Roadmap to CMS eCQM Compliance
- Your EMR cannot produce these numbers. The measure runs on image-level data, not EMR fields, and requires calculations standard EMR systems do not perform. Compliance teams who assume this is a reporting configuration will discover the gap late.
- Three values are required for every CT exam: CT Category, Global Noise Level, and Size-Adjusted Radiation Dose. None of them exist at the time of the exam. All three have to be calculated from exported DICOM data by specialized software and then delivered back to the EMR and patient record.
- This is a cross-departmental measure, not a compliance department measure. Radiology, Physics, IT, and Compliance all own a piece of it, and none of them can finish it alone. The first real task is a kickoff meeting with named owners, not a software evaluation.
- The mandatory date is gone, but the work is not. The CY 2026 OPPS Final Rule extended voluntary outpatient reporting indefinitely with no replacement deadline, while CMS restated its commitment to the measure. Voluntary reporting has been live across all programs since CY 2025, which makes this the window to build and test rather than wait.
- Your timeline is set by legal and IT, not by radiology. Security review, vendor access approvals, and procurement lead times routinely take longer than the technical implementation. Organizations that start with the software question and reach the security question last are the ones that miss their target date.

Roadmap to CMS eCQM Compliance
Who this guide is for
For hospital CMS compliance teams
This roadmap is designed for hospital compliance officers, quality directors, and CMS reporting leads who are responsible for electronic Clinical Quality Measures (eCQMs) but may be unfamiliar with this imaging-based requirement: “Excessive Radiation Dose or Inadequate Image Quality for Diagnostic CT in Adults.” If your team has not yet engaged Radiology, or is not sure where to begin, this guide walks you through each critical step toward compliance readiness.
Why this measure is different
- It is based on image-level data, not EMR fields
- It requires complex calculations unavailable in standard EMR systems
- It evaluates both radiation dose and diagnostic image quality
- It demands new workflows across Radiology, Physics, IT, and Compliance
Updated: Current regulatory status
The CY 2026 OPPS Final Rule (November 2025) extended voluntary outpatient reporting indefinitely. The original CY 2027 mandatory date has been removed and no new mandatory date has been set.
CMS remains committed to the measure as a patient safety issue for cancer prevention and will continue to monitor implementation progress, data collection burden, and response rates. IQR and MIPS remain self-selectable. Voluntary reporting is live across all programs as of CY 2025.
Step OneIdentify internal owners
Start by mapping stakeholders. These roles will streamline your compliance effort:
- Director of Radiology or Imaging Services
- PACS Administrator or Radiology IT Lead
- Diagnostic Medical Physicist
- CT Modality Manager or Technologist Supervisor
- Administrator for your imaging analytics or radiology operations platform
- Compliance and Quality Reporting Team
Hold a cross-functional kickoff meeting to:
- Introduce the CMS measure
- Review workflow, data, and software requirements
- Assign ownership and next steps across departments
Ask
- Do we know who currently handles CMS reporting?
- Have they been briefed on this specific measure?
- Has Radiology been brought into these conversations?
- Has a vendor already engaged with someone at your organization?
Step TwoUnderstand what is required
Each CT exam must include three calculated values:
-
CT CategoryCMS-defined protocol grouping
-
Global Noise LevelQuantified image quality value
-
Size-Adjusted Radiation DosePatient-normalized dose metric
These values are not available at the time of the CT exam. They must be calculated from exported DICOM image data using specialized software, which is then sent to your EMR and patient record.
Ask
- Have we seen a detailed breakdown of the required data fields?
- Do we know what we currently collect, and what is missing?
Step ThreeDetermine your technical capability
To comply with this measure, your organization must be able to calculate and extract specific values from CT image data, not just retrieve fields from the EMR. This requires a combination of:
- Software that can perform the CMS-compliant calculations from image-level data
- PACS and scanner integration to access DICOM metadata and image-level attributes
- Translation functionality to convert this data into a CMS-ready submission format
Inventory existing tools
Confirm which imaging analytics or radiology operations platforms are currently in use. Document which hospitals or imaging sites are covered, and whether they include CT.
Verify software capabilities
Contact your vendors or review documentation to determine whether your existing platform can calculate the three reportable CMS metrics and pass them to the next step.
Review data fidelity
Determine whether your current platform can:
- Support export in CSV or FHIR format
- Transmit data to CMS directly or integrate with your EMR for handoff
Loop in IT security and informatics teams
Depending on whether you are using a cloud or on-premises platform, your IT and compliance teams will need to evaluate:
- Network security and data storage requirements
- Vendor access policies and integration approvals
- Lead times for internal procurement or legal review if needed
Ask
- What software are we using today for image analytics or dose data?
- Has the vendor confirmed they support the CMS eCQM calculations?
- Are we capturing the necessary scanner-level data?
- Do we have translation or export capabilities aligned with CMS formats?
- Has IT been consulted about the deployment?
Step FourAlign budget and resources
Be proactive about financial planning and resource allocation:
- Licensing or upgrading imaging analytics software
- PACS or IT integration work
- Radiology time for outlier review and protocol optimization
- Compliance or vendor support for data validation and submission
Ask
- Has a CMS compliance budget been created for 2026 through 2028?
- Have Finance and IT been briefed on potential costs?
- What is the lead time for implementation and internal security approvals?
Watch forAvoid common mistakes
- Do not assume your EMR captures the required data
- Do not wait to engage Radiology. They are critical to success
- Do not delay. Legal and IT review timelines may push your implementation past your target date
The finish lineWhat success looks like
You have:
- Mapped ownership across Radiology, Compliance, IT, and Finance
- Confirmed software capabilities for CMS-required values
- Chosen a submission method and validated the format
- Built a repeatable workflow for review and reporting
- Tested outputs ahead of any mandatory deadline
Need help getting started?
Your Radiology team, compliance team, or physicist may already be working with a vendor. Start there.
Ask
- What software are we using today?
- Can it support CMS reporting?
- Who are the main vendor contacts who can help support this CMS measure?
Questions from This Article
- With no mandatory deadline, why start now?
Because the calendar is the only thing that got easier. The measure still requires new data flows, new calculations, and coordination across four departments, and none of that gets faster under deadline pressure. CMS said explicitly that the extension is meant to give hospitals time to gain implementation experience. Building during a voluntary period means you can test your outputs, find your data gaps, and fix them before anything counts.
- We already have imaging analytics software. Does that mean we are covered?
Not automatically. Having a platform in place is different from having one that calculates all three CMS-required values and can export them in a submission-ready format. Ask your vendor to confirm three things in writing: that they calculate CT Category, Global Noise Level, and Size-Adjusted Radiation Dose to the measure specification, that they support CSV or FHIR export, and that they can either transmit to CMS or hand off cleanly to your EMR. Also confirm which of your sites and modalities are actually covered, since coverage often varies across a system.
- Who should own this internally?
No single department can. In practice the most successful structure pairs a compliance or quality lead who owns the submission with a radiology lead who owns the data, supported by a PACS administrator, a diagnostic medical physicist, and an IT security contact. If your compliance team has not yet talked to Radiology, that conversation is the actual first step, ahead of any budget or vendor discussion.
