Companion Document 835 835 Health Care Claim Payment/Advice Basic Instructions This section provides information to help you prepare for the ANSI ASC X12 Health Care Claim Payment/Advice (835) transaction. The remaining sections of this appendix include tables that provide information about 835 segments and data elements that are used to efficiently process transactions through Anthem Blue Cross and Blue Shield, Colorado and Nevada (West Region) systems. Use this companion document in conjunction with both the Transaction Set Implementation Guide “Health Care Claim Payment/Advice, 835, ASCX12N 835 (004010X091),” May 2000, and the subsequent Addenda (004010X091A1), October 2002, published by the Washington Publishing Co.

All trading partners are eligible to receive the ERA and payment by EFT but require prior registration with EDI Solutions, (800) 332-7575, for the necessary set up and instructions. As part of the process, the ERA/EFT Enrollment Form must be completed. It is available from the EDI website (http://www.anthem.com/edi, Register, Registration Form). Changes to the NPI, provider or tax identification numbers may affect the distribution of the 835 Payment/Advice, therefore, providers should notify Anthem Provider Services and EDI Solutions when these types of changes do occur. 2 Electronic Funds Transfer (EFT) In order to sign up for EFT, complete and submit the ERA/EFT Enrollment Form. The same form is used to submit any changes to your EFT setup. Questions about the direct deposit system can be made directly to (800) 332-7575. 3 Basic Format of the 835 File - Payment by NPI, Payee ID, Multiple Providers Claim payments are made based on the NPI (or Payee ID) and Tax ID Number. Depending on the reimbursement arrangement, multiple providers may be paid under their group NPI (or group Payee ID) and Tax ID. Therefore, when a provider group requests an 835, by default all provider payments linked to the group NPI (or group Payee ID) will appear on the 835. Note that all registered NPIs will be returned on the 835. The format of the 835 file will show multiple checks and/or payment information tied to the provider group or individual provider on a given day in one or multiple ERA files. Checks and/or payment information can be bundled and uniquely identified within the same 835 file. Multiple checks and/or payment information within one 835 file may cause difficulty and require system changes for providers who directly download 835 files. 4 Delimiters Anthem will use the delimiters as defined in the table below for all outbound transactions.

Specifically, the Claim Adjustment Group Code (CAS01) categorizes the adjustment reason codes contained in a particular CAS and are evaluated according to the following order: 1. Patient Responsibility (PR) — indicates the amount adjusted in CAS segment is the patient’s responsibility. 2. Contractual Obligations (CO) — indicates the amount adjusted in CAS segment is not the patient’s responsibility due to a contractual obligation between the provider and the payer. 3. Payer Initiated Reductions (PI) — indicates the amount adjusted in CAS segment is not the patient’s responsibility, without a supporting contract between the provider and the payer. 4. Correction and Reversals (CR) — indicates the claim is the reversal of a previously reported claim or claim payment. 5. Other Adjustments (OA) — indicates the amount adjusted does not fall in any of the above categories. 6 Claim Adjustment Reason Codes and Remittance Advice Remark Codes A claim adjustment reason code (CAS segment) is used to communicate that an adjustment was made at the claim/service line, and provides the reason for why the payment differs from what was billed. The adjustment reason code list is available on the internet (http://www.wpc-edi.com/ codes, select Claim Adjustment Reason Codes) and reviewed by the Claim Adjustment Status Code maintenance committee three times a year. A claim remittance advice remark code (LQ segment) provides supplemental explanation for an adjustment already described by an adjustment reason code. Previously, the remittance remark code list was created and supported for Medicare only, but now it is appropriate for use by all payers. The remark code list is available on the internet (http://www.wpc-edi.com/codes, select Remittance Advice Remark Codes) and reviewed by the Remittance Advice Code Maintenance Committee whose members represent various components from CMS. It is important to continue referring to the code lists maintained by the committees. Updated code lists are published tri-annually at the end of March, July, and November. The use of HIPAA standards has imposed a limitation on what detailed explanation is reported on the 835 Payment/Advice. It has been determined that proprietary disposition codes may not map onefor-one to a standard HIPAA claim adjustment reason and/or remittance advice remark code. Anthem Blue Cross and Blue Shield - West Region Page 3 of 13 Release 02 (February 2011) Version 004010A1 - Oct 2002 7 835 Health Care Claim Payment/Advice Companion Document Provider Level Adjustment (PLB) The provider level adjustment, PLB segment, is reported after all the claim payments in the Summary of the 835 transaction. This segment is used for takeback notification and actual takebacks, and the detailed information of the adjusted claim is reported at the claim level, CLP segment. Example: PLB03 Data Element PLB*941400001*20081231*WO:9730000048070714400575*1205.31 Provider Tax ID (EIN) End of Fiscal Year Adjusted Amount Adj Reas Code DCN Claim Date Patient Account # The third data element, PLB03, in the PLB segment is a composite segment with four distinct values, the Adjustment Reason Code, followed by a value composed of the Document Control Number (DCN), Claim Date, and Patient Account Number. PLB03-1: The Adjustment Reason Code (FB, IR, PI, L6, WO) identifies the type of adjustment. PLB03-2: DCN is the claim number Anthem uses to identify the payment made to the provider. Date of when the claim was originally processed (070714). Patient Account Number assigned by provider to track claim processing (400575). PLB04: 8 If the code is WO, then the adjusted amount is assumed to be negative. If the code is FB, then the adjusted amount will be preceded by a (-) sign when the adjustment is negative. The PLB will decrease when the adjustment amount is positive. The PLB will increase when the adjustment amount is negative. Balancing To ensure HIPAA compliance, editing is performed on the 835 transaction as it is routed through the Enterprise EDI Gateway/Clearinghouse. Successful outbound routing to the 835 trading partner depends on the balancing of the file where the total payment must agree with the remittance information detailing that payment. The amounts reported in the file must balance at three different levels; the service line, the claim, and the transaction. When service payment information is provided, the submitted service charge (SVC02) minus the sum of all monetary adjustments (CAS segments) must equal the amount paid for the service line (SVC03). Similarly within the claim payment loop, the submitted charge for the claim (CLP03) minus the sum of all monetary adjustments (CAS segments) must equal the claim paid amount (CLP04). The total claim charge (CLP03) must balance the sum of the related service charges (SVC02), if applicable. *Monetary amounts in the AMT segments convey information only; they do not affect the financial balancing of the transaction. Further balancing within the transaction ensures that the sum of all claim payments (CLP04) minus the sum of all provider level adjustments (PLB segments) equals the total payment amount (BPR02). All balancing measures must be met in order for an 835 file to be delivered to the Gateway.
