# ASC survey readiness: how to be ready every day

> Every CMS or state survey of an ambulatory surgery center is unannounced. Surveyors watch at least one surgical case, tour the building, interview people and review records. In the first hours they ask for surgery lists, transfers, policies and QAPI documents. Keep those records current every day.

## Key facts

- **Notice:** All CMS and state ASC surveys are unannounced
- **Standard team:** Usually two health surveyors (at least one RN) and one Life Safety Code surveyor, about 2 days on site

- **Record sample:** At least 20 closed records if over 50 cases a month, 10 below that; always deaths and hospital transfers
- **Day-one lists:** Surgeries from the past 6 months, transfers or deaths from the past year; usually due in 1 to 2 hours
- **After the survey:** Form CMS-2567 within 10 working days; plan of correction within 10 calendar days of receipt
- **Deemed ASCs:** Surveyed by their accreditor; CMS validates a sample

- **Citation:** 42 CFR Part 416, Subparts B and C; CMS State Operations Manual, Appendix L
- **Authority:** CMS and state survey agencies; CMS-approved accrediting organizations
- **Applies to:** Medicare-certified ambulatory surgical centers surveyed by a state agency, ASCs accredited by a CMS-approved organization for deemed status

## Who surveys an ASC?

The state survey agency surveys a non-deemed ASC for CMS. If a national accreditor gives CMS reasonable assurance, CMS may deem its ASCs compliant with the Conditions for Coverage (the federal ASC rules). The accreditor then surveys them, and CMS samples them for validation.

| Survey type | Who conducts it | Scope |
| --- | --- | --- |
| Initial or recertification | State survey agency (non-deemed ASCs) | All Conditions for Coverage, including Life Safety Code |
| Accreditation survey | The accrediting organization (deemed ASCs) | The accreditor's standards, which CMS found meet its conditions |
| Validation | State agency, when CMS selects a deemed ASC. Finished within 60 days after the accreditor's survey | All Conditions for Coverage |
| Complaint or revisit | State agency, or the CMS Location for deemed ASCs | Conditions tied to the complaint or to earlier deficiencies |

Refusing surveyors access can lead to exclusion from federal health care programs. See [deemed status](https://incidentkit.ai/glossary/deemed-status) and [conditions for coverage](https://incidentkit.ai/glossary/conditions-for-coverage).

## What do surveyors look at?

Surveyors use observation, interviews and document review. They pick at least one surgical case to watch, preferably on day one. They may follow the patient from pre-operative assessment to recovery or discharge. They also tour the building and complete a CMS infection control tool.

Interviews use open questions, such as what a staff member would do if they smelled smoke. A written policy alone never proves compliance. Surveyors check that daily practice matches it, and sample closed records from the past six months.

## What will surveyors ask for on day one?

The team asks for these at the entrance conference. CMS says an ASC should usually produce the case lists within 1 to 2 hours.

- Today's scheduled surgeries (and tomorrow's for a 2-day survey): patient name, age, procedure, surgeon.
- All surgeries from the past 6 months.
- All cases in the past year where a patient was transferred to a hospital or died.
- Names of the director of nursing, active medical staff, allied health professionals and other patient care staff.
- An organizational chart and a floor plan.
- Selected policies, procedures and personnel records.
- Written infection control and ongoing quality self-assessment programs.
- A list of contracted services, and a private room with a telephone.

## What should be ready for each condition?

This is our reading of what surveyors review under each condition. It is not a CMS form.

| Area | 42 CFR | Have ready |
| --- | --- | --- |
| Governing body and management | 416.41 | Current policy manuals, outside service contracts, organizational chart |
| Surgical services | 416.42 | Pre-operative assessment and risk documentation, anesthesia assessment, informed consent in each record |
| Quality assessment and performance improvement | 416.43 | Indicators, adverse event log, hospital transfers, cause analyses, projects with reasons and results, proof staff know prevention strategies |
| Environment | 416.44 | Maintenance and equipment records, any Life Safety Code waivers in effect |
| Medical staff | 416.45 | Privileging and credentialing files that follow your policy and state law |
| Nursing service | 416.46 | Personnel files showing education, training, licensure and credentials |
| Medical records | 416.47 | H&P and update, consent, operative findings and complications, signed medication orders, post-surgical assessment, transfer reason, discharge notes, signed discharge order |
| Infection control | 416.51 | Program documents, surveillance, and visible hand hygiene and sterilization practice |
| Emergency preparedness | 416.54 | Your emergency preparedness program (surveyed under Appendix Z) |

## How do surveyors test your QAPI program?

Under 42 CFR 416.43 an ASC must track adverse patient events, examine their causes, make improvements and make them last. Surveyors ask what data you collect, who analyzes it, and how you find causes. CMS gives an example: blaming a staff member for a medication error and firing them is not a systems approach. A good analysis asks how medications were stored, whether orders were clear and whether others made similar errors.

They also ask for examples where data led to a change, and proof it held. See [ASC QAPI requirements](https://incidentkit.ai/compliance/cms-qapi/ambulatory-surgery-centers).

## How do you stay ready every day?

1. **Keep the case lists current** Produce six months of surgeries and a year of transfers and deaths within an hour or two.
2. **Make every adverse event traceable** Each has a record, a cause analysis, an action and a check that the fix held.
3. **Walk the building like a surveyor** Check medication storage, expiration dates, room cleaning between cases and patient identity checks.
4. **Ask staff open questions** What do you do before surgery starts? What would you do if you saw a breach in sterile technique?
5. **Rehearse the entrance** Decide who greets the team and who pulls records if the surgeon is in a case. Surveyors wait up to about 15 minutes for leadership.
6. **Run the self-check** Use the [survey readiness check](https://incidentkit.ai/tools/survey-readiness-check) and the [survey and accreditation readiness guide](https://incidentkit.ai/guides/survey-and-accreditation-readiness).

## What happens after the survey?

At the exit conference surveyors share preliminary findings, without tag numbers or ratings. The state prepares Form CMS-2567 within 10 working days. If it lists deficiencies (findings of noncompliance), send a written [plan of correction](https://incidentkit.ai/compliance/survey-readiness/plan-of-correction) within 10 calendar days of receiving it. CMS makes the 2567 public no later than 90 calendar days after the survey.

Surveyors cite all noncompliance they find, even if you fix it on site. The one exception is a problem the ASC found and fixed before the survey. The fix must be effective, and nothing else may show current noncompliance. See the [CMS-2567 glossary entry](https://incidentkit.ai/glossary/cms-2567).

## How do accreditor surveys differ?

Accreditors use their own standards and cycles. AAAHC describes a 1,095-day accreditation cycle and a Medicare deemed status program. Its on-site review is peer-based and educational. Joint Commission says CMS-deemed surveys are unannounced. It lists ASCs not using accreditation for deemed status among those that get 7 days' notice. A deemed ASC can still face a CMS validation survey. See [AAAHC](https://incidentkit.ai/compliance/accreditation/aaahc), [Joint Commission](https://incidentkit.ai/compliance/accreditation/joint-commission) and [AAAHC vs Joint Commission for ASCs](https://incidentkit.ai/blog/aaahc-vs-joint-commission-for-ascs).

## What the rule asks for, and how IncidentKit supports it

| Requirement | IncidentKit |
| --- | --- |
| Track adverse patient events, examine causes, sustain improvements (42 CFR 416.43) | Each incident flows into an investigation, then a corrective action with an owner, due date, evidence and effectiveness check. Nothing closes until verified. |
| Produce case lists, hospital transfers and deaths on request | Filter the incident log by type and date. Compliance packets build a survey packet from it. |
| Show that a pre-survey fix addressed the systemic cause and held | The audit trail and effectiveness check give dated evidence of what changed and whether it worked. |
| QAPI data and improvement project documentation | Analytics cluster incidents by location, shift, equipment and cause. Compliance packets include QAPI summaries. |
| Policies, personnel files, maintenance records and the rest of the survey binder | Not an IncidentKit function. IncidentKit runs alongside your EHR, HRIS and CMMS and does not replace them. |

## Frequently asked questions

### Is an ASC survey announced?

No. CMS directs that all ASC surveys be unannounced. Surveyors arrive in business hours and hold an entrance conference. Joint Commission also surveys deemed ASCs without notice. Some accreditation surveys of non-deemed ASCs get notice, such as 7 days at Joint Commission, so check your accreditor.

### Can surveyors watch surgery?

Yes, with the patient's permission. CMS requires surveyors to observe at least one surgical case, and the patient's consent must be added to the informed consent. The operating physician's consent is not needed. An ASC cannot require signed documents or proof of vaccination. Denying access is a deficiency.

### What if we fix a problem during the survey?

Surveyors still cite it. All noted noncompliance is cited, even if fixed on site. The exception is a problem the ASC found and fixed before the survey. The ASC needs evidence the fix addressed the causes and worked, and nothing else may show current noncompliance.

### How many medical records will surveyors review?

At least 20 closed records if the ASC does more than 50 cases a month. At least 10 below that. Records come from the past six months. The sample includes Medicare and other patients, and all deaths and hospital transfers. The team may review more.

### What shows surveyors that our QAPI program works?

Data, examples and proof. Surveyors ask what quality and adverse event data you collect, who analyzes it, and how you find root causes, not just staff error. They ask for cases where data led to lasting improvement, and how staff learn prevention strategies. Indicators should cover at least hospital transfers and infection control.
