Assign ICD10 Diagnosis Codes - Certified Professional Coder CPC

1. What does a "Code first" note in the Tabular List require you to do?

   Sequence the underlying condition code before the manifested condition code. 'Code first' notes require prioritizing the underlying etiology code before the manifestation code to reflect causal relationships accurately.

2. Which punctuation mark indicates "and/or" meaning in ICD-10-CM terms (e.g., "with/without")?

   The slash "/" indicates "and/or.". The slash in ICD-10-CM terminology allows for inclusive interpretation, representing alternatives such as presence or absence of a feature.

3. What does the Tabular instruction "Code also" mean for diagnosis code assignment?

   Code both conditions when documented; sequencing depends on circumstances. 'Code also' notes indicate that multiple codes may be assigned for coexisting conditions, with sequencing determined by the encounter's focus and guidelines.

4. Which Tabular note type allows coding of both conditions when appropriate: Excludes1 or Excludes2?

   Excludes2 (both conditions may be coded). Excludes2 notes permit coding both the code and the excluded condition if both are present and documented, allowing for comprehensive reporting.

5. Which Tabular symbol indicates an "Excludes1" note, and what does it mean for code assignment?

   Excludes1; conditions cannot be coded together at the same time. Excludes1 notes prohibit coding the excluded condition simultaneously with the code in question, as they are mutually exclusive per ICD-10-CM conventions.

6. Which ICD-10-CM convention uses parentheses ( ) to enclose nonessential modifiers?

   Parentheses ( ) indicate nonessential modifiers (do not affect code selection). Parentheses enclose supplementary terms that provide additional description but are not required for code assignment, enhancing clarity.

7. Which Index section is used to locate external cause codes by event (e.g., fall, motor vehicle crash)?

   External Cause Index. This Index organizes external causes alphabetically by event or mechanism, facilitating the assignment of codes for injuries or health impacts.

8. Identify the correct action if the Index provides a code but the Tabular List shows additional 4th-6th character options.

   Select the most specific Tabular code; do not stop at the Index code. The Tabular List provides the definitive structure and specificity, so coders must review it to assign the most precise code beyond Index suggestions.

9. What does the ICD-10-CM convention "and" mean when used in a code title or instruction?

   "And" means "and/or.". In ICD-10-CM code titles, 'and' is interpreted inclusively to mean either one or both conditions, allowing flexible application to documentation.

10. Which term in ICD-10-CM Index entries typically indicates a manifestation relationship: "with" or "without"?

    "With" (often links conditions that are coded together per guidelines). 'With' in Index entries assumes a linkage between conditions, guiding coders to combination codes or related classifications per guidelines.

11. Which Index instruction provides an optional additional place to look for more specificity?

    "See also" (optional cross-reference). The 'see also' instruction suggests checking another term for potentially more detailed or specific coding options, though it is not mandatory.

12. What does a "Use additional code" note in the Tabular List require you to do?

    Assign an extra code to fully describe the condition (when applicable). 'Use additional code' notes instruct adding supplementary codes to provide more detail on related factors or conditions when supported by documentation.

13. What does an instruction to use placeholder "X" in ICD-10-CM indicate?

    Insert "X" to fill empty characters and allow correct 7th character placement. The 'X' placeholder maintains the required code structure by filling positions, ensuring the 7th character can be correctly appended for specificity.

14. Which Index section is used to locate codes for drugs and chemicals causing poisoning or adverse effects?

    Table of Drugs and Chemicals. This specialized Index section categorizes substances and their effects, enabling coders to assign codes for poisoning, adverse effects, or underdosing.

15. What is the minimum number of characters required for a reportable ICD-10-CM code when more are available?

    Assign the code to the highest level of specificity available (all required characters). ICD-10-CM requires coding to the greatest detail available to ensure accuracy, meaning all applicable characters must be used for a valid code.

16. Which Tabular List note tells you to assign a 7th character, and what must you do if it is missing?

    "7th character required"; use placeholder "X" as needed to reach 7 characters. This note enforces the use of a 7th character for certain categories, with 'X' placeholders added to meet the seven-character requirement.

17. Which ICD-10-CM convention uses brackets [ ] to enclose synonyms or explanatory phrases?

    Brackets [ ] indicate synonyms, alternative wording, or explanatory phrases. Brackets in ICD-10-CM enclose supplementary information like synonyms or explanations to clarify code meanings without altering selection.

18. Which ICD-10-CM section is used to locate main terms and subterms for a diagnosis?

    The Alphabetic Index. The Alphabetic Index alphabetically lists diseases and conditions by main terms and subterms to direct coders to appropriate code ranges in the Tabular List.

19. What is the main term in the Index for the diagnosis statement "acute appendicitis"?

    Appendicitis. In ICD-10-CM, the main term is the condition itself, with 'acute' serving as a subterm modifier to specify the type of appendicitis.

20. What is the main term in the Index for the diagnosis statement "diabetic neuropathy"?

    Diabetes, diabetic. Diabetic conditions are indexed under 'Diabetes' or 'Diabetic' as the main term, with 'neuropathy' as a subterm to capture the manifestation.

21. Which ICD-10-CM book section provides the final, reportable code selection and full instructions?

    The Tabular List. The Tabular List organizes codes hierarchically with complete descriptions, notes, and conventions necessary for selecting the most specific and reportable diagnosis code.

22. What is the correct coding action when the Tabular List includes an "Includes" note under a category?

    Treat listed conditions as included examples for that category. 'Includes' notes expand the category's scope by listing examples of conditions that fall under it, aiding in appropriate code assignment.

23. Which Index instruction tells you to look elsewhere because the listed term is not the correct entry?

    "See" (mandatory cross-reference). The 'see' instruction in the Index requires redirecting to an alternative term for the correct code, as the initial entry does not lead to the appropriate classification.
