Reminder: Important billing information for modifiers 25 and 59

May 1, 2015

This is a reminder that as of January 1, 2015, the Centers for Medicare & Medicaid Services (CMS) National Correct Coding Initiative (NCCI) edits are applicable to claims submitted on the CMS-1500 claim form or through the 837P transaction. Please refer to our Commercial and Medicare Advantage claim payment policies on NCCI edits which are available on our Medical Policy Portal. Select Accept and Go to Medical Policy Online, and then select the Commercial or Medicare Advantage tab from the top of the page, depending on the version of the policy you?d like to view:

  • Commercial: #00.01.56a: National Correct Coding Initiative (NCCI) Code Pair Edits;
  • Medicare Advantage: #MA00.041: National Correct Coding Initiative (NCCI) Code Pair Edits.

The CMS NCCI tables (Column 1/Column 2) are composed of code pair edits. These code pair edits identify services that are a component of a more comprehensive code or two codes that should not be reported together. Procedure code pairs designated by CMS with an NCCI modifier indicator of 0 (zero) are not eligible to be reimbursed separately when reported on the same date of service for the same member when performed by the same provider. The NCCI edit identified in the CMS NCCI file for these procedure code pairs will be applied by AmeriHealth regardless of the presence of a modifier.

Modifiers 25 and 59

Procedure code pairs designated by CMS with an NCCI modifier indicator of 1, when clinically appropriate, are eligible to be reported with an appropriate modifier for separate reimbursement. The most frequently used modifiers are 25 and 59.

  • Modifier 25: Modifier 25 is required when a significant, separately identifiable Evaluation and Management (E&M) service is performed by the same physician on the same day of a procedure or other service. For example, if an E&M service was also performed on the same day as an administration of an immunization, the E&M service should be billed with the modifier 25.
  • Modifier 59: Modifier 59 is required to indicate that a procedure or service is separate, distinct, or independent from other non-evaluation and management E&M services performed on the same day by the same individual.
