Starting in October you need to focus on where the face-to-face service was performed. If you're in the dark about a new CMS place of service (POS) rule you could be attracting unwanted scrutiny for your face-to-face physician services, come October. The skinny: Important dates: Under CMS's announced rule, providers performing the PC [professional component] of interpretation of tests must use the POS where the face-to-face service -- test -- was performed, i.e. outpatient facility, ASC [ambulatory surgical center], etc. In case you have any question about whether the rule applies to diagnostic imaging, CMS clearly states in MLN Matters article 7631 that if the patient has an imaging exam at one site and the physician interprets the exam at his office, the POS should reflect where the patient had the exam. You should not base your POS code on where the physician provided the interpretation. For physician claims, you must decide whether to report office POS 11 for where the physician provided the service or POS 22 for the outpatient hospital where the patient had the exam. Under the new rule, you should report POS 22 because that's where the patient had the outpatient exam. Caution: An Inpatient Is Always an Inpatient for POS The MLN Matters article indicates two exceptions to the rule that the face-to-face service location decides the POS. Inpatient: If the patient is an inpatient of a hospital, then the POS will be the inpatient hospital POS 21 regardless of where the face-to-face visit occurs. Outpatient: Pay Particular Attention to ASCs Incorrect POS reporting for services performed in ASCs was one of the main motivators behind CMS providing these new and revised instructions. The ASC POS code is 24, and you should apply it when the face-to-face service occurs at an ASC. To clarify, if the physician has a separately maintained office space at the same physical location as the ASC, and it meets "distinct entity" requirements, then report office POS 11 for services performed in that office. But if the service occurs in the ASC, then you should report POS 24. Keep Your Practice in the Clear One of the main reasons CMS is so concerned about proper POS coding is that the agency doesn't want to overpay providers (non-facility rates are higher than facility rates in the fee schedule because a physician in a facility doesn't bear the same overhead costs as one performing services in his own space). As a coder, not only do you need to be sure you're reporting the proper POS for accurate reimbursement, you also need to be sure you append modifier 26 (Professional component) when you are reporting only the professional component of a code split into professional and technical components.
