Title: Imaging of Rheumatic Diseases I: Ultrasound

Session Type: ACR Concurrent Abstract Session

Session Time: 2:30PM-4:00PM

Background/Purpose:

MSK-US use has risen in the USA with recent disturbing findings suggesting greater utilization of interventional ultrasound by non-noradiologists compared to Radiologists. (1) This study evaluated utilization of diagnostic and interventional MSK-US within the Medicare population in the USA from 2011 – 2013. Our objectives were to estimate the rate of MSK-US utilization by MSK specialties, compare the cumulative growth of services and payments as well as determine time trends of utilization within the study period.

Methods:

A retrospective cross-sectional analysis of Medicare Physician Supplier Payment Summary (PSPS) files from 2011 – 2013 was used to tabulate services and total payments on utilization. PSPS data is aggregated by multiple factors but excludes technical costs such as those billed by Radiology. Therefore, service count data more accurately reflects utilization across specialties. CPT 76881, 76882; and 76942 were coded as diagnostic ultrasound and interventional ultrasound respectively. Non-duplicative billing claims of these codes were summed for each years and provider specialty. Descriptive  and statistical (ANOVA) analysis was conducted using SAS® for Windows Ver. 9.4.

Results:

There was greater utilization of interventional than diagnostic ultrasound among all MSK providers except Podiatry. (Table, Fig) Amongst non-radiology groups, a cumulative growth of up to 205% and 273% was seen in interventional and diagnostic ultrasound respectively, while there was a decrease in Radiology interventional services.  Orthopedics and Rheumatology had higher mean number of services and payments compared to all other non-radiology specialties (p<0.05). (Fig)

Conclusion:

Marked dissociation of interventional MSK-US services from diagnostic services was seen in most MSK specialties. Orthopedics ranked highest for MSK-US interventional services. Lack of corresponding diagnostic billing could be due to bundling of diagnostic services or inability to acquire and bill diagnostic ultrasound. Although the rapid rise of utilization of interventional MSK-US could reflect innovation in care, it is not clear if addition of MSK-US ultrasound guidance on a population level leads to better value care. Medicare reimbursement of interventional MSK-US procedures has been reduced which may lead to a better value proposition and moderated utilization.

All abstracts accepted to ACR Convergence are under media embargo once the ACR has notified presenters of their abstract’s acceptance. They may be presented at other meetings or published as manuscripts after this time but should not be discussed in non-scholarly venues or outlets. The following embargo policies are strictly enforced by the ACR.

Accepted abstracts are made available to the public online in advance of the meeting and are published in a special online supplement of our scientific journal, Arthritis & Rheumatology. Information contained in those abstracts may not be released until the abstracts appear online. In an exception to the media embargo, academic institutions, private organizations, and companies with products whose value may be influenced by information contained in an abstract may issue a press release to coincide with the availability of an ACR abstract on the ACR website. However, the ACR continues to require that information that goes beyond that contained in the abstract (e.g., discussion of the abstract done as part of editorial news coverage) is under media embargo until 10:00 AM ET on November 14, 2024. Journalists with access to embargoed information cannot release articles or editorial news coverage before this time. Editorial news coverage is considered original articles/videos developed by employed journalists to report facts, commentary, and subject matter expert quotes in a narrative form using a variety of sources (e.g., research, announcements, press releases, events, etc.).

Violation of this policy may result in the abstract being withdrawn from the meeting and other measures deemed appropriate. Authors are responsible for notifying colleagues, institutions, communications firms, and all other stakeholders related to the development or promotion of the abstract about this policy. If you have questions about the ACR abstract embargo policy, please contact ACR abstracts staff at [email protected].
