PSC Q509

Overview

The Product Service Code (PSC) is the U.S. federal government’s standardized classification system used to categorize goods and services in contracting, award reporting, and spend analytics. Agencies apply PSCs in reporting systems such as the Federal Procurement Data System (FPDS) and SAM, and updates to the set of PSCs and their descriptors are published in the Product and Service Code Manual on Acquisition.gov. ¹

PSC Q509 is listed as "Medical — Internal Medicine" in the official PSC listings and is the code used in federal procurement records to identify awards for internal and family medicine professional services and related clinical support when agencies designate that PSC on an action. Specific inclusions, exclusions, or provider‑level detail are presented only in the official PSC listings or in agency solicitations and are not enumerated beyond the descriptor in the PSC Manual. ¹

Contracting considerations

• Performance location, scope of services, credentialing, privileging, and personnel requirements are typically specified in the solicitation, statement of work (SOW), or task order rather than in the PSC descriptor; contracting officers and program offices establish clinical credentialing and privacy (HIPAA) expectations. Not specified by official sources ¹.
• Billing, reimbursement, and place‑of‑service rules (for example, Medicare/Medicaid) are governed by CMS and other benefits authorities; the PSC is a classification for reporting and does not by itself establish billing rules. Not specified by official sources ¹.
• When multiple clinical service types are required under a single procurement, agencies may assign one PSC that best fits the primary service or multiple PSCs where allowed by reporting rules; see agency guidance and FPDS coding instructions for reporting practice. Not specified by official sources ¹.
