Overview

NAICS code 621111 covers establishments of health practitioners having the degree of M.D. (Doctor of Medicine) or D.O. (Doctor of Osteopathic Medicine) primarily engaged in the independent practice of general or specialized medicine (except psychiatry or psychoanalysis) or surgery.

Government healthcare programs create substantial opportunities for physician services. The Department of Veterans Affairs (VA) is the largest integrated healthcare system in the United States, employing physicians and contracting for physician services to supplement capacity. Community care programs allow veterans to receive care from private physicians.

Department of Defense provides healthcare through TRICARE, requiring network physicians across the country. Military Treatment Facilities (MTFs) supplement organic capability with contracted physician services. Indian Health Service (IHS) contracts with physicians to serve tribal communities.

Federal Occupational Health (FOH) provides physician services to federal employees. Immigration medical examinations require designated civil surgeons. Federal Bureau of Prisons contracts for physician services. Social Security disability determinations require physician evaluators.

Physician services contracting can range from locum tenens (temporary) staffing to long-term contracts. Telemedicine has expanded, particularly since COVID-19, creating opportunities for remote physician services. Credentialing requirements include state licensure, board certification, and often DEA registration.
