AAPC CPB Sample Questions:

01. A claim for a dependent spouse is rejected electronically with the message: “Subscriber relationship invalid.” The registration record lists the patient as the subscriber, but the insurance card shows the patient’s spouse as the policyholder. Which correction is most appropriate?
a) Remove the spouse’s name from the claim because only the patient receiving care should be listed
b) Update the subscriber information to identify the spouse as the policyholder and the patient as dependent spouse
c) Convert the account to self-pay because electronic rejections cannot be corrected
d) Change the patient relationship to child because dependent claims are always submitted that way

02. A Medicare patient is scheduled with a nurse practitioner for follow-up of controlled hypertension under an existing physician plan. During the visit, the patient reports new chest discomfort. The nurse practitioner evaluates the new complaint, orders an ECG, and changes the treatment plan. The office wants to bill the entire visit incident-to the physician. Which billing interpretation is most appropriate?
a) Incident-to billing is appropriate because the appointment was originally scheduled as a follow-up
b) The service should be billed under the physician even if the physician was not involved and requirements were not met
c) Incident-to billing is required because an ECG was ordered
d) The new problem and changed treatment plan may prevent incident-to billing for the visit under the physician

03. A patient recently married and is added to a spouse’s commercial insurance plan. The eligibility response for the spouse’s plan rejects because the patient’s last name in the practice management system does not match the payer record. The patient provides a current insurance card and legal name-change documentation. What is the most appropriate billing-office action?
a) Submit the claim using the patient’s former name because the medical record was originally created that way
b) Remove the spouse’s plan and bill the patient as self-pay because name changes cannot be corrected
c) Update the patient demographic and subscriber relationship information according to verified documentation before resubmitting
d) Change the patient relationship to subscriber even though the spouse is the policyholder

04. A physician performs a procedure in an ambulatory surgical center. The professional claim is submitted with the place of service listed as office. The commercial payer pays the claim at a higher nonfacility rate. During audit review, the payer requests repayment based on incorrect place-of-service reporting. Which billing-office response is most appropriate?
a) Keep the office place of service because it produces higher reimbursement
b) Change the medical record to show the procedure occurred in the office
c) Submit a second claim using the ambulatory surgical center place of service while keeping the original payment
d) Correct the claim to report the ambulatory surgical center place of service and address any overpayment according to payer policy

05. A retired military beneficiary is enrolled in Medicare Part A and Part B and also has TRICARE for Life. The patient receives a covered physician office service. Which payer order should the billing specialist generally expect?
a) TRICARE for Life generally processes after Medicare for Medicare-covered services
b) TRICARE for Life always pays first because military benefits override Medicare
c) Medicaid must process before both Medicare and TRICARE for Life
d) The patient must be billed first because TRICARE for Life does not coordinate with Medicare

06. Refer to the claim rejection excerpt below.
Source document excerpt:
- Service: In-office laboratory test performed by the practice.
- Payer rejection: “CLIA number required for laboratory service.”
- Practice record: Valid CLIA certificate is on file.
- Claim submitted: CLIA field blank.
What is the best corrective action?
a) Add the physician’s National Provider Identifier in the CLIA field
b) Bill the patient because the payer rejected the laboratory claim
c) Add the valid CLIA number to the claim and resubmit according to payer instructions
d) Remove the laboratory test from the claim because CLIA-related rejections cannot be corrected

07. Refer to the payer policy and operative report excerpt below.
Source document excerpt:
- Payer policy: “Assistant surgeon services are payable only when the procedure allows assistant surgeon reimbursement and the operative report documents the assistant’s specific role and medical necessity.”
- Operative report: “Dr. Patel assisted.” No further details describe the assistant’s role or why assistance was medically necessary.
- Claim submitted: Assistant surgeon modifier appended.
What is the most appropriate billing interpretation?
a) The assistant surgeon modifier should be replaced with a diagnosis code
b) The assistant surgeon claim may deny because the operative report does not document the assistant’s specific role or medical necessity
c) The assistant surgeon claim must be paid because any mention of assistance is sufficient
d) The billing specialist should add details about the assistant’s role before submitting records

08. Eligibility verification shows a patient has Medicaid coverage with a monthly share-of-cost amount that has not yet been met. The patient is scheduled for a covered office service. Which billing interpretation is most appropriate?
a) The office should remove Medicaid from the account because share-of-cost coverage is not real coverage
b) Medicaid will automatically pay the full claim because the patient is eligible
c) The service must be billed to Medicare because Medicaid share-of-cost patients cannot use Medicaid
d) The patient may be responsible for charges until the share-of-cost requirement is met according to Medicaid rules

09. A patient has an active payment plan for a $500 balance from a surgery claim. A later payer reprocessing on a separate visit creates a $75 patient credit. The practice policy allows credits to be applied to another balance only with patient authorization or if permitted by the signed financial agreement. No such authorization is documented. What should the billing specialist do?
a) Follow policy by obtaining authorization or reviewing the signed agreement before applying the credit to the payment-plan balance
b) Apply the credit automatically because all balances belong to the same patient
c) Send the credit to the surgeon personally because the surgery account has a balance
d) Delete the credit because the patient still owes money on another visit

10. A billing specialist needs to send an appeal packet containing a patient’s name, member ID, diagnosis codes, operative note, and remittance advice to a payer. A coworker suggests using the specialist’s personal email account because the work email system is temporarily slow. Which action is most appropriate?
a) Post the documents to a shared public folder and send the payer the link
b) Remove only the patient’s name and send the rest through personal email
c) Use an approved secure transmission method according to practice policy rather than a personal email account
d) Use personal email because the payer needs the information quickly
