Preparing for an Unannounced Accreditation Survey

Accreditation surveys of DME suppliers are unannounced by rule, not by custom. The CY2026 home health final rule (CMS-1828-F, 90 FR 55342) wrote a definition into 42 CFR 424.58(b): an unannounced survey is one "conducted without any prior notice of any type (through any means of communication or forum) to the DMEPOS supplier to be surveyed such that the supplier does not expect the survey until the surveyors arrive," and the accrediting organization "schedules its surveys so that DMEPOS suppliers cannot predict when they will be performed." CMS explained why in the rule's preamble: so that "a non-compliant supplier cannot use prior notice of a survey to remedy its deficiencies solely to pass the survey."

The same rule made reaccreditation annual (424.57(c)(24)). The only workable preparation is a business that is survey-ready on an ordinary Tuesday.

What are surveyors measuring you against?

The CMS DMEPOS Quality Standards (final, effective August 12, 2024), which every approved accrediting organization applies. Section I covers business services for all suppliers; Section II covers product-specific services; Appendices A, B and C add requirements for respiratory equipment, wheelchairs and power mobility, and custom orthotics, prosthetics and related items. Your accreditor's own standards are built on these, and CMS requires each organization to show a crosswalk to them.

Which business requirements are easiest to fail?

• Licenses on display. The supplier "shall have a physical location and display all licenses, certificates, and permits to operate" in an area accessible to customers.
• A named compliance lead. Business practices to prevent fraud, waste and abuse, including written standards of conduct and "one or more individuals in leadership positions to address compliance issues."
• Personnel files. Job descriptions with qualifications and training, and verified copies of "licenses, registrations, certifications, and competencies for personnel who provide beneficiary services." Technical staff must be competent to deliver, set up and train.
• Complaint timelines. Notify the beneficiary within 5 calendar days that a complaint was received and is being investigated, and give written results within 14 calendar days. Keep the complaint, the investigation and the response.
• Orders you cannot fill. If you cannot or will not provide prescribed equipment, notify the prescriber "promptly within 5 calendar days."
• A performance management plan that measures, at minimum, beneficiary satisfaction and complaints, timeliness of responses, access, billing and coding error frequency, and adverse events.
• Incident investigation. Start within 24 hours when an incident involving your equipment results in hospitalization or death, and within 72 hours otherwise.
• An emergency and disaster contingency plan, or arrangements with alternative suppliers.
• Product verification. Before delivery, verify and document that products are not adulterated, counterfeit or misbranded and are labeled for their distribution channel.

What will surveyors look for in patient records?

Real ones. The Quality Standards say: "A minimum of 5 patient medical records must be reviewed as part of the accreditation survey," and those records "shouldn't include" mock files, fictional patients, simulated documentation or templates. "Non-Medicare patient records can be used during the initial accreditation survey. Medicare patient records must be reviewed for reaccreditation."

That last line matters for a new supplier. You need at least five genuine patients, served under your policies, before the initial survey can succeed. Plan cash-pay or commercial patients into the months before the survey.

In each record, surveyors look for what Section II and the consumer services standards require:

• the prescription, any certificates of medical necessity and pertinent prescriber documentation, kept unaltered;
• the make and model or other identifier of non-custom equipment delivered;
• proof that the beneficiary received the item, and of written or pictorial and oral instructions on use, maintenance, infection control and hazards;
• for initial items delivered by mail order, documentation that the beneficiary or caregiver "has received training and written instructions";
• rent-or-purchase information where it applies, and contact numbers for service, repairs and after-hours access;
• follow-up consistent with the equipment and the prescriber's recommendations.

Do some product lines add their own checks?

Yes. Respiratory suppliers must provide services "24 hours a day, 7 days a week as needed" and follow named American Association for Respiratory Care practice guidelines for oxygen, home ventilation and related equipment (Appendix A). Suppliers of complex rehabilitative wheelchairs must employ, as a W-2 employee, at least one qualified rehabilitative technology supplier per location with one of the listed credentials, backed by trained technicians with at least 10 hours of continuing education a year (Appendix B). Custom O&P has its own fitting and facility requirements (Appendix C).

How does a survey day usually unfold?

CMS describes the process in three stages: pre-application, application, and an on-site survey at which the accrediting organization "conducts an unannounced on-site survey" and then "determines accreditation based on your submitted data and on-site survey results" (MLN905710). Expect a walk-through of the location, interviews with staff on duty, a review of policies against practice, and the patient-record sample. Deficiencies lead to a plan of correction or a follow-up survey under the organization's procedures, which CMS now requires each accreditor to define and report.

What does a survey-ready routine look like?

1. Weekly: close out complaints inside the 5- and 14-day windows; file proof of delivery and training for every delivery.
2. Monthly: pull five random patient files and check them against the record list above; update the performance management log; confirm licenses and insurance certificates on the wall are current.
3. Quarterly: refresh staff competency checklists; test the emergency plan; review the product list against your accreditation scope and the 855S.
4. Before your window opens: run a full mock survey with someone who did not write the files.
5. Always: make sure whoever is on duty knows where the policy manual, complaint log and personnel files are, and how to reach the owner.

The policy manual itself is covered in what a DMEPOS policy and procedure manual has to cover, and survey timing in annual reaccreditation.

Who can run a mock survey for you?

Not necessarily your accreditor. Under 42 CFR 424.58(m), an accrediting organization may not provide consulting, which the rule defines to include a mock survey, to a new supplier before its initial survey or to one of its suppliers within 6 months before its next reaccreditation survey. An independent consultant is outside that rule. Our Accreditation Readiness service ($2,495) includes a mock unannounced survey before your first survey, and Annual Survey Readiness ($1,200 per year) repeats it before each annual window (see pricing). The accreditation decision belongs to the accrediting organization alone.
