Medical Billing Software Medical Billing General 4 — Questions and Answers
Question 1: What is the purpose of the National Provider Identifier (NPI) in medical billing?
- To identify each patient uniquely across all payers
- To assign a unique 10-digit number to health care providers for standard transactions (Correct answer)
- To track controlled substance prescriptions nationally
- To certify that a provider has passed credentialing requirements
Correct answer: To assign a unique 10-digit number to health care providers for standard transactions
The NPI is a HIPAA-mandated unique 10-digit identifier for covered health care providers used in all standard electronic transactions.
Question 2: A claim is rejected at the clearinghouse before reaching the payer. What is the most likely reason?
- The diagnosis code is not medically necessary
- The claim contains a formatting or data error that fails HIPAA transaction standards (Correct answer)
- The patient's deductible has not been met
- The procedure requires prior authorization
Correct answer: The claim contains a formatting or data error that fails HIPAA transaction standards
Clearinghouses validate claims against HIPAA transaction standards, and rejections at this stage are typically due to missing or improperly formatted data elements.
Question 3: Which of the following best describes 'unbundling' in medical billing?
- Combining multiple small claims into one submission
- Billing component codes separately when a comprehensive code should cover all services (Correct answer)
- Packaging lab and office visit charges on one claim
- Splitting a facility fee from a professional fee
Correct answer: Billing component codes separately when a comprehensive code should cover all services
Unbundling is the improper practice of billing individual component codes separately to receive higher reimbursement when a single comprehensive code applies.
Question 4: What does 'credentialing' refer to in a medical billing context?
- Training billing staff on new software features
- The process of verifying a provider's qualifications to participate in an insurance network (Correct answer)
- Obtaining prior authorization for a procedure
- Setting up electronic fund transfers with a payer
Correct answer: The process of verifying a provider's qualifications to participate in an insurance network
Credentialing is the formal process by which payers verify a provider's education, licensure, and experience before granting network participation and billing privileges.
Question 5: When a payer applies a contractual adjustment to a claim, which financial term describes the amount written off?
- Coinsurance
- Contractual allowance (Correct answer)
- Bad debt
- Patient responsibility
Correct answer: Contractual allowance
A contractual allowance is the difference between the provider's billed charge and the payer's contracted rate, which is written off and not billed to the patient.
Question 6: In ICD-10-CM, which code would be used to report a subsequent encounter for a condition?
- The same code with a 'D' 7th character (Correct answer)
- A Z code for aftercare
- A new primary diagnosis code
- The same code with an 'A' 7th character
Correct answer: The same code with a 'D' 7th character
The 7th character 'D' in ICD-10-CM injury codes designates a subsequent encounter, meaning the patient is receiving active treatment after the initial visit.
Question 7: What is the function of the Correct Coding Initiative (CCI) edits maintained by CMS?
- To update CPT codes annually for new procedures
- To prevent improper payment of procedure code combinations that should not be billed together (Correct answer)
- To set Medicare fee schedule amounts for each service
- To define medical necessity criteria for coverage decisions
Correct answer: To prevent improper payment of procedure code combinations that should not be billed together
CCI edits are pairs of CPT codes that Medicare considers mutually exclusive or bundled, preventing simultaneous billing of both codes in most circumstances.
