# Welcome to the DSO-PC Wiki
> An open, cited reference for forming and operating dental support organizations across the United States.
The DSO-PC Wiki is a free reference for people building or operating a **dental support organization (DSO)** in the United States. It explains the common support-company/professional-practice structure without treating it as the only lawful model, then follows the operator's work from formation and acquisitions through payer enrollment, billing, banking, and state compliance.
🦷 This wiki covers dentistry only. For management-service structures in medicine, behavioral health, med spas, veterinary, and other sectors, see the [MSO-PC Wiki](https://mso.getlemma.com).
## What this site covers
Dental ownership and control rules are unusually state-specific. Some states reserve practice ownership to dentists; others regulate proprietorship, clinical control, fees, professional-entity composition, support agreements, business managers, or non-dentist owners through different statutes and rules. There is no single national DSO blueprint. Operators need an entity and authority map, state-specific agreement terms, payer-by-payer enrollment decisions, patient-obligation tracking, and books and bank accounts that preserve the legal entities' actual roles.
The material is organized into four sections:
Guided tutorials that follow a fictional dental group from its initial structure through its first paid claim and acquisition.
Task-oriented instructions for forming a dental PC, enrolling with a payer, handling an alternate benefit, registering a DSO, or buying a practice.
Explanations of CPOD, fee-splitting, DSO economics, dental payers, entities, and financial structure.
Cited state-law pages, case law, enforcement matters, payer profiles, and EDI details.

## How we source
We prioritize primary sources: statutes, regulations, court opinions, agency materials, and payer documentation. State pages distinguish text, interpretation, and practical structuring notes; legislation gets effective dates; and uncertainty or source limitations should be stated instead of hidden behind a definitive national answer. See [How we keep this current](/reference/appendix/how-we-keep-this-current).
## Who maintains the DSO-PC Wiki
The DSO-PC Wiki is a neutral resource maintained by [Lemma](/reference/appendix/about-lemma), who builds dental-first banking for DSO groups. Lemma's banking product is documented at [docs.getlemma.com](https://docs.getlemma.com); the sibling reference for the rest of healthcare lives at [mso.getlemma.com](https://mso.getlemma.com).
See [How we keep this current](/reference/appendix/how-we-keep-this-current) for our sourcing standards and how to report an error.
