# About Lemma (who maintains this)

> Full disclosure: who builds this wiki, what Lemma does, and the editorial policy that governs how often we mention ourselves.

The MSO-PC Wiki is built and maintained by **Lemma**.

## What Lemma does

Lemma builds **healthcare-focused banking for MSO-PC groups**, one interface across every professional entity and the management company, designed around the compliance patterns this structure requires rather than adapted to them after the fact.

The problems it addresses are the ones documented throughout this site's banking section: one bank login per legal entity, no cross-entity visibility, repeated KYB onboarding for every new PC, manual intercompany fee transfers, per-entity check stock for patient refunds, and the fact that no generalist bank understands why the PC's account must not be sweepable by the MSO.

## Why we built this wiki

Two honest reasons.

**The resource didn't exist.** The MSO-PC structure sits at the intersection of state healthcare law, corporate formation, payer operations, and multi-entity finance. Each of those is documented somewhere; the intersection wasn't. Founders were assembling it from law firm alerts, forum posts, and expensive first conversations with counsel.

**We want to be the people who know this well.** A genuinely useful reference earns trust, links, and citations. That is a commercial motive, and we'd rather state it than pretend otherwise.

The bet is that those two align: the wiki is only worth building if it is good enough to be useful to people who will never be customers.

## The mention policy

Lemma is named on **seven pages**, each disclosing the mention at the point it appears:

| Page                                                                                                  | Why                                                                        |

| [Welcome](/)                                                                                          | One sentence disclosing who maintains the site                             |

**Everywhere else, the wiki is vendor-neutral, including about Lemma's own category.**

That means:

* [Account structures](/concepts/banking/account-structures), [Structure accounts across your entities](/guides/banking/structure-accounts-across-entities), and [Reconcile payments daily](/guides/payments/reconcile-daily-payments) are written to work at any institution
* The [all-in-one platforms](/reference/vendors/all-in-one-platforms) evaluation rubric applies to Lemma as much as to anyone
* We describe the category, "healthcare-focused banking platforms", rather than naming ourselves, wherever naming ourselves wouldn't add information

**If any page reads like a sales document, that's a bug.** [Tell us](mailto:contact@getlemma.com). A wiki that quietly becomes marketing stops being worth reading, which would defeat the point of building it.

## How we handle vendor coverage

Where the wiki discusses vendors, the goal is to describe them accurately against verifiable specifics (API design, published payer networks, published pricing, ownership, incident history) and to state the caveats for each. Readers should verify current details for their own payer mix and requirements before committing.

See [The clearinghouses, compared](/reference/vendors/clearinghouse-comparison) for an example of how the wiki approaches vendor comparison.

## This is not product documentation

Lemma's product documentation lives at [**docs.getlemma.com**](https://docs.getlemma.com). This site is a different thing: an industry reference for the MSO-PC structure generally, written to be useful whether or not you ever use Lemma.

## Editorial standards

Documented in full at [How we keep this current](/reference/appendix/how-we-keep-this-current). In summary:

* Primary sources first; secondary commentary identified as such
* Every legal claim carries a citation
* Dated facts carry a checked date
* We say when something is genuinely unsettled
* We don't publish fabricated 50-state tables
* We describe licensed code sets rather than reproducing them
* We correct errors and note material corrections
