Appropriate Use of Modifier 59

June 14, 2011

On March 21, 2011, BCBSIL implemented ClaimsXtenTM, a code auditing tool developed by McKesson Information Solutions, Inc. Modifier-to-procedure validation edits were added into our auditing logic with the implementation of ClaimsXten. BCBSIL will now request a corrected claim when it is determined, based on correct coding guidelines, that an inappropriate modifier was appended to a CPT® or HCPCS code.

Modifier 59 is used to report that a service is a distinct procedural service. Based on the definition of modifier 59, it would be inappropriate to append modifier 59 to non-procedural services. Non-procedural services would include, but are not limited to, HCPCS codes for surgical supplies, including surgical trays (HCPCS code A4550). 

Clear Claim ConnectionTM (C3) will continue to be the provider resource that allows disclosure of claim auditing rules and clinical rationale to the BCBSIL independently contracted provider network. C3 is a free online tool available to providers who are registered with Availity® and/or RealMed®.
