Updated: Sep 7
A Predetermined Change Control Plan (PCCP) is FDA documentation that lets you pre-define specific AI/ML software changes—and the methods to develop, validate, implement, and monitor them—so those updates can be made without a new marketing submission, when executed exactly as an authorized PCCP. PCCPs include three components: Description of Modifications, Modification Protocol, and Impact Assessment. Available for 510(k), De Novo, and PMA pathways for AI-enabled device software functions.
This guide covers the final December 2024 FDA guidance requirements, implementation strategies, and practical examples for successful PCCP development.
What Is a Predetermined Change Control Plan (PCCP)?
A Predetermined Change Control Plan is a regulatory framework that allows manufacturers to implement pre-approved modifications to AI-enabled medical devices without submitting supplemental marketing applications for each change. This approach addresses the iterative nature of AI/ML development while maintaining safety and effectiveness standards.
Why PCCPs Are Essential for AI Medical Devices
Traditional Change Control Limitations: Conventional medical device change control requires new submissions (Special 510(k), PMA supplement) for significant software modifications. For AI devices that continuously learn and improve, this creates regulatory bottlenecks that can delay critical updates.
PCCP Strategic Advantages:
Continuous Innovation: Implement AI improvements without regulatory delays
Cost Reduction: Eliminate expensive supplemental submission cycles
Competitive Edge: Deploy algorithmic enhancements faster than competitors
Patient Benefit: Accelerate delivery of improved diagnostic accuracy and treatment outcomes
FDA Regulatory Authority
The FDA's PCCP authority stems from the Food and Drug Omnibus Reform Act (FDORA) of 2022, which added section 515C to the Federal Food, Drug, and Cosmetic Act. This provides express statutory authority for FDA to authorize predetermined change control plans as part of initial marketing submissions.
AI-DSF Definition and Scope
Updated FDA Terminology (2025)
The final FDA guidance transitioned from "Machine Learning-Enabled Device Software Functions (ML-DSF)" to "Artificial Intelligence-Enabled Device Software Functions (AI-DSF)" to reflect broader AI application scope.
FDA AI Definition: "A machine-based system that can, for a given set of human-defined objectives, make predictions, recommendations, or decisions influencing real or virtual environments."
AI-DSF Definition: "A device software function that implements an AI model" and includes various AI techniques beyond just machine learning algorithms.
PCCP Applicability

Three Essential PCCP Components
Component 1: Description of Modifications
This section specifies exactly what changes will occur to the AI-DSF and their expected impact on device performance.
Required Elements:
Specific Modification Types:
Algorithm parameter adjustments and threshold modifications
Training data updates and model retraining procedures
Performance metric improvements (sensitivity, specificity, accuracy)
User interface enhancements that affect AI functionality
Integration updates for interoperable system compatibility
Device Characteristic Changes:
Quantified performance improvements with statistical bounds
Changes to device outputs, alerts, or recommendations
Modifications to data input requirements or processing methods
Updates to risk mitigation measures or safety controls
Implementation Approach:
Automatic updates through software deployment systems
Manual updates requiring healthcare provider intervention
Hybrid approaches with user confirmation requirements
Rollback procedures for unsuccessful modifications
Example Description: "The AI-DSF will implement algorithm parameter adjustments to improve diagnostic accuracy for detecting diabetic retinopathy in retinal images. Modifications include sensitivity threshold adjustments (±5%), specificity optimization (target >95%), and integration of additional training data representing diverse patient populations. Updates will be deployed automatically with healthcare provider notification and 30-day performance monitoring period."
Component 2: Modification Protocol
This section details the systematic approach for developing, validating, and implementing the planned modifications.
Development Methodology:

Frequently Asked Questions
What types of AI device modifications require a PCCP versus traditional change control?
PCCP is appropriate for planned, iterative AI improvements within intended use boundaries. Traditional change control applies to unplanned changes, hardware modifications, or changes affecting device indications for use.
How does FDA review PCCP submissions differently from standard device submissions?
FDA evaluates PCCPs as part of the initial marketing submission, focusing on modification protocols, validation procedures, and impact assessments rather than reviewing each individual change.
Can we modify our PCCP after FDA approval of our initial submission?
PCCP modifications typically require supplemental submissions unless the changes are minor and within the original PCCP scope. Major PCCP changes may require new marketing submissions.
How do we handle modifications that exceed our approved PCCP scope?
Modifications outside PCCP boundaries require traditional change control procedures, potentially including Special 510(k), De Novo supplement, or PMA supplement submissions.
What happens if our PCCP modifications don't perform as expected?
PCCPs must include rollback procedures and failure response protocols. Performance monitoring requirements help identify issues early, and corrective actions should be documented and reported to FDA.
