Diagnostic Radiology Private Practices in Arizona (76 Verified Groups) | Daniel Aragón
There are 76 physician-owned diagnostic radiology practices in Arizona, vetted against the NPPES NPI Registry. Hospital-employed, government, and academic positions are excluded.
Every group physicians still own.
Diagnostic Radiology Practice Directory: Arizona
Before you accept a hospital offer in Arizona, see how many physician-owned diagnostic radiology groups already exist. The answer is 121, and it changes everything you can ask for in negotiation.
For 15 years the path was visible. Pre-clinical, clinical, sub-I, Match, intern year, residency, fellowship. Every transition had a name and a date.
Most diagnostic radiology physicians sign their first contract without knowing how many other groups exist within driving distance. This is the single largest source of leverage you give away in your career, and you give it away because nobody told you the information was out there. The Real Contract course walks you through every clause that matters.

About this directory and the Arizona diagnostic radiology market
For 15 years you had a map. Then the map ran out.
Then PGY-Final arrives. Suddenly there is no syllabus, no advisor telling you which clause to push back on, no upperclassman who has done this before. There is only a contract and a clock.
Nobody is telling you what other diagnostic radiology practices exist in Arizona, what the contract really says, or which lawyer to call. The senior people in your program signed without reading because they had no guide either. This directory is the first page of the map.
What other resources point to in Arizona
Here's what this page is: 121 diagnostic radiology practices in Arizona that are physician-owned. Not hospital jobs. Not corporate medical groups. Not locum postings. Every listing was pulled from the federal NPPES database and verified for active NPI status. I've supplemented each one with contact info, websites, and Google Maps links from DataForSEO. The practices span 13 cities across the state.
If you're evaluating a move to private practice in Arizona, this is a starting point you won't find on a job board. Most boards mix employed positions with ownership opportunities, and they almost never tell you who actually owns the practice. Recruiters aren't much better. This page filters for physician ownership specifically, so you can focus on practices where clinical autonomy isn't just a talking point in an interview. It's built into the ownership structure.
The Arizona diagnostic radiology market in detail
Arizona's physician-owned diagnostic radiology directory lists 76 practice locations across 12 cities. The largest groups include Modern Vascular (4 locations), Manntej Sra, MD (3 locations), and Dr. Joel R. Rainwater, MD (2 locations).
None of the diagnostic radiology practices listed in Arizona carry a PE-Backed or Corporate-Acquired flag. All listings in this directory are physician-owned independent practices verified through NPPES.
Practices span 12 cities including Chandler, Flagstaff, Gilbert, and Glendale.

Frequently asked questions about diagnostic radiology in Arizona
How many Diagnostic Radiology private practices are in Arizona?
There are 76 physician-owned diagnostic radiology private practices in Arizona, verified against the NPPES NPI Registry. All are independently operated. Hospital-employed, government, corporate, and academic positions are excluded.
What does physician-owned mean?
A physician-owned practice is one where licensed physicians hold controlling ownership of the business entity. This is distinct from hospital employment, corporate medical groups, or private equity-backed practices where non-physician entities control the business.
What does the Corporate-Acquired or MSO-Affiliated flag mean?
The Corporate-Acquired flag means the practice was historically physician-owned but has since been acquired by a corporate entity such as Optum. The MSO-Affiliated flag means the practice uses a Management Services Organization for billing and administration while physicians retain practice-level ownership.
Independent Contractor vs. Employee Status for Radiologists in Arizona
Arizona has 6 physician-owned diagnostic radiology practices across 4 cities. The larger groups include Valley Radiologists Ltd (Phoenix), Southwest Diagnostic Imaging (Phoenix), and EVDI Medical Imaging (Mesa). SimonMed Imaging (headquartered) and Radiology Partners Arizona are ...
What is an NPPES-verified practice?
NPPES is the National Plan and Provider Enumeration System, a federal database maintained by CMS. Every practice in this directory has an active NPI record in NPPES, confirming it is a registered U.S. medical practice.
What is the difference between a W-2 and 1099 arrangement for radiologists in Arizona?
Under a W-2 arrangement, the radiology group withholds income taxes, pays half of FICA taxes, and typically provides benefits. Under a 1099 independent contractor arrangement, you pay self-employment tax (15.3% on earnings up to the FICA cap), fund your own benefits, and are responsible for quarterly estimated tax payments. The 1099 gross income is often higher to compensate, but confirm who pays malpractice coverage, as this is a major variable in your net income calculation.

Key Terms in Physician Contracts
PLLC (Professional Limited Liability Company)
A hybrid entity combining LLC flexibility with professional licensing requirements. PLLCs are common for physician-owned practices in states that permit them. They offer pass-through taxation and personal liability protection for non-malpractice claims.
MSO (Management Services Organization)
A non-physician entity that provides administrative infrastructure (billing, coding, EHR support, payer contracting) to physician-owned practices. MSO arrangements let physicians retain clinical and practice ownership while outsourcing back-office operations. Private equity commonly uses MSO structures to influence practice operations without technically owning the medical entity.
NPI (National Provider Identifier)
A unique 10-digit number assigned to every U.S. healthcare provider and organization by CMS. Individual physicians receive a Type 1 NPI; practice entities receive a Type 2 NPI. The NPI is used across all payers for billing and credentialing.
Restrictive Covenant
Any contractual clause that limits a physician's professional activities after leaving an employer. Non-compete clauses are the most common restrictive covenant, but the category also includes non-solicitation clauses (prohibiting contact with former patients or staff) and non-disparagement clauses.
Fair Market Value
The price at which a willing buyer and willing seller would agree to transact, with both parties having reasonable knowledge of the relevant facts. Physician compensation must meet fair market value to comply with federal anti-kickback and Stark Law requirements. Independent valuations are used for buy-in pricing, compensation benchmarking, and practice sales.
Independent Contractor (1099)
A worker classification where the physician is not an employee of the practice but provides services under a contract. The physician is responsible for self-employment tax, benefits, and typically their own malpractice coverage. Gross income is often higher than W-2 equivalents to compensate for these costs.
Exclusivity Clause
A contract provision that prohibits a physician from providing services to any other entity during the contract term. Common in radiology contractor agreements. Limits your ability to moonlight, read for other groups, or take coverage assignments.
