Accuracy Matters – Top CPT Modifiers of Concern Medicare

Accuracy matters! I recently saw where Novitas Medicare Intermediary receives nearly 1.7 million requests from Part B providers each year to correct minor errors or omissions of claim-specific information, which costs time and money for providers and the Medicare Program. Did you know the most requested claim correction is adding, changing, or deleting a modifier?

Modifier Definition

A modifier provides the means to indicate that a service or procedure that was performed has been altered by some specific circumstance, but not changed in its definition or code. Modifiers can be two digit numbers or two character alpha-numeric indicators. The purpose of using a modifier is to enable health care professionals to effectively respond to payment policy requirements.

Modifiers: A Three Step Process

1. Ensure the most current CPT and HCPCS coding manuals are used
2. Review modifier definitions in the CPT and HCPCS manuals to select the appropriate modifier
3. Determine if there is documentation to support the services reported
