Medical Device Inventory

The medical device inventory requirement means you must maintain a current, complete list of every networked medical device and record, at minimum, the manufacturer, model, firmware version, and network location. To operationalize it quickly, define “in scope,” assign device ownership, choose a system of record, and implement repeatable discovery and reconciliation so the inventory stays accurate. ¹

Key takeaways:

• Scope is “networked medical devices,” not just EHR-connected or “owned by Biomed.”
• Minimum fields are non-negotiable: manufacturer, model, firmware version, network location; add OS and FDA classification for a workable security view.
• Auditors will test completeness and freshness, not whether you have a spreadsheet.

For a CCO or GRC lead, “medical device inventory” is an operational control that turns medical device security from ad hoc firefighting into something you can govern: patching decisions, vulnerability triage, segmentation, and third-party support all depend on knowing what devices exist and where they are. HICP Practice 9.1 sets a clear expectation: maintain a comprehensive inventory of all networked medical devices, including key technical identifiers and their network location. ¹

The compliance risk is straightforward: if you cannot enumerate networked devices, you cannot reliably demonstrate you manage their cybersecurity risk. In practice, gaps usually show up during incident response (“we didn’t know that device was on that VLAN”), vulnerability management (“we can’t map a CVE to devices”), or during a security assessment when a sampling test finds devices not recorded or recorded with stale firmware and location data.

This page gives requirement-level implementation guidance: who must comply, what “comprehensive” needs to mean operationally, step-by-step execution, evidence to retain, audit questions, common pitfalls, and an execution plan you can run with your IT, Security, and Clinical Engineering teams.

Regulatory text

Requirement (HICP Practice 9.1): “Maintain a comprehensive inventory of all networked medical devices including manufacturer, model, firmware version, and network location.” ¹

Operator interpretation: You need a system of record that enumerates every medical device that communicates on your network, with enough device identity and technical detail to support security operations. The practical minimum is:

• Manufacturer
• Model
• Firmware version
• Network location (at least IP address and/or VLAN/segment and facility/department mapping)

HICP’s plain-language summary expands the dataset you should capture to make the inventory security-usable:

• Operating system
• FDA classification ¹

Treat this as a living control. A one-time list is not an inventory. Your program must include ongoing discovery, reconciliation, and governance so the data stays accurate as devices move, get replaced, or receive updates.

Plain-English requirement interpretation (what “good” looks like)

A compliant medical device inventory answers four questions at any moment:

1. What is on my network that is a medical device?
2. What exactly is it (make/model/firmware/OS)?
3. Where is it (network segment and physical/operational location)?
4. Who is responsible for it (clinical owner and technical custodian) so issues get fixed?

“Comprehensive” does not mean “perfect metadata for everything on day one.” It means your discovery and reconciliation process can reasonably find all in-scope networked medical devices, and you can show how you detect and correct gaps.

Who it applies to

Entity types:

• Healthcare organizations (providers, hospitals, clinics, health systems)
• Health IT vendors (especially those hosting, managing, or monitoring device-connected environments) ¹

Operational contexts where this becomes mandatory in practice:

• Any environment where medical devices connect via wired, Wi‑Fi, or other IP-based networking
• Environments with shared responsibility across Clinical Engineering/Biomed, IT Networking, Security, and third parties (manufacturers and managed service providers)
• Mergers, acquisitions, and facility expansions where device standardization is inconsistent

What you actually need to do (step-by-step)

1) Set your scope and definitions (write it down)

Create a short scoping statement that includes:

• In scope: “networked medical devices” (devices that communicate on the network and meet your organization’s definition of medical device)
• Out of scope (explicit): truly non-networked devices; test benches; disconnected training units; or anything else you can justify consistently
• System boundary: all facilities, clinics, and remote sites that connect to your enterprise network

Deliverable: a one-page “Medical Device Inventory Scope & Ownership” standard that Security, IT, and Clinical Engineering sign off.

2) Choose your system of record and data model

Pick one authoritative repository. Common options are a CMDB, an asset management platform, or a dedicated medical device security tool. Whatever you pick must support:

• Unique device identifier (your internal asset ID)
• Required fields: manufacturer, model, firmware version, network location ¹
• Recommended fields: operating system, FDA classification ¹
• Change history (who changed what and when)
• Export/reporting for audit and security workflows

If your CMDB is immature, you can start with a controlled dataset (even a structured spreadsheet) as a temporary system of record, but define the migration path and controls around change approvals.

3) Establish authoritative sources for device truth

You will not get accurate medical device data from one place. Decide which system is “authoritative” for each field:

Field	Preferred authoritative source	Backup source
Manufacturer / Model	Clinical Engineering records; procurement data	Device labeling; manufacturer portal
Firmware version	Device management console; passive network identification	Manual verification during rounds
OS	Device security tool fingerprinting; manufacturer documentation	Third-party service reports
Network location	Network management (DHCP, IPAM), switch port maps	Manual mapping by site IT
FDA classification	Manufacturer documentation	Internal clinical engineering catalog

Make these decisions explicit so teams don’t argue during reconciliation.

4) Implement device discovery that finds the “unknown unknowns”

Use at least two complementary discovery methods:

• Network-based discovery: passive monitoring and/or active scanning aligned with clinical safety constraints
• Operational discovery: procurement/intake, receiving, and deployment workflows that register devices before they go live

Operational rule: “No device goes on the network without an inventory record.” Enforce it via network access controls where feasible, or via a documented approval gate owned by IT Networking and Clinical Engineering.

5) Reconcile and remediate gaps (this is where compliance is won)

Run a reconciliation cycle:

• Compare discovered devices vs. inventory
• Triage exceptions:
  • Not in inventory
  • In inventory but missing required fields
  • In inventory but stale firmware or wrong location
  • Duplicates (same device recorded multiple times)
• Assign remediation owners and due dates:
  • Clinical Engineering for device identity and lifecycle details
  • IT Networking for network location accuracy
  • Security for risk tagging and segmentation requirements

Keep evidence of the reconciliation results and closure actions.

6) Operationalize lifecycle events

Inventory breaks at lifecycle transitions. Add controls at these points:

• Procurement: require manufacturer, model, FDA classification, and support contacts before purchase approval
• Receiving & deployment: assign asset ID, capture location, confirm network segment
• Change management: firmware updates and major configuration changes must update inventory
• Moves/adds/changes: device relocations must update location fields
• Decommission: remove from network first, then retire record with date and disposition

7) Tie the inventory to security workflows (or it becomes shelfware)

Minimum integrations or handoffs:

• Vulnerability alerts: map advisories/CVEs to manufacturer/model/firmware
• Network segmentation: ensure each device’s VLAN/segment is known and appropriate
• Incident response: identify affected devices by location and model quickly
• Third-party access: ensure remote service connections are tracked to specific devices

If you use Daydream for third-party risk management and due diligence, connect device inventory to third-party service relationships. That linkage helps you answer: “Which third parties can access which medical devices, in which facilities, under what support terms,” without scrambling across spreadsheets.

Required evidence and artifacts to retain

Auditors and assessors usually ask for proof that the inventory exists, is complete, and is maintained. Retain:

• Inventory export showing required fields (manufacturer, model, firmware, network location) and recommended fields (OS, FDA classification) ¹
• Inventory policy/standard defining scope, ownership, and update triggers
• Data dictionary for fields and acceptable values
• Discovery methodology documentation (tools used, frequency, safety constraints, exclusions)
• Reconciliation reports (identified gaps, tickets created, closure evidence)
• Change records showing inventory updates after firmware changes and device moves
• Decommission logs showing devices removed from network and retired in inventory
• Exception register for devices that cannot be scanned or have incomplete metadata, with compensating controls

Common exam/audit questions and hangups

Expect these:

• “Show me the inventory and prove it covers all networked medical devices.”
  Hangup: teams show a Biomed list that excludes radiology, lab, or leased devices.
• “How do you keep firmware versions current?”
  Hangup: firmware is captured once during install and never updated after service events.
• “How do you know a device hasn’t been moved to a different network segment?”
  Hangup: physical location and network location are conflated; neither is reliable.
• “Who owns accuracy for each field?”
  Hangup: Security assumes Biomed owns it; Biomed assumes IT owns it.
• “How do you identify devices managed by third parties?”
  Hangup: remote support relationships exist but are not tied to device records.

Frequent implementation mistakes (and how to avoid them)

1. Treating inventory as a spreadsheet project, not a control.
   Fix: define lifecycle triggers and reconciliation, then automate collection where safe.

2. Only inventorying “medical devices we purchased,” not “medical devices on the network.”
   Fix: start from network discovery and reconcile back to procurement, not the reverse.

3. Missing firmware versions because “the manufacturer manages it.”
   Fix: require firmware confirmation after service events; keep a field for “last verified firmware date” if exact version is hard to collect consistently.

4. No unique identifier strategy.
   Fix: assign an internal asset ID and prevent duplicates by matching on multiple identifiers (MAC, hostname, serial where available).

5. Ignoring leased, trial, or research devices.
   Fix: include them if networked; handle exceptions through a documented, time-bound process.

Enforcement context and risk implications

No public enforcement cases are provided in the source catalog for this requirement. From a risk standpoint, inventory gaps typically translate into:

• Inability to scope incidents involving device networks
• Unpatchable or untracked devices persisting on high-trust segments
• Weak third-party access governance because support connections are not mapped to device assets

Treat inventory as foundational. If an assessor sees missing devices or stale firmware data, they often infer broader control weaknesses in change management and network governance.

Practical execution plan (30/60/90-day)

First 30 days (stabilize scope and ownership)

• Publish scope statement for “networked medical devices” and define required fields per HICP Practice 9.1. ¹
• Assign RACI across Clinical Engineering, IT Networking, and Security.
• Select the system of record and approve the data dictionary.
• Run an initial discovery in a limited segment or pilot facility if scanning constraints exist.

By 60 days (build the repeatable process)

• Expand discovery coverage and reconcile findings to the inventory.
• Stand up an exception workflow for devices that cannot be interrogated for firmware/OS.
• Implement intake controls: procurement and deployment cannot proceed without an inventory record.
• Produce your first “inventory completeness” report and review it with operational owners.

By 90 days (make it auditable and security-usable)

• Operationalize change triggers: firmware updates and device moves create inventory update tasks.
• Link inventory to vulnerability intake and network segmentation decisions.
• Run a second reconciliation cycle and show closure evidence on previously found gaps.
• Prepare an audit-ready evidence packet: policy, inventory export, reconciliation reports, exception register.

Frequently Asked Questions

Do we have to inventory non-networked medical devices?

HICP Practice 9.1 is specific to “networked medical devices.” Keep your scope statement explicit so assessors see a consistent rationale for what is excluded. ¹

What counts as “network location” for audit purposes?

Capture at least an IP address and the network segment (VLAN/subnet) plus a facility/department mapping. If IPs change often, treat VLAN/subnet and switch-port mapping as the more durable location evidence.

We can’t always get firmware versions. Are we noncompliant?

Firmware version is part of the stated inventory requirement, so you need a defined method to obtain it or a controlled exception process. Track which devices are missing firmware data, why, and what compensating controls you apply, then drive closure with owners. ¹

Who should own the medical device inventory: Security, IT, or Clinical Engineering?

Make ownership split by field: Clinical Engineering typically owns device identity and lifecycle, IT Networking owns network location accuracy, and Security owns risk tagging and oversight. Put that in a RACI and enforce it through reconciliation workflows.

How do we handle devices managed or serviced by a third party?

Record the third party relationship in the device record: support contact, remote access method, and service windows. In Daydream, map those third-party relationships to the device inventory so third-party risk reviews and access governance stay tied to real assets.

Can we start with a spreadsheet?

Yes, if it is structured, access-controlled, and backed by a defined reconciliation and change process. Treat it as a temporary system of record and plan the migration once you can support discovery feeds and change history.
