Changes coming to application of Modifier 59 in 2019 

January 11, 2019    

Effective April 12, 2019, Independence will deny single line claims that are billed with Modifier 59. The reason for this change is to align our Modifier 59 policies with our position prohibiting split-billing of claims.


Providers have been permitted to submit claims with modifiers XE, XS, XP, and XU since January 1, 2015. These modifiers were developed to provide greater reporting specificity in situations where Modifier 59 was previously reported. The Independence policies regarding modifiers XE, XS, XP, XU, and 59 specifically states that Modifier 59 should only be added to a claim when it is the most accurate modifier that is available to describe the circumstances of the procedure or service, and modifiers XE, XS, XP, or XU do not meet the criteria.

Modifier 59 is used for a “Distinct Procedural Service.” In some circumstances, the physician may need to indicate that a procedure or service was distinct or independent from other services performed on the same day.

When a single service is billed with Modifier 59 (single-line claim), it is an indication that either:

  • one of the more specific modifiers such as XE or XP would meet the criteria, and therefore Modifier 59 should not have been used; or
  • the claim is being split-billed from another service rendered on the same day by the same provider.

Split-billing is prohibited under the Hospitalization and Outpatient Services section of the Provider Manual for Participating Professional Providers.

To help ensure accuracy of claim submission and compliance with Independence’s prohibition against split-billing, we will no longer allow a Modifier 59 to be billed on a single line claim effective April 12, 2019. If a provider submits a single line claim with Modifier 59 on or after April 12, 2019, then it will be denied via a provider explanation of benefits.
