Source-backed answer review

The free daily NHA CBCS set includes crawlable question text, answer choices, correct answer labels, objective mapping, and source links. Only the first SEO card includes answer explanations and any extra learning features. Pro-only bank questions stay locked; this section mirrors only the 10 free daily questions already shown on this page.

Question 1 An operative report clearly documents the procedure performed, approach, and relevant anatomical site. A separate nursing note says only that the patient 'tolerated the procedure well.' The coder has enough information to assign the procedure code. What should the coder do?

Answer choices

  1. A. Code from the operative report and relevant documentation; do not query for details that do not affect code assignment.
  2. B. Hold coding until the provider documents additional postoperative tolerance findings, even though the operative report already contains the elements needed for code assignment.
  3. C. Change the procedure code based on the nursing statement.
  4. D. Omit the procedure because the nursing note lacks a full postoperative assessment.

Correct answer

Code from the operative report and relevant documentation; do not query for details that do not affect code assignment.

CBCS abstraction focuses on information relevant to coding, and provider queries are used when clarification is needed. Unnecessary queries for details that do not affect code selection reduce realism and item quality.

Wrong-answer review

  • B. Hold coding until the provider documents additional postoperative tolerance findings, even though the operative report already contains the elements needed for code assignment.: This goes beyond or around the provider documentation instead of reporting only the facts the record supports.
  • C. Change the procedure code based on the nursing statement.: The nursing note does not contradict the documented procedure and does not provide a basis to change the code.
  • D. Omit the procedure because the nursing note lacks a full postoperative assessment.: The code is supported by the operative documentation; unrelated missing detail does not erase the performed service.

Extra learning features

Why candidates miss this

The distractor ‘Hold coding until the provider documents additional postoperative tolerance findings, even though the operative report already contains the elements needed for code assignment’ is appealing because it suggests a more thorough investigation. However, it’s unnecessary and potentially wasteful, as the operative report already provides the required information. The decisive clue is the emphasis on abstracting *required* information, which means focusing on what’s already present and relevant. Likely wrong answer: Hold coding until the provider documents additional postoperative tolerance findings, even though the operative report already contains the elements needed for code assignment.

Question 2 A practice finds that registration errors are repeatedly creating invalid member IDs on claims that later reject at the clearinghouse. What revenue-cycle improvement best addresses the upstream cause?

Answer choices

  1. A. Add denial-management staff to rework the rejected claims faster while leaving the upstream registration or claim-validation defect unchanged.
  2. B. Submit claims faster so the payer sees the error sooner.

  4. D. Strengthen insurance verification at registration and add a pre-transmission validation control for member identifiers.

Correct answer

Strengthen insurance verification at registration and add a pre-transmission validation control for member identifiers.

  2. B. Request a secondary review of the claim by the payer’s medical review department.

Question 5 A patient has both a primary insurance plan and a secondary insurance plan. The primary plan’s coverage has expired, but the secondary plan continues to cover the patient’s services.

Answer choices

  1. A. Confirm the current coverage status and coordination information with both payers before submitting the claim
  2. B. Utilize the birthday rule to determine the primary payer’s coverage period
  3. C. Immediately bill the primary plan, as it was the initial coverage

Question 6 A payer asks the billing office to confirm information needed to adjudicate a claim. The request is for payment activity and comes through the payer’s verified channel. Which HIPAA principle applies?

Answer choices

  1. A. No PHI may be disclosed to a payer unless the patient signs a new authorization for every claim.
  2. B. Send the full requested record set because the request came through an authenticated channel, rather than limiting the disclosure to the information needed for the stated purpose.
  3. C. The office should change the clinical documentation to match the payer’s request before sending it.
  4. D. The office may disclose PHI permitted for payment, limiting the disclosure to the information reasonably necessary for that payment purpose.

Correct answer

The office may disclose PHI permitted for payment, limiting the disclosure to the information reasonably necessary for that payment purpose.
