HL7, or Health Level Seven, refers to a set of international standards for the transfer of clinical and administrative data between software applications used by various healthcare providers. This standard facilitates interoperability among disparate healthcare systems, enabling them to communicate effectively, share patient information, and maintain data integrity. HL7 standards cover a wide range of healthcare data exchange needs, including messages about patient admissions, discharges, and lab results.

While ICD10CM, CPT4, and SNOMED are important coding systems in healthcare—ICD10CM is used primarily for diagnosis coding, CPT4 for procedure coding and billing, and SNOMED for comprehensive clinical terminology and healthcare concepts—they do not serve as interface standards for transmitting electronic data between systems. In contrast, HL7 focuses specifically on the protocols and formats necessary to ensure that data can be exchanged seamlessly and accurately within the healthcare environment. This makes HL7 the most relevant choice when it comes to interface standards in healthcare electronic data exchange.
