What entity type do Anesthesiology private practices in Colorado use?

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.

Most PGY-Final-Year physicians sign their first anesthesiology contract in Colorado without knowing what else is out there. This directory shows the 300 groups they were never told about.

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.

If a recruiter tells you the hospital is the only viable anesthesiology 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 Colorado anesthesiology 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 Colorado

What you'll find here is a complete list of 196 physician-owned anesthesiology practices in Colorado, 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 300 practices across 33 cities where physicians own the entity and control the clinical direction.

Most physicians looking for anesthesiology opportunities in Colorado start with a recruiter or a job board. Both of those sources mix hospital-employed roles with genuine private practice opportunities, and they rarely disclose ownership structure upfront. This page does one thing differently: it filters for physician ownership using the federal NPPES registry. That's it. The result is 196 practices you can contact directly, without a middleman deciding what you're allowed to see.

How many Anesthesiology private practices are in Colorado?

There are 196 physician-owned anesthesiology 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 the Corporate-Acquired or MSO-Affiliated flag mean?

CRNA Supervision Ratios in Colorado Anesthesia Practices

Colorado has 10 physician-owned anesthesiology practices across 6 cities. The larger groups include Prime Anesthesia, PLLC (Denver), Anesthesia Specialists of Colorado, PLLC (Denver), and Colorado Anesthesia Services Group (Denver). U.S. Anesthesia Partners - Colorado (USAP-Color...

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 do CRNA supervision ratios affect anesthesiologist income in private practice in Colorado?

Under Medicare medical direction rules, a physician anesthesiologist can direct up to 4 CRNAs simultaneously and bill at 50% of the physician fee schedule for each case. A 1:4 ratio maximizes case volume per physician but requires strict medical direction documentation. Some groups use a 1:2 ratio for heavier physician oversight with lower volume. The ratio also affects call coverage, ask whether CRNAs take independent overnight call or always require physician backup.

Key Terms in Physician Contracts

Compensation Formula: The contractual method used to calculate physician pay. Common models include guaranteed salary, eat-what-you-kill (collections-based), salary plus production bonus (RVU or collections above a threshold), and equal-share partnership distributions. The formula directly affects income stability, upside potential, and alignment with practice goals.
Partnership Buy-In: The purchase of an ownership stake in a physician practice entity, typically offered after an associate track of 2 to 5 years. The buy-in price is calculated using business valuation, a multiple of earnings, or a formula tied to practice receivables. True equity buy-ins include voting rights and profit distributions.
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.
Medical Direction: A Medicare billing model in which a physician anesthesiologist supervises up to 4 CRNAs simultaneously, billing at 50% of the physician fee schedule for each case. Requires the physician to perform specific tasks (pre-anesthesia eval, induction, emergence, etc.) for each case. Distinct from physician personally performed cases (billed at 100%).
CRNA (Certified Registered Nurse Anesthetist): An advanced practice nurse trained in anesthesia administration. CRNAs may practice independently or under physician supervision depending on state law. In Colorado, the level of required physician oversight varies. Independent CRNA practice states have opted out of the Medicare physician supervision requirement.
