March 1, 2021 Policy Updates / Reimbursement Policies
Beginning with dates of service on or after February 1, 2021 Anthem has implemented revised claims editing logic tied to Excludes 1 notes from ICD-10-CM 2020 coding guidelines. To help ensure the accurate processing of claims, use ICD-10-CM Coding Guidelines when selecting the most appropriate diagnosis for member encounters. Please remember to code to the highest level of specificity. For example, if there is an indication at the Category level that a code can be billed with another range of codes, it is imperative to look for Excludes 1 notes that may prohibit billing a specific code combination.
