Diagnostic Imaging Associates, Inc.

Diagnostic Imaging Associates, Inc. NA Division, a for-profit medical services provider headquartered in Tulsa, Oklahoma, delivers remote diagnostic imaging interpretation services to the Indian Health Service as a prime contractor on full-and-open federal contracts with no set-aside designation. The company operates exclusively as a prime (100% of recent awards), competing for purchase orders, delivery orders, and blanket purchase agreements across a narrow customer base concentrated in Native American healthcare.

DIA's federal footprint is entirely centered on the Indian Health Service, which accounts for 371 of 376 awards (92% of award count) and $63.7 million of the $66 million combined potential value (96% of dollars). The top two customer rankings are identical — IHS dominates both volume and potential value — with the Department of Veterans Affairs, Peace Corps, and the Public Health Service each holding one to three awards. DIA's NAICS profile reflects its service model: Diagnostic Imaging Centers (255 awards), Offices of Physicians (82 awards), and Professional Organizations (19 awards) dominate the category concentration, with the Medical-Radiology PSC accounting for 322 of the awards.

DIA holds a $16.5 million single-award Indefinite Delivery Contract with IHS awarded June 20, 2025, through June 30, 2027, which is generating the majority of recent activity. As of November 2025, IHS had issued thirteen delivery orders under this IDC totaling approximately $2.87 million, with individual facility orders ranging from $3,691 to $873,943 and targeting service areas across Oklahoma, New Mexico, and South Dakota. Representative delivery orders include $400,000 for Clinton facility teleradiology (July 2026), $824,588 for Lawton facility region-wide services (June 2025), and $510,628 for Zuni service area (November 2025). DIA also holds subsidiary single-award blanket purchase agreements with IHS — a $25,000 BPA awarded July 21, 2022, supporting referral-basis diagnostic imaging at Claremore Indian Hospital through September 2025, and prior IDC vehicles including a $1.2 million contract (HHSI246200910017I, 29 task orders) and a $6.3 million contract (75H71125D00004, 24 task orders).

DIA's service delivery spans multiple imaging modalities — plain film radiography, mammography, computed tomography, ultrasound, dual-energy X-ray absorptiometry, and magnetic resonance imaging — along with transcription services and on-site radiology clinic support. The company has maintained federal contracting presence since 2004 and reports annual interpretation volumes exceeding 100,000 studies across IHS service regions. All work is performed in Tulsa, Oklahoma, with service delivery to Native American populations across Oklahoma, New Mexico, and South Dakota. Activity has grown over the past five years (13 awards in 2022, 22 in 2025), with ten awards valued at $2.4 million combined facing ultimate completion within the next twenty-four months and therefore exposed to recompete risk. The company operates on firm fixed-price pricing throughout its federal portfolio, and competing in full-and-open competition rather than under SBA set-asides has been its consistent posture across all named awards.
