DIRECTIONS: Your presentation must include answers to the following questions:

Why should we be aware of GEMs? How might you use them in your future career?
List each code assigned and the code or codes that are its equivalent. If the ICD-9 code maps to more than three ICD-10 codes, only list three and note that there are others.
Discuss each code and its equivalent code(s).
Do the codes have different descriptions? Give examples.
Is one code more specific than the other? Give examples.
Do any of the codes have more than one equivalent or require multiple codes?
Finally, summarize your assessment of ICD-10, GEM’s, and this assignment as a tool for showing the importance of coding from a billing, health care quality and cost perspective.
Pick one (1) ICD-9-CM code in each section for a total of 3 diagnosis and procedure codes mapped to ICD-10-CM and ICD-10-PCS codes.
