ICD-10-CM Guidelines Practice Exams
Focus your practice on ICD-10-CM guideline knowledge. Choose one of six gem-named exams or the complete six-exam bundle, with rationales to help you understand the reasoning behind each answer.
Practice is one part of your preparation.
Complementary ProductsCCO’s Proven Process for passing the certification exams includes: 1) Full Course (ICD-10-CM Diagnostic Coding Course), 2) Review Blitz (ICD-10-CM Review Blitz) and 3) Timed practice exams (this page and ICD-10-CM Practice Exams).
Plan your study windowEach purchase provides 30-day access. Purchase again if you need longer; access does not renew automatically.
Keep expectations clearThese are focused practice sets, not an official certification exam. A practice score does not guarantee a credentialing result.
Individual exams and bundle options
Each individual gem has 50 questions and its own answer rationales. Select a card to update the purchase panel.
All 6 exams bundle
Includes Titanite, Peridot, Obsidian, Citrine, Amber, Adventurine: 6 separate exams with 50 questions each.
Choose this bundleAccess is limited to the selected exam or the exams named in the selected bundle. Separate courses, Review Blitzes, books and certification fees are not included.
Turn practice into a focused study plan.
Pick your practice set
Choose the gem or bundle you want, and plan your study around the 30-day access window.
Work through the questions
Use your study references and set a time goal if useful. Follow the platform’s instructions for submitting your attempt and viewing results.
Study the rationales
Review both correct and incorrect answers. Identify what to revisit, then retake the same set during your access period to check your understanding.
Unlimited retakes during your access period
You may retake the purchased practice set during its 30-day access period. Retakes use the same questions rather than generating a new bank. Aim to understand the reasoning, not just memorize the answer letters.
Results and answer explanations
Online scoring and rationales help you review your attempt. Use the explanations to identify whether an error came from a knowledge gap, a guideline interpretation or a reference lookup.
These results describe your performance on this practice set, not a guaranteed score on a professional certification exam.
Where practice fits in the CCO Proven Process
Learn, review, practice. A full course builds the foundation, a Review Blitz refreshes it, and practice exams help you identify gaps.
Explore the related full course or explore the Review Blitz. These are separately purchased products.
Use your results to guide further study.
These focus areas help organize your preparation; they are not a promise of a fixed question distribution or an exact replica of any official exam.
Guideline knowledge
- Understanding ICD-10-CM guidance
- Interpreting coding instructions
- Applying guideline knowledge to coding decisions
Build a focused review plan
- Use answer rationales to identify gaps
- Revisit current guideline language
- Distinguish a guideline misunderstanding from a code-lookup mistake
Use current reference materials and check any professional exam provider’s current requirements separately.
Questions before you buy?
How long do I have access?
Each purchase gives you 30 days of access to the selected exam or bundle. If you need longer, you may purchase again. These are one-time purchases, not automatic subscriptions.
What does my selection include?
Each individual gem includes one 50-question practice set with answer rationales and retakes during the 30-day access period.
The bundle includes 6 separate exams: Titanite, Peridot, Obsidian, Citrine, Amber, Adventurine. That is 300 questions across the included sets, not a single 300-question exam.
Are the gem names difficulty levels?
No. Gem names identify different sets; they do not indicate beginner, intermediate or advanced levels, and there is no required gem order.
Will a retake or repurchase give me different questions?
No new question bank is promised. Retakes use the same questions in the named set. Purchasing again provides another access period, not a guarantee of new content. Choose a different gem if you want another listed practice set.
Is this an official certification exam?
No. This is independent CCO practice in ICD-10-CM guidelines. It does not award a professional credential and does not replace registration for an official certification exam.
No affiliation, endorsement or guaranteed pass result is implied. Official exam requirements are determined by the issuing organization.
Can I use the questions offline or as a printed exam?
These practice exams are delivered online, not as a downloadable question-bank product. You need internet access to use the platform. Check the current product terms if you have a specific accessibility or study-format need.
How do I access my purchase?
Follow the access instructions in your purchase confirmation. You can also start at CCO Login. If you cannot locate the purchased exam, contact CCO Support for help.
Are CEUs or a professional credential included?
No CEUs or professional certification are included. Any practice-exam completion certificate documents practice activity only; it is not a professional credential.
What is the refund policy?
CCO’s digital practice-exam purchases are nonrefundable. Confirm the gem or bundle, price and 30-day access terms before paying. Ask CCO for guidance if you are unsure.
