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 obstetrics & gynecology contract in Colorado without knowing what else is out there. This directory shows the 182 groups they were never told about.

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

A physician who can see that there are 40 physician-owned obstetrics & gynecology groups within 50 miles walks into a contract negotiation with completely different leverage than one who assumes the hospital is the only option.

About this directory and the Colorado obstetrics & gynecology market

PGY-Final-Year is the first time the path is not drawn for you.

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

There are 182 physician-owned obstetrics & gynecology practices in Colorado, spread across 32 cities. I pulled every one of them from the NPPES NPI Registry, which is the federal database that CMS maintains for active providers. Then I filtered out anything that isn't independently operated. Hospital-employed positions, academic faculty roles, locum agencies, government clinics, they're all excluded. What's left is a clean list of practices where physicians hold actual ownership and make their own clinical decisions.

I made this because the information doesn't exist in one place anywhere else. If you're a obstetrics & gynecology physician thinking about Colorado, you'd normally have to search job boards, call recruiters, and piece together which practices are actually physician-owned versus corporate-backed. This page does that work for you. 140 practices, 32 cities, all verified through the NPPES NPI Registry. Contact them directly.

Key Terms in Physician Contracts

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.
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.
Occurrence-Based Malpractice Policy: A malpractice policy that covers any incident that occurred during the policy period, regardless of when the claim is filed. No tail insurance is required upon departure. More expensive annually than claims-made policies. Less common but eliminates departure tail risk entirely.
Claims-Made Malpractice Policy: A malpractice policy that covers claims only if both the incident and the claim filing occur while the policy is active. A tail endorsement is required at departure to cover future claims for past incidents. Most common policy type in private practice.
