What healthcare terms are defined in the MedicalRecords.com glossary?

The MedicalRecords.com glossary covers medical records terminology, healthcare IT acronyms, insurance terms, clinical vocabulary, regulatory terms (HIPAA, HITECH), and EHR/EMR industry definitions. It is designed for patients, healthcare professionals, and technology buyers seeking clear explanations.

What does EMR stand for in healthcare?

EMR stands for Electronic Medical Record. It is a digital version of the paper charts kept in a clinician's office, containing a patient's medical and treatment history from a single practice. Unlike EHRs (Electronic Health Records), EMRs are not typically designed to share information outside the practice.

What is HIPAA and why does it matter for medical records?

HIPAA (Health Insurance Portability and Accountability Act) is a federal law that establishes standards to protect sensitive patient health information. Under HIPAA, patients have the right to access and obtain copies of their medical records, and covered entities must respond to records requests within 30 days.

What is the difference between an EHR and an EMR?

An EMR (Electronic Medical Record) is a digital record used within a single practice. An EHR (Electronic Health Record) is designed to be shared across multiple healthcare settings — different physicians, hospitals, labs, and specialists — giving a broader view of a patient's care history.
