A Routine pap smear

You are a medical assistant who works for a small OB/GYN practice. A common procedure performed daily for many patients is a routine pap smear. Perform some research and share what the HCPCS code would be if this procedure was performed on a Medicare patient. Additionally, provide two examples of when these codes would be used in an inpatient setting and two additional examples of when HCPCS codes would be used in an outpatient setting.
