Important CPC Exam Tip

For musculoskeletal and fracture questions, do not focus only on the name of the bone. Carefully look for:

1. Exact anatomical location
2. Right or left side
3. Type of fracture
4. Displaced or nondisplaced
5. Open or closed status
6. Encounter type
7. Healing status, when applicable
8. Procedure performed and technique

This is where many CPC students make mistakes.
