1. During the initial processing of a claim, if a payer's system identifies a potential issue that
requires additional information before a payment decision can be made, what is the status
assigned to that claim?
a) Denied
b) Paid
c) Pending
d) Finalized
Answer: c) Pending
Explanation: A "Pending" status indicates that the claim is temporarily on hold. The payer has
identified a need for more information or documentation from the provider or patient before the
adjudication process can be completed and a final determination can be issued.

adjustments, and denials directly to a provider's financial system?
a) HIPAA X12 837
b) HIPAA X12 835

d) Electronic Funds Transfer (EFT)
Answer: b) HIPAA X12 835
Explanation: The HIPAA X12 835 transaction set is the federally mandated standard for the
Electronic Remittance Advice (ERA). It is the electronic version of a payment explanation,
detailing how a claim was adjudicated, including payments, denials, and the reason codes for any
adjustments.
3. A provider receives a payment from an insurer that is less than the billed amount. The
accompanying document shows an adjustment with a group code of "CO." What is the most
accurate interpretation of this code?
a) The patient is responsible for this amount.
b) The adjustment is due to a correction of a prior error.
