AAPC free flashcards
8 real CPC flashcards, sampled across every domain the exam tests. Each concept card is paired with the misconception card built from the tempting wrong answer - the trap most decks skip. No account, no card.

When one surgeon performs several distinct procedures in a single session, which procedure gets modifier 51 appended?
The highest-valued procedure is billed at full value, and each lesser procedure carries modifier 51. This triggers the multiple-procedure payment reduction, rather than signalling a bundling exception.
Append modifier 51 to the higher-valued primary procedure to flag the multiple-procedure relationship.
Modifier 51 signals a secondary procedure, but the primary is the higher-valued service and stays unmodified; placing 51 on the primary reverses the intended sequencing.
How is a vaccine reported when given without physician counselling?
Report two codes: the product code for the substance supplied plus an administration code from the 90471 series for the act of injecting it. Neither code alone captures the full service.
Can 90460 report the injection of an adult's flu vaccine?
No. 90460 applies only to patients through 18 years when the physician counsels, so it is wrong for a 45-year-old without counselling. Use the 90471 series instead.
How are units determined for a J-code drug such as ondansetron J2405 defined per 1 mg?
HCPCS Level II drug codes carry a dosage in the descriptor, so units equal the documented dose divided by that per-unit amount. A 4 mg dose over a per 1 mg code yields 4 units.
One administration of a per 1 mg drug equals one unit of service.
This treats one administration as one unit, ignoring that the descriptor bills per 1 mg; a 4 mg dose is under-reported and the claim is paid for a quarter of the drug given.
Which two structures form the gastro-oesophageal junction?
The combining form gastro- refers to the stomach and oesophageal to the oesophagus, so the gastro-oesophageal junction is where the distal oesophagus meets the cardiac region of the stomach. This is why reflux and lower-oesophageal strictures localise there.
Is the gastro-oesophageal junction where the proximal oesophagus meets the lower pharynx?
No. That describes the pharyngo-oesophageal junction near the upper oesophageal sphincter, tempting because it is also an oesophageal boundary, but it sits at the neck, not the stomach.
