PSC Q515: Medical - Pathology — Active Federal SAM.gov Contracts & NAICS Crosswalk

Federal procurement intelligence, spending breakdown, NAICS/NIGP crosswalk, and contract capture guide for PSC Q515 (Medical - Pathology).

Product and Service Code (PSC) Q515 — Medical - Pathology — is an official federal procurement classification within Portfolio Q — Medical Services managed by the General Services Administration (GSA) under the Federal Procurement Data System (FPDS) Product and Service Codes Manual. Across federal agencies, contracting officers obligate approximately $1.9 Billion annually under PSC Q515, with 310+ Bids active solicitations, pre-solicitation notices, and task order RFQs circulating on SAM.gov and agency e-Buy portals. While a 6-digit NAICS code defines a contractor's overall industry and Small Business Administration (SBA) size standard, PSC Q515 specifies the exact medical service (lab) deliverable being purchased on the contract line item (CLIN). In federal solicitation architecture, PSC Q515 is most frequently paired with Primary NAICS 621511 (Medical Laboratories), which carries an SBA small business size standard of $41.5 Million. Major buying commands—led by Department of Veterans Affairs (48% of spend), Department of Defense (28%), and Department of Health and Human Services (CDC/NIH) (18%)—use PSC Q515 to categorize statements of work encompassing CLIA/CAP Certified Reference Laboratory Testing, Blood Chemistry & Microbiology; Anatomic Pathology, Histopathology, Cytopathology & Molecular Genomic Sequencing; and Federal Workplace Drug Testing, Forensic Toxicology & Infectious Disease PCR Screening. Understanding how contracting officers cross-walk PSC Q515 with NAICS 621511 is critical because many agencies filter dynamic small business searches, GSA e-Buy distributions, and historical FPDS incumbent spend analyses by PSC rather than NAICS alone. Procurement teams issuing awards under PSC Q515 utilize a mix of open-market SAM.gov solicitations and pre-competed contract vehicles such as GSA MAS 621 II. Depending on the acquisition threshold and market research results from Sources Sought notices, contracting officers frequently restrict PSC Q515 competitions to certified small businesses—including 8(a) Business Development participants, Service-Disabled Veteran-Owned Small Businesses (SDVOSB), Women-Owned Small Businesses (WOSB), and HUBZone firms. Offerors responding to PSC Q515 RFPs must demonstrate strict compliance with applicable FAR and DFARS clauses, deliverable quality standards, and supply-chain or labor regulations. For contractors expanding across both federal and state/local (SLED) markets, PSC Q515 maps directly to NIGP Commodity/Service Code 948-55 (Medical, Clinical, Forensic, and Diagnostic Laboratory Testing Services) used by state procurement portals, municipal purchasing departments, public universities, and K-12 school districts. InTandem's automated government contracting platform continuously monitors live SAM.gov notices tagged with PSC Q515 alongside matching state and local NIGP 948-55 bids, enabling capture teams to uncover hidden opportunities and generate compliant proposals faster.
