Bundled Services/Supplies
Rebundling/Bundling: Reimbursement denial for any additional billed services that are components of or inclusive to, or mutually exclusive of a more comprehensive procedure performed in the same session by the same provider.
Unbundling: To inappropriately bill more CPT/HCPCS codes than necessary. Applied when certain codes represent procedures that are basic steps to accomplish a primary procedure already on the bill and, by definition, are included in the reimbursement of the primary procedure.
PROCEDURES AND RESPONSIBILITIES
When two or more related procedures are performed on a patient during a single session or visit, Oxford will reimburse the provider for the comprehensive code and deny or adjust the component, incidental or mutually exclusive procedure performed during the same session. The rebundling guidelines in this policy are based on The Correct Coding Initiative administered through the Centers for Medicare & Medicaid Services (CMS), AMA Current Procedural Terminology (CPT Code) and additional general industry accepted guidelines.
To rebundle a claim, Oxford claims system utilizes a software package assembled by IntelliClaim (owned by McKesson Health Solutions). IntelliClaim’s product provides a platform on which two off-the-shelf and widely used products (referenced below) are combined with a flexible environment that allows Oxford to develop, customize & update our payment guidelines as necessary. Through their product, the efficiency, accuracy and speed with which millions of edits can be applied, the detailed documentation supporting the logic behind the rules, and the clear explanations for claim adjustments result in more automated claim processing, faster turnaround, more consistent and understandable results, and improved customer service. As part of the IntelliClaim package, IntelliClaim has incorporated two software packages to rebundle codes. These software packages are the Correct Coding Initiative Software by The National Technical Information Service (NTIS) and effective October 6, 2006, ClaimsXten™ by McKesson.
The NTIS software provides Oxford with the Correct Coding Rules used by CMS. This software is the same software product used by fiscal intermediaries that process Medicare Fee for Service claims for CMS. The Correct Coding Rules can be found on CMS’s website at www.cms.gov. The IntelliClaim software incorporates the quarterly updates that CMS makes to the Correct Coding rules into Oxford’s claims processing system. ClaimsXten™ contains KnowledgePacks consisting of rules that, among other things, characterizes coding relationships on provider medical bills. ClaimsXten provides information that allows claims submitters, claims processors and adjudicators to identify potentially incorrect or inappropriate coding relationships by a single provider, for a single patient, on a single date of service. Examples of the rules include incidental, mutually exclusive, unbundling and visit edits. Sources of the KnowledgePacks include the AMA and CPT publications, CMS, specialty societies and McKesson physician consultants.
