Are you coding the UD modifier correctly?

By: Marney Wilson

The UD modifier is used to identify medical claims for outpatient physician-administered drugs and signifies to CMS that they need to pay the manufacturer rebate and the amount to pay the provider. Keep in mind that using the UD modifier is not a recommendation, it is a federal requirement! Potential ramifications of not using the modifier include repaying the difference between the billed amount and the acquisition price, as well as the manufacturer's rebate.

Here are a few tips to ensure your coding is accurate:

  • When Medicaid is primary payer: Use “UD” modifier for each 340B drug with an acquisition cost. Remember to always verify appropriate modifiers with your state Medicaid program.

  • When Medicaid is secondary payer: The claim must be appended with the “UD” modifier for each 340B drug if the primary payer did not require the modifier.

  • When preparing for program audits: Maintain audible records documenting compliance with all 340B Program requirements.
