Call to Action

Although these code additions do not indicate a change to Medicare policy for these NCDs, it is essential to begin using the more specific codes when documentation supports their use. If documentation doesn’t support the added specificity, consider educating providers on the new ICD-10-CM documentation requirements for capturing these new codes for FY 2023
