What entity type do Allergy & Immunology private practices in Pennsylvania use?

Physician-Owned Allergy & Immunology Practices in Pennsylvania

Q: What does the Corporate-Acquired or MSO-Affiliated flag mean?

The Corporate-Acquired flag indicates the practice was historically physician-owned but has since been acquired by a corporate entity such as Optum or UnitedHealth Group. The MSO-Affiliated flag indicates the practice participates in a Management Services Organization, which provides administrative infrastructure while physicians retain ownership at the practice level. These flags help physicians understand the ownership structure before reaching out.

About this directory and the Pennsylvania allergy & immunology market

Step 1. Step 2. Match. Boards. Then what?

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.

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 Pennsylvania

This directory covers 151 independently operated allergy & immunology practices in Pennsylvania. The data comes from two sources: the NPPES NPI Registry (the federal provider database maintained by CMS) and DataForSEO business listings for contact details and descriptions. I've excluded every practice that doesn't qualify as physician-owned. That means hospital-employed positions, academic roles, and corporate medical groups are filtered out. What remains is 232 practices across 55 cities.

The distinction between physician-owned and corporate-owned isn't just a label. It determines how a practice makes decisions about staffing, compensation, patient volume, and reinvestment. This directory exists because no other resource separates physician-owned allergy & immunology practices in Pennsylvania from everything else. Every listing has an active NPI, is independently operated, and represents a real opportunity where a physician sets the clinical direction. Not an MBA. Not an investor. A doctor.

Frequently asked questions about allergy & immunology in Pennsylvania

How many Allergy & Immunology private practices are in Pennsylvania?

There are 151 physician-owned allergy & immunology private practices in Pennsylvania, 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 Pennsylvania

Pennsylvania has 12 physician-owned allergy & immunology practices across 8 cities. The larger groups include Asthma Allergy & Pulmonary Associates (Pittsburgh), Allegheny Asthma & Allergy (Pittsburgh), and Center for Asthma & Allergic Diseases (Pittsburgh).

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 Pennsylvania?

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

Without-Cause Termination: A contract clause that allows either party to end the employment agreement without stating a reason, typically with 60 to 120 days written notice. The notice period, post-termination obligations (non-compete activation, tail insurance responsibility), and severance terms are negotiable. Shorter notice periods favor the employer.
Call Coverage: The obligation to provide after-hours or weekend coverage for patient emergencies. Contracts should specify call frequency (1 in 4, 1 in 6, etc.), whether call is compensated separately, and whether the physician takes call from home or in-house. Unrestricted call obligations are a common source of physician burnout.
Credentialing: The process by which hospitals and insurance companies verify a physician's education, training, board certification, licensure, and malpractice history before granting privileges or network participation. Credentialing typically takes 60 to 120 days and must be completed before a physician can bill patients under a new practice or facility.
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.
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.
