CPC Cheat Sheet.
The night-before summary, built like the exam.

CPC Exam — At a Glance

• 100 multiple-choice questions
• 4 hours (240 minutes) total testing time
• Passing score: 70%
• Exam fee: $425 (1 attempt)

Pacing Math (must-remember)

• 240 min ÷ 100 questions = ~2.4 minutes per question — your hard budget.
• Do a time check at Q25 (≈60 min used), Q50 (≈120 min), Q75 (≈180 min).
• To pass you need 70 of 100 correct. You can miss up to 30 and still pass.
• Never leave blanks — there is no penalty math that beats a guess; a blank is a guaranteed miss.

Core Code Sets (know cold)

• CPT® — procedures/services. Category I (5-digit), Category II (performance, -F), Category III (emerging tech, -T).
• ICD-10-CM — diagnoses. Code to highest specificity; confirm laterality, episode, and combination codes.
• HCPCS Level II — supplies, drugs, DME, non-physician services (letter + 4 digits).

Modifier Quick Rules

• -25 significant, separately identifiable E/M on same day as a procedure.
• -59 distinct procedural service (use only when no more specific X{EPSU} modifier fits).
• -26 professional component; -TC technical component.
• -50 bilateral procedure; -51 multiple procedures; -76/-77 repeat by same/other physician.
• -RT / -LT right/left; -GA/-GY/-GZ ABN/liability (HCPCS).

Coding Workflow (apply to every case)

1. Read the full operative/office note before coding.
2. Diagnosis first (ICD-10-CM): Alphabetic Index → verify in Tabular List → apply all instructional notes (Includes, Excludes1/Excludes2, Code First, Use Additional).
3. Procedure (CPT): find the correct code family, read all section guidelines and parenthetical notes.
4. Append modifiers; confirm medical necessity links Dx ↔ procedure.

Excludes Notes (frequent trap)

• Excludes1 = "NOT coded here" — the two conditions can never be reported together.
• Excludes2 = "not included here" — the condition is separate; both may be coded together if documented.

Test-Day Strategy

• Tab and index your code books — the exam is open-book; speed of lookup wins.
• Eliminate obviously wrong options first, then verify the remaining answer in the book.
• Answer easy questions first; flag and return to time-sinks.
• Guess (never blank) any question you can't finish before time runs out.

The Certified Professional Coder exam rewards candidates who have internalized a small set of hard numbers and then spent their study time on speed rather than trivia. This cheat sheet collects the figures that actually govern exam day — question count, clock, scoring line, fee, code books, and renewal — and the traps that quietly cost people points.

The core numbers

According to AAPC, the CPC exam is 100 multiple-choice questions administered in a 4 hour format — 240 minutes total. AAPC sets the minimum passing score at 70%, which in practice means you must correctly answer at least 70 of the 100 questions. There is no partial credit and no separately scored section you can fail independently: the whole exam is one 100-item pool measured against one line.

The single most useful derived number is your per-question budget. Four hours across 100 questions is 2.4 minutes per question, and that average has to absorb the slow ones — the multi-paragraph operative reports where you are hunting through CPT for the right surgical code. Most candidates who fail run out of clock, not knowledge.

AAPC lists the exam fee at $425 for 1 attempt. That figure matters strategically, not just financially: at $425 a shot, a candidate who is scoring in the low 60s on timed practice is better served by two more weeks of drilling than by an early booking.

The open-book rules — the part people get wrong

The CPC exam is open book, and candidates may reference approved code books during the examination. That sounds generous until you read the constraints. AAPC specifies three code sets in play: CPT, ICD-10-CM, and HCPCS Level II. Those three books are your entire permitted reference library — everything else stays outside the room.

The publisher rule is the classic disqualifier. For CPT, the AMA Professional Edition ONLY is allowed and no other publisher is permitted. Candidates routinely show up with a well-loved third-party CPT that they have annotated for months, and discover at check-in that it is not admissible. ICD-10-CM and HCPCS Level II are more forgiving on publisher, but CPT is not — buy the AMA Professional Edition early and study from that specific book, so your muscle memory for page location transfers to exam day.

How to actually use the open-book allowance

Open book is a speed test disguised as a reference privilege. Because you have roughly 2.4 minutes per question and three books to work across, the winning habit is tabbing and margin notes in the exact copies you will carry in — the guideline pages, the modifier tables, the E/M level tables, the anatomy plates. A book you can navigate in fifteen seconds is worth more than a book you have read twice.

Common traps

• Reading the whole vignette first. On long operative notes, read the question stem and answer choices before the narrative. Half the report is usually irrelevant to the code being asked for.
• Bringing the wrong CPT. AAPC permits the AMA Professional Edition only for CPT — any other publisher is not permitted, and there is no substitute available at the testing site.
• Answer-choice elimination beats code-book hunting. Because every item is multiple choice, comparing the four candidate codes and looking up only the ones that differ is far faster than coding from scratch.
• Leaving blanks. The pass line is 70 correct out of 100 with no penalty structure described for wrong answers, so an unanswered question is a guaranteed zero where a guess is not.
• Under-drilling HCPCS Level II. It is one of the three sanctioned code sets, and candidates who spend all their prep in CPT and ICD-10-CM leave points on the table in a book they barely opened.
• Pacing by section instead of by clock. With 240 minutes and 100 questions, check your position against the 2.4-minute average at the quarter marks rather than trying to feel your way through.

After you pass: keeping the credential

Certification is not a one-time event. AAPC requires 36 CEUs every two years — 36 hours of continuing education on a 2 year renewal cycle. Separately, maintaining a current AAPC membership is required to keep the certification active, so lapsed dues can cost you the credential even if your CEUs are complete.

The practical read: 36 CEUs across 24 months is about 1.5 hours of continuing education per month, which is small enough that it is almost always neglect rather than difficulty that causes a lapse. Log CEUs as you earn them rather than reconstructing them in the final quarter of the cycle.

The one-page summary

• Questions: 100 multiple-choice
• Time: 240 minutes (4 hours) — about 2.4 minutes per question
• Pass line: 70% — at least 70 of 100 correct
• Fee: $425 for one attempt
• Format: Open book, 3 code sets — CPT, ICD-10-CM, HCPCS Level II
• CPT restriction: AMA Professional Edition only
• Maintenance: 36 CEUs every 2 years, plus current AAPC membership

Print those seven lines, tape them inside the cover of your CPT, and spend the rest of your prep on timed full-length runs. The numbers are fixed; your pace is the variable you control.
