Infectious Disease Private Practices in Arizona (30 Verified Groups) | Daniel Aragón

There are 30 physician-owned infectious disease practices in Arizona, vetted against the NPPES NPI Registry. Hospital-employed, government, and academic positions are excluded.

Every group physicians still own.

Physician-Owned Infectious Disease Groups in Arizona

A vetted list of 46 infectious disease practices in Arizona that are still owned by the physicians who built them. Useful when the recruiter says you have no other options.

From your first MCAT prep book to your last in-training exam, the next step was always pre-written. Someone handed you the syllabus. You showed up. You did the work.

If a recruiter tells you the hospital is the only viable infectious disease employer within driving distance, you should be able to name five physician-owned groups that prove otherwise before the end of the call. This directory is how you get to five. The Real Contract course walks you through every clause that matters.

About this directory and the Arizona infectious disease market

Training ends. The map does not continue.

Then PGY-Final hits, and the page is blank. A recruiter calls. A contract lands in your inbox with a 50-mile non-compete, an opaque productivity model, and a signing bonus you do not understand the strings on.

Before you compare salary numbers, see how many physician-owned groups actually exist in your specialty and state. Then negotiate from leverage instead of from gratitude.

What other resources point to in Arizona

You're looking at 30 physician-owned infectious disease practices in Arizona. I sourced all of them from the NPPES NPI Registry and filtered out everything that doesn't meet the standard of independent physician ownership. Hospital systems, academic centers, staffing agencies, and corporate-acquired practices are not on this list. Each entry includes the practice address, phone, website, and NPI number. The coverage spans 9 cities statewide.

The reason this matters is that job boards don't distinguish between an independent infectious disease practice and a corporate medical group. They list them side by side, identical formatting, identical apply buttons. But the compensation model, the call schedule, the equity path, and the long-term upside are completely different depending on who owns the practice. This page separates the two. You can work through the list, contact practices directly, and skip the recruiter entirely.

The Arizona infectious disease market in detail

Arizona's physician-owned infectious disease directory lists 30 practice locations across 9 cities.

None of the infectious disease 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 9 cities including Avondale, Casa Grande, Chandler, and Flagstaff.

Frequently asked questions about infectious disease in Arizona

How many Infectious Disease private practices are in Arizona?

There are 30 physician-owned infectious disease 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.

Inpatient Consulting vs. Outpatient Models in Arizona Infectious Disease Practice

Arizona's physician-owned infectious disease practices include Infectious Disease Associates of Arizona (Phoenix, 5 physicians), Valley Infectious Diseases (Phoenix, 4 physicians), and Tucson Infectious Diseases Associates (Tucson, 4 physicians).

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 outpatient revenue sources do private infectious disease practices in Arizona use?

Private ID practices in Arizona with strong outpatient models often combine: HIV primary care (with Ryan White Title III grant funding where applicable, which supports the practice financially for uninsured patients), travel medicine (yellow fever vaccination, malaria prophylaxis, pre-travel consultations, largely cash-pay), and outpatient antibiotic infusion therapy (OPAT) for patients completing IV antibiotic courses at home or in the office. These outpatient revenue streams reduce dependence on hospital inpatient admissions volume.

Key Terms in Physician Contracts

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.
Collections-Based Compensation
A pay model in which a physician's income is tied directly to the revenue collected from their patient encounters. The physician typically receives a percentage of collections (40 to 55 percent is common) after overhead. This model rewards high-volume, high-acuity work but creates income variability.
Ryan White HIV/AIDS Program
A federal program providing funding to states, metropolitan areas, and clinics to provide care and treatment for low-income people living with HIV who lack adequate health coverage. Ryan White-funded clinics can receive grants that support clinical operations serving uninsured or underinsured HIV patients.
OPAT (Outpatient Parenteral Antibiotic Therapy)
Administration of intravenous antibiotics in an outpatient setting (home, infusion center, or physician office) for infections requiring prolonged IV treatment. OPAT services billed by the managing ID physician generate professional fee revenue; if the practice provides the infusion facility, additional facility fees may apply.
