- Coding procedures based on the time of day
- Using time as a key component in determining the level of E/M service
- Assigning codes based on appointment duration
- Coding only emergency services
Answer: B
Explanation: Time-based coding is used in E/M services when the time spent with the patient is the key factor in selecting the code.
