FWA Insights: How SIUs can identify misuse of the unlisted home visit code

Cotiviti Blog · 5 days ago · 9 views

Unlisted procedure codes play an important role in healthcare billing, allowing providers to report services that do not have a more specific CPT or HCPCS code. But because these codes are inherently less defined, they can also create vulnerabilities when used too broadly, too frequently, or without clear documentation. CPT 99600, an unlisted code used to bill for home visit services or procedures, is one such code that may warrant closer review when billing patterns appear atypical. In this edition of FWA Insights, we explore how special investigative units (SIUs) can identify potential misuse of CPT 99600 by combining claims data analysis, peer benchmarking, and documentation review to better understand whether billing behavior reflects legitimate care delivery or possible fraud, waste, and abuse (FWA).
