MUSTER.
Muster Roll

The screening query is the commodity.

A muster roll is the official list of who is in the unit, and whether each person is present and fit to serve. Anyone can run a name against the LEIE. What an organization usually cannot do is prove that nobody was missing from the list it ran. That proof is the service.

Where the finding comes from

Screening rarely fails because a list went unchecked. It fails because the covered population was never fully assembled — a staffing agency's roster, a vendor's managing employees, a volunteer nobody thought to include. The gap is invisible from inside the screening tool, and it is the first thing a surveyor reaches for.

The roster is built from four independent sources

Onboarding constructs the covered-population roster and reconciles these against each other. The discrepancies between them are the deliverable.

Payroll register

Every employee, without regard to role or duties. The baseline the other three are measured against.

Accounts payable vendor master

Every entity paid. Owners and managing employees fall within the screened population and are rarely revisited after contracting.

Contract register

Contractors, locums, agency staff, and subrecipients. Frequently held in a spreadsheet, sometimes in no system at all.

Governance and volunteer records

Board members, volunteers, and students, per the scope the client elects. They appear in no payroll run and are the most commonly omitted group.

The reconciliation is the product. Ongoing completeness is maintained through monthly roster deltas and confirmed by a quarterly reconciliation against payroll and the vendor master. An organization that has never reconciled these four typically finds people it was not screening — a finding better received from us than from a surveyor.

Start here: the Roster Baseline Assessment

A one-time, fixed-fee engagement answering a single question — who are we not screening? It stands alone and obligates you to nothing afterward.

We reconcile the four sources against your current screening roster and hand you the difference, name by name.

Most organizations expect a handful of gaps. What surfaces is usually a category — an entire class of people nobody had assigned to anyone. Contracted therapists. A staffing agency's roster. The owners of a vendor that has billed you for three years.

Scoped deliberately so it can be done once, understood in a single meeting, and acted on without a standing engagement.

What you receive
  • Reconciled roster across payroll, vendor master, contracts, and governance records
  • Named list of individuals and entities absent from current screening
  • Gap categories, with the system-of-record failure behind each
  • Covered-population definition you can adopt as policy
  • Ownership map: who maintains which source, going forward
  • Findings memo suitable for your compliance committee or board

The monthly cycle

You transmit roster changes. We run the sources, resolve every result, and deliver the evidence. You act on anything confirmed.

Roster

Roster maintenance

Hires, terminations, new contractors, and new vendors reconciled into the covered population each cycle, with additions flagged for pre-engagement screening timing.

Screening

All elected sources

The OIG List of Excluded Individuals and Entities, SAM exclusion records, the CMS Preclusion List, and the Medicaid exclusion and ineligible-provider list for every state you elect. Additional lists on request.

On demand

Pre-engagement screening

Handled as a committed-turnaround transaction, not folded into the monthly rhythm. The failure mode here is someone starting work before the check clears, and a monthly cycle cannot prevent that.

Resolution

Every result resolved

No match, confirmed match, or unresolved — each with the identifiers compared and the basis recorded. A confirmed match is escalated in writing to your designated contact the same day, because exposure accrues for every item or service furnished while the person remains in a billable role. Nothing is silently closed.

Evidence

Monthly evidence package

Dated results, resolution records, and an exception report — delivered to you each cycle. You hold a copy of every package, so we are never the system of record for your own compliance evidence.

Quarterly

Reconciliation and annual summary

Quarterly reconciliation of the roster against payroll and the vendor master, and an annual summary written for a survey binder or a board report rather than for a systems administrator.

Tiers

Priced on a one-time onboarding fee, a monthly base, and a per-covered-individual rate banded by roster size.

Basic

The monthly cycle and reporting. Roster maintenance stays with you; quarterly reconciliation is available separately.

Managed

Adds roster maintenance, quarterly reconciliation, and the annual summary. The tier most organizations need, because the roster is the part that drifts.

Managed + AuditLimited

Adds an independent annual test of the screening record. Available only where Muster does not also hold your designated officer role — see below.

Boundaries we hold

Stated here rather than buried in an engagement letter, because they are the reason to trust the work.

At most two of three roles

For any one client, Muster will hold no more than two of: author of the compliance policy, designated compliance or privacy officer, operator of the screening service. Holding all three leaves nobody to check the work. The election is made at engagement and recorded in writing.

You act; we inform and document

Out of scope by design: employment decisions, credentialing and privileging, payer enrollment, overpayment quantification, self-disclosure, and legal advice on the effect of any particular exclusion. We document what we compared and what we concluded.

Workforce data, never patient data

Rosters are workforce records. We do not accept patient data into this workflow for any reason, and we do not request full Social Security numbers as a matter of course — only the identifier needed to resolve a specific match, and not retained past resolution.

What we warrant. That we ran the elected sources on schedule and resolved every result to a documented disposition. We do not warrant the completeness or currency of third-party government databases, and nothing here is legal advice.

Who this is for
