Allergy & Immunology Private Practices in Mississippi (19 Verified Groups) | Daniel Aragón

There are 19 physician-owned allergy & immunology practices in Mississippi, vetted against the NPPES NPI Registry. Hospital-employed, government, and academic positions are excluded.

Where allergy & immunology stays physician-owned.

Allergy & Immunology Practice Directory: Mississippi

29 independent allergy & immunology practices across Mississippi, cross-referenced against NPPES, state medical boards, and each practice's own website. Negotiate from leverage instead of from gratitude.

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.

Once you can name three independent allergy & immunology groups in your target city, every clause in your hospital contract becomes negotiable in a way it was not five minutes ago. The same non-compete, the same productivity formula, the same partnership track suddenly have something to be measured against. The Real Contract course walks you through every clause that matters.

About this directory and the Mississippi allergy & immunology market

Training ends. The map does not continue.

Then you hit your last year of training and the structure ends. Someone wires you a stipend to come look at a hospital. Someone else sends an MSA with a non-compete you do not have time to read.

The senior residents signed their first contracts without reading every clause. Not because they did not care, but because nobody had handed them a map of what else existed. So they took the first offer. This directory exists so you do not have to.

What other resources point to in Mississippi

What you'll find here is a complete list of 19 physician-owned allergy & immunology practices in Mississippi, verified against the NPPES NPI Registry. I started with the full federal database and worked backwards, removing every practice that doesn't qualify as independently operated. No hospital jobs. No PE-backed groups. No staffing agencies. Just 29 practices across 9 cities where physicians own the entity and control the clinical direction.

The reason this matters is that job boards don't distinguish between an independent allergy & immunology 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 Mississippi allergy & immunology market in detail

Mississippi's physician-owned allergy & immunology directory lists 19 practice locations across 8 cities. The largest groups are Mississippi Asthma Allergy Clinic, P.A. (2 locations) and Mississippi Asthma & Allergy Clinic, P.A. (2 locations).

Practices span 8 cities including D'Iberville, Gulfport, Hattiesburg, and Jackson.

Frequently asked questions about allergy & immunology in Mississippi

How many Allergy & Immunology private practices are in Mississippi?

There are 19 physician-owned allergy & immunology private practices in Mississippi, 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.

Allergy Testing and Immunotherapy Revenue in Mississippi

Mississippi's physician-owned allergy & immunology practices include Mississippi Asthma & Allergy Clinic (Jackson), Hattiesburg Clinic - Allergy (Hattiesburg, founded 1963), and The Allergy & Asthma Clinic of MS Coast (Gulfport).

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.

How does immunotherapy administration generate revenue in allergy-immunology private practice in Mississippi?

Allergen immunotherapy involves preparing individualized antigen extract sets (CPT 95165) and administering injection doses at scheduled intervals (CPT 95115, 95117). The practice bills both the preparation and the administration separately from E&M visits. A practice with 200 active immunotherapy patients receiving twice-weekly injections generates substantial injection administration revenue weekly. Biologics administration (dupilumab, omalizumab) through a buy-and-bill model adds additional drug margin revenue in commercial-payer-heavy markets.

Key Terms in Physician Contracts

PC (Professional Corporation)
A state-chartered corporation formed by licensed professionals. Physicians use PCs to own and operate their practices with liability separation. Many states require medical practices to be structured as PCs rather than standard LLCs or general partnerships.
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.
Allergen Immunotherapy
A treatment that desensitizes patients to specific allergens through progressively increasing doses of allergen extract administered by injection (subcutaneous) or sublingual drops/tablets. Generates separate billing for extract preparation and injection administration in addition to E&M visits. A core revenue driver in allergy-immunology private practice.
Biologic Injection Administration
Office-based administration of biologic medications (dupilumab, omalizumab, mepolizumab, etc.) for asthma, atopic dermatitis, and chronic urticaria. When the practice purchases and administers the drug (buy-and-bill), both the drug cost and administration fee are billed to the payer, generating drug margin revenue.
