FAQ

What work fits NAICS 621491?
  • Operate and staff a clinic providing primary medical care and preventive screenings for an assigned patient panel, including physicians, nurse practitioners, medical assistants, and care coordinators.
  • Provide point-of-care laboratory testing and basic radiology services with electronic health record integration for same-site diagnostics and result reporting.
  • Deliver chronic disease management clinics with scheduled follow-up, medication reconciliation, patient education, and measurement of disease-specific clinical metrics.
  • Manage referral pathways and specialty appointment coordination, including utilization tracking, referral status reporting, and closed-loop referral documentation.
When is NAICS 621491 a weak fit?
  • Urgent care centers: episodic, walk-in treatment focused on acute visits without an assigned managed enrollee panel or longitudinal care coordination that characterize HMO medical centers.
  • Stand-alone specialty outpatient clinics: single-specialty facilities that lack integrated primary care, enrollee panel management, and on-site coordination across multiple clinic services.
  • Residential skilled nursing facilities: require 24-hour licensed nursing care and overnight patient residence, elements absent from ambulatory HMO medical centers.
What solicitation language points to NAICS 621491?
  • Performance metrics specifying maximum panel size per clinician, appointment wait-time targets, and continuity-of-care measures used in evaluation.
  • Labor categories listing family medicine physicians, nurse practitioners, medical assistants, behavioral health consultants, and care coordinators with credentialing criteria.
  • Scope language requiring an integrated EHR with daily care summaries, on-site basic lab or imaging capabilities, and referral tracking workflows.
