This happens when you use an old technology that the Centers for Medicare and Medicaid Services (CMS) discourages, like computed radiography (CR) or cassette-based imaging.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You can get your reimbursement reduced by more than 10% for computed radiography. The question is: if you perform both a CR X-ray and a digital X-ray, how will you differentiate them on a claim?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The answer is the FY modifier.

But it\u2019s not. Let\u2019s discuss what this means.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Computed radiography is an older form of digital X-ray. It works like a film cassette in principle, but the difference is that it produces a digital image. Even though CR produces a digital image, CMS treats it as any other cassette-based imaging.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But why do you need to append this? Well, the Consolidated Appropriations Act of 2016 was passed to move healthcare providers away from older imaging techniques, including CR X-rays. For this, the CMS <a href=\"https:\/\/www.itnonline.com\/content\/decoding-consolidated-appropriations-act-2016\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">reduced the reimbursement amount for CR X-rays<\/a>. That\u2019s why if you perform computed radiography, you must append the FY modifier to tell the payer that the imaging was done via older technology.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The important thing to understand here is that FY does not represent performing the X-ray itself. It just points to the method used for imaging. Also, you cannot charge the patient for the reduced amount.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Scenarios Where the<\/strong> <strong>FY Modifier<\/strong> <strong>is Applicable<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Let\u2019s look at a couple of real-world scenarios in which the FY modifier can be used:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Scenario 1<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Suppose a patient comes to a medical practice. He has a persistent cough that isn\u2019t getting better with over-the-counter medications. The attending physician examines the condition and orders a chest X-ray with two views. The practice has its own imaging service. However, it uses an imaging system with cassettes and imaging plates, so the study is a CR X-ray.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The physician interprets the imaging results and provides the necessary treatment. Here, the billing department can use the FY modifier along with the appropriate CPT code to bill the X-ray.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Scenario 2<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Let\u2019s look at another scenario. Suppose a man falls while playing football. His wrist becomes swollen, and he feels severe pain. He then visits the nearest orthopedic clinic. The physician orders an X-ray of the wrist. However, the clinic uses an old CR system for imaging. The results are obtained, and the physician finds a clear fracture.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Necessary treatment is provided to the patient. In this case, the billing department can use the FY modifier to indicate that the X-ray was performed on a CR system.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>FY Modifier<\/strong> <strong>\u2013 Billing Guidelines<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">We have covered the basics. Now, let\u2019s discuss some important guidelines that will help you use modifier FY correctly in your claims. Take a look:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Both CR and DR Images<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If you perform an X-ray with both CR and DR methods, and some images are from a CR cassette and the rest come from a DR panel, there won\u2019t be any reduction in the reimbursement amount.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">CMS has clarified that if the imaging service combines both methods, then the reduction does not apply.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Know Which Component is Reduced<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The reduction applies only to the technical component and the TC of the global fee. The professional interpretation\u2019s payment is not reduced by FY.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You might think that with a 10% reduction and that too only on the technical component, the cut is too small. However, when compounded over hundreds of claims, the amount becomes significant.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Sequence FX and FY Correctly<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Some codes may carry both modifiers FX and FY.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&nbsp;In that case, the FX reduction is applied first, and the FY reduction follows.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Conclusion<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">We have reached the end of this guide. Since there is a lot of information to keep track of, let\u2019s quickly recap the essential points:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The FY modifier reports an X-ray taken using computed radiography or cassette-based imaging.<\/li>\n\n\n\n<li>Reimbursement is reduced only for the technical component by 10%.<\/li>\n\n\n\n<li>FY is not needed for digital radiography, packaged X-rays, or studies that combine CR and DR images.<\/li>\n\n\n\n<li>Sequence FX before FY.<\/li>\n<\/ul>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Radiology billing can be frustrating and complicated if you don\u2019t know how to tackle the complexities.
