What CMS and Joint Commission Surveyors Expect From the ISO That Maintains a Hospital's Equipment
Short answer: CMS and Joint Commission survey the hospital, not its service vendors. The hospital has to show an accurate equipment inventory, and maintenance done to the manufacturer's recommendations or its own documented AEM program, on schedule, by qualified people. CMS says that applies to contractors as well as employees. When an ISO maintains the equipment, most of that evidence is the ISO's records. A shop that can hand over complete PM records, post-repair test results and technician qualifications the same day is the shop hospitals keep.
This guide is for owners and service managers at independent biomed shops. It sets out what the rules say (with links to the primary sources), what changed at Joint Commission in 2026, and a checklist of what to have ready when a customer calls to say "the surveyors are here."
Who is actually being surveyed?
The hospital. Hospitals that take Medicare must meet the CMS Conditions of Participation. The physical environment condition says: "Facilities, supplies, and equipment must be maintained to ensure an acceptable level of safety and quality" (42 CFR 482.41(d)(2)). Critical access hospitals have a matching requirement at 42 CFR 485.623(b)(1). Most hospitals show they meet these conditions through an accrediting organization such as Joint Commission or DNV, or through a state survey.
Nobody surveys your shop directly. But when a surveyor pulls the maintenance history for an infusion pump you service, they're reading your work.
What does CMS require for medical equipment maintenance?
CMS set out its expectations in survey memo S&C 14-07-Hospital (December 2013) and the critical access hospital version, S&C 14-41-CAH (August 2014). The guidance has since been folded into the State Operations Manual. In short:
- The default is the manufacturer's recommendations. When a hospital follows them, it has to keep documentation of those recommendations and of the maintenance actually done.
- A hospital may use different activities or intervals through a documented alternate equipment management (AEM) program, based on a risk assessment and generally accepted standards of practice. CMS gives ANSI/AAMI EQ56 as an example. The hospital must then "adhere strictly" to the activities and frequencies it sets.
- The hospital must identify critical equipment in its AEM program: equipment where failure risks serious injury or death. Surveyors are told to focus their AEM review there.
- All equipment must be inspected and tested for performance and safety before initial use and after major repairs or upgrades.
- The hospital must evaluate whether its AEM program works: how malfunctions are found and investigated, whether a failure was caused by the AEM strategy, how unsafe equipment is taken out of service, and how performance data changes the program.
Which equipment can't go on an AEM program?
| Equipment | Rule under CMS guidance | What it means for your shop |
|---|---|---|
| Imaging and radiologic equipment (diagnostic or therapeutic) | Must be maintained per manufacturer's recommendations | Use the OEM procedure and interval on CT, MRI, x-ray and similar systems, and keep a copy of the source |
| Medical lasers | Must be maintained per manufacturer's recommendations | FDA requires laser manufacturers to provide the maintenance schedule and service instructions to purchasers, and at cost to other parties who request them. Ask for them. |
| New equipment without enough maintenance history | Manufacturer's recommendations until enough history exists | Your incoming inspection and PM records are the history the hospital will need later |
| Equipment where other federal or state law, the CoPs, or the Life Safety Code set requirements | Those requirements apply | Check state rules for the equipment you service |
Most shops miss this: CMS says the maintenance history needed to justify moving equipment into an AEM program can come from the hospital's own records or its contractor's. Clean, complete service records from your shop can help a customer build a defensible AEM program, and that's worth mentioning when you bid.
Does it matter that the work was done by a contractor?
Yes, and here the paperwork lands on you. Under the CMS guidance, the people deciding which equipment goes into an AEM program, doing the risk assessments, managing the program and doing the maintenance must be qualified, "whether employees or contractors." The hospital "must be able to demonstrate how they assure contracted personnel making such decisions are qualified." CMS notes that a clinical or biomedical technician or engineer would generally be considered qualified for medical equipment, and that highly specialized or complex equipment may need specialized training.
In practice, keep a qualifications file for every technician and send it to customers without being asked: training records, OEM service school certificates for the systems they work on, and professional certifications such as AAMI's CBET where they hold them.
What changed at Joint Commission in 2026?
If your contracts, SOPs or report templates cite EC.02.04.01 or EC.02.04.03, those numbers are out of date.
- New chapter. From January 1, 2026, Joint Commission merged its Environment of Care and Life Safety chapters into one Physical Environment chapter for hospitals and critical access hospitals. It renumbered the standards and aligned them more closely with the CMS Conditions of Participation (ASHE).
- Fewer itemized EPs, same work. Medical equipment testing and inspections are no longer spelled out as separate elements of performance, but they still have to be done and can still be cited (CompQuail, November 2025).
- No separate written medical equipment management plan is required any more, except for ambulatory care organizations (HFM).
- Documentation follows the manufacturer or the AEM program. Revised elements effective March 1, 2026 say inspection and testing is documented per the applicable NFPA standard where one applies, and otherwise per the manufacturer's instructions or an AEM program (HFM, February 2026).
For reference, the old hospital standard EC.02.04.03 expected a 100% completion rate for equipment maintained to manufacturers' recommendations and for high-risk equipment in an AEM program. Ask each customer which current Physical Environment elements they're surveyed against, and check the wording in their copy of the accreditation manual. Don't rely on a vendor blog, ours included.
What should an ISO be able to hand over?
| What the hospital has to show | What your shop should be able to produce |
|---|---|
| An inventory of the equipment it maintains | Current asset list per facility: asset tag, manufacturer, model, serial, location, high-risk flag, and interval source (manufacturer or AEM) |
| Maintenance done to manufacturer recommendations | The procedure and interval used for each device type, and the completed PM records with results and readings |
| Strict adherence to AEM frequencies | Completed PMs against the customer's AEM intervals, with dates showing each one was done on time |
| Testing before first use and after major repair | Incoming inspection records for new equipment, and post-repair performance and electrical safety test results on the repair work order |
| Qualified personnel, including contractors | A qualifications file per technician |
| An AEM program that is monitored for effectiveness | Repair history by device and failure type, so the customer can see whether failures relate to the AEM strategy |
| Unsafe equipment removed from service | Records of devices tagged out, why, when, and who at the facility was told |
| Maintenance that is up to date | A monthly PM completion report, high-risk equipment shown separately, with a could-not-locate list |
Survey-week checklist for your shop
When a customer tells you a survey is coming, or that surveyors are on site, aim to send all of this the same day:
- The current equipment inventory for that facility, with high-risk devices flagged
- PM completion reports for the last 12 months, with high-risk equipment on its own line
- The open PM list and an expected completion date for each item
- The could-not-locate list and what was done about each device
- Service reports for any device the customer names, with test results and signatures
- Post-repair test records for recent repairs on high-risk equipment
- Calibration certificates for the test equipment your technicians used: ESA analyzer, defib analyzer, infusion device analyzer, SpO2 and NIBP simulators
- Technician qualifications files
- The PM procedures and intervals you used, and the source of each (manufacturer or the customer's AEM program)
- A named contact at your shop who can answer a surveyor's question that day
If producing this list takes a week of digging through folders and spreadsheets, fix that first. A customer won't wait a week during a survey.
Where Bravio fits
Bravio is CMMS and field service software for independent biomed shops. It keeps one record per device across every customer, generates PMs from each device's interval, and records readings, photos and signatures on an offline technician app. The closed job becomes a branded, ISO 13485-aligned service report with both signatures and a full audit trail. That makes the records in the table above quick to pull. Bravio helps you produce and keep those records. It does not make your shop or your customer compliant: that judgement belongs to the hospital and its surveyor.

Frequently asked questions
Does Joint Commission survey independent service organizations directly?
No. Joint Commission and CMS survey the hospital. Work done by contractors, including independent service organizations, is evaluated through the hospital's equipment records, so the ISO's service reports, PM records and technician qualifications are often what the surveyor ends up reading.
Can an ISO put a hospital's equipment on an AEM program?
An ISO's qualified technicians or engineers can do the risk assessment and recommend which equipment goes into the program: CMS says these decisions must be made by qualified personnel, whether employees or contractors. The AEM program itself belongs to the hospital, which must document it and adhere strictly to the frequencies it sets.
Can imaging equipment or medical lasers be on an AEM program?
No. Under CMS guidance, imaging and radiologic equipment and medical lasers must be maintained according to the manufacturer's recommendations. New equipment without enough maintenance history must also follow the manufacturer until enough history exists.
Are Joint Commission standards EC.02.04.01 and EC.02.04.03 still current?
Not under those numbers. From January 1, 2026, Joint Commission merged its Environment of Care and Life Safety chapters into a single Physical Environment chapter for hospitals and critical access hospitals and renumbered the standards. Medical equipment maintenance is still required and surveyed; check the current element numbers in the hospital's accreditation manual.
What records should an ISO keep for a hospital customer's survey?
A current equipment inventory with high-risk devices flagged, completed PM records against the manufacturer or AEM interval, post-repair and incoming test results, monthly PM completion reports, a could-not-locate list, records of devices removed from service, calibration certificates for test equipment, and a qualifications file for each technician.
