As we close out 2025, the healthcare industry is buzzing about the eventual shift to ICD-11. While there's no official US implementation date yet CMS and NCHS are still in research and planning phases industry experts project a possible transition window between 2026 and 2028. If you're a practice owner, provider, billing manager, or administrator, starting preparations now can prevent revenue disruptions, reduce denial risks, and position your practice for smoother compliance when the mandate arrives.
This guide breaks down what preparing for ICD-11 really involves, key differences from ICD-10-CM, and actionable steps to get ahead.
Key Takeaways for Busy Providers
No official US transition date; projections point to 2026-2028, with ongoing NCHS/CMS evaluations.
ICD-11 offers more granular codes (over 55,000 vs. ICD-10's ~70,000 but with better structure), post-coordination for detail, and digital-first design.
Early preparation focuses on training, EHR updates, dual coding pilots, and documentation improvements.
Practices that prepare proactively see fewer disruptions; delays in past transitions cost millions in denials.
Hybrid RCM partners like MedCloudMD are already building ICD-11 readiness into workflows for seamless future shifts.
What Is Preparing for ICD-11?
Preparing for ICD-11 means getting your practice ready for the World Health Organization's latest diagnostic classification system, which became effective globally in 2022. In the US, we'll likely use a clinical modification (ICD-11-CM) tailored for morbidity and billing, similar to how ICD-10-CM evolved.
Key features setting ICD-11 apart:
Post-coordination (clustering): Combine stem codes with extension codes for precise detail without exploding code counts.
Digital-native structure: Built for EHR integration, APIs, and natural language processing.
Enhanced specificity: New chapters for traditional medicine, functioning assessment, and better mental health groupings.
Ongoing updates: Annual refinements instead of massive overhauls.
Over 60 countries already use ICD-11 for reporting; the US is methodically evaluating it to ensure it fits our complex reimbursement needs.
Why Preparing for ICD-11 Matters Now
Even without a firm date, delays in preparation can be costly. The ICD-10 transition in 2015 saw widespread denials, productivity drops, and revenue lags for unprepared practices.
Today:
Payers and auditors increasingly scrutinize specificity; ICD-11's granularity will raise the bar.
EHR vendors and billing systems need time for mapping and testing.
Global data comparability is pushing momentum US isolation risks falling behind in research and quality reporting.
Staffing challenges: Coders trained only in ICD-10 may struggle with clustering and new concepts.
Practices starting now report stronger documentation habits and fewer current denials as a bonus.
Common Mistakes & Denial Risks During Transition
Past transitions highlight pitfalls that amplify denials:
Assuming "it's years away"leading to rushed, error-prone implementation.
Poor mapping from ICD-10: Only about 25% of codes directly equate; improper crosswalks cause upcoding/downcoding flags.
Inadequate training: Misunderstanding extension codes results in incomplete claims.
Documentation gaps: ICD-11 demands more clinical detail for clustering.
EHR delays: Unupdated systems reject new formats.
Real impact: During ICD-10, denial rates spiked 20-30% initially for many groups due to specificity issues.
Documentation & Compliance Tips Before Full ICD-11 Transition
Start building habits that align with ICD-11's clinical focus:
Enhance note detail: Include etiology, severity, anatomy, and temporality—key for post-coordination.
Pilot dual coding: Select high-volume diagnoses and practice mapping to ICD-11 equivalents.
Audit current claims: Identify areas where ICD-10 lacks granularity (e.g., mental health, rare diseases).
Engage vendors early: Confirm EHR/billing software roadmaps for ICD-11 support.
Train incrementally: Use WHO's free browser and tools for familiarity.
Real-World Examples of Early Preparation
Example 1: Multi-Specialty Group A cardiology and endocrinology practice began dual coding chronic conditions in 2025. They uncovered documentation gaps, improved notes, and reduced current denials by 15% positioning them strongly for ICD-11.
Example 2: Behavioral Health Clinic With ICD-11's expanded mental health categories, a therapy group trained on new groupings. This led to better risk adjustment capture today and confidence for the switch.
Example 3: Rural Primary Care Limited resources prompted partnership with an RCM expert for ICD-11 planning. Result: Customized training and system checks without internal strain.
These cases show preparation pays off even before the mandate.

FAQs About Preparing for ICD-11
When will the US fully transition to ICD-11? No official date yet; industry projections suggest 2026-2028, pending CMS rulemaking and potential clinical modification development.
Will ICD-11 replace ICD-10-PCS for procedures? No ICD-10-PCS remains separate; focus is on diagnostic (morbidity) codes.
How different is coding in ICD-11? More flexible with clustering; fewer standalone codes but greater detail through extensions.
Do I need to start training now? Yes, familiarity reduces future disruption; WHO tools are free.
Will my EHR support ICD-11? Most vendors are planning updates; confirm your roadmap early.
What are the biggest denial risks? Incomplete clustering and poor mapping during crossover periods.
