Which statement about the Place of Service (POS) code on CMS-1500 is true?

• A. It indicates the payer's processing facility
• B. It indicates where the service was provided; examples include Office, Inpatient Hospital, and Outpatient Hospital
• C. It indicates the diagnosis code category
• D. It indicates the order of CPT codes

Answer: (B)

Place of Service on the CMS-1500 shows where the service actually occurred. This matters because the setting (office, inpatient hospital, outpatient hospital, etc.) can influence payer rules, coverage, and reimbursement. For example, a service performed in a physician’s office uses the Office POS, while an outpatient department service uses Outpatient Hospital, and services during an inpatient stay use Inpatient Hospital. This field does not indicate the payer’s processing facility, nor does it relate to diagnosis code categories or the order of CPT codes.
