PSC Q510

Overview

The Product Service Code (PSC) system is a government-wide taxonomy used to classify goods and services procured by the U.S. federal government. PSC codes appear in procurement reporting systems such as FPDS and SAM to identify what was purchased, supporting spend analysis, category management, and consistent agency reporting; the PSC Manual is the authoritative maintenance document for the program and defines code-level inclusions and exclusions that agencies must follow when reporting awards. ¹

PSC Q510 is listed in the PSC Manual under Category Q (Medical) as Medical‑ Neurology (Neurology Services). The official entry defines included services (neurologists and associated technologists, EEG, intraoperative neurophysiologic monitoring, long‑term monitoring, autonomic testing, neuromonitoring and sleep medicine) and provides explicit excludes for surgical specialties and medical devices; agencies record PSCs in FPDS using the dominant service or product as reported in the award record. ¹

FPDS reporting and usage

Federal award records in FPDS use PSCs to indicate the primary service purchased; PSC Q510 appears in agency FPDS records for contracts and orders that predominantly procure neurology services or neuromonitoring. Agencies are instructed to select the PSC based on the predominant product or service value in the award; detailed award searches and analytics for PSCs are available via FPDS ezSearch. ²

Frequently asked questions

• What does PSC Q510 explicitly include?
  The PSC Manual lists inclusions such as neurologists, neurology technicians, EEG technologists, CNIM intraoperative monitoring technologists, long‑term monitoring technologists, autonomic testing professionals, neuromonitoring services, and sleep medicine services delivered by neurology/sleep specialists. ¹

• Are neurosurgeons or neurosurgical procedures covered by Q510?
  Neurosurgery and neurosurgeons are explicitly excluded from PSC Q510; those services are reported under surgical PSCs (for example surgical PSCs in Category Q such as Q523 where applicable). ¹

• How should agencies choose the correct PSC when a contract includes devices and clinician services?
  FPDS guidance directs selection of the PSC for the predominant product or service by dollar value. If the acquisition is mainly clinical services, a medical service PSC such as Q510 is appropriate; equipment and supplies should be coded to product PSCs. ¹

• Where can FPDS award data be searched by PSC and analyzed?
  Use FPDS ezSearch to search awards and IDVs by PSC value; ezSearch returns reported NAICS, PSC, and award metadata. FPDS help pages provide guidance and examples for constructing searches and interpreting results. ²
