AUC Program 2026: Healthcare Compliance Checklist - Are You Ready for CMS Requirements?

What's the Current Status of AUC Implementation and Should We Still Prepare?

The Appropriate Use Criteria compliance landscape underwent significant changes in 2024. The Centers for Medicare & Medicaid Services (CMS) officially paused the AUC program implementation on January 1, 2024, rescinding regulations at 42 CFR 414.94. However, this pause doesn't eliminate the underlying PAMA mandate—it's a strategic reevaluation period.

Healthcare professionals should absolutely continue preparing for AUC program 2026 implementation. The pause allows organizations to refine their healthcare compliance 2026 strategies without immediate penalty pressure. CMS explicitly encourages voluntary use of clinical decision support mechanisms, recognizing their value in improving patient care quality.

TL;DR: While CMS paused AUC implementation in 2024, healthcare organizations should maintain voluntary compliance readiness. The program will likely resume with enhanced requirements, making early preparation essential for avoiding penalties and ensuring quality patient care. Key focus areas include CDSM selection, staff training, and EHR integration.

Key Action Items:

• Maintain existing CDSM implementations
• Continue staff training programs
• Monitor CMS guidance updates
• Document compliance efforts for future reporting

Industry experts anticipate a more robust framework when the program resumes, potentially incorporating lessons learned during the testing period. Organizations maintaining compliance readiness will have competitive advantages in care quality metrics and operational efficiency.

How Do I Choose the Right Clinical Decision Support Mechanism (CDSM)?

Selecting an appropriate clinical decision support mechanism requires careful evaluation of your organization's specific needs. CMS previously qualified multiple CDSMs, though the qualification process is currently paused.

‍

Leading CDSM providers include American College of Radiology (ACR) Select, National Decision Support Company (NDSC), and AIM Specialty Health. Free options exist but may require more manual integration efforts.

The CMS AUC requirements historically emphasized evidence-based criteria from professional medical societies. When evaluating CDSMs, prioritize those incorporating guidelines from recognized organizations like the American College of Radiology, American Academy of Orthopaedic Surgeons, and other specialty societies.

What Are the Financial Penalties for Non-Compliance When AUC Resumes?

Understanding potential CMS appropriate use criteria penalties helps organizations prioritize compliance investments. While specific penalty structures for the resumed program aren't finalized, historical plans provide guidance.

Anticipated Penalty Framework:

• Phase 1: Educational period with claims processing delays
• Phase 2: Prior authorization requirements for outlier providers
• Phase 3: Claims denials for non-compliant orders
• Phase 4: Medicare reimbursement restrictions

The advanced diagnostic imaging compliance program originally targeted high-cost procedures including MRI, CT, PET, and nuclear medicine studies. Non-compliance could result in:

• Immediate claims denials
• Administrative burden from prior authorization requirements
• Potential audit flags
• Reputational impact with payers

Financial impact varies by organization size and imaging volume. Large health systems could face millions in denied claims, while smaller practices might experience cash flow disruptions from delayed reimbursements.

Which Imaging Services Require AUC Consultation?

Healthcare compliance trends 2026 indicate continued focus on advanced diagnostic imaging services. The AUC program specifically targets high-cost, high-volume procedures with significant utilization variability.

Covered Services Include:

• Magnetic Resonance Imaging (MRI)
• Computed Tomography (CT)
• Nuclear Medicine studies
• Positron Emission Tomography (PET)
• Myocardial perfusion imaging

Applicable Settings:

• Physician offices
• Hospital outpatient departments
• Ambulatory surgical centers
• Independent diagnostic testing facilities

Payment Systems Covered:

• Medicare Physician Fee Schedule
• Hospital Outpatient Prospective Payment System
• Ambulatory Surgical Center Payment System

Emergency services, inpatient procedures, and certain hardship exceptions remain exempt. However, organizations should document exemption rationales carefully for potential audit review.

The program doesn't apply to Medicare Advantage beneficiaries, though private payers increasingly adopt similar requirements.

How Do I Integrate AUC Requirements with My Existing EHR System?

Successful AUC clinical decision support tools integration requires strategic EHR workflow planning. Most major EHR vendors offer native CDSM integrations or certified third-party solutions.

‍

Implementation Best Practices:

1. Conduct workflow mapping before integration
2. Establish user training protocols
3. Create audit trails for compliance documentation
4. Test integration with sample cases
5. Monitor system performance metrics

Popular EHR platforms like Epic, Cerner, and Allscripts offer varying levels of AUC support. Evaluate your vendor's roadmap for enhanced appropriate use criteria compliance features.

What Modifier Codes and G-Codes Do I Need for AUC Reporting?

CMS AUC requirements historically included specific coding requirements for claims reporting. While currently paused, understanding these codes helps prepare for program resumption.

Key Modifier Codes:

• QQ: AUC consultation occurred (general reporting)
• MA: Appropriate via CDSM consultation
• MB: Inappropriate via CDSM consultation
• MC: Unable to determine appropriateness
• MD: Clinical situation not addressed by AUC

G-Codes for CDSM Identification:

• G1000-G1024: Specific qualified CDSM identifiers
• G1011: Qualified CDSM without assigned G-code

Proper coding ensures compliance tracking and facilitates outcome analysis. Claims processing systems should accommodate these codes even during the pause period to maintain readiness.

Training billing staff on healthcare compliance 2026 coding requirements prevents future implementation delays and ensures accurate financial reporting.

How Can I Train My Staff on AUC Compliance Requirements?

Effective staff training programs address both clinical and administrative aspects of AUC program 2026 requirements. Multi-disciplinary training ensures consistent implementation across all touchpoints.

Training Program Components:

Clinical Staff Training:
