Code reset Summary of 2026 ICD-10 changes and ICD-11 news
Ensure your practice is prepared to navigate annual updates
Ensure your practice is up to date with the latest changes to the ICD-10-CM coding and reporting guidelines, which take effect annually on Oct. 1. These codes are maintained by the Centers for Disease Control and Prevention’s (CDC) National Center for Health Statistics (NCHS) under the authorization of the World Health Organization (WHO) and were developed for use by the Centers for Medicare & Medicaid Services (CMS).
The AOA provides resources to help osteopathic physicians navigate updates to the ICD-10 code set, a comprehensive classification system for diagnoses, symptoms, abnormal findings, and external causes of injury or disease.

Update on ICD-11
In 2022, the World Health Organization (WHO) formally transitioned to the International Classification of Diseases, 11th Revision (ICD-11) code set, from ICD-10. The code set is now available for WHO member countries to adopt for recording and reporting health-related conditions. Use of standardized nomenclatures, such as ICD in diagnosis reporting is essential to healthcare operations, billing and payment and public health surveillance.
Since the first half of 2023, the AOA has been actively engaging with the National Committee on Vital Health Statistics (NCVHS) within the U.S. Department of Health and Human Services (HHS) to follow the committee’s evaluation of ICD-11 and development of recommendations regarding adoption and implementation of the code set in the U.S.
Overview of ICD-11 structure
ICD-11 as a code set is fundamentally different in structure from the ICD-10-CM code set. The code set uses a foundation, or system of base codes that can be rolled up into different categories, and then a system of extension codes to create granularity. Through this system of stem and extension combinations, a coding framework that accounts for more specific diagnoses and conditions that account for over 90% of the ICD-10-CM code set can be developed.1,2 For example, ICD-11 contains a single stem code for an arm fracture which can be paired with extension codes to describe where the fracture occurred.
A recent analysis of the adequacy of ICD-11 for morbidity coding was conducted by researchers at the National Library of Medicine. Researchers performed one horizontal sample of the most commonly used ICD-10 codes and one vertical sample across the digestive diseases section of the ICD-10-CM. Key findings from this analysis were that:
- Overall, ICD-11 provides much more descriptive detail than ICD-10
- Over 90% of current ICD-10-CM codes can be mapped to ICD-11 following mapping processes referred to as “post coordination” and “linearization”
- Gaps in the code set are dispersed and not specific to any condition areas
Key considerations for somatic dysfunction
The ICD-11 code set generally provides sufficient granularity to map ICD-10 to ICD-11. Further, it may allow coding for somatic dysfunction with greater detail than is currently possible. Similar to the arm fracture example noted above, this would be achieved by using the somatic dysfunction base code with extension codes for surface topography.
However, there are more than 10 surface topography extension codes (compared to the 10 body regions specified in current ICD-10 somatic dysfunction codes). Thus, when being implemented in the U.S., policymakers must define what combinations of stem and extension codes are appropriate. AOA must be closely engaged in the post-coordination process.
Adoption of the ICD-11 code set in the U.S. and timeline uncertainty
The process of adopting and implementing ICD-11 is highly dependent on U.S. engagement with WHO. The WHO must support any post-coordination efforts countries wish to implement and must also grant states permission if they wish to engage in clinical modification.3 Additionally, unlike ICD-10, the ICD-11 code set is designed to be updated regularly, and WHO has established a process for doing so where stakeholders can request new codes or modifications. Ultimately, the post-coordination process in the U.S. will require working with WHO to define the appropriate extensions.
Based on historical precedent, there are several critical steps that typically must be taken in order for ICD-11 to be adopted and implemented in the U.S.:
- The National Committee on Vital Health Statistics must make a recommendation to the HHS Secretary regarding the adoption of ICD-11 and the agency that should be responsible for the process, including liaising with WHO.
- A liaison to WHO must be appointed.
- A mapping of ICD-11 to ICD-10-CM across the code set must be completed.
- WHO must approve any modifications if the code set is not implemented in its entirety.
- HHS must issue a notice of proposed rulemaking and seek public comment on adoption.
This multi-year process has not yet been initiated. Additionally, recent actions by the Trump administration, including a restructuring of the Department of Health and Human Services, as well as threats to withdraw from the World Health Organization, have created uncertainty regarding the timeline and process for a potential transition. The AOA is monitoring developments closely and will keep members updated as information becomes available.

Next steps
The 2026 ICD-10-CM code changes are now active and must be used for all services delivered between Oct. 1, 2025, and Sept. 30, 2026. The next annual update will take effect on Oct. 1, 2026.
Recommended actions for provider practices
To ensure compliance and minimize disruptions, practices should take the following steps:
- Review code and guideline changes
Prioritize reviewing updates to the codes most frequently used in your practice, then expand to others that may affect your documentation or billing.
- Update documentation practices
Ensure your clinical documentation supports the specificity required by new codes. Revise templates and workflows as needed.
- Communicate with physicians and staff
Alert providers and train all staff involved in coding, billing and documentation. Review changes together and identify any necessary process updates.
- Verify software compatibility
Confirm with your EHR and billing software vendors that the 2026 ICD-10-CM updates have been implemented. Test functionality and follow up promptly if updates are missing.
- Check health plan guidance
Review payer-specific instructions or coverage changes related to the new codes to avoid claim denials or delays.
- Stay informed year-round
ICD-10-CM updates occur annually, with potential mid-year additions. Monitor official sources like CMS and the AOA for ongoing changes.
Frequently asked questions
Who must use ICD-10 codes?
All HIPAA-covered entities (health plans, providers, clearinghouses) are required to use ICD-10-CM for diagnosis coding and ICD-10-PCS for inpatient procedure coding in all electronic health transactions. Plans may also require ICD-10 on paper claims for consistency.
Do I need to learn the entire ICD 10 code set?
Practices should focus on the codes most relevant to their specialty, ensuring documentation supports required specificity. Full mastery of all codes isn’t necessary but knowing your commonly used subsets is critical.
What documentation specificity is needed?
Documentation must support the specificity required by ICD-10, detailing laterality, severity and encounter type (e.g., initial vs. subsequent). Use the ICD-10-CM Official Guidelines and ensure all descriptors are clearly documented.
