to the payer:
Claims are “scrubbed” using software to catch errors
Missing information is corrected
Formatting guidelines are checked
Clean claims get paid faster and reduce denials.
Once scrubbed, claims are sent:
Directly to the payer
Through a clearinghouse
8. Payer Adjudication
The insurance company reviews the claim and decides:
How much they will pay
What part the patient owes
If any corrections are required
The payer then sends back an ERA/EOB detailing decisions.
9. Payment Posting
Billers post payments into the billing system:
Approved amounts
Adjustments
Patient responsibility
Denials (if any)
Posting ensures accurate financial records and patient billing.
10. Denial Management & Patient Billing
If the payer denies the claim:
Billers investigate why, correct the issue, and resubmit.
If a patient owes a balance:
Statements are sent
Payment plans may be arranged
Follow-ups may be done by the billing team or RCM company
This final step ensures the provider receives all revenue owed.
