Allergy & Immunology Private Practices in Colorado (88 Verified Groups) | Daniel Aragón

There are 88 physician-owned allergy & immunology practices in Colorado, vetted against the NPPES NPI Registry. Hospital-employed, government, and academic positions are excluded.

Every group physicians still own.

Physician-Owned Allergy & Immunology Groups in Colorado

Before you accept a hospital offer in Colorado, see how many physician-owned allergy & immunology groups already exist. The answer is 147, and it changes everything you can ask for in negotiation.

MCAT. STEPs. Match. ABIM. Each one was a milestone someone else designed. You hit them in order, on time, and the path kept going.

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.

NOT INCLUDED IN THIS DIRECTORY

Hospital-employed, government-operated, and academic positions are excluded. These are not independent private practices:

  • National Jewish Health Allergy and Immunology
  • Children's Hospital Colorado Allergy and Immunology

About this directory and the Colorado 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.

What this directory does is hand you the page you were missing. Every physician-owned allergy & immunology group in Colorado, in one place, so the first contract you sign is not the only contract you ever saw.

What other resources point to in Colorado

This directory covers 88 independently operated allergy & immunology practices in Colorado. 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 147 practices across 25 cities.

Here's why I built this. When I was looking at private practice opportunities, I couldn't find a single resource that separated physician-owned practices from everything else. Job boards don't do it. Recruiter databases don't do it. So I built it from the NPPES registry. Whether you're finishing training, thinking about a lateral move, or exploring partnership-track positions in Colorado, this gives you a filtered starting point that actually tells you who owns what.

The Colorado allergy & immunology market in detail

Colorado's physician-owned allergy & immunology directory lists 88 practice locations across 24 cities. The largest groups include Aspire Allergy & Sinus (4 locations), Jeffrey Rumbyrt, MD (3 locations), and William Newman, MD (3 locations).

None of the allergy & immunology practices listed in Colorado carry a PE-Backed or Corporate-Acquired flag. All listings in this directory are physician-owned independent practices verified through NPPES.

Practices span 24 cities including Arvada, Aurora, Boulder, and Brighton.

Frequently asked questions about allergy & immunology in Colorado

How many Allergy & Immunology private practices are in Colorado?

There are 88 physician-owned allergy & immunology private practices in Colorado, 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 Colorado

Colorado has 42 physician-owned allergy & immunology practices across 18 cities. The larger groups include Colorado Allergy & Asthma Centers, P.C. (Denver), Denver Allergy & Asthma Associates (Denver), and Allergy & Asthma Care and Prevention Center (Denver). Aspire Allergy & Sin...

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 Colorado?

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

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.
Malpractice Insurance
Professional liability coverage that protects physicians against claims of medical negligence. Two main types exist: claims-made (covers claims only if both the incident and filing occur during the active policy) and occurrence-based (covers any incident during the policy period, regardless of when the claim is filed). Premium costs vary dramatically by specialty and state.
Ancillary Revenue
Income generated by a medical practice from services beyond physician office visits. Common sources include in-office imaging, laboratory testing, physical therapy, infusion services, and dispensing. Ancillary revenue can account for 20 to 40 percent of total practice revenue in procedure-heavy specialties.
NPPES (National Plan and Provider Enumeration System)
The federal registry maintained by CMS that assigns and tracks NPIs for all U.S. healthcare providers. NPPES data is publicly searchable and includes provider name, practice address, taxonomy codes, and enumeration date.
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.
