- The CCA is open-book: you must bring one ICD-10-CM, one ICD-10-PCS, and one AMA CPT Professional Edition from AHIMA's approved list.
- Code book year depends on your test date - 2025 books through April 30, 2026; 2026 books from May 1, 2026 onward.
- Handwritten notes inside your code books are permitted; no external reference sheets, tabs with outside content, or printed guides.
- The exam is 105 questions in 2 hours - 90 scored, 15 unscored pretest items - with a passing scaled score of 300 on a 100-400 scale.
Why the Open-Book Format Changes Everything
Most professional certification exams are closed-book. The CCA is not. Administered by AHIMA through its Commission on Certification for Health Informatics and Information Management (CCHIIM) and delivered at Pearson VUE test centers, the Certified Coding Associate exam permits - and in fact requires - you to bring physical code books into the testing room. This single feature reshapes how you should think about preparation entirely.
Bringing books does not mean the exam is easy to pass. You are working against a two-hour clock with 105 questions to process. Fifteen of those are unscored pretest items, but you will not know which ones. The 90 scored questions span six domains, and every second you spend flipping pages is a second you are not answering questions. Candidates who arrive with well-organized, heavily annotated books consistently outperform those who arrive with pristine, unused ones.
Understanding exactly which books to bring, how to prepare them, and which exam domains lean on which book is the central skill this article addresses. If you are also building a broader study plan, our CCA practice tests are designed to mirror the question style and domain weighting you will encounter on the actual exam.
The Exact Books You Must Bring
AHIMA maintains an approved code book list that is updated each year. For the 2026 testing cycle, the three book categories you must cover are:
- One ICD-10-CM book - This covers the International Classification of Diseases, 10th Revision, Clinical Modification, used for diagnosis coding across inpatient and outpatient settings.
- One ICD-10-PCS book - The Procedure Coding System volume used specifically for inpatient procedure coding.
- AMA CPT Professional Edition - The Current Procedural Terminology manual published by the American Medical Association, required for outpatient and physician procedure coding.
Publishers whose editions commonly appear on the approved list include AHIMA Press, Optum360, and the AMA itself. Before you purchase or use any book, confirm the specific edition and publisher against the current AHIMA approved list on their website. Using a book that is not on the approved list - even if it contains the correct codes - is grounds for it being confiscated at the testing center.
Why Three Separate Books?
Each book corresponds to a distinct coding system tested on the CCA. ICD-10-CM handles diagnoses. ICD-10-PCS handles inpatient facility procedures. CPT handles outpatient procedures and professional services. Domain 1, Clinical Classification Systems, draws from all three and represents 30-34% of your exam score.
- ICD-10-CM: Diagnosis codes, sequencing rules, combination codes, and Z-codes
- ICD-10-PCS: Seven-character alphanumeric structure, root operations, body system tables
- CPT Professional Edition: Evaluation and management, surgery, radiology, pathology, medicine sections plus Appendices A-N
2025 vs. 2026 Code Books: The Cutoff Rule
AHIMA uses a straightforward date-based rule to determine which code year applies to your exam. Getting this wrong is an expensive mistake - the exam fee is $299 for AHIMA members and $399 for non-members, with retake fees at the same rate.
| Test Date | Required Code Book Year | ICD-10-CM/PCS Edition | CPT Edition |
|---|---|---|---|
| Now through April 30, 2026 | 2025 Code Books | FY2025 ICD-10-CM and ICD-10-PCS | CPT 2025 Professional Edition |
| May 1, 2026 and later | 2026 Code Books | FY2026 ICD-10-CM and ICD-10-PCS | CPT 2026 Professional Edition |
Once you receive your Authorization to Test (ATT) from Pearson VUE, you have a 120-day eligibility window to schedule and sit for the exam. If your window straddles the May 1 cutoff, plan carefully. Arriving with 2025 books when the exam uses 2026 content - or vice versa - means you may be referencing codes that have been added, revised, or deleted. Review the CCA Exam Books 2026 guidance for any updates AHIMA issues closer to the transition date.
What You Can (and Cannot) Write in Your Books
AHIMA explicitly permits handwritten notes inside your approved code books. This is one of the most powerful - and most underused - advantages available to CCA candidates. Here is how to use it strategically:
Permitted Annotations
- Handwritten notes, definitions, and reminders written directly on the pages
- Highlighted text within the books
- Underlining, circling, or color-coding sections
- Page tabs and index tabs (though content on tabs must be your own handwriting, not printed labels from outside sources - confirm current Pearson VUE rules at your specific center)
Not Permitted
- Separate reference sheets, cheat sheets, or printed study materials
- Books that are not on the AHIMA approved list
- Electronic devices, tablets, or e-books as a substitute for physical books
- Any book from the wrong code year for your testing window
Think of your annotation strategy as building a second index inside your books. Coders who write the ICD-10-PCS root operation definitions in the margins of their PCS table section, or note common CPT modifier rules beside the Evaluation and Management guidelines, gain seconds on every applicable question. Over 105 questions, those seconds accumulate into meaningful time savings.
Which Domains Demand Which Books
The CCA exam is organized into six domains. Knowing which book you will reach for under each domain helps you build a navigation instinct before test day.
Domain 1: Clinical Classification Systems (30-34%)
This is the exam's largest domain and the one most directly tied to your code books. Expect questions on ICD-10-CM diagnosis coding conventions, ICD-10-PCS procedure coding logic, and CPT procedure and service coding.
- ICD-10-CM: Official Guidelines for Coding and Reporting, sequencing rules, specificity requirements
- ICD-10-PCS: Seven-character structure, root operations (Excision vs. Resection, Repair vs. Replacement), approach values
- CPT: Section-specific guidelines, E/M leveling logic, surgery package rule, modifier usage
Domain 2: Reimbursement Methodologies (15-19%)
Questions here address how coded data drives payment - MS-DRGs for inpatient, APCs for outpatient, and RBRVS for physician services. Your code books support these questions indirectly; understanding how a principal diagnosis assignment shifts a DRG requires fluency in ICD-10-CM sequencing rules.
- Understand how DRG grouping logic depends on MCC and CC codes
- Know how CPT codes map to APC payment groups in the OPPS
Domain 3: Health Records and Data Content (16-20%)
This domain covers documentation requirements, data quality, and the health record elements that support code assignment. While your code books are less directly referenced here, the ICD-10-CM Official Guidelines contain documentation requirements you will annotate and need to recall quickly.
- Physician documentation requirements for code specificity
- Query processes when documentation is insufficient for code assignment
Domains 4-6: Compliance, Information Technology, Confidentiality and Privacy (5-14% each)
These domains test knowledge of HIPAA privacy rules, OIG compliance frameworks, health information systems, and data security. Your code books will not directly assist with these questions. Memorization and conceptual understanding carry you here.
- Domain 4 Compliance (10-14%): Fraud and abuse statutes, query compliance, coding ethics
- Domain 5 Information Technology (5-9%): EHR systems, data standards, interoperability
- Domain 6 Confidentiality and Privacy (5-9%): HIPAA Privacy Rule, minimum necessary standard, breach notification
Tabbing and Marking Your Books Before Test Day
The most effective CCA candidates treat their code books as personalized navigation tools. Here is a practical approach to book preparation:
ICD-10-CM Book
- Tab the Official Guidelines - These appear at the front of most editions. Mark Section I (conventions), Section II (outpatient selection), and Section III (inpatient selection) separately.
- Mark the Alphabetic Index vs. Tabular List boundary - A physical tab here prevents wasted searching time.
- Annotate combination code chapters - Chapters 1 (infectious diseases), 4 (diabetes), and 9 (hypertension/heart disease) are frequent exam territory. Write sequencing reminders in the margins.
ICD-10-PCS Book
- Write root operation definitions on a tabbed reference page or directly on the root operations table. The distinction between Excision, Resection, Destruction, and Repair is heavily tested.
- Mark the Medical and Surgical section table - This is your most-used section.
- Note body system prefixes - Write the body system character values on the section tab itself.
CPT Professional Edition
- Mark Appendix A (Modifiers) - Modifier questions appear regularly. A quick-access tab here saves significant time.
- Flag E/M guidelines - The 2021 E/M changes and the grid for MDM complexity are frequent test topics. Highlight the MDM table.
- Note surgery package components - Write the global period rules (0-day, 10-day, 90-day) in the Surgery section introduction.
Key Takeaway
Spend at least three full practice sessions navigating your physical books under timed conditions before test day. Familiarity with your own annotation system is as important as knowing the content itself. Use our CCA practice tests to simulate this process with the clock running.
Pearson VUE Test Center Logistics
The CCA is delivered exclusively through Pearson VUE's network of testing centers. Understanding what to expect when you arrive prevents last-minute stress from derailing your performance.
What to Bring
- Valid government-issued photo ID
- Your three approved code books (the physical, paper editions on AHIMA's approved list)
- Your Pearson VUE scheduling confirmation
What to Leave Behind
- Phones, tablets, and all electronic devices (stored in a locker at the center)
- Personal items, bags, and outerwear - Pearson VUE staff will secure these
- Any reference material that is not your approved code books
The exam offers no scheduled breaks within the two-hour window. If you leave the room for any reason, the clock continues. Plan accordingly - use the restroom before check-in, and keep water intake moderate in the hour before your appointment.
Exam fees are $299 for AHIMA members and $399 for non-members. Retake fees are the same as the original fee, which makes thorough preparation a financial priority as much as an academic one. If you need to understand what happens after you earn the credential, review the CCA Recertification Requirements 2026: CEUs and Fees so you understand the two-year certification cycle from the start.
A Domain-Weighted Prep Timeline
Given the domain weight distribution, your study time should not be distributed evenly. Clinical Classification Systems alone covers 30-34% of the exam. Here is a four-week framework built around that reality:
ICD-10-CM Deep Dive (Domain 1 Foundation)
- Read the Official Guidelines in full - annotate your physical book as you go
- Practice 20 diagnosis coding scenarios per day using your ICD-10-CM book
- Focus on Chapters 4 (endocrine), 9 (circulatory), and 19 (injury) - high-frequency exam topics
ICD-10-PCS and CPT (Domain 1 Completion)
- Master the seven-character PCS structure and the 31 root operations in the Medical and Surgical section
- Work through CPT E/M, Surgery, and Radiology sections with your annotated CPT book
- Complete timed practice test sessions covering Domain 1 question types
Reimbursement and Health Records (Domains 2 and 3)
- Study MS-DRG grouping logic and how principal diagnosis selection affects payment
- Review APC payment methodology and outpatient coding guidelines
- Focus on documentation standards and query processes for Domain 3
Compliance, IT, Privacy, and Full-Length Simulation
- Review HIPAA Privacy Rule fundamentals, OIG compliance elements, and coding ethics for Domains 4 and 6
- Cover EHR system basics and health data standards for Domain 5
- Take at least two full-length timed practice exams using your physical books alongside the test
For candidates pursuing recertification later, note that the two-year cycle and CEU requirements are covered in detail in the CCA Recertification Requirements 2026: CEUs and Fees article - worth reviewing even before you sit for the initial exam so you understand the full credential lifecycle.
Frequently Asked Questions
Binding style is generally not restricted as long as the edition and publisher appear on AHIMA's approved code book list. Confirm with your specific Pearson VUE center when you schedule, as individual centers may have specific policies about loose-leaf formats.
AHIMA's policy specifies one ICD-10-CM book, one ICD-10-PCS book, and one AMA CPT Professional Edition. You may not bring multiple editions of the same type or supplementary coding reference books, even if those books are otherwise legitimate coding resources.
Pearson VUE staff may not catch the error at check-in, but using an incorrect code year means you are referencing potentially outdated or incorrect codes during the exam itself. This directly harms your performance on Domain 1, the largest domain at 30-34% of your score. Always verify the applicable code year against your scheduled test date before your appointment.
Yes. Scores are reported on a scaled score scale of 100 to 400, and the passing score is 300. The exam contains 105 total questions, of which 90 are scored and 15 are unscored pretest items embedded throughout - you will not be able to identify which questions are unscored, so treat every question as if it counts.
AHIMA permits tabs for navigation purposes, but any content on or attached to those tabs must be your own handwriting - not printed text from an outside source. Pre-printed commercial tab sets that include coded content labels may be considered external reference material. Use plain tabs and write your own labels by hand to stay safely within the rules.
