PSC Q511

Overview

The Product Service Code (PSC) system is the federal taxonomy that classifies goods and services in government procurement records to improve contracting, reporting, and spend analysis. PSC entries appear in FPDS and SAM data and the PSC Manual on Acquisition.gov governs code definitions and use. ¹

PSC Q511 designates Medical‑Ophthalmology. Agencies assign Q511 to contract actions that procure ophthalmology services—clinical eye care, ophthalmic surgery, and related professional services—for reporting and analysis in FPDS. The code supports consistent spend classification for physician and surgical ophthalmology services. ²

Frequently asked questions

• Q: What does Q511 specifically identify in contract reporting?
  A: Q511 identifies procurement actions for ophthalmology services—clinical and surgical eye care—so agencies can classify and analyze spending on ophthalmologic professional services in FPDS. ²

• Q: Is Q511 used for optometry services?
  A: No. Optometry services are typically reported under PSC Q512; Q511 covers ophthalmology (physician and surgical) services. ²

• Q: Are medical supplies for ophthalmology reported under Q511?
  A: No. Supplies and equipment are generally reported under product PSCs (for example, optical instruments). Q511 is intended for professional ophthalmology services; specific supply PSCs depend on the item. ¹
