New Medicare coding change confusing pharmacies across multiple states

A recent Medicare coding change is causing confusion and claim denials for pharmacies in several states. The report indicates that unclear guidance from CMS or its contractors on the implementation of new codes or modifiers is disrupting the pharmacy billing workflow. This type of administrative ambiguity often leads to cash flow interruptions and increased back-end rework. Pharmacy-based practices and those with integrated dispensaries should immediately audit recent Medicare Part B and D claim rejections related to code changes. Contact your Medicare Administrative Contractor (MAC) for clarification and document any new billing instructions to avoid future denials.
