25 questions on the CPT 10000 series — lesion excision and destruction, wound repair, adjacent tissue transfer, skin grafts, biopsy, Mohs, nails, incision and drainage, burns and breast procedures. Most are full vignettes where you pick the code. Free, untimed, with a worked explanation for every answer.

The Integumentary System is the first surgery subsection in CPT, and for most candidates it is the first place the exam stops being about vocabulary. Almost every code in the 10000 series is chosen by a measurement, a depth, a count or an anatomic grouping, and the groupings are not the same from one family to the next. That is what makes the chapter feel harder than it reads.
So this quiz is built as vignettes. Nineteen of the twenty-five questions give you a short synthetic operative note and ask for the code, the same shape as the real exam. The remaining six test the bundling rules that decide whether a second code is reported at all.
Three different rules govern three families that look similar on the page:
Twelve sub-topics, weighted towards the areas that produce the most errors:
The anatomic groupings are written into the code descriptors, and they change between classifications. Hands and feet sit with the trunk and extremities for simple repair, but move into the neck grouping for intermediate repair. The scalp travels with the trunk for intermediate repair but with the arms and legs for complex repair. There is no shortcut here: read the grouping in the descriptor you are about to report, every time.
Every question carries a worked explanation that says why the wrong options are wrong, not just why the right one is right. A correct answer reached by elimination is worth revisiting — on the real exam the same measurement rule will appear with different distractors, and elimination will not be available.
The sub-topic breakdown on your score card is the useful output. A sub-topic below seventy per cent is a reading assignment, not a reason to retake the quiz immediately. Read the relevant CPT guidelines, leave it a few days, then come back.
Note on sources: code descriptors, guideline text and parenthetical instructions are as published by the AMA in the current CPT Professional edition. Always verify against your own current-year manual — the exam is taken with the edition in effect on your test date.

Yes. All 25 questions, the sub-topic score breakdown and the worked explanation for every answer are free, with no sign-up and no payment.
Take the greatest clinical diameter of the lesion and add the narrowest margin, counted on both sides. Measure before the excision: a specimen shrinks once removed and fixed, so sizing from the pathology report will push you into a lower code tier.
A simple, single-layer closure is included in the excision and is not reported again. An intermediate or complex repair is reported separately. If the defect is closed by adjacent tissue transfer instead, the flap code already includes the excision, so the excision is not reported at all.
Because CPT writes the groupings into each code descriptor, and they are not consistent across classifications. Hands and feet sit with the trunk and extremities for simple repair but move into the neck grouping for intermediate repair. Read the grouping in the descriptor you are about to report.
Yes. The 25 questions are shuffled on every attempt, so a retake is not a memory test of the same sequence. Your answers are saved in your own browser for 24 hours, so a refresh or a stray back button does not lose them.
