Certified Professional Biller (CPB®) Exam — Questions and Answers

Question 1: Which of the following is a valid reason a payer may apply a 'global period' payment limitation?

The claim was submitted electronically instead of on paper
The patient changed insurance plans during treatment
Post-operative services are considered included in the surgical fee for a set number of days (Correct answer)
The provider's NPI was not registered with the payer

Correct answer: Post-operative services are considered included in the surgical fee for a set number of days

Global surgery packages include pre-operative, intraoperative, and post-operative care within a defined period, so routine follow-up visits are not separately reimbursable.

Question 2: What is geographic practice cost index (GPCI) used for?

Calculating patient deductibles
Adjusting Medicare physician fee schedule payments based on the cost of practicing in different geographic locations (Correct answer)
Determining hospital DRG weights
Setting ambulatory surgery center rates

Correct answer: Adjusting Medicare physician fee schedule payments based on the cost of practicing in different geographic locations

GPCIs adjust the work, practice expense, and malpractice RVU components of the Medicare fee schedule to reflect regional cost differences.

Question 3: Why must documentation be completed promptly after services are rendered?

To maintain accurate records and meet compliance (Correct answer)
To enable relaxed billing processes
To allow unlimited time for corrections
To reduce administrative workload

Correct answer: To maintain accurate records and meet compliance

Documentation must be completed promptly after services are rendered to ensure the accuracy and completeness of the medical record and to meet compliance requirements. Timely documentation reduces the risk of errors or forgotten details, which can impact patient care and billing accuracy. It also ensures that records are available for claim submission and audits, supporting the medical necessity of services provided.

Question 4: When a patient is admitted for chemotherapy and also receives radiation therapy during the same encounter, which condition is sequenced first?

The most severe symptom
The radiation therapy encounter Z code
The neoplasm being treated
The chemotherapy encounter Z code (Correct answer)

Correct answer: The chemotherapy encounter Z code

Per ICD-10-CM guidelines, the encounter for chemotherapy (Z51.11) is the principal diagnosis when it is the reason for the encounter.

Question 5: What is capitation in managed care reimbursement?

Question 34: What is a deductible in an insurance contract?

Total claim amount
Out-of-pocket amount before insurance pays (Correct answer)
Monthly premium
Co-payment

Correct answer: Out-of-pocket amount before insurance pays

A deductible in an insurance contract is the specific amount of money the policyholder must pay out-of-pocket for covered healthcare services before their insurance plan begins to pay. For example, if a policy has a $1,000 deductible, the patient is responsible for the first $1,000 of covered medical expenses each year. Once the deductible is met, the insurance typically starts covering a percentage of subsequent costs.

Question 35: When a claim is submitted with an incorrect billing provider NPI, the most likely outcome is:

The claim will be forwarded to the correct provider automatically
The claim will be paid at a reduced rate
The payer will request a corrected diagnosis code
The claim will be denied or rejected due to enrollment mismatch (Correct answer)

Correct answer: The claim will be denied or rejected due to enrollment mismatch

Valid if the date of service is recorded
Considered incomplete documentation and may be denied (Correct answer)
Payable as long as the diagnosis is correct
Acceptable if the NPI is on the claim

Correct answer: Considered incomplete documentation and may be denied

CMS requires that all documentation be authenticated (signed and dated) by the ordering/treating provider to support medical necessity.

Question 53: What is the primary goal of a denial management process?

To identify, appeal, and prevent claim denials to maximize reimbursement (Correct answer)
To write off all denied claims
To increase patient co-pays
To cancel patient accounts

Correct answer: To identify, appeal, and prevent claim denials to maximize reimbursement

Denial management involves analyzing denial patterns, appealing wrongful denials, and implementing process improvements to reduce future denials.

Verify whether the original claim was already paid or is still pending before resubmitting (Correct answer)
Submit a corrected claim with a different date of service
Immediately bill the patient for the full amount
File a complaint with CMS

Correct answer: Verify whether the original claim was already paid or is still pending before resubmitting

Before resubmitting, the biller should check the payer's records or remittance advice to confirm whether the original claim was paid, pending, or truly a duplicate error.

Question 58: What does 'value-based reimbursement' emphasize compared to fee-for-service?

Faster claim processing
Quality of care and patient outcomes rather than quantity of services (Correct answer)
Lower administrative costs

A clause preventing providers from billing patients
A cap on administrative charges
A penalty for excessive coding errors

Correct answer: A limit on the financial risk a provider assumes, after which the payer covers additional costs

Stop-loss provisions protect providers (especially under capitation) from catastrophic financial losses by shifting risk back to the payer once a threshold is reached.

Question 63: A payer issues an Explanation of Benefits (EOB) showing 'CO-45.' What does this adjustment reason code mean?

Duplicate claim submitted
Service not covered by plan
Claim submitted after the timely filing deadline
Charges exceed the fee schedule/maximum allowable amount (Correct answer)

Correct answer: Charges exceed the fee schedule/maximum allowable amount

CO-45 indicates the charge exceeds the contracted fee schedule or maximum allowable, and the difference is a contractual write-off.

Accept the denial and write off the balance
Rebill the claim immediately with a new date of submission
Transfer the balance to the patient
Send a reconsideration request with proof that only one claim was submitted (Correct answer)

Correct answer: Send a reconsideration request with proof that only one claim was submitted

The provider should appeal or submit a reconsideration with documentation showing the claim was not duplicated.

Question 71: A compliance program's internal audit function is designed to:

Satisfy HIPAA security rule requirements
Proactively identify and correct billing errors before they become systemic problems (Correct answer)
Generate revenue by catching underpaid claims only
Replace external audits by Medicare contractors

Correct answer: Proactively identify and correct billing errors before they become systemic problems

Question 128: Which documentation is crucial to support medical necessity?

Appointment confirmations
Marketing brochures
Progress notes and physician orders (Correct answer)
Patient satisfaction surveys

Correct answer: Progress notes and physician orders

Progress notes and physician orders are crucial documentation to support medical necessity because they provide a detailed account of the patient's condition, the rationale for services provided, and the physician's treatment plan. These records demonstrate why specific tests, procedures, or treatments were necessary for the patient's diagnosis and care. Without this comprehensive documentation, claims may be denied for lack of medical necessity.

Question 129: What is the primary goal of tracking a practice's denial rate as a key performance indicator (KPI)?

To calculate provider productivity
To determine how many patients have outstanding balances
To track the number of new patients seen each month
