ICD 10 Questions and Answers

What is the ICD-10 coding system?

ICD-10 (International Classification of Diseases, 10th Revision) is the standardized medical coding system used in the United States for classifying diagnoses, symptoms, and procedures. ICD-10-CM covers clinical diagnoses with over 70,000 codes, while ICD-10-PCS contains approximately 78,000 procedure codes used exclusively in inpatient hospital settings. All HIPAA-covered entities have been required to use ICD-10 since October 2015.

What format does the ICD-10 certification exam follow?

The format depends on which certification you pursue. The AAPC's CPC exam consists of 100 multiple-choice questions to be completed in 4 hours. The AHIMA's CCS exam includes both multiple-choice and fill-in-the-blank questions covering ICD-10-CM, ICD-10-PCS, and CPT coding. Both exams are proctored and require applying codes to real-world clinical scenarios rather than simple memorization.

How many questions are on ICD-10 certification exams?

The CPC exam from AAPC contains 100 multiple-choice questions. The AHIMA CCS exam has approximately 97 questions split between multiple-choice items and coding case studies. The AHIMA CCA exam, an entry-level option, contains 100 multiple-choice questions. Each exam allocates different time limits, with the CPC allowing 4 hours and the CCS allowing approximately 3 hours and 40 minutes.

What is the passing score for ICD-10 certification exams?

The AAPC CPC exam requires a score of 70% or higher to pass, meaning you must answer at least 70 out of 100 questions correctly. AHIMA uses a scaled scoring method for the CCS and CCA exams, with scores ranging from 100 to 400 and a passing threshold typically set at 300. AHIMA does not publish a fixed percentage-based passing score.

What topics are covered on ICD-10 certification exams?

ICD-10 certification exams cover ICD-10-CM diagnosis coding, ICD-10-PCS procedure coding, CPT and HCPCS Level II coding, medical terminology, anatomy and physiology, coding guidelines, compliance and regulatory standards, and reimbursement methodologies. You will also be tested on reading operative reports, applying modifier codes, and understanding payer-specific documentation requirements across outpatient and inpatient settings.

What are the eligibility requirements for ICD-10 certification?

The AAPC CPC exam has no strict prerequisites, though AAPC recommends completing a medical coding training program. Without two years of professional experience, you receive a CPC-A (Apprentice) credential until the experience requirement is met. AHIMA's CCS exam recommends at least three years of coding experience or completion of an AHIMA-approved coding education program. The entry-level CCA has no formal experience requirement.

How do I register for an ICD-10 certification exam?

For AAPC certifications, create an account at aapc.com, select your exam, and pay the registration fee of approximately $399 for members or $499 for non-members. For AHIMA certifications, apply through ahima.org with fees around $299 for members or $399 for non-members. Both organizations offer online proctored exams and in-person testing at approved locations throughout the year.

What are the best preparation strategies for ICD-10 certification exams?

Focus on timed practice exams to build speed, since time management is the most common reason candidates fail. Tab and highlight your codebooks thoroughly before exam day, as both major exams are open-book. Study the Official ICD-10-CM Guidelines for Coding and Reporting published by CMS, practice coding from real operative reports, and memorize the structure of ICD-10 chapters so you can locate codes quickly during the test.
