Not overriding when you can means missing billable services. Check out these top three frequently asked questions -- and expert answers -- to increase your CCI know-how. 1. What Is a CCI Edit? Every quarter CCI puts out a list of code pairs that Medicare -- and many private payers -- follow when they reimburse physician practices. The CCI edits list pairs of CPT and HCPCS codes that payers will not pay on when you bill them together. Medicare and other payers apply these edits to services you bill for the same provider, for the same beneficiary, and on the same date of service. "All edits consist of code pairs that are arranged in two columns (Column 1 and Column 2)," explains Marvel J. Hammer, RN, CPC, CCS-P, PCS, ACS-PM, CHCO, consultant with MJH Consulting in Denver. "Codes that are listed in Column 2 are not payable if performed on the same day on the same patient by the same provider as the code listed in Column 1, unless the edits permit the use of a modifier associated with CCI." "The purpose of the NCCI edits is to prevent improper payment when incorrect code combinations are reported," CMS explains on its Web site. You can find the current listing of CCI edits, as well as the CCI policy manual, on the CMS Web site at www.cms.hhs.gov/NationalCorrectCodInitEd. CMS updates the CCI edits every quarter, and you should always consult the most recent version when coding. Important: 2. Why Are There 2 Types of Edits? CCI edits include two types of edits: mutually exclusive and "column 1/column 2" (previously known as "comprehensive/component") edits. Here's the difference: Column 1/column 2 edits describe "bundled"procedures. That is, CMS considers the code listed in column 2 included as a component of the more extensive column 1 procedure. For example, CCI bundles biopsy code 11100 (Biopsy of skin, subcutaneous tissue and/or mucous membrane [including simple closure], unless otherwise listed; single lesion) into lesion excision code 11403 (Excision, benign lesion including margins, except skin tag [unless listed else-where], trunk, arms or legs; excised diameter 2.1 to 3.0 cm). The first column in the CCI Excel spreadsheet "generally represents the major procedure or service" and the code in the second spreadsheet column "often represents the component part," Hammer says. "However, within the mutually exclusive edits table, the column 2 code generally represents the procedure or service with the higher work (relative value unit [RVU]) and is the nonpayable procedure or service when reported with the column 1 code." Payment woes: 3. Can I Ever Ignore the Edits? In certain clinical circumstances you can override -- not ignore -- CCI edits and receive separate reimbursement for bundled codes. To find out if you can separately bill services your physician performed, first check the "modifier indicator" in column F of the CCI spreadsheet. A "0" indicator means that you cannot unbundle the two codes under any circumstances. An indicator of "1," however, means that you may use a modifier to override the edit if the clinical circumstances warrant separate reimbursement, such as a separate encounter on the same date, a separate anatomical site, or a separate indication.
