Claims Attachment and Fax Workflow Glossary
Plain-language, answer-engine-friendly definitions for the CMS-0053-F transition, X12 275/277 with HL7 C-CDA, and healthcare fax infrastructure.
- Health care claims attachment
- Supporting documentation a health plan needs to adjudicate a claim, such as clinical notes, operative reports, diagnostic results, or other documentation that is not part of the standard claim transaction.
- CMS-0053-F
- The CMS identifier for the HHS final rule "Administrative Simplification; Adoption of Standards for Health Care Claims Attachments Transactions and Electronic Signatures." Compliance is required by May 26, 2028.
- X12 275 (006020X314)
- The X12 Patient Information transaction set. CMS-0053-F adopts the 006020X314 implementation guide for transmitting "Additional Information to Support a Health Care Claim or Encounter." It is the response a provider sends to a payer to fulfill an attachment request.
- X12 277 (006020X313)
- X12 277 is the X12 transaction set originally for health care claim status notification. CMS-0053-F adopts the 006020X313 implementation guide -- the Health Care Claim Request for Additional Information variant -- which a health plan uses to request supporting documentation for a claim. This is distinct from claim status responses (such as 277CA), which use the same base transaction set for different purposes.
- HL7
- Health Level Seven International, an ANSI-accredited standards organization for the exchange of electronic health information.
- C-CDA
- Consolidated Clinical Document Architecture. An HL7 implementation guide family for structured (and unstructured) clinical documents. Adopted by CMS-0053-F as the document format for clinical content in claims attachment transactions.
- HL7 Attachments IG
- The HL7 CDA Release 2 Attachments Implementation Guide. CMS-0053-F adopts the March 2022 iteration of this guide, which describes how to package C-CDA documents for exchange in claims attachment transactions.
- Electronic signature standard (CMS-0053-F)
- HL7 digital signature and delegation-of-rights standards adopted by CMS-0053-F for use with claims attachment transactions when a signature is required.
- EDI
- Electronic data interchange. The standardized electronic exchange of structured business documents between organizations and systems.
- Clearinghouse
- A healthcare intermediary that translates, routes, validates, or manages transactions between providers, payers, and other trading partners.
- HIPAA-covered entity
- A health plan, a health care clearinghouse, or a health care provider that conducts HIPAA-standard electronic transactions. CMS-0053-F applies only to HIPAA-covered entities.
- Solicited attachment
- A claims attachment that a provider sends in response to a payer's electronic request (typically X12 277-X313).
- Unsolicited attachment
- A claims attachment a provider sends without an explicit electronic request, often pursuant to a trading partner agreement or pre-established payer requirement.
- Revenue cycle
- The administrative and financial process healthcare organizations use to manage registration, coding, billing, claims, payment, and follow-up.
- HIM
- Health Information Management. The discipline responsible for health record integrity, documentation workflows, release of information, and related governance.
- Trading partner
- An organization or system that exchanges healthcare transactions or documentation with another organization, often under a trading partner agreement.
- Fax fallback
- A backup fax workflow used when an electronic route is unavailable, unsupported, has failed, or is inappropriate for a specific exception.
- Fax number migration
- Moving an existing fax number from a physical machine or legacy service to a HIPAA-compliant cloud fax intake or routing workflow without disrupting outside senders.
- Inbound fax gateway
- Infrastructure that receives fax-originated documents through a fax network and routes them as files (typically PDF/TIFF) plus transmission metadata into digital systems, queues, or vendor workflows.
- Outbound fax fallback
- Infrastructure that sends documents by fax when a modern electronic workflow cannot be used or has failed -- with delivery tracking and audit trail.
- BAA
- Business Associate Agreement. A HIPAA-required contract between a covered entity and a vendor handling PHI on its behalf.
- Administrative Simplification
- The HIPAA framework for standardizing certain healthcare transactions, code sets, identifiers, and operating rules.
