UNSPSC 85451100 Diagnoses of other, special examinations and investigations of persons without complaint or reported diagnosis is a Class code that captures diagnostic imaging systems, health professional staffing for specialized clinical assessments, and contracted diagnostic and therapeutic services that state and local health systems and school districts procure to supplement in-house clinical capacity. State and local buyers under this code include public hospital systems, county health authorities, and school districts seeking temporary or permanent augmentation of diagnostic and therapeutic capability. Recent solicitations show two distinct procurement tracks: enterprise-grade diagnostic imaging infrastructure (picture archiving and communication systems with electronic health record integration, 3D visualization, and data migration capability) and contracted staffing for ancillary health professionals including audiologists, diagnosticians, dyslexia evaluators, physical and occupational therapists, speech language pathologists, and vision specialists. School districts are treating this code as a vehicle for special education evaluations and related services, while hospital systems use it to fill temporary clinical staffing gaps across radiology, cardiology, gastroenterology, and therapy specialties.
