How to Prepare for a CMS Exclusion Screening Audit
By Keelstar Team · Updated June 1, 2026
The short answer
Before a CMS or payer review, assemble dated screening records for a sample of employees and vendors, your written exclusion policy, re-screening schedule by risk tier, match-resolution documentation, and evidence that overdue checks trigger holds. Surveyors want proof the program runs continuously — not a folder of onboarding screenshots.
What triggers the request
CMS conditions of participation, accreditation surveys, Medicaid managed care audits, and corporate integrity agreements all reference exclusion screening. Requests may arrive as pre-survey document lists, desk reviews, or on-site interviews with HR and compliance.
Documents to prepare in advance
Do not wait for the survey letter.
- Written exclusion screening policy with list sources and frequencies
- Screening logs for employees and vendors with dates and dispositions
- Match investigation records for any potential hits
- Evidence of re-screening — not just initial hire checks
- Training records showing HR and procurement know the process
- Remediation records if an exclusion was discovered
Employee vs vendor samples
Surveyors often split requests: all employees hired since the last survey, plus contractors and volunteers in patient care or billing roles. For vendors, expect billing companies, therapy agencies, locum firms, and IT vendors with claims access — not just janitorial services.
Common survey findings
Gaps that generate deficiencies: screening only at hire, no state list checks, missing locum or agency workers, no policy, screening delegated to agencies without verification, and inability to produce logs within the requested date range.
Run an internal mock audit
Thirty days before accreditation renewal, pull a random sample of 20 employees and 20 vendors. Can you produce a complete screening history for each within an hour? If not, fix the workflow before surveyors arrive.
Day-of survey logistics
Assign one compliance owner to respond to screening requests. Use exports from your monitoring system — not ad-hoc email searches. If a record is missing, document corrective action taken and when screening was backfilled.
Frequently asked questions
- What sample size will auditors use?
- Varies by survey type — expect requests for all new hires in a period plus a sample of active staff and high-risk vendors. Have the full population exportable, not just samples you curate.
