- The CCA exam is open book, but you must bring specific approved editions of ICD-10-CM, ICD-10-PCS, and the AMA CPT Professional Edition.
- Handwritten notes inside your code books are permitted; no external reference sheets or printed study guides are allowed.
- With 105 questions and a 120-minute time limit, you have roughly 68 seconds per question-speed in book navigation is non-negotiable.
- Clinical Classification Systems makes up 30-34% of the scored exam; your code books must be tabbed and annotated for ICD-10-CM, ICD-10-PCS, and CPT navigation.
Why Open Book Is Harder Than It Sounds
When candidates first learn the CCA exam is open book, the instinct is relief. Bring your code books, look things up, problem solved. That reaction fades quickly once you do the math. The exam contains 105 multiple-choice questions-90 scored, 15 unscored pretest items-and you have exactly 120 minutes to complete all of them. That works out to roughly 68 seconds per question, including any time you spend flipping through a 900-page ICD-10-CM manual.
Open-book access does not mean unlimited time. It means AHIMA wants to see that you can apply coding guidelines in context, not just memorize code numbers. Questions on the CCA are written to test whether you understand the logic behind a code selection, which means even when the answer is technically "in the book," you still need to know which book, which section, and which guideline to look at-and you need to get there fast.
This article is entirely dedicated to making that process efficient and deliberate. If you want an overview of whether you qualify to sit for the exam in the first place, see our guide on CCA Exam Eligibility Requirements 2026: Can You Apply? before diving into strategy here.
What Books Are Allowed in the Testing Room
AHIMA maintains an approved code book list for each testing window, and Pearson VUE proctors enforce it strictly. For the current testing window, you are permitted to bring:
- One ICD-10-CM code book from the approved list
- One ICD-10-PCS code book from the approved list
- One AMA CPT Professional Edition from the approved list
The edition requirement shifts on a defined schedule. The 2025 code books are required for exams taken through April 30, 2026. Beginning May 1, 2026, you must use 2026 code books. If you are scheduling your exam close to that transition date, verify your eligibility window carefully. Your 120-day window to schedule begins when AHIMA approves your application, so a late-spring application could land you in the 2026 book cycle.
What is not allowed: printed study guides, external reference sheets, loose pages, sticky notes attached to the outside of your books, or any digital device. The only external material permitted is what is physically bound into your approved code books-plus anything you have written directly on the pages.
Approved Book Checklist
Before test day, confirm all three of the following are in order:
- ICD-10-CM book is on AHIMA's approved list for your testing window
- ICD-10-PCS book is on AHIMA's approved list (separate volume or combined edition as approved)
- AMA CPT Professional Edition-not the Standard Edition-is the correct year
- All books are the correct year for your testing date (pre or post May 1, 2026)
- No loose inserts, stapled pages, or unapproved laminated cards inside the books
Anatomy of a CCA Question and What It Demands from Your Books
The CCA uses 105 multiple-choice questions. Understanding the structure of these questions tells you exactly how to use your books under time pressure.
Questions That Require Direct Code Lookup
Some questions present a clinical scenario-a diagnosis, a procedure, a setting-and ask you to identify the correct code or code range. These are the questions where your book navigation speed matters most. A typical scenario might describe a patient encounter with a specific diagnosis and ask which ICD-10-CM code applies. Your job is to locate the Alphabetic Index entry, verify in the Tabular List, and apply any instructional notes-all within about a minute.
Questions That Require Guideline Recall
A significant portion of questions test your knowledge of official coding guidelines rather than a specific code. These might ask about sequencing rules, combination code logic, or when to use an additional code. For these questions, your book is a confirmation tool, not a search tool. You should be able to answer from knowledge and then verify quickly if uncertain. The ICD-10-CM Official Guidelines for Coding and Reporting-published inside most approved ICD-10-CM books-is one of the most important sections to annotate.
Questions Tied to Specific CCA Domains
The exam's six domains are not evenly weighted, and that imbalance should shape how you use your books. Domain 1: Clinical Classification Systems carries 30-34% of the exam-the largest single block. This domain covers ICD-10-CM diagnosis coding, ICD-10-PCS procedure coding, and CPT/HCPCS coding. It is also the domain most directly served by your open-book access. Domain 2 (Reimbursement Methodologies, 15-19%) and Domain 3 (Health Records and Data Content, 16-20%) involve conceptual knowledge where books help less than you might expect.
Tabbing Your Books by CCA Domain
Tabbing is the single most impactful preparation step for the open-book format. Done correctly, it turns a 900-page reference into a rapid-navigation tool. Done poorly-or not at all-and you lose minutes hunting for sections you could have located instantly.
ICD-10-CM: Priority Tabs
Place durable, labeled tabs at a minimum on these sections:
- Official Guidelines for Coding and Reporting - this is your most-referenced section for guideline questions
- Alphabetic Index to Diseases and Injuries - start of the Index
- Tabular List, Chapter 1 - start of the Tabular (A00)
- Table of Neoplasms - a frequent lookup target for Domain 1 cancer coding questions
- Table of Drugs and Chemicals - essential for poisoning and adverse effect questions
- External Cause of Injuries Index
- High-frequency chapters: Chapter 19 (Injury/Poisoning, S and T codes) and Chapter 21 (Z codes, factors influencing health status)
ICD-10-PCS: Priority Tabs
- ICD-10-PCS Official Guidelines
- Alphabetic Index
- Tables Section 0 (Medical and Surgical) - the largest and most tested section
- Root operation definitions - critical for understanding PCS structure questions
CPT Professional Edition: Priority Tabs
- E/M guidelines (2021 guidelines are fully in effect; know where they appear in your edition)
- Surgery section start
- Radiology, Pathology/Lab, Medicine sections
- Appendix A (Modifiers) - modifier questions appear across multiple domains
- Category II and III codes start tabs
What to Handwrite in Your Code Books
AHIMA explicitly permits handwritten notes inside your code books. This is one of the most underutilized advantages available to CCA candidates. The rule is that notes must be handwritten directly in the book-not on separate paper placed inside, not on printed sheets tucked between pages.
High-Value Annotations for the CCA
Focus your annotations on information you find yourself consistently forgetting or that requires multi-step reasoning to reconstruct under pressure. Strong candidates typically annotate:
- Sequencing reminders in the ICD-10-CM Tabular where "Code first" and "Use additional code" notes appear-write a brief plain-English summary of when each applies
- PCS root operation decision trees sketched into the margins of the Guidelines section-even a simple flowchart of three or four root operations saves significant thinking time
- CPT modifier quick reference written into Appendix A margins-modifiers 25, 51, 59, and 91 are particularly common in coding scenarios
- DRG and APC reminders near ICD-10-PCS and CPT sections respectively-Domain 2 (Reimbursement Methodologies) questions often connect code selection to payment methodology, and a brief note like "MS-DRG = inpatient" can anchor your reasoning
- Chapter-specific guideline summaries at the top of high-frequency Tabular chapters (e.g., a three-line note at Chapter 19 about sequencing injury codes with seventh-character requirements)
Do not annotate everything. Annotating too heavily creates visual noise. Prioritize the concepts that cost you points in CCA practice tests and write only what genuinely helps.
Balancing Speed and Accuracy in a 120-Minute Window
With 105 questions and 120 minutes, a useful mental model is to budget 60 seconds per question and use the remaining 15 minutes for review. That means any question requiring a full code lookup-from Alphabetic Index through Tabular confirmation-needs to complete within 60 seconds. That is achievable, but only if you have practiced the motion until it is nearly automatic.
| Question Type | Typical Time Budget | Book Use |
|---|---|---|
| Guideline/rule recall | 20-35 seconds | Confirm only; already know the answer |
| Single-code lookup (ICD-10-CM or CPT) | 45-60 seconds | Index → Tabular/code descriptor; verify |
| Multi-code sequencing scenario | 60-90 seconds | Index + Guidelines; may need both books |
| ICD-10-PCS table lookup | 60-75 seconds | PCS Index → Table; verify all 7 characters |
| Reimbursement/compliance conceptual | 30-45 seconds | Minimal to none; knowledge-based |
Notice that Domain 2 (Reimbursement) and Domains 4-6 (Compliance, IT, Confidentiality/Privacy) are primarily knowledge-based. Your books give you little advantage there. This means your open-book strategy should save time on Domain 1 questions-where lookups are fast and confident-so you can spend slightly more time on conceptual questions in other domains without falling behind on pace.
Domain-by-Domain Lookup Strategy
Domain 1: Clinical Classification Systems (30-34%)
This is where your books earn their weight. ICD-10-CM, ICD-10-PCS, and CPT questions dominate this domain. Master the Index-to-Tabular workflow until it is reflexive.
- Always verify in the Tabular-never code from the Index alone
- For PCS, read all seven characters from the table; a wrong character anywhere invalidates the code
- For CPT E/M, know the 2021 MDM and time-based selection framework cold; CPT guidelines are inside your book
- Neoplasm and drug/chemical table questions are high-frequency-know exactly where those tables are tabbed
Domain 2: Reimbursement Methodologies (15-19%)
Questions here connect code selection to payment systems-MS-DRGs for inpatient, APCs for outpatient, RVUs for physician payment. Your code books have limited use here. Annotations near relevant code sections can serve as memory prompts, but the underlying knowledge must be internalized.
- Know which classification system feeds which payment methodology
- Understand how a principal diagnosis affects DRG assignment conceptually
- Annotate a brief "MS-DRG = inpatient / APC = outpatient HOPD" reminder at the start of your ICD-10-PCS Guidelines section
Domain 3: Health Records and Data Content (16-20%)
This domain covers documentation standards, health record components, and data quality. Code books offer essentially no lookup value here. Budget your time accordingly-these questions should be among your fastest.
Domains 4, 5, and 6: Compliance, IT, Confidentiality/Privacy (5-9% each)
These three domains each represent a smaller slice of the exam. HIPAA, compliance program elements, and health information technology concepts appear here. None of these are meaningfully supported by code book lookups. Treat them as pure knowledge questions and move quickly.
How to Practice Open-Book Technique Before Test Day
The most common mistake candidates make is studying content in isolation and only opening their code books when genuinely stumped. That approach trains the wrong skill. You need to practice the full motion: read a question, decide which book and which section, navigate there, confirm the answer, and move on.
A Focused Four-Week Pre-Exam Drill Plan
Build Your Book Infrastructure
- Tab all three code books using the priority sections listed above
- Write foundational annotations: sequencing rules, PCS root operation notes, CPT modifier summary
- Complete 20 timed ICD-10-CM diagnosis coding questions using only your book; track seconds per question
Domain 1 Speed Drilling
- Focus on ICD-10-PCS table navigation-build muscle memory for reading seven-character tables
- Drill CPT surgery and E/M scenarios; practice locating descriptors in under 45 seconds
- Use timed CCA practice questions to simulate test conditions with books open beside you
Mixed Domain Practice
- Simulate full 60-question timed sessions with books available
- Track which question types cause you to exceed 90 seconds; add annotations in those areas
- Review Domain 2 reimbursement concepts without book reliance-these must be memorized
Full Simulation and Refinement
- Complete at least two full 105-question practice sessions at 120 minutes with books open
- Finalize annotations based on error patterns from Week 3
- Confirm your approved book editions match your test date's requirements
This four-week structure prioritizes Domain 1 first because it is the largest domain and the one most directly served by open-book access. Pairing this drill plan with ongoing CCA practice tests at ccaexamprep.com gives you the repetition needed to make navigation feel automatic rather than effortful.
Key Takeaway
Every minute you spend practicing open-book technique before test day is more valuable than time spent re-reading content you already know. The bottleneck on exam day is navigation speed, not knowledge depth.
Once you have your books tabbed, annotated, and practiced with, make sure your exam registration is squared away. The exam fee is $299 for AHIMA members and $399 for non-members, with retake fees at the same rate-and your 120-day eligibility window starts ticking once AHIMA approves your application. Review the complete CCA Exam Eligibility Requirements for 2026 to confirm your timeline before scheduling.
Frequently Asked Questions
No. Only handwritten notes written directly on the pages of your approved code books are permitted. Sticky notes, loose papers, printed reference sheets, and any material not permanently bound into the book will be confiscated by the Pearson VUE proctor. Write your notes directly on pages or in margins.
Testing through April 30, 2026 requires 2025 code books. Testing from May 1, 2026 onward requires 2026 code books. If your 120-day scheduling window spans that boundary, verify which cycle your actual test date falls into before purchasing books or sitting down at the Pearson VUE center.
AHIMA's approved list specifies the AMA CPT Professional Edition. The Professional Edition includes additional clinical descriptors, coding tips, and the full text of guidelines that the Standard Edition omits. Bring the Professional Edition; do not risk having a non-approved book rejected at check-in.
Domain 1 (Clinical Classification Systems, 30-34% of the exam) is the most directly supported by lookups-specific codes, guidelines, and table navigation. Domains 2 through 6 are largely conceptual and require internalized knowledge. In practical terms, you will use your books actively on roughly a third of questions and use them only to confirm on another portion. Knowing this distribution helps you allocate preparation time correctly.
Questions left unanswered count against you the same as wrong answers-there is no partial credit for unattempted items. The 120-minute time limit is firm with no scheduled breaks. If you need to leave the room during testing, the clock continues running. Practice pacing with full-length timed sessions before test day so 120 minutes feels like a familiar constraint rather than a surprise.
