Transcription

1 Companion Document 837I - Encounters 837I Institutional Health Care Claim - for Encounters Basic Instructions This section provides information to help you prepare for the ANSI ASC X12N 837 Health Care transaction for institutional encounters. The tables in this document provide information about 837 segments and data elements that require specific instructions to efficiently process. Use this companion document in conjunction with both the Transaction Set Implementation Guide Health Care Claim: Institutional, 837, ASC X12N 837 (004010X096), May 2000, and the subsequent Addenda (004010X096A1), October 2002, published by the Washington Publishing Co.

2 1 X12 and HIPAA Compliance Checking, and Business Edits Level 1. X12 Compliance: Anthem Blue Cross returns a 997 Functional Acknowledgment to the submitter for every inbound 837 transaction received. Each transaction passes through edits to ensure that it is X12 compliant. If it successfully passes X12 syntax edits, a 997 Functional Acknowledgement is returned indicating acceptance of the transaction. If the transaction fails X12 syntax compliance, the 997 Functional Acknowledgement will also report the Level 1 errors in the AK segments and, depending on where the error occurred, will indicate that the entire interchange, functional group or transaction set has been rejected. Level 2. HIPAA IG Compliance - Sets: HIPAA Implementation Guide edits are strictly enforced. Anthem Blue Cross will return a Level 2 Status Report to the submitter indicating if a transaction set has been accepted or rejected. If the transaction set has been rejected, this report will indicate the Level 2 HIPAA compliance error(s) that occurred. 2 HIPAA Compliant s Follow the 837 Institutional IG precisely. Use HIPAA-Compliant codes from current versions of the sources listed in the 837 Institutional IG, Appendix C: External Sources. Acceptance of HIPAA standard codes or modifiers will not alter Anthem Blue Cross covered benefits or current payment policies, guidelines or processes. 3 Uppercase Letters All alpha characters must be submitted in UPPERCASE letters only. 4 Delimiters Enterprise EDI Gateway/Clearinghouse accepts any of the standard delimiters as defined by the ANSI standards. The more commonly used delimiters include the following: Data Element Separator, Asterisk, (*) Sub-Element Separator, Vertical Bar, ( ) Segment Terminator, Tilde, (~) These delimiters are for illustration purposes only and are not specific recommendations or Page 2 of 20

3 requirements. 5 Coordination of Benefits Specific 837 data elements work together to coordinate benefits between Anthem Blue Cross and Medicare or other carriers. The tables in the section that follow (Loop 2320, 2330A, and 2330B), identify the data elements that pertain to coordination of benefits with Medicare (Provider-to-Payer-to- Payer COB model) and with other carriers (Payer-to-Provider-to-Payer COB model). Anthem Blue Cross recognizes submission of an 837 to a sequential payer populated with data from the previous payer s 835 (Health Care Claim Payment/Advice). Based on the information provided and the type of policy, the claim will be adjudicated without the paper copy of the Explanation of Benefits from Medicare or the primary carrier. When more than one payer is involved on a claim, payer sequencing is as follows: If a secondary payer is indicated, then all the data elements from the primary payer must also be present. If a tertiary payer is involved, then all the data elements from the primary and secondary payer must also be present. If these data elements are omitted, Anthem Blue Cross will fail the particular claim. 6 Taxonomy s (PRV) The Healthcare Provider Taxonomy code set divides health care providers into hierarchical groupings by type, classification, and specialization, and assigns a code to each grouping. The Taxonomy consists of two parts: individuals (e.g., physicians) and non-individuals (e.g., ambulatory health care facilities). All codes are alphanumeric and are 10 positions in length. These codes are not assigned to health care providers; rather, health care providers select the taxonomy code(s) that most closely represents their education, license, or certification. If a health care provider has more than one taxonomy code associated with it, a health plan may prefer that the health care provider use one over another when submitting claims for certain services. It is strongly recommended that the taxonomy be populated in Loops 2000A and 2310A PRV segment for all applicable claims that you are filing. Refer to the CMS website for a listing of codes, Taxonomy (PRV) 837I Institutional Claims The taxonomy should be populated in Loops 2000A and 2310A PRV segment for all applicable claims that you are filing. PRV Loop 2000A Billing/Pay-to Provider PRV01 = Provider BI Billing Provider Specialty Information PT Pay to Provider Specialty Information PRV02 = ZZ Health Care Provider Taxonomy code PRV03 = (Provider Taxonomy ) Strongly recommended to include a taxonomy on all applicable claims that you are filing (NOTE to Clearinghouses DO NOT USE Defaults) Example: PRV*BI*ZZ*203BA0200N~ PRV Loop 2310A Attending Provider PRV01 = Provider AT Attending Provider Specialty Information PRV02 = ZZ Health Care Provider Taxonomy code PRV03 = (Provider Taxonomy ) Strongly recommended to include a taxonomy on all applicable claims that you are filing (NOTE to Clearinghouses DO NOT USE Defaults) Example: PRV*AT*ZZ*363LP0200N~ Page 3 of 20

4 7 Numeric s, s and Unit Amounts Anthem Blue Cross accepts monetary amounts only in US dollars. If codes related to foreign currencies are used, then the encounter will be denied. Anthem Blue Cross recognizes unit amounts in whole numbers only. The encounter will also be denied for negative values submitted in any of the three data elements in Loop 2400, SV2 Institutional Service Line (See 837 Institutional IG, P.439): SV203 Line Item Charge Amount SV205 Quantity Service Unit Count SV207 Line Item Denied Charge or Non-Covered Charge Amount Page 4 of 20

9 837 Institutional Claim Header The 837 Claim Header identifies the start of a transaction, the specific transaction set, and its business purpose. Also, when a transaction set uses a hierarchical data structure, a data element in the header, BHT01 (Hierarchical Structure ) relates the type of business data expected within each level. The following table indicates the specific values of the required header segments and data elements for Anthem Blue Cross processing.
