Using AI for ICD-10 Code Lookup Quiz

Answers and explanations appear as you take the quiz.

1. Why can a general-purpose chatbot return an ICD-10-CM code that does not exist?
   • It deliberately swaps codes to protect patient privacy
   • It produces text that fits learned patterns, without checking against the official code table
   • It only knows ICD-9 codes and converts them incorrectly
   • It is legally barred from using the current code set
2. According to the official guidelines, what is the correct order for finding a code?
   • Search the Tabular List only, since the Index is optional
   • Use whichever code the EHR problem list shows
   • Look the term up in the Alphabetic Index, then confirm it in the Tabular List
   • Ask a chatbot first, then check the Alphabetic Index
3. When do ICD-10-CM code set updates take effect each year?
   • October 1
   • January 1
   • July 1
   • Whenever a payer requests a change
4. An outpatient note says "probable pneumonia" and documents cough and fever. What should be coded?
   • The pneumonia code, since "probable" counts as confirmed
   • Nothing, until a chest X-ray is read
   • An unspecified infection code chosen by the AI
   • The documented signs and symptoms, such as cough and fever
5. A chatbot suggests an ankle sprain code with no seventh character. Why should the coder reject it?
   • Seventh characters are only used for inpatient claims
   • The Tabular List requires a seventh character for that injury category, so the code is incomplete
   • Sprains cannot be coded with ICD-10-CM
   • Chatbot codes are always one character too long
6. What does an Excludes1 note in the Tabular List tell a coder?
   • The two conditions generally should not be coded together
   • The condition must always be coded first
   • The code has been deleted this year
   • The code needs payer prior authorization
7. Which design choice most reduces invented codes in an AI lookup tool?
   • Letting the model freely write codes but asking it to be careful
   • Training the model on older code books for more history
   • Restricting the model to candidates retrieved from the current official files, then checking them against fixed rules
   • Hiding the code descriptions from the user
8. What does the guide say about unspecified ICD-10-CM codes?
   • They are banned on all claims
   • They are acceptable when the documentation does not support a more specific code
   • They must always be replaced by whatever the AI infers
   • They are only valid before October 1
