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. The result is not one 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. This wiki documents all of it, at four levels of depth: **Learn.** Guided, sequential tutorials with a guaranteed outcome. Follow a fictional dental group from idea to first paid claim to first acquisition. **Do.** Task recipes for a competent reader with a specific goal: form a dental PC, enroll with Delta, work a downgrade, register a DSO, buy a practice. **Understand.** The mental models and the *why*: the CPOD doctrine, fee-splitting, DSO economics, the dental payer landscape, where DSO profit actually lives. **Look up.** Cited: 51 state CPOD pages, the dental case-law canon, the enforcement record, dental payer profiles, CDT and 837D anatomy. ## Who this is for | If you are… | Start at | | -------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------- | | A founder building a dental group | [What is a DSO?](/start/what-is-a-dso) | | A dentist being asked to own a "friendly PC" | [The friendly PC, explained](/concepts/model/the-friendly-pc) | | A dentist selling to or joining a DSO | [DSO economics](/concepts/finance/dso-economics) — what the deal structures actually pay | | An operator or biller doing the work day to day | [Guides](/guides/billing/run-the-dental-billing-cycle) and [Reference](/reference/edi/denial-code-playbook) | | An operator preparing for an acquisition or legal review | [Dental transaction issue-spotter](/reference/legal/dental-transaction-issue-spotter) and [DSO laws by state](/reference/legal/dso-laws-by-state) | ## 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. ## Next The five-minute orientation: two entities, one business, and the century-old doctrine that splits them.
