Final answer:
The CPT® code for reporting moderate sedation during the repair of the laceration in a 5-year-old patient is 99148 x 2.
Step-by-step explanation:
The CPT® code for reporting moderate sedation during the repair of the laceration in a 5-year-old patient is 99148. This code is used when a provider administers sedation to a patient under the age of 5 years old. The code includes the initial 15 minutes of moderate sedation. Additionally, since the procedure took 30 minutes, an additional unit of time (30 minutes) should be reported with the code. Therefore, the final code reported would be 99148 x 2.
