UNSPSC 85409301: Diagnosis of sinus, fistula and cyst of branchial cleft

This classification denotes the group of activities that yields a diagnosis of Sinus, fistula and cyst of branchial cleft. Sinus, fistula and cyst of branchial cleft is listed in the World Health Organization's International Statistical Classification of Diseases and Related Health Problems or ICD-10 as a four digit category under code Q18. 0

UNSPSC 85409301 Diagnosis of sinus, fistula and cyst of branchial cleft is a Commodity code that shows minimal alignment between its nominal scope and the state and local opportunities currently posted under it. The three recent solicitations tagged to this code span diagnostic imaging system procurement, school district special education contractor services, and health system temporary staffing — none of which map to clinical diagnosis of branchial cleft pathology. The mismatch suggests either a coding error in the source data or a broad classification interpretation by the issuing bodies that does not reflect the code's intended use in medical diagnosis and clinical services taxonomy.

The recent opportunities originate from California and Texas jurisdictions — San Mateo Medical Center (California), Birdville Independent School District (northeast Tarrant County, Texas), and Santa Clara County Health System (California) — but the work being solicited is not aligned with diagnosis of sinus, fistula, and cyst conditions. The San Mateo Medical Center RFP, posted October 7, 2026 with proposals due October 21, 2026, seeks a diagnostic imaging PACS implementation supporting radiology, cardiology, and dental imaging; the Birdville ISD solicitation (posted September 18, due October 21, 2026) requests special education contracted services across 23 line items including speech language therapists and occupational therapists; and Santa Clara Health System's RFQ (posted July 7, due October 7, 2026) establishes a qualified vendor pool for temporary health professional staffing in ancillary categories including diagnostic imaging and therapy services. This code shows little relevant recent procurement activity in its stated clinical domain.
